docs-update（文档更新）

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each phase. For simple tasks, AI MUST ATTENTION ask user whether to skip.

Critical Purpose: Single orchestrator for ALL documentation sync after code changes. Triages impact, then delegates to specialized skills.

Evidence Gate: MANDATORY IMPORTANT MUST ATTENTION — every claim, finding, and recommendation requires file:line proof or traced evidence with confidence percentage (>80% to act, <80% must verify first).

Quick Summary

Goal: Detect which documentation is impacted by code changes and orchestrate updates across all doc types.

Orchestration Model:

git diff → Triage → Phase 1: Project Docs (inline)
                  → Phase 2: /feature-docs (business feature docs)
                  → Phase 3: /tdd-spec (test specifications)
                  → Phase 4: /test-specs-docs (dashboard sync)
                  → Phase 5: Summary Report

Key Rules:

• This skill is a router — it triages, then invokes sub-skills. No duplicating sub-skill logic.
• Each phase checks whether it's needed before invoking — skip phases with no impact.
• Always report what was checked, even if nothing needed updating.
• Pass triage context (changed files, detected modules, impacted sections) to each sub-skill via $ARGUMENTS.

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Phase 0: Triage — Detect Impacted Documentation

Step 0.1: Collect Changed Files

1. Run git diff --name-only HEAD (captures both staged and unstaged changes)
2. If no uncommitted changes, run git diff --name-only HEAD~1 (last commit)
3. If still empty, run git diff --name-only origin/develop...HEAD (branch changes)

Step 0.2: Categorize Changes

Classify each changed file into documentation impact categories:

Step 0.3: Fast Exit Check

If ALL changed files fall into the none category (e.g., only .claude/, .github/, root config files):

• Report: "No documentation impacted by current changes (config/tooling only)."
• Exit early — skip all phases.

Step 0.4: Auto-Detect Affected Modules

Extract unique module names from changed file paths:

Build project-specific mapping by examining:

ls -d src/Services/*/
ls -d docs/business-features/*/

Step 0.5: Check Existing Docs for Each Module

For each detected module:

1. Check if docs/business-features/{Module}/ exists
2. Check if docs/business-features/{Module}/detailed-features/ has feature docs
3. Check if docs/test-specs/{Module}/ exists
4. Record: hasFeatureDocs, hasTestSpecs, hasTestSpecsDashboard

Phase 1: Project Documentation Update (Inline)

When to run: Changed files include src/{Framework}/**, docs/**, or architectural changes.

When to skip: Only service-layer or frontend feature files changed (no architectural impact). Skip and proceed to Phase 2.

Step 1.1: Spawn Scouts (standalone invocation only)

When invoked standalone (not as a workflow step), spawn scouts for broad codebase context:

1. Spawn 2-4 scout-external (preferred) or scout (fallback) via Task tool
2. Target directories that actually exist — adapt to project structure
3. Merge scout results into context summary

When invoked as a workflow step: Skip scouting — use git diff context from Phase 0 directly.

Step 1.2: Update Project Docs

Pass context to docs-manager sub-agent (Agent tool with subagent_type="docs-manager") to update impacted project docs:

• docs/project-reference/project-structure-reference.md: Update if service architecture or cross-service patterns changed
• README.md: Update if project scope or setup changed (keep under 300 lines)

Only update docs that are directly impacted by the changes. Do not regenerate all docs.

Phase 2: Business Feature Documentation — Invoke /feature-docs

When to run: Triage detected modules with hasFeatureDocs = true AND service/frontend files changed.

When to skip: No service-layer or frontend feature files changed. Report: "No business feature docs impacted."

Step 2.1: Determine Create vs Update

Step 2.2: Invoke /feature-docs

Execute the /feature-docs skill with triage context:

/feature-docs Update feature docs for modules: {detected modules}.
Changed files: {list from triage}.
Impacted sections based on change types: {section impact from triage}.
Mode: update (existing docs only, do not create from scratch).

What /feature-docs handles (DO NOT duplicate here):

• 17-section structure enforcement
• Diff analysis → section impact mapping
• Codebase analysis (entities, commands, queries, controllers)
• Update impacted sections with evidence
• Master index update (BUSINESS-FEATURES.md)
• 3-pass verification (evidence audit, domain model, cross-reference)
• CHANGELOG entry
• v3.0 principles (no code details in S1-14, evidence in S15 only)

Step 2.3: Review /feature-docs Output

After /feature-docs completes, verify:

1. Updated sections align with triage's section impact mapping
2. No sections were missed that the triage identified as impacted
3. If gaps found → re-invoke /feature-docs for missed sections

Phase 3: Test Specifications — Invoke /tdd-spec

When to run: ANY new functionality was added (new commands, queries, endpoints, components) OR existing behavior changed.

When to skip: Changes are purely cosmetic (styling, comments, docs-only) with no behavioral impact.

Step 3.1: Determine TC Mode

Based on triage context, determine the appropriate /tdd-spec mode:

Step 3.2: Invoke /tdd-spec

Execute the /tdd-spec skill with triage context:

/tdd-spec Mode: {detected mode}.
Modules: {detected modules}.
Changed files: {list from triage}.
New functionality detected: {new commands/queries/endpoints from diff analysis}.

What /tdd-spec handles (DO NOT duplicate here):

• 5 modes: TDD-first, implement-first, update, sync, from-integration-tests
• TC-{FEATURE}-{NNN} format with decade-based numbering
• Interactive TC review with user (AskUserQuestion)
• Cross-cutting categories: authorization, seed data, performance, data migration
• Phase-mapped coverage (plan phases → TCs)
• Graph context analysis for cross-service impact
• Evidence verification per TC
• Write to feature doc Section 15 (canonical TC registry)

Step 3.3: Review /tdd-spec Output

After /tdd-spec completes, verify:

1. New TCs cover all new functionality identified in triage
2. TC IDs don't collide with existing ones
3. Evidence fields are populated (not template placeholders)

Phase 4: Test Specs Dashboard Sync — Invoke /test-specs-docs

When to run: Phase 3 produced new or updated TCs, OR docs/test-specs/ exists and may be stale.

When to skip: No test specification changes and no docs/test-specs/ directory exists.

Step 4.1: Invoke /test-specs-docs

Execute the /test-specs-docs skill:

/test-specs-docs Sync test specs for modules: {detected modules}.
Direction: forward (feature docs Section 15 → docs/test-specs/ dashboard).
Updated TCs from Phase 3: {list of new/changed TC IDs}.

What /test-specs-docs handles (DO NOT duplicate here):

• Forward sync: feature docs → dashboard
• Reverse sync: dashboard → feature docs (when requested)
• 3-way comparison: feature doc vs test-specs/ vs test code
• PRIORITY-INDEX.md management
• Module dashboard generation
• Integration test cross-reference ([Trait("TestSpec",...)])

Step 4.2: Review Sync Results

After /test-specs-docs completes, verify:

1. All new TCs from Phase 3 appear in dashboard
2. PRIORITY-INDEX.md updated with correct priority tiers
3. No orphaned TCs (in dashboard but not in feature docs)

Phase 5: Summary Report

Always output a summary of what happened:

### Documentation Update Summary

**Triage:** {N} files changed → {categories detected}
**Modules detected:** {module list}

**Phase 1 — Project Docs:**
- {Updated/Skipped}: {reason}

**Phase 2 — Business Feature Docs (/feature-docs):**
- Module {X}: {Updated sections A, B, C / No existing docs / Not impacted}
- Module {Y}: {Updated sections D, E / Skipped: no feature docs}

**Phase 3 — Test Specifications (/tdd-spec):**
- Mode: {mode used}
- New TCs: {list of TC IDs added}
- Updated TCs: {list of TC IDs modified}
- Skipped: {reason if skipped}

**Phase 4 — Dashboard Sync (/test-specs-docs):**
- {Synced N TCs to dashboard / Skipped: no dashboard exists}
- Discrepancies: {any 3-way comparison issues}

**Recommendations:**
- {Any new docs that should be created}
- {Any stale docs flagged but not auto-fixed}
- {Any TCs flagged as Untested}

Next Steps

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS after completing this skill, you MUST ATTENTION use AskUserQuestion to present these options. Do NOT skip because the task seems "simple" or "obvious" — the user decides:

• "/watzup (Recommended)" — Wrap up session and check for remaining doc staleness
• "/workflow-review-changes" — Review all changes before commit
• "Skip, continue manually" — user decides

Closing Reminders

MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting. MANDATORY IMPORTANT MUST ATTENTION validate decisions with user via AskUserQuestion — never auto-decide. MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality.
