+description: Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Goal
+
+Identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (`spec.md`, `plan.md`, `tasks.md`) before implementation. This command MUST run only after `/tasks` has successfully produced a complete `tasks.md`.
+
+## Operating Constraints
+
+**STRICTLY READ-ONLY**: Do **not** modify any files. Output a structured analysis report. Offer an optional remediation plan (user must explicitly approve before any follow-up editing commands would be invoked manually).
+
+**Constitution Authority**: The project constitution (`.specify/memory/constitution.md`) is **non-negotiable** within this analysis scope. Constitution conflicts are automatically CRITICAL and require adjustment of the spec, plan, or tasks—not dilution, reinterpretation, or silent ignoring of the principle. If a principle itself needs to change, that must occur in a separate, explicit constitution update outside `/analyze`.
+
+## Execution Steps
+
+### 1. Initialize Analysis Context
+
+Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths:
+
+- SPEC = FEATURE_DIR/spec.md
+- PLAN = FEATURE_DIR/plan.md
+- TASKS = FEATURE_DIR/tasks.md
+
+Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command).
+For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+### 2. Load Artifacts (Progressive Disclosure)
+
+Load only the minimal necessary context from each artifact:
+
+**From spec.md:**
+
+- Overview/Context
+- Functional Requirements
+- Non-Functional Requirements
+- User Stories
+- Edge Cases (if present)
+
+**From plan.md:**
+
+- Architecture/stack choices
+- Data Model references
+- Phases
+- Technical constraints
+
+**From tasks.md:**
+
+- Task IDs
+- Descriptions
+- Phase grouping
+- Parallel markers [P]
+- Referenced file paths
+
+**From constitution:**
+
+- Load `.specify/memory/constitution.md` for principle validation
+
+### 3. Build Semantic Models
+
+Create internal representations (do not include raw artifacts in output):
+
+- **Requirements inventory**: Each functional + non-functional requirement with a stable key (derive slug based on imperative phrase; e.g., "User can upload file" → `user-can-upload-file`)
+- **User story/action inventory**: Discrete user actions with acceptance criteria
+- **Task coverage mapping**: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases)
+- **Constitution rule set**: Extract principle names and MUST/SHOULD normative statements
+
+### 4. Detection Passes (Token-Efficient Analysis)
+
+Focus on high-signal findings. Limit to 50 findings total; aggregate remainder in overflow summary.
+
+#### A. Duplication Detection
+
+- Identify near-duplicate requirements
+- Mark lower-quality phrasing for consolidation
+
+#### B. Ambiguity Detection
+
+- Flag vague adjectives (fast, scalable, secure, intuitive, robust) lacking measurable criteria
+- Flag unresolved placeholders (TODO, TKTK, ???, `<placeholder>`, etc.)
+
+#### C. Underspecification
+
+- Requirements with verbs but missing object or measurable outcome
+- User stories missing acceptance criteria alignment
+- Tasks referencing files or components not defined in spec/plan
+
+#### D. Constitution Alignment
+
+- Any requirement or plan element conflicting with a MUST principle
+- Missing mandated sections or quality gates from constitution
+
+#### E. Coverage Gaps
+
+- Requirements with zero associated tasks
+- Tasks with no mapped requirement/story
+- Non-functional requirements not reflected in tasks (e.g., performance, security)
+
+#### F. Inconsistency
+
+- Terminology drift (same concept named differently across files)
+- Data entities referenced in plan but absent in spec (or vice versa)
+- Task ordering contradictions (e.g., integration tasks before foundational setup tasks without dependency note)
+- Conflicting requirements (e.g., one requires Next.js while other specifies Vue)
+
+### 5. Severity Assignment
+
+Use this heuristic to prioritize findings:
+
+- **CRITICAL**: Violates constitution MUST, missing core spec artifact, or requirement with zero coverage that blocks baseline functionality
+- **HIGH**: Duplicate or conflicting requirement, ambiguous security/performance attribute, untestable acceptance criterion
+- **MEDIUM**: Terminology drift, missing non-functional task coverage, underspecified edge case
+- **LOW**: Style/wording improvements, minor redundancy not affecting execution order
+
+### 6. Produce Compact Analysis Report
+
+Output a Markdown report (no file writes) with the following structure:
+
+## Specification Analysis Report
+
+| ID | Category | Severity | Location(s) | Summary | Recommendation |
+|----|----------|----------|-------------|---------|----------------|
+| A1 | Duplication | HIGH | spec.md:L120-134 | Two similar requirements ... | Merge phrasing; keep clearer version |
+
+(Add one row per finding; generate stable IDs prefixed by category initial.)
+
+**Coverage Summary Table:**
+
+| Requirement Key | Has Task? | Task IDs | Notes |
+|-----------------|-----------|----------|-------|
+
+**Constitution Alignment Issues:** (if any)
+
+**Unmapped Tasks:** (if any)
+
+**Metrics:**
+
+- Total Requirements
+- Total Tasks
+- Coverage % (requirements with >=1 task)
+- Ambiguity Count
+- Duplication Count
+- Critical Issues Count
+
+### 7. Provide Next Actions
+
+At end of report, output a concise Next Actions block:
+
+- If CRITICAL issues exist: Recommend resolving before `/implement`
+- If only LOW/MEDIUM: User may proceed, but provide improvement suggestions
+- Provide explicit command suggestions: e.g., "Run /specify with refinement", "Run /plan to adjust architecture", "Manually edit tasks.md to add coverage for 'performance-metrics'"
+
+### 8. Offer Remediation
+
+Ask the user: "Would you like me to suggest concrete remediation edits for the top N issues?" (Do NOT apply them automatically.)
+
+## Operating Principles
+
+### Context Efficiency
+
+- **Minimal high-signal tokens**: Focus on actionable findings, not exhaustive documentation
+- **Progressive disclosure**: Load artifacts incrementally; don't dump all content into analysis
+- **Token-efficient output**: Limit findings table to 50 rows; summarize overflow
+- **Deterministic results**: Rerunning without changes should produce consistent IDs and counts
+
+### Analysis Guidelines
+
+- **NEVER modify files** (this is read-only analysis)
+- **NEVER hallucinate missing sections** (if absent, report them accurately)
+- **Prioritize constitution violations** (these are always CRITICAL)
+- **Use examples over exhaustive rules** (cite specific instances, not generic patterns)
+- **Report zero issues gracefully** (emit success report with coverage statistics)

+description: Generate a custom checklist for the current feature based on user requirements.
+---
+
+## Checklist Purpose: "Unit Tests for English"
+
+**CRITICAL CONCEPT**: Checklists are **UNIT TESTS FOR REQUIREMENTS WRITING** - they validate the quality, clarity, and completeness of requirements in a given domain.
+
+**NOT for verification/testing**:
+- ❌ NOT "Verify the button clicks correctly"
+- ❌ NOT "Test error handling works"
+- ❌ NOT "Confirm the API returns 200"
+- ❌ NOT checking if code/implementation matches the spec
+
+**FOR requirements quality validation**:
+- ✅ "Are visual hierarchy requirements defined for all card types?" (completeness)
+- ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
+- ✅ "Are hover state requirements consistent across all interactive elements?" (consistency)
+- ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage)
+- ✅ "Does the spec define what happens when logo image fails to load?" (edge cases)
+
+**Metaphor**: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Execution Steps
+
+1. **Setup**: Run `.specify/scripts/bash/check-prerequisites.sh --json` from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS list.
+   - All file paths must be absolute.
+   - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Clarify intent (dynamic)**: Derive up to THREE initial contextual clarifying questions (no pre-baked catalog). They MUST:
+   - Be generated from the user's phrasing + extracted signals from spec/plan/tasks
+   - Only ask about information that materially changes checklist content
+   - Be skipped individually if already unambiguous in `$ARGUMENTS`
+   - Prefer precision over breadth
+
+   Generation algorithm:
+   1. Extract signals: feature domain keywords (e.g., auth, latency, UX, API), risk indicators ("critical", "must", "compliance"), stakeholder hints ("QA", "review", "security team"), and explicit deliverables ("a11y", "rollback", "contracts").
+   2. Cluster signals into candidate focus areas (max 4) ranked by relevance.
+   3. Identify probable audience & timing (author, reviewer, QA, release) if not explicit.
+   4. Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries, measurable acceptance criteria.
+   5. Formulate questions chosen from these archetypes:
+      - Scope refinement (e.g., "Should this include integration touchpoints with X and Y or stay limited to local module correctness?")
+      - Risk prioritization (e.g., "Which of these potential risk areas should receive mandatory gating checks?")
+      - Depth calibration (e.g., "Is this a lightweight pre-commit sanity list or a formal release gate?")
+      - Audience framing (e.g., "Will this be used by the author only or peers during PR review?")
+      - Boundary exclusion (e.g., "Should we explicitly exclude performance tuning items this round?")
+      - Scenario class gap (e.g., "No recovery flows detected—are rollback / partial failure paths in scope?")
+
+   Question formatting rules:
+   - If presenting options, generate a compact table with columns: Option | Candidate | Why It Matters
+   - Limit to A–E options maximum; omit table if a free-form answer is clearer
+   - Never ask the user to restate what they already said
+   - Avoid speculative categories (no hallucination). If uncertain, ask explicitly: "Confirm whether X belongs in scope."
+
+   Defaults when interaction impossible:
+   - Depth: Standard
+   - Audience: Reviewer (PR) if code-related; Author otherwise
+   - Focus: Top 2 relevance clusters
+
+   Output the questions (label Q1/Q2/Q3). After answers: if ≥2 scenario classes (Alternate / Exception / Recovery / Non-Functional domain) remain unclear, you MAY ask up to TWO more targeted follow‑ups (Q4/Q5) with a one-line justification each (e.g., "Unresolved recovery path risk"). Do not exceed five total questions. Skip escalation if user explicitly declines more.
+
+3. **Understand user request**: Combine `$ARGUMENTS` + clarifying answers:
+   - Derive checklist theme (e.g., security, review, deploy, ux)
+   - Consolidate explicit must-have items mentioned by user
+   - Map focus selections to category scaffolding
+   - Infer any missing context from spec/plan/tasks (do NOT hallucinate)
+
+4. **Load feature context**: Read from FEATURE_DIR:
+   - spec.md: Feature requirements and scope
+   - plan.md (if exists): Technical details, dependencies
+   - tasks.md (if exists): Implementation tasks
+   
+   **Context Loading Strategy**:
+   - Load only necessary portions relevant to active focus areas (avoid full-file dumping)
+   - Prefer summarizing long sections into concise scenario/requirement bullets
+   - Use progressive disclosure: add follow-on retrieval only if gaps detected
+   - If source docs are large, generate interim summary items instead of embedding raw text
+
+5. **Generate checklist** - Create "Unit Tests for Requirements":
+   - Create `FEATURE_DIR/checklists/` directory if it doesn't exist
+   - Generate unique checklist filename:
+     - Use short, descriptive name based on domain (e.g., `ux.md`, `api.md`, `security.md`)
+     - Format: `[domain].md` 
+     - If file exists, append to existing file
+   - Number items sequentially starting from CHK001
+   - Each `/speckit.checklist` run creates a NEW file (never overwrites existing checklists)
+
+   **CORE PRINCIPLE - Test the Requirements, Not the Implementation**:
+   Every checklist item MUST evaluate the REQUIREMENTS THEMSELVES for:
+   - **Completeness**: Are all necessary requirements present?
+   - **Clarity**: Are requirements unambiguous and specific?
+   - **Consistency**: Do requirements align with each other?
+   - **Measurability**: Can requirements be objectively verified?
+   - **Coverage**: Are all scenarios/edge cases addressed?
+   
+   **Category Structure** - Group items by requirement quality dimensions:
+   - **Requirement Completeness** (Are all necessary requirements documented?)
+   - **Requirement Clarity** (Are requirements specific and unambiguous?)
+   - **Requirement Consistency** (Do requirements align without conflicts?)
+   - **Acceptance Criteria Quality** (Are success criteria measurable?)
+   - **Scenario Coverage** (Are all flows/cases addressed?)
+   - **Edge Case Coverage** (Are boundary conditions defined?)
+   - **Non-Functional Requirements** (Performance, Security, Accessibility, etc. - are they specified?)
+   - **Dependencies & Assumptions** (Are they documented and validated?)
+   - **Ambiguities & Conflicts** (What needs clarification?)
+   
+   **HOW TO WRITE CHECKLIST ITEMS - "Unit Tests for English"**:
+   
+   ❌ **WRONG** (Testing implementation):
+   - "Verify landing page displays 3 episode cards"
+   - "Test hover states work on desktop"
+   - "Confirm logo click navigates home"
+   
+   ✅ **CORRECT** (Testing requirements quality):
+   - "Are the exact number and layout of featured episodes specified?" [Completeness]
+   - "Is 'prominent display' quantified with specific sizing/positioning?" [Clarity]
+   - "Are hover state requirements consistent across all interactive elements?" [Consistency]
+   - "Are keyboard navigation requirements defined for all interactive UI?" [Coverage]
+   - "Is the fallback behavior specified when logo image fails to load?" [Edge Cases]
+   - "Are loading states defined for asynchronous episode data?" [Completeness]
+   - "Does the spec define visual hierarchy for competing UI elements?" [Clarity]
+   
+   **ITEM STRUCTURE**:
+   Each item should follow this pattern:
+   - Question format asking about requirement quality
+   - Focus on what's WRITTEN (or not written) in the spec/plan
+   - Include quality dimension in brackets [Completeness/Clarity/Consistency/etc.]
+   - Reference spec section `[Spec §X.Y]` when checking existing requirements
+   - Use `[Gap]` marker when checking for missing requirements
+   
+   **EXAMPLES BY QUALITY DIMENSION**:
+   
+   Completeness:
+   - "Are error handling requirements defined for all API failure modes? [Gap]"
+   - "Are accessibility requirements specified for all interactive elements? [Completeness]"
+   - "Are mobile breakpoint requirements defined for responsive layouts? [Gap]"
+   
+   Clarity:
+   - "Is 'fast loading' quantified with specific timing thresholds? [Clarity, Spec §NFR-2]"
+   - "Are 'related episodes' selection criteria explicitly defined? [Clarity, Spec §FR-5]"
+   - "Is 'prominent' defined with measurable visual properties? [Ambiguity, Spec §FR-4]"
+   
+   Consistency:
+   - "Do navigation requirements align across all pages? [Consistency, Spec §FR-10]"
+   - "Are card component requirements consistent between landing and detail pages? [Consistency]"
+   
+   Coverage:
+   - "Are requirements defined for zero-state scenarios (no episodes)? [Coverage, Edge Case]"
+   - "Are concurrent user interaction scenarios addressed? [Coverage, Gap]"
+   - "Are requirements specified for partial data loading failures? [Coverage, Exception Flow]"
+   
+   Measurability:
+   - "Are visual hierarchy requirements measurable/testable? [Acceptance Criteria, Spec §FR-1]"
+   - "Can 'balanced visual weight' be objectively verified? [Measurability, Spec §FR-2]"
+
+   **Scenario Classification & Coverage** (Requirements Quality Focus):
+   - Check if requirements exist for: Primary, Alternate, Exception/Error, Recovery, Non-Functional scenarios
+   - For each scenario class, ask: "Are [scenario type] requirements complete, clear, and consistent?"
+   - If scenario class missing: "Are [scenario type] requirements intentionally excluded or missing? [Gap]"
+   - Include resilience/rollback when state mutation occurs: "Are rollback requirements defined for migration failures? [Gap]"
+
+   **Traceability Requirements**:
+   - MINIMUM: ≥80% of items MUST include at least one traceability reference
+   - Each item should reference: spec section `[Spec §X.Y]`, or use markers: `[Gap]`, `[Ambiguity]`, `[Conflict]`, `[Assumption]`
+   - If no ID system exists: "Is a requirement & acceptance criteria ID scheme established? [Traceability]"
+
+   **Surface & Resolve Issues** (Requirements Quality Problems):
+   Ask questions about the requirements themselves:
+   - Ambiguities: "Is the term 'fast' quantified with specific metrics? [Ambiguity, Spec §NFR-1]"
+   - Conflicts: "Do navigation requirements conflict between §FR-10 and §FR-10a? [Conflict]"
+   - Assumptions: "Is the assumption of 'always available podcast API' validated? [Assumption]"
+   - Dependencies: "Are external podcast API requirements documented? [Dependency, Gap]"
+   - Missing definitions: "Is 'visual hierarchy' defined with measurable criteria? [Gap]"
+
+   **Content Consolidation**:
+   - Soft cap: If raw candidate items > 40, prioritize by risk/impact
+   - Merge near-duplicates checking the same requirement aspect
+   - If >5 low-impact edge cases, create one item: "Are edge cases X, Y, Z addressed in requirements? [Coverage]"
+
+   **🚫 ABSOLUTELY PROHIBITED** - These make it an implementation test, not a requirements test:
+   - ❌ Any item starting with "Verify", "Test", "Confirm", "Check" + implementation behavior
+   - ❌ References to code execution, user actions, system behavior
+   - ❌ "Displays correctly", "works properly", "functions as expected"
+   - ❌ "Click", "navigate", "render", "load", "execute"
+   - ❌ Test cases, test plans, QA procedures
+   - ❌ Implementation details (frameworks, APIs, algorithms)
+   
+   **✅ REQUIRED PATTERNS** - These test requirements quality:
+   - ✅ "Are [requirement type] defined/specified/documented for [scenario]?"
+   - ✅ "Is [vague term] quantified/clarified with specific criteria?"
+   - ✅ "Are requirements consistent between [section A] and [section B]?"
+   - ✅ "Can [requirement] be objectively measured/verified?"
+   - ✅ "Are [edge cases/scenarios] addressed in requirements?"
+   - ✅ "Does the spec define [missing aspect]?"
+
+6. **Structure Reference**: Generate the checklist following the canonical template in `.specify/templates/checklist-template.md` for title, meta section, category headings, and ID formatting. If template is unavailable, use: H1 title, purpose/created meta lines, `##` category sections containing `- [ ] CHK### <requirement item>` lines with globally incrementing IDs starting at CHK001.
+
+7. **Report**: Output full path to created checklist, item count, and remind user that each run creates a new file. Summarize:
+   - Focus areas selected
+   - Depth level
+   - Actor/timing
+   - Any explicit user-specified must-have items incorporated
+
+**Important**: Each `/speckit.checklist` command invocation creates a checklist file using short, descriptive names unless file already exists. This allows:
+
+- Multiple checklists of different types (e.g., `ux.md`, `test.md`, `security.md`)
+- Simple, memorable filenames that indicate checklist purpose
+- Easy identification and navigation in the `checklists/` folder
+
+To avoid clutter, use descriptive types and clean up obsolete checklists when done.
+
+## Example Checklist Types & Sample Items
+
+**UX Requirements Quality:** `ux.md`
+
+Sample items (testing the requirements, NOT the implementation):
+- "Are visual hierarchy requirements defined with measurable criteria? [Clarity, Spec §FR-1]"
+- "Is the number and positioning of UI elements explicitly specified? [Completeness, Spec §FR-1]"
+- "Are interaction state requirements (hover, focus, active) consistently defined? [Consistency]"
+- "Are accessibility requirements specified for all interactive elements? [Coverage, Gap]"
+- "Is fallback behavior defined when images fail to load? [Edge Case, Gap]"
+- "Can 'prominent display' be objectively measured? [Measurability, Spec §FR-4]"
+
+**API Requirements Quality:** `api.md`
+
+Sample items:
+- "Are error response formats specified for all failure scenarios? [Completeness]"
+- "Are rate limiting requirements quantified with specific thresholds? [Clarity]"
+- "Are authentication requirements consistent across all endpoints? [Consistency]"
+- "Are retry/timeout requirements defined for external dependencies? [Coverage, Gap]"
+- "Is versioning strategy documented in requirements? [Gap]"
+
+**Performance Requirements Quality:** `performance.md`
+
+Sample items:
+- "Are performance requirements quantified with specific metrics? [Clarity]"
+- "Are performance targets defined for all critical user journeys? [Coverage]"
+- "Are performance requirements under different load conditions specified? [Completeness]"
+- "Can performance requirements be objectively measured? [Measurability]"
+- "Are degradation requirements defined for high-load scenarios? [Edge Case, Gap]"
+
+**Security Requirements Quality:** `security.md`
+
+Sample items:
+- "Are authentication requirements specified for all protected resources? [Coverage]"
+- "Are data protection requirements defined for sensitive information? [Completeness]"
+- "Is the threat model documented and requirements aligned to it? [Traceability]"
+- "Are security requirements consistent with compliance obligations? [Consistency]"
+- "Are security failure/breach response requirements defined? [Gap, Exception Flow]"
+
+## Anti-Examples: What NOT To Do
+
+**❌ WRONG - These test implementation, not requirements:**
+
+```markdown
+- [ ] CHK001 - Verify landing page displays 3 episode cards [Spec §FR-001]
+- [ ] CHK002 - Test hover states work correctly on desktop [Spec §FR-003]
+- [ ] CHK003 - Confirm logo click navigates to home page [Spec §FR-010]
+- [ ] CHK004 - Check that related episodes section shows 3-5 items [Spec §FR-005]
+```
+
+**✅ CORRECT - These test requirements quality:**
+
+```markdown
+- [ ] CHK001 - Are the number and layout of featured episodes explicitly specified? [Completeness, Spec §FR-001]
+- [ ] CHK002 - Are hover state requirements consistently defined for all interactive elements? [Consistency, Spec §FR-003]
+- [ ] CHK003 - Are navigation requirements clear for all clickable brand elements? [Clarity, Spec §FR-010]
+- [ ] CHK004 - Is the selection criteria for related episodes documented? [Gap, Spec §FR-005]
+- [ ] CHK005 - Are loading state requirements defined for asynchronous episode data? [Gap]
+- [ ] CHK006 - Can "visual hierarchy" requirements be objectively measured? [Measurability, Spec §FR-001]
+```
+
+**Key Differences:**
+- Wrong: Tests if the system works correctly
+- Correct: Tests if the requirements are written correctly
+- Wrong: Verification of behavior
+- Correct: Validation of requirement quality
+- Wrong: "Does it do X?" 
+- Correct: "Is X clearly specified?"

+description: Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+Goal: Detect and reduce ambiguity or missing decision points in the active feature specification and record the clarifications directly in the spec file.
+
+Note: This clarification workflow is expected to run (and be completed) BEFORE invoking `/speckit.plan`. If the user explicitly states they are skipping clarification (e.g., exploratory spike), you may proceed, but must warn that downstream rework risk increases.
+
+Execution steps:
+
+1. Run `.specify/scripts/bash/check-prerequisites.sh --json --paths-only` from repo root **once** (combined `--json --paths-only` mode / `-Json -PathsOnly`). Parse minimal JSON payload fields:
+   - `FEATURE_DIR`
+   - `FEATURE_SPEC`
+   - (Optionally capture `IMPL_PLAN`, `TASKS` for future chained flows.)
+   - If JSON parsing fails, abort and instruct user to re-run `/speckit.specify` or verify feature branch environment.
+   - For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. Load the current spec file. Perform a structured ambiguity & coverage scan using this taxonomy. For each category, mark status: Clear / Partial / Missing. Produce an internal coverage map used for prioritization (do not output raw map unless no questions will be asked).
+
+   Functional Scope & Behavior:
+   - Core user goals & success criteria
+   - Explicit out-of-scope declarations
+   - User roles / personas differentiation
+
+   Domain & Data Model:
+   - Entities, attributes, relationships
+   - Identity & uniqueness rules
+   - Lifecycle/state transitions
+   - Data volume / scale assumptions
+
+   Interaction & UX Flow:
+   - Critical user journeys / sequences
+   - Error/empty/loading states
+   - Accessibility or localization notes
+
+   Non-Functional Quality Attributes:
+   - Performance (latency, throughput targets)
+   - Scalability (horizontal/vertical, limits)
+   - Reliability & availability (uptime, recovery expectations)
+   - Observability (logging, metrics, tracing signals)
+   - Security & privacy (authN/Z, data protection, threat assumptions)
+   - Compliance / regulatory constraints (if any)
+
+   Integration & External Dependencies:
+   - External services/APIs and failure modes
+   - Data import/export formats
+   - Protocol/versioning assumptions
+
+   Edge Cases & Failure Handling:
+   - Negative scenarios
+   - Rate limiting / throttling
+   - Conflict resolution (e.g., concurrent edits)
+
+   Constraints & Tradeoffs:
+   - Technical constraints (language, storage, hosting)
+   - Explicit tradeoffs or rejected alternatives
+
+   Terminology & Consistency:
+   - Canonical glossary terms
+   - Avoided synonyms / deprecated terms
+
+   Completion Signals:
+   - Acceptance criteria testability
+   - Measurable Definition of Done style indicators
+
+   Misc / Placeholders:
+   - TODO markers / unresolved decisions
+   - Ambiguous adjectives ("robust", "intuitive") lacking quantification
+
+   For each category with Partial or Missing status, add a candidate question opportunity unless:
+   - Clarification would not materially change implementation or validation strategy
+   - Information is better deferred to planning phase (note internally)
+
+3. Generate (internally) a prioritized queue of candidate clarification questions (maximum 5). Do NOT output them all at once. Apply these constraints:
+    - Maximum of 10 total questions across the whole session.
+    - Each question must be answerable with EITHER:
+       * A short multiple‑choice selection (2–5 distinct, mutually exclusive options), OR
+       * A one-word / short‑phrase answer (explicitly constrain: "Answer in <=5 words").
+   - Only include questions whose answers materially impact architecture, data modeling, task decomposition, test design, UX behavior, operational readiness, or compliance validation.
+   - Ensure category coverage balance: attempt to cover the highest impact unresolved categories first; avoid asking two low-impact questions when a single high-impact area (e.g., security posture) is unresolved.
+   - Exclude questions already answered, trivial stylistic preferences, or plan-level execution details (unless blocking correctness).
+   - Favor clarifications that reduce downstream rework risk or prevent misaligned acceptance tests.
+   - If more than 5 categories remain unresolved, select the top 5 by (Impact * Uncertainty) heuristic.
+
+4. Sequential questioning loop (interactive):
+    - Present EXACTLY ONE question at a time.
+    - For multiple‑choice questions render options as a Markdown table:
+
+       | Option | Description |
+       |--------|-------------|
+       | A | <Option A description> |
+       | B | <Option B description> |
+       | C | <Option C description> | (add D/E as needed up to 5)
+       | Short | Provide a different short answer (<=5 words) | (Include only if free-form alternative is appropriate)
+
+    - For short‑answer style (no meaningful discrete options), output a single line after the question: `Format: Short answer (<=5 words)`.
+    - After the user answers:
+       * Validate the answer maps to one option or fits the <=5 word constraint.
+       * If ambiguous, ask for a quick disambiguation (count still belongs to same question; do not advance).
+       * Once satisfactory, record it in working memory (do not yet write to disk) and move to the next queued question.
+    - Stop asking further questions when:
+       * All critical ambiguities resolved early (remaining queued items become unnecessary), OR
+       * User signals completion ("done", "good", "no more"), OR
+       * You reach 5 asked questions.
+    - Never reveal future queued questions in advance.
+    - If no valid questions exist at start, immediately report no critical ambiguities.
+
+5. Integration after EACH accepted answer (incremental update approach):
+    - Maintain in-memory representation of the spec (loaded once at start) plus the raw file contents.
+    - For the first integrated answer in this session:
+       * Ensure a `## Clarifications` section exists (create it just after the highest-level contextual/overview section per the spec template if missing).
+       * Under it, create (if not present) a `### Session YYYY-MM-DD` subheading for today.
+    - Append a bullet line immediately after acceptance: `- Q: <question> → A: <final answer>`.
+    - Then immediately apply the clarification to the most appropriate section(s):
+       * Functional ambiguity → Update or add a bullet in Functional Requirements.
+       * User interaction / actor distinction → Update User Stories or Actors subsection (if present) with clarified role, constraint, or scenario.
+       * Data shape / entities → Update Data Model (add fields, types, relationships) preserving ordering; note added constraints succinctly.
+       * Non-functional constraint → Add/modify measurable criteria in Non-Functional / Quality Attributes section (convert vague adjective to metric or explicit target).
+       * Edge case / negative flow → Add a new bullet under Edge Cases / Error Handling (or create such subsection if template provides placeholder for it).
+       * Terminology conflict → Normalize term across spec; retain original only if necessary by adding `(formerly referred to as "X")` once.
+    - If the clarification invalidates an earlier ambiguous statement, replace that statement instead of duplicating; leave no obsolete contradictory text.
+    - Save the spec file AFTER each integration to minimize risk of context loss (atomic overwrite).
+    - Preserve formatting: do not reorder unrelated sections; keep heading hierarchy intact.
+    - Keep each inserted clarification minimal and testable (avoid narrative drift).
+
+6. Validation (performed after EACH write plus final pass):
+   - Clarifications session contains exactly one bullet per accepted answer (no duplicates).
+   - Total asked (accepted) questions ≤ 5.
+   - Updated sections contain no lingering vague placeholders the new answer was meant to resolve.
+   - No contradictory earlier statement remains (scan for now-invalid alternative choices removed).
+   - Markdown structure valid; only allowed new headings: `## Clarifications`, `### Session YYYY-MM-DD`.
+   - Terminology consistency: same canonical term used across all updated sections.
+
+7. Write the updated spec back to `FEATURE_SPEC`.
+
+8. Report completion (after questioning loop ends or early termination):
+   - Number of questions asked & answered.
+   - Path to updated spec.
+   - Sections touched (list names).
+   - Coverage summary table listing each taxonomy category with Status: Resolved (was Partial/Missing and addressed), Deferred (exceeds question quota or better suited for planning), Clear (already sufficient), Outstanding (still Partial/Missing but low impact).
+   - If any Outstanding or Deferred remain, recommend whether to proceed to `/speckit.plan` or run `/speckit.clarify` again later post-plan.
+   - Suggested next command.
+
+Behavior rules:
+- If no meaningful ambiguities found (or all potential questions would be low-impact), respond: "No critical ambiguities detected worth formal clarification." and suggest proceeding.
+- If spec file missing, instruct user to run `/speckit.specify` first (do not create a new spec here).
+- Never exceed 5 total asked questions (clarification retries for a single question do not count as new questions).
+- Avoid speculative tech stack questions unless the absence blocks functional clarity.
+- Respect user early termination signals ("stop", "done", "proceed").
+ - If no questions asked due to full coverage, output a compact coverage summary (all categories Clear) then suggest advancing.
+ - If quota reached with unresolved high-impact categories remaining, explicitly flag them under Deferred with rationale.

+description: Create or update the project constitution from interactive or provided principle inputs, ensuring all dependent templates stay in sync.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+You are updating the project constitution at `.specify/memory/constitution.md`. This file is a TEMPLATE containing placeholder tokens in square brackets (e.g. `[PROJECT_NAME]`, `[PRINCIPLE_1_NAME]`). Your job is to (a) collect/derive concrete values, (b) fill the template precisely, and (c) propagate any amendments across dependent artifacts.
+
+Follow this execution flow:
+
+1. Load the existing constitution template at `.specify/memory/constitution.md`.
+   - Identify every placeholder token of the form `[ALL_CAPS_IDENTIFIER]`.
+   **IMPORTANT**: The user might require less or more principles than the ones used in the template. If a number is specified, respect that - follow the general template. You will update the doc accordingly.
+
+2. Collect/derive values for placeholders:
+   - If user input (conversation) supplies a value, use it.
+   - Otherwise infer from existing repo context (README, docs, prior constitution versions if embedded).
+   - For governance dates: `RATIFICATION_DATE` is the original adoption date (if unknown ask or mark TODO), `LAST_AMENDED_DATE` is today if changes are made, otherwise keep previous.
+   - `CONSTITUTION_VERSION` must increment according to semantic versioning rules:
+     * MAJOR: Backward incompatible governance/principle removals or redefinitions.
+     * MINOR: New principle/section added or materially expanded guidance.
+     * PATCH: Clarifications, wording, typo fixes, non-semantic refinements.
+   - If version bump type ambiguous, propose reasoning before finalizing.
+
+3. Draft the updated constitution content:
+   - Replace every placeholder with concrete text (no bracketed tokens left except intentionally retained template slots that the project has chosen not to define yet—explicitly justify any left).
+   - Preserve heading hierarchy and comments can be removed once replaced unless they still add clarifying guidance.
+   - Ensure each Principle section: succinct name line, paragraph (or bullet list) capturing non‑negotiable rules, explicit rationale if not obvious.
+   - Ensure Governance section lists amendment procedure, versioning policy, and compliance review expectations.
+
+4. Consistency propagation checklist (convert prior checklist into active validations):
+   - Read `.specify/templates/plan-template.md` and ensure any "Constitution Check" or rules align with updated principles.
+   - Read `.specify/templates/spec-template.md` for scope/requirements alignment—update if constitution adds/removes mandatory sections or constraints.
+   - Read `.specify/templates/tasks-template.md` and ensure task categorization reflects new or removed principle-driven task types (e.g., observability, versioning, testing discipline).
+   - Read each command file in `.specify/templates/commands/*.md` (including this one) to verify no outdated references (agent-specific names like CLAUDE only) remain when generic guidance is required.
+   - Read any runtime guidance docs (e.g., `README.md`, `docs/quickstart.md`, or agent-specific guidance files if present). Update references to principles changed.
+
+5. Produce a Sync Impact Report (prepend as an HTML comment at top of the constitution file after update):
+   - Version change: old → new
+   - List of modified principles (old title → new title if renamed)
+   - Added sections
+   - Removed sections
+   - Templates requiring updates (✅ updated / ⚠ pending) with file paths
+   - Follow-up TODOs if any placeholders intentionally deferred.
+
+6. Validation before final output:
+   - No remaining unexplained bracket tokens.
+   - Version line matches report.
+   - Dates ISO format YYYY-MM-DD.
+   - Principles are declarative, testable, and free of vague language ("should" → replace with MUST/SHOULD rationale where appropriate).
+
+7. Write the completed constitution back to `.specify/memory/constitution.md` (overwrite).
+
+8. Output a final summary to the user with:
+   - New version and bump rationale.
+   - Any files flagged for manual follow-up.
+   - Suggested commit message (e.g., `docs: amend constitution to vX.Y.Z (principle additions + governance update)`).
+
+Formatting & Style Requirements:
+- Use Markdown headings exactly as in the template (do not demote/promote levels).
+- Wrap long rationale lines to keep readability (<100 chars ideally) but do not hard enforce with awkward breaks.
+- Keep a single blank line between sections.
+- Avoid trailing whitespace.
+
+If the user supplies partial updates (e.g., only one principle revision), still perform validation and version decision steps.
+
+If critical info missing (e.g., ratification date truly unknown), insert `TODO(<FIELD_NAME>): explanation` and include in the Sync Impact Report under deferred items.
+
+Do not create a new template; always operate on the existing `.specify/memory/constitution.md` file.

+description: Execute the implementation plan by processing and executing all tasks defined in tasks.md
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+1. Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Check checklists status** (if FEATURE_DIR/checklists/ exists):
+   - Scan all checklist files in the checklists/ directory
+   - For each checklist, count:
+     * Total items: All lines matching `- [ ]` or `- [X]` or `- [x]`
+     * Completed items: Lines matching `- [X]` or `- [x]`
+     * Incomplete items: Lines matching `- [ ]`
+   - Create a status table:
+     ```
+     | Checklist | Total | Completed | Incomplete | Status |
+     |-----------|-------|-----------|------------|--------|
+     | ux.md     | 12    | 12        | 0          | ✓ PASS |
+     | test.md   | 8     | 5         | 3          | ✗ FAIL |
+     | security.md | 6   | 6         | 0          | ✓ PASS |
+     ```
+   - Calculate overall status:
+     * **PASS**: All checklists have 0 incomplete items
+     * **FAIL**: One or more checklists have incomplete items
+   
+   - **If any checklist is incomplete**:
+     * Display the table with incomplete item counts
+     * **STOP** and ask: "Some checklists are incomplete. Do you want to proceed with implementation anyway? (yes/no)"
+     * Wait for user response before continuing
+     * If user says "no" or "wait" or "stop", halt execution
+     * If user says "yes" or "proceed" or "continue", proceed to step 3
+   
+   - **If all checklists are complete**:
+     * Display the table showing all checklists passed
+     * Automatically proceed to step 3
+
+3. Load and analyze the implementation context:
+   - **REQUIRED**: Read tasks.md for the complete task list and execution plan
+   - **REQUIRED**: Read plan.md for tech stack, architecture, and file structure
+   - **IF EXISTS**: Read data-model.md for entities and relationships
+   - **IF EXISTS**: Read contracts/ for API specifications and test requirements
+   - **IF EXISTS**: Read research.md for technical decisions and constraints
+   - **IF EXISTS**: Read quickstart.md for integration scenarios
+
+4. Parse tasks.md structure and extract:
+   - **Task phases**: Setup, Tests, Core, Integration, Polish
+   - **Task dependencies**: Sequential vs parallel execution rules
+   - **Task details**: ID, description, file paths, parallel markers [P]
+   - **Execution flow**: Order and dependency requirements
+
+5. Execute implementation following the task plan:
+   - **Phase-by-phase execution**: Complete each phase before moving to the next
+   - **Respect dependencies**: Run sequential tasks in order, parallel tasks [P] can run together  
+   - **Follow TDD approach**: Execute test tasks before their corresponding implementation tasks
+   - **File-based coordination**: Tasks affecting the same files must run sequentially
+   - **Validation checkpoints**: Verify each phase completion before proceeding
+
+6. Implementation execution rules:
+   - **Setup first**: Initialize project structure, dependencies, configuration
+   - **Tests before code**: If you need to write tests for contracts, entities, and integration scenarios
+   - **Core development**: Implement models, services, CLI commands, endpoints
+   - **Integration work**: Database connections, middleware, logging, external services
+   - **Polish and validation**: Unit tests, performance optimization, documentation
+
+7. Progress tracking and error handling:
+   - Report progress after each completed task
+   - Halt execution if any non-parallel task fails
+   - For parallel tasks [P], continue with successful tasks, report failed ones
+   - Provide clear error messages with context for debugging
+   - Suggest next steps if implementation cannot proceed
+   - **IMPORTANT** For completed tasks, make sure to mark the task off as [X] in the tasks file.
+
+8. Completion validation:
+   - Verify all required tasks are completed
+   - Check that implemented features match the original specification
+   - Validate that tests pass and coverage meets requirements
+   - Confirm the implementation follows the technical plan
+   - Report final status with summary of completed work
+
+Note: This command assumes a complete task breakdown exists in tasks.md. If tasks are incomplete or missing, suggest running `/tasks` first to regenerate the task list.

+description: Execute the implementation planning workflow using the plan template to generate design artifacts.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+1. **Setup**: Run `.specify/scripts/bash/setup-plan.sh --json` from repo root and parse JSON for FEATURE_SPEC, IMPL_PLAN, SPECS_DIR, BRANCH. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Load context**: Read FEATURE_SPEC and `.specify.specify/memory/constitution.md`. Load IMPL_PLAN template (already copied).
+
+3. **Execute plan workflow**: Follow the structure in IMPL_PLAN template to:
+   - Fill Technical Context (mark unknowns as "NEEDS CLARIFICATION")
+   - Fill Constitution Check section from constitution
+   - Evaluate gates (ERROR if violations unjustified)
+   - Phase 0: Generate research.md (resolve all NEEDS CLARIFICATION)
+   - Phase 1: Generate data-model.md, contracts/, quickstart.md
+   - Phase 1: Update agent context by running the agent script
+   - Re-evaluate Constitution Check post-design
+
+4. **Stop and report**: Command ends after Phase 2 planning. Report branch, IMPL_PLAN path, and generated artifacts.
+
+## Phases
+
+### Phase 0: Outline & Research
+
+1. **Extract unknowns from Technical Context** above:
+   - For each NEEDS CLARIFICATION → research task
+   - For each dependency → best practices task
+   - For each integration → patterns task
+
+2. **Generate and dispatch research agents**:
+   ```
+   For each unknown in Technical Context:
+     Task: "Research {unknown} for {feature context}"
+   For each technology choice:
+     Task: "Find best practices for {tech} in {domain}"
+   ```
+
+3. **Consolidate findings** in `research.md` using format:
+   - Decision: [what was chosen]
+   - Rationale: [why chosen]
+   - Alternatives considered: [what else evaluated]
+
+**Output**: research.md with all NEEDS CLARIFICATION resolved
+
+### Phase 1: Design & Contracts
+
+**Prerequisites:** `research.md` complete
+
+1. **Extract entities from feature spec** → `data-model.md`:
+   - Entity name, fields, relationships
+   - Validation rules from requirements
+   - State transitions if applicable
+
+2. **Generate API contracts** from functional requirements:
+   - For each user action → endpoint
+   - Use standard REST/GraphQL patterns
+   - Output OpenAPI/GraphQL schema to `/contracts/`
+
+3. **Agent context update**:
+   - Run `.specify/scripts/bash/update-agent-context.sh kilocode`
+   - These scripts detect which AI agent is in use
+   - Update the appropriate agent-specific context file
+   - Add only new technology from current plan
+   - Preserve manual additions between markers
+
+**Output**: data-model.md, /contracts/*, quickstart.md, agent-specific file
+
+## Key rules
+
+- Use absolute paths
+- ERROR on gate failures or unresolved clarifications

+description: Create or update the feature specification from a natural language feature description.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+The text the user typed after `/speckit.specify` in the triggering message **is** the feature description. Assume you always have it available in this conversation even if `$ARGUMENTS` appears literally below. Do not ask the user to repeat it unless they provided an empty command.
+
+Given that feature description, do this:
+
+1. Run the script `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS"` from repo root and parse its JSON output for BRANCH_NAME and SPEC_FILE. All file paths must be absolute.
+  **IMPORTANT** You must only ever run this script once. The JSON is provided in the terminal as output - always refer to it to get the actual content you're looking for. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+2. Load `.specify/templates/spec-template.md` to understand required sections.
+
+3. Follow this execution flow:
+
+    1. Parse user description from Input
+       If empty: ERROR "No feature description provided"
+    2. Extract key concepts from description
+       Identify: actors, actions, data, constraints
+    3. For unclear aspects:
+       - Make informed guesses based on context and industry standards
+       - Only mark with [NEEDS CLARIFICATION: specific question] if:
+         - The choice significantly impacts feature scope or user experience
+         - Multiple reasonable interpretations exist with different implications
+         - No reasonable default exists
+       - **LIMIT: Maximum 3 [NEEDS CLARIFICATION] markers total**
+       - Prioritize clarifications by impact: scope > security/privacy > user experience > technical details
+    4. Fill User Scenarios & Testing section
+       If no clear user flow: ERROR "Cannot determine user scenarios"
+    5. Generate Functional Requirements
+       Each requirement must be testable
+       Use reasonable defaults for unspecified details (document assumptions in Assumptions section)
+    6. Define Success Criteria
+       Create measurable, technology-agnostic outcomes
+       Include both quantitative metrics (time, performance, volume) and qualitative measures (user satisfaction, task completion)
+       Each criterion must be verifiable without implementation details
+    7. Identify Key Entities (if data involved)
+    8. Return: SUCCESS (spec ready for planning)
+
+4. Write the specification to SPEC_FILE using the template structure, replacing placeholders with concrete details derived from the feature description (arguments) while preserving section order and headings.
+
+5. **Specification Quality Validation**: After writing the initial spec, validate it against quality criteria:
+
+   a. **Create Spec Quality Checklist**: Generate a checklist file at `FEATURE_DIR/checklists/requirements.md` using the checklist template structure with these validation items:
+   
+      ```markdown
+      # Specification Quality Checklist: [FEATURE NAME]
+      
+      **Purpose**: Validate specification completeness and quality before proceeding to planning
+      **Created**: [DATE]
+      **Feature**: [Link to spec.md]
+      
+      ## Content Quality
+      
+      - [ ] No implementation details (languages, frameworks, APIs)
+      - [ ] Focused on user value and business needs
+      - [ ] Written for non-technical stakeholders
+      - [ ] All mandatory sections completed
+      
+      ## Requirement Completeness
+      
+      - [ ] No [NEEDS CLARIFICATION] markers remain
+      - [ ] Requirements are testable and unambiguous
+      - [ ] Success criteria are measurable
+      - [ ] Success criteria are technology-agnostic (no implementation details)
+      - [ ] All acceptance scenarios are defined
+      - [ ] Edge cases are identified
+      - [ ] Scope is clearly bounded
+      - [ ] Dependencies and assumptions identified
+      
+      ## Feature Readiness
+      
+      - [ ] All functional requirements have clear acceptance criteria
+      - [ ] User scenarios cover primary flows
+      - [ ] Feature meets measurable outcomes defined in Success Criteria
+      - [ ] No implementation details leak into specification
+      
+      ## Notes
+      
+      - Items marked incomplete require spec updates before `/speckit.clarify` or `/speckit.plan`
+      ```
+   
+   b. **Run Validation Check**: Review the spec against each checklist item:
+      - For each item, determine if it passes or fails
+      - Document specific issues found (quote relevant spec sections)
+   
+   c. **Handle Validation Results**:
+      
+      - **If all items pass**: Mark checklist complete and proceed to step 6
+      
+      - **If items fail (excluding [NEEDS CLARIFICATION])**:
+        1. List the failing items and specific issues
+        2. Update the spec to address each issue
+        3. Re-run validation until all items pass (max 3 iterations)
+        4. If still failing after 3 iterations, document remaining issues in checklist notes and warn user
+      
+      - **If [NEEDS CLARIFICATION] markers remain**:
+        1. Extract all [NEEDS CLARIFICATION: ...] markers from the spec
+        2. **LIMIT CHECK**: If more than 3 markers exist, keep only the 3 most critical (by scope/security/UX impact) and make informed guesses for the rest
+        3. For each clarification needed (max 3), present options to user in this format:
+        
+           ```markdown
+           ## Question [N]: [Topic]
+           
+           **Context**: [Quote relevant spec section]
+           
+           **What we need to know**: [Specific question from NEEDS CLARIFICATION marker]
+           
+           **Suggested Answers**:
+           
+           | Option | Answer | Implications |
+           |--------|--------|--------------|
+           | A      | [First suggested answer] | [What this means for the feature] |
+           | B      | [Second suggested answer] | [What this means for the feature] |
+           | C      | [Third suggested answer] | [What this means for the feature] |
+           | Custom | Provide your own answer | [Explain how to provide custom input] |
+           
+           **Your choice**: _[Wait for user response]_
+           ```
+        
+        4. **CRITICAL - Table Formatting**: Ensure markdown tables are properly formatted:
+           - Use consistent spacing with pipes aligned
+           - Each cell should have spaces around content: `| Content |` not `|Content|`
+           - Header separator must have at least 3 dashes: `|--------|`
+           - Test that the table renders correctly in markdown preview
+        5. Number questions sequentially (Q1, Q2, Q3 - max 3 total)
+        6. Present all questions together before waiting for responses
+        7. Wait for user to respond with their choices for all questions (e.g., "Q1: A, Q2: Custom - [details], Q3: B")
+        8. Update the spec by replacing each [NEEDS CLARIFICATION] marker with the user's selected or provided answer
+        9. Re-run validation after all clarifications are resolved
+   
+   d. **Update Checklist**: After each validation iteration, update the checklist file with current pass/fail status
+
+6. Report completion with branch name, spec file path, checklist results, and readiness for the next phase (`/speckit.clarify` or `/speckit.plan`).
+
+**NOTE:** The script creates and checks out the new branch and initializes the spec file before writing.
+
+## General Guidelines
+
+## Quick Guidelines
+
+- Focus on **WHAT** users need and **WHY**.
+- Avoid HOW to implement (no tech stack, APIs, code structure).
+- Written for business stakeholders, not developers.
+- DO NOT create any checklists that are embedded in the spec. That will be a separate command.
+
+### Section Requirements
+
+- **Mandatory sections**: Must be completed for every feature
+- **Optional sections**: Include only when relevant to the feature
+- When a section doesn't apply, remove it entirely (don't leave as "N/A")
+
+### For AI Generation
+
+When creating this spec from a user prompt:
+
+1. **Make informed guesses**: Use context, industry standards, and common patterns to fill gaps
+2. **Document assumptions**: Record reasonable defaults in the Assumptions section
+3. **Limit clarifications**: Maximum 3 [NEEDS CLARIFICATION] markers - use only for critical decisions that:
+   - Significantly impact feature scope or user experience
+   - Have multiple reasonable interpretations with different implications
+   - Lack any reasonable default
+4. **Prioritize clarifications**: scope > security/privacy > user experience > technical details
+5. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
+6. **Common areas needing clarification** (only if no reasonable default exists):
+   - Feature scope and boundaries (include/exclude specific use cases)
+   - User types and permissions (if multiple conflicting interpretations possible)
+   - Security/compliance requirements (when legally/financially significant)
+   
+**Examples of reasonable defaults** (don't ask about these):
+
+- Data retention: Industry-standard practices for the domain
+- Performance targets: Standard web/mobile app expectations unless specified
+- Error handling: User-friendly messages with appropriate fallbacks
+- Authentication method: Standard session-based or OAuth2 for web apps
+- Integration patterns: RESTful APIs unless specified otherwise
+
+### Success Criteria Guidelines
+
+Success criteria must be:
+
+1. **Measurable**: Include specific metrics (time, percentage, count, rate)
+2. **Technology-agnostic**: No mention of frameworks, languages, databases, or tools
+3. **User-focused**: Describe outcomes from user/business perspective, not system internals
+4. **Verifiable**: Can be tested/validated without knowing implementation details
+
+**Good examples**:
+
+- "Users can complete checkout in under 3 minutes"
+- "System supports 10,000 concurrent users"
+- "95% of searches return results in under 1 second"
+- "Task completion rate improves by 40%"
+
+**Bad examples** (implementation-focused):
+
+- "API response time is under 200ms" (too technical, use "Users see results instantly")
+- "Database can handle 1000 TPS" (implementation detail, use user-facing metric)
+- "React components render efficiently" (framework-specific)
+- "Redis cache hit rate above 80%" (technology-specific)

+description: Generate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts.
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Outline
+
+1. **Setup**: Run `.specify/scripts/bash/check-prerequisites.sh --json` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
+
+2. **Load design documents**: Read from FEATURE_DIR:
+   - **Required**: plan.md (tech stack, libraries, structure), spec.md (user stories with priorities)
+   - **Optional**: data-model.md (entities), contracts/ (API endpoints), research.md (decisions), quickstart.md (test scenarios)
+   - Note: Not all projects have all documents. Generate tasks based on what's available.
+
+3. **Execute task generation workflow** (follow the template structure):
+   - Load plan.md and extract tech stack, libraries, project structure
+   - **Load spec.md and extract user stories with their priorities (P1, P2, P3, etc.)**
+   - If data-model.md exists: Extract entities → map to user stories
+   - If contracts/ exists: Each file → map endpoints to user stories
+   - If research.md exists: Extract decisions → generate setup tasks
+   - **Generate tasks ORGANIZED BY USER STORY**:
+     - Setup tasks (shared infrastructure needed by all stories)
+     - **Foundational tasks (prerequisites that must complete before ANY user story can start)**
+     - For each user story (in priority order P1, P2, P3...):
+       - Group all tasks needed to complete JUST that story
+       - Include models, services, endpoints, UI components specific to that story
+       - Mark which tasks are [P] parallelizable
+       - If tests requested: Include tests specific to that story
+     - Polish/Integration tasks (cross-cutting concerns)
+   - **Tests are OPTIONAL**: Only generate test tasks if explicitly requested in the feature spec or user asks for TDD approach
+   - Apply task rules:
+     - Different files = mark [P] for parallel
+     - Same file = sequential (no [P])
+     - If tests requested: Tests before implementation (TDD order)
+   - Number tasks sequentially (T001, T002...)
+   - Generate dependency graph showing user story completion order
+   - Create parallel execution examples per user story
+   - Validate task completeness (each user story has all needed tasks, independently testable)
+
+4. **Generate tasks.md**: Use `.specify.specify/templates/tasks-template.md` as structure, fill with:
+   - Correct feature name from plan.md
+   - Phase 1: Setup tasks (project initialization)
+   - Phase 2: Foundational tasks (blocking prerequisites for all user stories)
+   - Phase 3+: One phase per user story (in priority order from spec.md)
+     - Each phase includes: story goal, independent test criteria, tests (if requested), implementation tasks
+     - Clear [Story] labels (US1, US2, US3...) for each task
+     - [P] markers for parallelizable tasks within each story
+     - Checkpoint markers after each story phase
+   - Final Phase: Polish & cross-cutting concerns
+   - Numbered tasks (T001, T002...) in execution order
+   - Clear file paths for each task
+   - Dependencies section showing story completion order
+   - Parallel execution examples per story
+   - Implementation strategy section (MVP first, incremental delivery)
+
+5. **Report**: Output path to generated tasks.md and summary:
+   - Total task count
+   - Task count per user story
+   - Parallel opportunities identified
+   - Independent test criteria for each story
+   - Suggested MVP scope (typically just User Story 1)
+
+Context for task generation: $ARGUMENTS
+
+The tasks.md should be immediately executable - each task must be specific enough that an LLM can complete it without additional context.
+
+## Task Generation Rules
+
+**IMPORTANT**: Tests are optional. Only generate test tasks if the user explicitly requested testing or TDD approach in the feature specification.
+
+**CRITICAL**: Tasks MUST be organized by user story to enable independent implementation and testing.
+
+1. **From User Stories (spec.md)** - PRIMARY ORGANIZATION:
+   - Each user story (P1, P2, P3...) gets its own phase
+   - Map all related components to their story:
+     - Models needed for that story
+     - Services needed for that story
+     - Endpoints/UI needed for that story
+     - If tests requested: Tests specific to that story
+   - Mark story dependencies (most stories should be independent)
+   
+2. **From Contracts**:
+   - Map each contract/endpoint → to the user story it serves
+   - If tests requested: Each contract → contract test task [P] before implementation in that story's phase
+   
+3. **From Data Model**:
+   - Map each entity → to the user story(ies) that need it
+   - If entity serves multiple stories: Put in earliest story or Setup phase
+   - Relationships → service layer tasks in appropriate story phase
+   
+4. **From Setup/Infrastructure**:
+   - Shared infrastructure → Setup phase (Phase 1)
+   - Foundational/blocking tasks → Foundational phase (Phase 2)
+     - Examples: Database schema setup, authentication framework, core libraries, base configurations
+     - These MUST complete before any user story can be implemented
+   - Story-specific setup → within that story's phase
+
+5. **Ordering**:
+   - Phase 1: Setup (project initialization)
+   - Phase 2: Foundational (blocking prerequisites - must complete before user stories)
+   - Phase 3+: User Stories in priority order (P1, P2, P3...)
+     - Within each story: Tests (if requested) → Models → Services → Endpoints → Integration
+   - Final Phase: Polish & Cross-Cutting Concerns
+   - Each user story phase should be a complete, independently testable increment

+All projects MUST use Python virtual environments.
+Virtual environments MUST be named `.venv` in the project root.
+Dependencies MUST be pinned in `requirements.txt`.
+Development dependencies MUST be separate from production dependencies.
 
-### [PRINCIPLE_3_NAME]
-<!-- Example: III. Test-First (NON-NEGOTIABLE) -->

+# fit-track-central-db-api-client
+A client library for accessing FitTrack CentralDB API
+
+## Usage
+First, create a client:
+
+```python
+from fit_track_central_db_api_client import Client
+
+client = Client(base_url="https://api.example.com")
+```
+
+If the endpoints you're going to hit require authentication, use `AuthenticatedClient` instead:
+
+```python
+from fit_track_central_db_api_client import AuthenticatedClient
+
+client = AuthenticatedClient(base_url="https://api.example.com", token="SuperSecretToken")
+```
+
+Now call your endpoint and use your models:
+
+```python
+from fit_track_central_db_api_client.models import MyDataModel
+from fit_track_central_db_api_client.api.my_tag import get_my_data_model
+from fit_track_central_db_api_client.types import Response
+
+with client as client:
+    my_data: MyDataModel = get_my_data_model.sync(client=client)
+    # or if you need more info (e.g. status_code)
+    response: Response[MyDataModel] = get_my_data_model.sync_detailed(client=client)
+```
+
+Or do the same thing with an async version:
+
+```python
+from fit_track_central_db_api_client.models import MyDataModel
+from fit_track_central_db_api_client.api.my_tag import get_my_data_model
+from fit_track_central_db_api_client.types import Response
+
+async with client as client:
+    my_data: MyDataModel = await get_my_data_model.asyncio(client=client)
+    response: Response[MyDataModel] = await get_my_data_model.asyncio_detailed(client=client)
+```
+
+By default, when you're calling an HTTPS API it will attempt to verify that SSL is working correctly. Using certificate verification is highly recommended most of the time, but sometimes you may need to authenticate to a server (especially an internal server) using a custom certificate bundle.
+
+```python
+client = AuthenticatedClient(
+    base_url="https://internal_api.example.com", 
+    token="SuperSecretToken",
+    verify_ssl="/path/to/certificate_bundle.pem",
+)
+```
+
+You can also disable certificate validation altogether, but beware that **this is a security risk**.
+
+```python
+client = AuthenticatedClient(
+    base_url="https://internal_api.example.com", 
+    token="SuperSecretToken", 
+    verify_ssl=False
+)
+```
+
+Things to know:
+1. Every path/method combo becomes a Python module with four functions:
+    1. `sync`: Blocking request that returns parsed data (if successful) or `None`
+    1. `sync_detailed`: Blocking request that always returns a `Request`, optionally with `parsed` set if the request was successful.
+    1. `asyncio`: Like `sync` but async instead of blocking
+    1. `asyncio_detailed`: Like `sync_detailed` but async instead of blocking
+
+1. All path/query params, and bodies become method arguments.
+1. If your endpoint had any tags on it, the first tag will be used as a module name for the function (my_tag above)
+1. Any endpoint which did not have a tag will be in `fit_track_central_db_api_client.api.default`
+
+## Advanced customizations
+
+There are more settings on the generated `Client` class which let you control more runtime behavior, check out the docstring on that class for more info. You can also customize the underlying `httpx.Client` or `httpx.AsyncClient` (depending on your use-case):
+
+```python
+from fit_track_central_db_api_client import Client
+
+def log_request(request):
+    print(f"Request event hook: {request.method} {request.url} - Waiting for response")
+
+def log_response(response):
+    request = response.request
+    print(f"Response event hook: {request.method} {request.url} - Status {response.status_code}")
+
+client = Client(
+    base_url="https://api.example.com",
+    httpx_args={"event_hooks": {"request": [log_request], "response": [log_response]}},
+)
+
+# Or get the underlying httpx client to modify directly with client.get_httpx_client() or client.get_async_httpx_client()
+```
+
+You can even set the httpx client directly, but beware that this will override any existing settings (e.g., base_url):
+
+```python
+import httpx
+from fit_track_central_db_api_client import Client
+
+client = Client(
+    base_url="https://api.example.com",
+)
+# Note that base_url needs to be re-set, as would any shared cookies, headers, etc.
+client.set_httpx_client(httpx.Client(base_url="https://api.example.com", proxies="http://localhost:8030"))
+```
+
+## Building / publishing this package
+This project uses [Poetry](https://python-poetry.org/) to manage dependencies  and packaging.  Here are the basics:
+1. Update the metadata in pyproject.toml (e.g. authors, version)
+1. If you're using a private repository, configure it with Poetry
+    1. `poetry config repositories.<your-repository-name> <url-to-your-repository>`
+    1. `poetry config http-basic.<your-repository-name> <username> <password>`
+1. Publish the client with `poetry publish --build -r <your-repository-name>` or, if for public PyPI, just `poetry publish --build`
+
+If you want to install this client into another project without publishing it (e.g. for development) then:
+1. If that project **is using Poetry**, you can simply do `poetry add <path-to-this-client>` from that project
+1. If that project is not using Poetry:
+    1. Build a wheel with `poetry build -f wheel`
+    1. Install that wheel from the other project `pip install <path-to-wheel>`

+# GarminSync Development Workflow
+
+This document describes the new development workflow for GarminSync using UV and justfile.
+
+## Dependency Management
+
+We've switched from pip/requirements.txt to UV for faster dependency installation. The dependency specification is in `pyproject.toml`.
+
+### Key Commands:
+
+```bash
+# Install dependencies with UV
+just run_build
+
+# Create and activate virtual environment
+uv venv .venv
+source .venv/bin/activate
+
+# Update dependencies
+uv pip install -r pyproject.toml
+```
+
+## Tooling Integration
+
+### justfile Commands
+
+Our workflow is managed through a justfile with these commands:
+
+```bash
+just run_dev      # Run server in development mode with live reload
+just run_test     # Run validation tests
+just run_lint     # Run linter (Ruff)
+just run_format   # Run formatter (Black)
+just run_migrate  # Run database migrations
+```
+
+### Pre-commit Hooks
+
+We've added pre-commit hooks for automatic formatting and linting:
+
+```bash
+# Install pre-commit hooks
+pre-commit install
+
+# Run pre-commit on all files
+pre-commit run --all-files
+```
+
+The hooks enforce:
+- Code formatting with Black
+- Linting with Ruff
+- Type checking with mypy

+# GPX File Support in GarminSync
+
+GarminSync now supports processing GPX files with accurate distance calculation using the Haversine formula.
+
+## Features
+
+- Parses GPX 1.1 files with extended Garmin TrackPoint extensions
+- Calculates total distance using Haversine formula
+- Extracts elevation data including gain/loss
+- Processes heart rate and cadence data
+- Calculates activity duration
+
+## Supported Metrics
+
+| Metric | Description | Data Source |
+|--------|-------------|-------------|
+| Distance | Total activity distance | Calculated from GPS coordinates |
+| Duration | Activity duration | Start/end timestamps |
+| Elevation | Min, max, gain, loss | ele tags in track points |
+| Heart Rate | Max and average | gpx:hr extension |
+| Cadence | Average cadence | gpx:cad extension |
+
+## Implementation Details
+
+The GPX parser:
+1. Uses XML parsing to extract track points
+2. Calculates distance between points using Haversine formula
+3. Processes elevation data to determine gain/loss
+4. Handles time zone conversions for timestamps
+5. Gracefully handles missing data points
+
+For more details, see the [gpx_parser.py](garminsync/parsers/gpx_parser.py) file.

+# GarminSync
+
+GarminSync is a powerful Python application that automatically downloads `.fit` files for all your activities from Garmin Connect. It provides both a command-line interface for manual operations and a daemon mode for automatic background synchronization with a web-based dashboard for monitoring and configuration.
+
+## Features
+
+- **CLI Interface**: List and download activities with flexible filtering options
+- **Daemon Mode**: Automatic background synchronization with configurable schedules
+- **Web Dashboard**: Real-time monitoring and configuration through a web interface
+- **Offline Mode**: Work with cached data without internet connectivity
+- **Database Tracking**: SQLite database to track download status and file locations
+- **Rate Limiting**: Respects Garmin Connect's servers with built-in rate limiting
+- **GPX Support**: Parse and process GPX files for extended metrics
+- **Modern Development Workflow**: UV for dependency management and justfile for commands
+
+## Technology Stack
+
+- **Backend**: Python 3.10 with SQLAlchemy ORM
+- **CLI Framework**: Typer for command-line interface
+- **Web Framework**: FastAPI with Jinja2 templates
+- **Database**: SQLite for local data storage
+- **Scheduling**: APScheduler for daemon mode scheduling
+- **Containerization**: Docker support for easy deployment
+
+## Installation
+
+### Prerequisites
+
+- Docker (recommended) OR Python 3.10+
+- Garmin Connect account credentials
+
+### Using Docker (Recommended)
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/sstent/GarminSync.git
+   cd GarminSync
+   ```
+
+2. Create a `.env` file with your Garmin credentials:
+   ```bash
+   echo "GARMIN_EMAIL=your_email@example.com" > .env
+   echo "GARMIN_PASSWORD=your_password" >> .env
+   ```
+
+3. Build the Docker image:
+   ```bash
+   docker build -t garminsync .
+   ```
+
+## Development Workflow
+
+We've implemented a modern development workflow using:
+- UV for fast dependency management
+- justfile commands for common tasks
+- Pre-commit hooks for automatic formatting and linting
+
+See [DEVELOPMENT_WORKFLOW.md](DEVELOPMENT_WORKFLOW.md) for details.
+
+## GPX File Support
+
+GarminSync now supports processing GPX files with accurate metrics extraction including:
+
+- Distance calculation using Haversine formula
+- Elevation gain/loss metrics
+- Heart rate and cadence data
+- Activity duration calculation
+
+See [GPX_SUPPORT.md](GPX_SUPPORT.md) for implementation details.
+
+### Using Python Directly
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/sstent/GarminSync.git
+   cd GarminSync
+   ```
+
+2. Create a virtual environment and activate it:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+   ```
+
+3. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+4. Create a `.env` file with your Garmin credentials:
+   ```bash
+   echo "GARMIN_EMAIL=your_email@example.com" > .env
+   echo "GARMIN_PASSWORD=your_password" >> .env
+   ```
+
+## Usage
+
+### CLI Commands
+
+List all activities:
+```bash
+# Using Docker
+docker run -it --env-file .env -v $(pwd)/data:/app/data garminsync list --all
+
+# Using Python directly
+python -m garminsync.cli list --all
+```
+
+List missing activities:
+```bash
+# Using Docker
+docker run -it --env-file .env -v $(pwd)/data:/app/data garminsync list --missing
+
+# Using Python directly
+python -m garminsync.cli list --missing
+```
+
+List downloaded activities:
+```bash
+# Using Docker
+docker run -it --env-file .env -v $(pwd)/data:/app/data garminsync list --downloaded
+
+# Using Python directly
+python -m garminsync.cli list --downloaded
+```
+
+Download missing activities:
+```bash
+# Using Docker
+docker run -it --env-file .env -v $(pwd)/data:/app/data garminsync download --missing
+
+# Using Python directly
+python -m garminsync.cli download --missing
+```
+
+Work offline (without syncing with Garmin Connect):
+```bash
+# Using Docker
+docker run -it --env-file .env -v $(pwd)/data:/app/data garminsync list --missing --offline
+
+# Using Python directly
+python -m garminsync.cli list --missing --offline
+```
+
+### Daemon Mode
+
+Start the daemon with web UI:
+```bash
+# Using Docker (expose port 8080 for web UI)
+docker run -it --env-file .env -v $(pwd)/data:/app/data -p 8080:8080 garminsync daemon --start
+
+# Using Python directly
+python -m garminsync.cli daemon --start
+```
+
+Access the web dashboard at `http://localhost:8080`
+
+### Web Interface
+
+The web interface provides real-time monitoring and configuration capabilities:
+
+1. **Dashboard**: View activity statistics, daemon status, and recent logs
+2. **Activities**: Browse all activities with detailed information in a sortable table
+3. **Logs**: Filter and browse synchronization logs with pagination
+4. **Configuration**: Manage daemon settings and scheduling
+
+## Configuration
+
+### Environment Variables
+
+Create a `.env` file in the project root with your Garmin Connect credentials:
+
+```env
+GARMIN_EMAIL=your_email@example.com
+GARMIN_PASSWORD=your_password
+```
+
+### Daemon Scheduling
+
+The daemon uses cron-style scheduling. Configure the schedule through the web UI or by modifying the database directly. Default schedule is every 6 hours (`0 */6 * * *`).
+
+### Data Storage
+
+Downloaded `.fit` files and the SQLite database are stored in the `data/` directory by default. When using Docker, this directory is mounted as a volume to persist data between container runs.
+
+## Web API Endpoints
+
+The web interface provides RESTful API endpoints for programmatic access:
+
+- `GET /api/status` - Get daemon status and recent logs
+- `GET /api/activities/stats` - Get activity statistics
+- `GET /api/activities` - Get paginated activities with filtering
+- `GET /api/activities/{activity_id}` - Get detailed activity information
+- `GET /api/dashboard/stats` - Get comprehensive dashboard statistics
+- `GET /api/logs` - Get filtered and paginated logs
+- `POST /api/sync/trigger` - Manually trigger synchronization
+- `POST /api/schedule` - Update daemon schedule configuration
+- `POST /api/daemon/start` - Start the daemon
+- `POST /api/daemon/stop` - Stop the daemon
+- `DELETE /api/logs` - Clear all logs

+# GarminSync Improvement Plan - Junior Developer Guide
+
+## Overview
+This plan focuses on keeping things simple while making meaningful improvements. We'll avoid complex async patterns and stick to a single-container approach.
+
+---
+
+## Phase 1: Fix Blocking Issues & Add GPX Support (Week 1-2)
+
+### Problem: Sync blocks the web UI
+**Current Issue:** When sync runs, users can't use the web interface.
+
+### Solution: Simple Threading
+Instead of complex async, use Python's threading module:
+
+```python
+# garminsync/daemon.py - Update sync_and_download method
+import threading
+from datetime import datetime
+
+class GarminSyncDaemon:
+    def __init__(self):
+        self.scheduler = BackgroundScheduler()
+        self.running = False
+        self.web_server = None
+        self.sync_lock = threading.Lock()  # Prevent multiple syncs
+        self.sync_in_progress = False
+
+    def sync_and_download(self):
+        """Non-blocking sync job"""
+        # Check if sync is already running
+        if not self.sync_lock.acquire(blocking=False):
+            logger.info("Sync already in progress, skipping...")
+            return
+            
+        try:
+            self.sync_in_progress = True
+            self._do_sync_work()
+        finally:
+            self.sync_in_progress = False
+            self.sync_lock.release()
+    
+    def _do_sync_work(self):
+        """The actual sync logic (moved from sync_and_download)"""
+        # ... existing sync code here ...
+```
+
+### Add GPX Parser
+Create a new parser for GPX files:
+
+```python
+# garminsync/parsers/gpx_parser.py
+import xml.etree.ElementTree as ET
+from datetime import datetime
+
+def parse_gpx_file(file_path):
+    """Parse GPX file to extract activity metrics"""
+    try:
+        tree = ET.parse(file_path)
+        root = tree.getroot()
+        
+        # GPX uses different namespace
+        ns = {'gpx': 'http://www.topografix.com/GPX/1/1'}

+        # Calculate basic metrics
+        start_time = None
+        end_time = None
+        total_distance = 0.0
+        elevations = []
+        
+        prev_point = None
+        for point in track_points:

+            
+            # Get elevation
+            ele_elem = point.find('gpx:ele', ns)
+            if ele_elem is not None:
+                elevations.append(float(ele_elem.text))
+            
+            # Calculate distance
+            if prev_point is not None:

+                lat2, lon2 = float(point.get('lat')), float(point.get('lon'))
+                total_distance += calculate_distance(lat1, lon1, lat2, lon2)
+            
+            prev_point = point

+                "calories": None
+            }
+        }
+    except Exception as e:
+        print(f"Error parsing GPX file: {e}")
+        return None
+
+def calculate_distance(lat1, lon1, lat2, lon2):
+    """Calculate distance between two GPS points using Haversine formula"""
+    import math
+    
+    # Convert to radians
+    lat1, lon1, lat2, lon2 = map(math.radians, [lat1, lon1, lat2, lon2])
+    
+    # Haversine formula
+    dlat = lat2 - lat1
+    dlon = lon2 - lon1
+    a = math.sin(dlat/2)**2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon/2)**2
+    c = 2 * math.asin(math.sqrt(a))
+    
+    # Earth's radius in meters
+    earth_radius = 6371000
+    return c * earth_radius
+```
+
+### Update Activity Parser
+```python
+# garminsync/activity_parser.py - Add GPX support
+def detect_file_type(file_path):
+    """Detect file format (FIT, XML, GPX, or unknown)"""

+## Phase 2: Better File Storage & Reduce API Calls (Week 3-4)
+
+### Problem: We're calling Garmin API unnecessarily when we have the file
+
+### Solution: Smart Caching Strategy

+## Testing & Deployment Guide
+
+### Simple Testing Strategy
+```python
+# tests/test_basic_functionality.py - Basic tests for junior developers
+import pytest
+import os
+import tempfile
+from pathlib import Path
+
+def test_file_type_detection():
+    """Test that we can detect different file types correctly"""
+    from garminsync.activity_parser import detect_file_type
+    
+    # Create temporary test files
+    with tempfile.NamedTemporaryFile(suffix='.fit', delete=False) as f:
+        # Write FIT file header
+        f.write(b'\x0E\x10\x43\x08.FIT\x00\x00\x00\x00')
+        fit_file = f.name
+    
+    with tempfile.NamedTemporaryFile(suffix='.gpx', delete=False) as f:
+        f.write(b'<?xml version="1.0"?><gpx version="1.1">')
+        gpx_file = f.name
+    
+    try:
+        assert detect_file_type(fit_file) == 'fit'
+        assert detect_file_type(gpx_file) == 'gpx'
+    finally:
+        os.unlink(fit_file)
+        os.unlink(gpx_file)
+
+def test_activity_metrics_parsing():
+    """Test that we can parse activity metrics"""
+    # This would test your parsing functions
+    pass
+
+# Run with: python -m pytest tests/
+```
+
+### Deployment Checklist
+```yaml
+# docker-compose.yml - Updated for new features
+version: '3.8'
+services:
+  garminsync:
+    build: .
+    ports:
+      - "8888:8888"
+    environment:
+      - GARMIN_EMAIL=${GARMIN_EMAIL}
+      - GARMIN_PASSWORD=${GARMIN_PASSWORD}
+      - DATA_DIR=/data
+    volumes:
+      - ./data:/data
+      - ./logs:/app/logs
+    restart: unless-stopped
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:8888/health"]
+      interval: 30s
+      timeout: 10s
+      retries: 3
+```
+
+---
+
+## Summary & Next Steps
+
+### What This Plan Achieves:
+1. **Non-blocking sync** - Users can browse while sync runs
+2. **Multi-format support** - FIT, TCX, GPX files
+3. **Reduced API calls** - File-first approach with smart caching
+4. **Enhanced UI** - Filtering, search, stats, and trends
+5. **Better file management** - Organized storage with deduplication
+6. **Simple architecture** - Single container, threading instead of complex async
+
+### Implementation Tips for Junior Developers:
+- **Start small** - Implement one phase at a time
+- **Test frequently** - Run the app after each major change
+- **Keep backups** - Always backup your database before migrations
+- **Use logging** - Add print statements and logs liberally
+- **Ask for help** - Don't hesitate to ask questions about complex parts
+
+### Estimated Timeline:
+- **Phase 1-2**: 2-4 weeks (core improvements)
+- **Phase 3-4**: 2-4 weeks (UI enhancements) 
+- **Phase 5-6**: 2-4 weeks (advanced features)
+
+Would you like me to elaborate on any specific phase or create detailed code examples for any particular feature?

+# Implementation Improvements Needed
+
+## 1. **Route Handler Completion** - HIGH PRIORITY
+
+### Missing Import in `internal/web/routes.go`:
+```go
+import (
+    "strconv"  // ADD THIS - needed for strconv.Atoi
+    // ... other imports
+)
+```
+
+### Missing Route Connections in `main.go`:
+```go
+// Current setupRoutes function is incomplete - needs:
+func (app *App) setupRoutes(webHandler *web.WebHandler) *http.ServeMux {
+    mux := http.NewServeMux()
+    
+    // Health check
+    mux.HandleFunc("/health", func(w http.ResponseWriter, r *http.Request) {
+        w.WriteHeader(http.StatusOK)
+        w.Write([]byte("OK"))
+    })
+    
+    // Web UI routes
+    mux.HandleFunc("/", webHandler.Index)
+    mux.HandleFunc("/activities", webHandler.ActivityList) 
+    mux.HandleFunc("/activity", webHandler.ActivityDetail)
+    
+    // ADD THESE API ROUTES:
+    mux.HandleFunc("/api/activities", func(w http.ResponseWriter, r *http.Request) {
+        // Implement API endpoint
+    })
+    mux.HandleFunc("/api/stats", func(w http.ResponseWriter, r *http.Request) {
+        stats, _ := app.db.GetStats()
+        w.Header().Set("Content-Type", "application/json")
+        json.NewEncoder(w).Encode(stats)
+    })
+    mux.HandleFunc("/api/sync", func(w http.ResponseWriter, r *http.Request) {
+        if r.Method == "POST" {
+            go app.syncService.Sync(context.Background())
+            w.Header().Set("Content-Type", "application/json")
+            json.NewEncoder(w).Encode(map[string]string{"status": "started"})
+        }
+    })
+    
+    return mux
+}
+```
+
+## 2. **Database Interface Issues** - HIGH PRIORITY
+
+### Fix SQLiteDB Creation in `main.go`:
+```go
+// CURRENT (INCORRECT):
+app.db = database.NewSQLiteDBFromDB(dbConn)
+
+// SHOULD BE:
+sqliteDB, err := database.NewSQLiteDB(dbPath)
+if err != nil {
+    return err
+}
+app.db = sqliteDB
+```
+
+### Fix Return Type Mismatch:
+Your `NewSQLiteDB` returns `*SQLiteDB` but main.go expects `Database` interface.
+
+## 3. **Template Function Issues** - MEDIUM PRIORITY
+
+### Missing Template Functions in `activity_detail.html`:
+```go
+// Add these template functions to web handler:
+func (h *WebHandler) LoadTemplates(templateDir string) error {
+    // ... existing code ...
+    
+    // Add custom functions
+    funcMap := template.FuncMap{
+        "div": func(a, b float64) float64 { return a / b },
+        "formatDuration": func(seconds int) string {
+            hrs := seconds / 3600
+            mins := (seconds % 3600) / 60
+            return fmt.Sprintf("%dh %dm", hrs, mins)
+        },
+        "formatMeters": func(meters float64) string {
+            return fmt.Sprintf("%.0f", meters)
+        },
+    }
+    
+    for _, page := range pages {
+        name := filepath.Base(page)
+        files := append([]string{page}, layouts...)
+        files = append(files, partials...)
+        
+        h.templates[name], err = template.New(name).Funcs(funcMap).ParseFiles(files...)
+        if err != nil {
+            return err
+        }
+    }
+    
+    return nil
+}
+```
+
+## 4. **Parser Implementation** - MEDIUM PRIORITY
+
+### Complete TCX/GPX Parsers:
+The factory references them but they return `nil`. Either:
+- Implement them fully, or
+- Remove references and return proper errors
+
+```go
+// In factory.go, replace:
+func NewTCXParser() Parser { return nil }
+func NewGPXParser() Parser { return nil }
+
+// With:
+func NewTCXParser() Parser { 
+    return &TCXParser{} // Implement basic TCX parser
+}
+func NewGPXParser() Parser { 
+    return &GPXParser{} // Or remove if not needed
+}
+```
+
+## 5. **Sync Service Integration** - MEDIUM PRIORITY
+
+### Missing Sync Service in Main App:
+```go
+// In main.go App struct, add:
+type App struct {
+    db          *database.SQLiteDB
+    cron        *cron.Cron  
+    server      *http.Server
+    garmin      *garmin.Client
+    syncService *sync.SyncService  // ADD THIS
+    shutdown    chan os.Signal
+}
+
+// In init() method:
+app.syncService = sync.NewSyncService(app.garmin, app.db, dataDir)
+```
+
+## 6. **Build Issues** - LOW PRIORITY
+
+### Fix Go Module Issues:
+Your `go.mod` has some unused dependencies and wrong module path:
+
+```go
+// Update go.mod:
+module garminsync  // Remove github.com path if local
+
+go 1.21
+
+require (
+    github.com/gorilla/mux v1.8.0
+    github.com/mattn/go-sqlite3 v1.14.17
+    github.com/robfig/cron/v3 v3.0.1
+    golang.org/x/net v0.12.0
+)
+
+// Remove unused dependencies like:
+// - github.com/tormoder/fit (if not actually used)
+// - Various lint tools (should be in tools.go)
+```
+
+## 7. **Docker Configuration** - LOW PRIORITY
+
+### Health Check Enhancement:
+```dockerfile
+# In Dockerfile, improve health check:
+HEALTHCHECK --interval=30s --timeout=30s --retries=3 \
+    CMD wget --quiet --tries=1 --spider http://localhost:8888/health || exit 1
+
+# Make sure wget is available or use curl:
+RUN apk add --no-cache ca-certificates tzdata wget
+```

+# GarminSync Workflows
+
+## Migration Workflow
+
+### Purpose
+Add new columns to database and populate with activity metrics
+
+### Trigger
+`python cli.py migrate`
+
+### Steps
+1. Add required columns to activities table:
+   - activity_type (TEXT)
+   - duration (INTEGER)
+   - distance (REAL)
+   - max_heart_rate (INTEGER)
+   - avg_power (REAL)
+   - calories (INTEGER)
+2. For each activity:
+   - Parse metrics from local FIT/XML files
+   - Fetch from Garmin API if local files missing
+   - Update database fields
+3. Commit changes
+4. Report migration status
+
+### Error Handling
+- Logs errors per activity
+- Marks unprocessable activities as "Unknown"
+- Continues processing other activities on error
+
+## Sync Workflow
+
+### Purpose
+Keep local database synchronized with Garmin Connect
+
+### Triggers
+- CLI commands (`list`, `download`)
+- Scheduled daemon (every 6 hours by default)
+- Web UI requests
+
+### Core Components
+- `sync_database()`: Syncs activity metadata
+- `download()`: Fetches missing FIT files
+- Daemon: Background scheduler and web UI
+
+### Process Flow
+1. Authenticate with Garmin API
+2. Fetch latest activities
+3. For each activity:
+   - Parse metrics from FIT/XML files
+   - Fetch from Garmin API if local files missing
+   - Update database fields
+4. Download missing activity files
+5. Update sync timestamps
+6. Log operations
+
+### Database Schema
+```mermaid
+erDiagram
+    activities {
+        integer activity_id PK
+        string start_time
+        string activity_type
+        integer duration
+        float distance
+        integer max_heart_rate
+        integer avg_heart_rate
+        float avg_power
+        integer calories
+        string filename
+        boolean downloaded
+        string created_at
+        string last_sync
+    }
+    
+    daemon_config {
+        integer id PK
+        boolean enabled
+        string schedule_cron
+        string last_run
+        string next_run
+        string status
+    }
+    
+    sync_logs {
+        integer id PK
+        string timestamp
+        string operation
+        string status
+        string message
+        integer activities_processed
+        integer activities_downloaded
+    }
+```
+
+### Key Notes
+- Data directory: `data/` (configurable via DATA_DIR)
+- Web UI port: 8080 (default)
+- Downloaded files: `activity_{id}_{timestamp}.fit`
+- Metrics include: heart rate, power, calories, distance

+# Quickstart Guide: GarminSync Service
+
+This guide provides essential steps for setting up and running the GarminSync service.
+
+## 1. Prerequisites
+
+Before you begin, ensure you have the following installed:
+
+*   **Docker and Docker Compose**: The service is containerized using Docker. Ensure Docker Engine and Docker Compose V3 are installed on your system.
+    *   [Install Docker](https://docs.docker.com/get-docker/)
+    *   [Install Docker Compose](https://docs.docker.com/compose/install/)
+*   **Python 3.13+**: While the service runs in Docker, you might need Python for local development tools or scripting.
+    *   [Install Python](https://www.python.org/downloads/)
+*   **Git**: For cloning the repository.
+
+## 2. Environment Setup
+
+### 2.1. Clone the Repository
+
+First, clone the GarminSync service repository:
+
+```bash
+git clone <repository-url>
+cd <repository-name>
+```
+
+### 2.2. Create and Activate a Python Virtual Environment (Optional, for local development)
+
+It's recommended to use a virtual environment for dependency management:
+
+```bash
+python3.13 -m venv .venv
+source .venv/bin/activate
+```
+
+### 2.3. Install Dependencies (Optional, for local development)
+
+If you are developing locally outside of Docker, install the Python dependencies:
+
+```bash
+pip install -r requirements.txt
+pip install -r requirements-dev.txt
+```
+
+## 3. Configuration
+
+The GarminSync service can be configured via YAML files or environment variables.
+
+### 3.1. Default Configuration
+
+The service defaults to listening on port `8001`.
+
+### 3.2. CentralDB Integration
+
+The service requires a running CentralDB instance. By default, it expects CentralDB to be accessible via its API. The `DB_API_SPEC.json` defines the CentralDB API, and the service will attempt to refresh this spec from `http://localhost:8000/openapi.json`.
+
+You will likely need to configure the CentralDB connection details, either in a YAML configuration file or via environment variables. Refer to the project's main `README.md` or `config` directory for specific configuration options.
+
+## 4. Running the Service
+
+The recommended way to run the GarminSync service is using Docker Compose.
+
+### 4.1. Development Environment
+
+To run the service in a development environment:
+
+```bash
+docker compose -f docker-compose.dev.yml up
+```
+
+This command will build the necessary Docker images and start the GarminSync service along with any other services defined in `docker-compose.dev.yml` (e.g., CentralDB, Redis).
+
+### 4.2. Production Environment
+
+To run the service in a production environment (typically in detached mode):
+
+```bash
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### 4.3. Accessing the Service
+
+Once the service is running, it will be accessible at `http://localhost:8001` (or the configured port). You can then interact with its API endpoints.
+
+## 5. Basic Usage
+
+### 5.1. Link Garmin Connect Account
+
+Before syncing data, you need to link your Garmin Connect account:
+
+```bash
+curl -X POST http://localhost:8001/api/garmin/auth/link \
+     -H "Content-Type: application/json" \
+     -H "Authorization: Bearer <your-app-auth-token>" \
+     -d '{
+           "email": "your_garmin_email@example.com",
+           "password": "your_garmin_password"
+         }'
+```
+Replace `<your-app-auth-token>`, `your_garmin_email@example.com`, and `your_garmin_password` with your actual authentication token and Garmin Connect credentials.
+
+**Note on Authentication**: Currently, `<your-app-auth-token>` is a placeholder. Any non-empty string will be accepted as a valid token by the backend's authentication mechanism, which will then return a mock user. Full token management will be implemented in a future update.
+
+### 5.2. Trigger Activity Synchronization
+
+To trigger an activity sync:
+
+```bash
+curl -X POST http://localhost:8001/api/sync/garmin/activities \
+     -H "Content-Type: application/json" \
+     -H "Authorization: Bearer <your-app-auth-token>" \
+     -d '{
+           "start_date": "2024-01-01",
+           "end_date": "2024-01-31"
+         }'
+```
+
+### 5.3. Check Sync Status
+
+To check the status of synchronization processes:
+
+```bash
+curl -X GET http://localhost:8001/api/sync/status \
+     -H "Authorization: Bearer <your-app-auth-token>"
+```
+
+### 5.4. Upload a Workout
+
+To upload a workout (assuming you have a workout defined in CentralDB with ID `[workout_id]`):
+
+```bash
+curl -X POST http://localhost:8001/api/sync/garmin/workouts \
+     -H "Content-Type: application/json" \
+     -H "Authorization: Bearer <your-app-auth-token>" \
+     -d '{
+           "workout_id": "a1b2c3d4-e5f6-7890-1234-567890abcdef"
+         }'
+```
+
+## 6. Next Steps
+
+*   Refer to the full API documentation (available via OpenAPI/Swagger at `/docs` or `/redoc` when the service is running) for all available endpoints and detailed usage.
+*   Explore the `tests/` directory for examples of how to interact with the service.
+*   Consult the `constitution.yaml` for development and code quality standards.

+### Endpoints for initiating Garmin Connect authentication and linking
+
+**Decision**: Authentication with Garmin Connect will utilize the direct email/password method as implemented in the existing `GarminClient` within `GarminAnalyser.md`. This leverages the `garminconnect` library.
+**Rationale**: Adherence to existing project patterns and reuse of proven authentication mechanisms.
+**Alternatives considered**: Implementing full OAuth2 flow was considered but deferred to maintain consistency with existing `GarminAnalyser.md` logic and simplify initial implementation.
+
+### Endpoint for initiating workout uploads to Garmin Connect
+
+**Decision**: Introduce a new API endpoint, `POST /api/sync/garmin/workouts`, which accepts a workout identifier (e.g., `workout_id` from CentralDB) and triggers an asynchronous workout upload to Garmin Connect. The `garminconnect` library will be used for the actual interaction with Garmin's API.
+
+**Rationale**: The "Technical Context" explicitly states the requirement for workout uploads and mentions "Workout" as a key entity stored in CentralDB. Implementing a dedicated API endpoint ensures clear separation of concerns and provides a standardized way for the frontend or other services to initiate this action. Asynchronous processing is crucial for long-running operations like API calls to external services, maintaining responsiveness of the main application. The `garminconnect` library is the logical choice for this integration given its existing use for activity downloads and its purpose as a Garmin API client.
+
+**Alternatives considered**:
+*   **Batch upload endpoint**: While potentially useful, starting with a single workout upload endpoint is simpler and can be scaled to batch operations later if needed.
+*   **Direct database trigger**: Allowing direct database manipulation to trigger uploads would bypass the API layer, leading to less maintainable and less secure architecture. The API endpoint centralizes control and validation.

+# Quickstart Guide for GarminSync Service
+
+This guide provides instructions to quickly set up and run the GarminSync service.
+
+## Prerequisites
+
+*   Python 3.13 or newer
+*   Docker and Docker Compose (version 3.x)
+*   Git
+
+## 1. Clone the Repository
+
+First, clone the project repository to your local machine:
+
+```bash
+git clone https://github.com/your-repo/GarminSync.git
+cd GarminSync
+```
+
+## 2. Set up Python Virtual Environment
+
+It is highly recommended to use a Python virtual environment to manage dependencies.
+
+```bash
+python3.13 -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+## 3. Configure Environment Variables
+
+The service can be configured via environment variables. Create a `.env` file in the project root based on `example.env` (if provided) or set them directly in your shell.
+
+**Essential Environment Variables**:
+
+*   `GARMIN_CONNECT_EMAIL`: Your Garmin Connect account email.
+*   `GARMIN_CONNECT_PASSWORD`: Your Garmin Connect account password. *(Ensure secure handling of this variable)*
+*   `API_PORT`: The port the service will listen on (defaults to `8001`).
+
+Example `.env` content:
+```
+GARMIN_CONNECT_EMAIL="your_email@example.com"
+GARMIN_CONNECT_PASSWORD="your_garmin_password"
+API_PORT=8001
+```
+
+## 4. Run the Service (Development)
+
+You can run the service directly using `uvicorn` or via Docker Compose.
+
+### Option A: Using Uvicorn (for local development)
+
+```bash
+source .venv/bin/activate
+uvicorn src.main:app --host 0.0.0.0 --port ${API_PORT:-8001} --reload
+```
+
+### Option B: Using Docker Compose
+
+For a containerized development environment:
+
+```bash
+docker compose -f docker-compose.dev.yml up --build
+```
+
+## 5. Access the API Documentation
+
+Once the service is running, you can access the interactive API documentation (Swagger UI) at:
+
+`http://localhost:8001/docs` (or your configured `API_PORT`)
+
+## 6. Basic Usage
+
+### Link Garmin Account
+
+To link your Garmin Connect account, send a POST request to `/api/garmin/auth/link`:
+
+```bash
+curl -X POST "http://localhost:8001/api/garmin/auth/link" \
+     -H "Content-Type: application/json" \
+     -d '{
+           "email": "your_email@example.com",
+           "password": "your_garmin_password"
+         }'
+```
+
+### Trigger Activity Sync
+
+To trigger activity synchronization:
+
+```bash
+curl -X POST "http://localhost:8001/api/sync/garmin/activities" \
+     -H "Content-Type: application/json" \
+     -d '{}'
+```
+
+### Trigger Health Metrics Sync
+
+To trigger health metrics synchronization:
+
+```bash
+curl -X POST "http://localhost:8001/api/sync/garmin/health-metrics" \
+     -H "Content-Type: application/json" \
+     -d '{}'
+```
+
+### Upload Workout
+
+To upload a workout (replace `<WORKOUT_ID>` with an actual workout ID from your CentralDB):
+
+```bash
+curl -X POST "http://localhost:8001/api/sync/garmin/workouts" \
+     -H "Content-Type: application/json" \
+     -d '{
+           "workout_id": "<WORKOUT_ID>"
+         }'
+```
+
+### Check Sync Status
+
+To check the status of synchronization jobs:
+
+```bash
+curl "http://localhost:8001/api/sync/status"
+```
+
+---
+
+**Note**: This quickstart assumes a basic setup. Refer to the full documentation for advanced configuration, deployment, and troubleshooting.

+# Feature Specification: IntialSpecV2
+
+**Feature Branch**: `feature/intial-spec-v2`
+**Created**: 2025-10-09
+**Status**: Draft
+**Input**: User description: "Create a detailed feature specification based on the provided context."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Garmin Connect Activity Synchronization (Priority: P1)
+
+As a user, I want to authenticate with Garmin Connect and have my activities (FIT, GPX, TCX files) downloaded and stored in CentralDB so that I can track my fitness data.
+
+**Why this priority**: This is a core function for the GarminSync service, enabling fundamental data collection.
+
+**Independent Test**: Can be fully tested by authenticating with Garmin Connect, triggering an activity sync, and then verifying that activity files are correctly stored in CentralDB.
+
+**Acceptance Scenarios**:
+
+1.  **Given** a user has successfully authenticated with Garmin Connect, **When** they trigger an activity sync via `POST /api/sync/garmin/activities`, **Then** their recent activities are downloaded from Garmin Connect and stored as FIT/GPX/TCX files in CentralDB.
+2.  **Given** a user has authenticated with Garmin Connect, **When** a sync is triggered, **Then** only new or updated activities are downloaded to avoid redundant data.
+
+---
+
+### User Story 2 - Garmin Connect Health Metrics Synchronization (Priority: P2)
+
+As a user, I want my health metrics to be synchronized from Garmin Connect to CentralDB so I can have a comprehensive view of my health data.
+
+**Why this priority**: Important for a holistic view of user health, complementing activity data.
+
+**Independent Test**: Can be fully tested by authenticating with Garmin Connect, triggering a sync, and verifying that health metrics (e.g., heart rate, sleep data) are correctly synchronized and stored in CentralDB.
+
+**Acceptance Scenarios**:
+
+1.  **Given** a user has successfully authenticated with Garmin Connect, **When** they trigger a sync, **Then** their health metrics are synchronized from Garmin Connect to CentralDB.
+
+---
+
+### User Story 3 - Garmin Workout Upload (Priority: P2)
+
+As a user, I want to be able to upload workouts from the application to Garmin Connect.
+
+**Why this priority**: This provides bidirectional sync functionality, enhancing the utility of the service.
+
+**Independent Test**: Can be fully tested by creating a workout in the application, initiating its upload to Garmin Connect, and then verifying that the workout appears correctly on the user's Garmin Connect account.
+
+**Acceptance Scenarios**:
+
+1.  **Given** a user has a workout defined within the application, **When** they initiate the workout upload to Garmin, **Then** the workout is successfully transmitted and appears on their Garmin Connect account.
+
+---
+
+### User Story 4 - Check Sync Status (Priority: P3)
+
+As a user, I want to be able to check the status of my synchronization processes.
+
+**Why this priority**: Provides essential feedback to the user on ongoing and completed operations, improving user experience.
+
+**Independent Test**: Can be fully tested by triggering a synchronization process, then querying the `/api/sync/status` endpoint to verify that it accurately reflects the ongoing or completed status of the sync.
+
+**Acceptance Scenarios**:
+
+1.  **Given** a synchronization process is in progress, **When** the user makes a `GET` request to `/api/sync/status`, **Then** the system returns the current status of the synchronization, including any progress or errors.
+2.  **Given** a synchronization process has completed, **When** the user makes a `GET` request to `/api/sync/status`, **Then** the system returns the final status of the synchronization, including success or failure details.
+
+---
+
+### Edge Cases
+
+-   What happens when the Garmin Connect API is unavailable or returns an error during activity or health metrics synchronization?

+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies - can start immediately
+- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
+- **User Stories (Phase 3+)**: All depend on Foundational phase completion
+  - User stories can then proceed in parallel (if staffed)
+  - Or sequentially in priority order (P1 → P2 → P3)
+- **Polish (Final Phase)**: Depends on all desired user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
+- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - May integrate with US1 but should be independently testable
+- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - May integrate with US1/US2 but should be independently testable
+- **User Story 4 (P3)**: Can start after Foundational (Phase 2) - Depends on SyncJob from US1/US2/US3 to provide status
+
+### Within Each User Story
+
+- Tests (if included) MUST be written and FAIL before implementation
+- Services before endpoints
+- Core implementation before integration
+- Story complete before moving to next priority
+
+### Parallel Opportunities
+
+- All Setup tasks marked [P] can run in parallel
+- All Foundational tasks marked [P] can run in parallel (within Phase 2)
+- Once Foundational phase completes, all user stories can start in parallel (if team capacity allows)
+- All tests for a user story marked [P] can run in parallel
+- Models within a story marked [P] can run in parallel
+- Different user stories can be worked on in parallel by different team members
+
+
+

+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup
+2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
+3. Complete Phase 3: User Story 1
+4. **STOP and VALIDATE**: Test User Story 1 independently
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Complete Setup + Foundational → Foundation ready
+2. Add User Story 1 → Test independently → Deploy/Demo (MVP!)
+3. Add User Story 2 → Test independently → Deploy/Demo
+4. Add User Story 3 → Test independently → Deploy/Demo
+5. Add User Story 4 → Test independently → Deploy/Demo
+6. Each story adds value without breaking previous stories
+
+### Parallel Team Strategy
+
+With multiple developers:
+
+1. Team completes Setup + Foundational together
+2. Once Foundational is done:
+   - Developer A: User Story 1
+   - Developer B: User Story 2
+   - Developer C: User Story 3
+   - Developer D: User Story 4
+3. Stories complete and integrate independently
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story should be independently completable and testable
+- Verify tests fail before implementing
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently
+- Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence
