sync	Post-task synchronization - update document index, generate action log, and refresh feature/component docs after completing a development task.	[-y|--yes] [--dry-run] [--from-manifest <path>] [--task-id <id>] [--commit <hash>] "task summary"	TodoWrite(*), Agent(*), AskUserQuestion(*), Read(*), Grep(*), Glob(*), Bash(*), Edit(*), Write(*), mcp__ace-tool__search_context(*)

Auto Mode

When --yes or -y: Auto-detect changes, auto-update all docs, skip review prompts.

DDD Sync Command (/ddd:sync)

Purpose

After completing a development task, synchronize the document index with actual code changes:

1. Analyze what changed (git diff)
2. Trace which features/requirements/components are affected
3. Update index entries (status, code locations, links)
4. Generate action log entry
5. Refresh feature-map and tech-registry documents

When to Use: sync vs update

Scenario	Use
Task completed, ready to commit	ddd:sync — full post-task reconciliation
Mid-development, quick impact check	ddd:update
Pre-commit validation	ddd:update --check-only
Auto-triggered after ddd:execute	ddd:sync (automatic)
Periodic index refresh during refactoring	ddd:update

Rule of thumb: sync = task boundary (done something), update = development pulse (doing something).

Prerequisite

• doc-index.json must exist
• Git repository with committed or staged changes

Phase 1: Change Detection

1.0 Data Source Selection

IF --from-manifest <path>:
  Load execution-manifest.json
  → files_modified[] provides precise file list + action type + task attribution
  → TASK-*.result.json provides symbol-level changes + convergence results
  → Skip Phase 1.1/1.2 (already classified by execute)
  → Proceed directly to Phase 2 with manifest data
ELSE:
  → Fall through to Phase 1.1 (git-based discovery)

--from-manifest advantages (used automatically by ddd:execute):

• Precise file → task attribution (which task modified which file)
• Symbol-level change tracking (not just file-level)
• Convergence verification results carried forward to action-log
• Survives process interruptions (manifest is persisted to disk)

1.1 Identify Changes (git-based fallback)

# If --commit provided:
git diff --name-only {commit}^..{commit}
git diff --stat {commit}^..{commit}

# If --task-id provided, find related commits:
git log --oneline --grep="task-{id}" | head -10

# Otherwise: changes since last ddd:sync
git diff --name-only HEAD~1..HEAD

1.2 Classify Changes (git-based fallback)

For each changed file, determine:

• Type: added | modified | deleted | renamed
• Category: source | test | config | docs | other
• Symbols affected: parse diff for changed functions/classes (use Gemini if complex)

Phase 2: Impact Tracing

2.1 Match to Index

For each changed file path:

Search doc-index.json.technicalComponents[].codeLocations[].path
→ Find matching component IDs
→ From components, find linked featureIds
→ From features, find linked requirementIds

2.2 Discover New Components

If changed files don't match any existing component:

• Flag as potential new component
• Ask user if it should be registered (or auto-register with -y)

2.3 Build Impact Report

## Impact Summary

### Changed Files (5)
- src/services/auth.ts (modified) → tech-auth-service → feat-auth
- src/models/user.ts (modified) → tech-user-model → feat-auth
- src/routes/login.ts (added) → NEW COMPONENT → feat-auth
- src/tests/auth.test.ts (modified) → [test file, skip]
- package.json (modified) → [config, skip]

### Affected Features
- feat-auth: User Authentication (2 components modified, 1 new)

### Affected Requirements
- REQ-001: Email login (implementation updated)
- REQ-002: JWT token generation (implementation updated)

Phase 3: Update Index

3.0 Dry-Run Gate

If --dry-run is set:

• Execute Phase 3 analysis (determine what would change)
• Display planned modifications as a preview report
• Skip all file writes (Phase 3.1-3.5 and Phase 4)
• Output: "Dry-run complete. Run without --dry-run to apply changes."

3.0.1 Backup Index

Before any modifications, create backup:

• Copy doc-index.json → doc-index.json.bak
• On failure: restore from .bak and report error
• On success: remove .bak

3.1 Update Technical Components

For each affected component in doc-index.json:

• Update codeLocations if file paths or line ranges changed
• Update symbols if new exports were added
• Add new actionIds entry

3.2 Register New Components

For newly discovered components:

• Generate tech-{slug} ID
• Create entry in technicalComponents[]
• Link to appropriate features
• Generate new tech-registry/{slug}.md document

3.3 Update Feature Status

For each affected feature:

• If all requirements now have mapped components → status: "implemented"
• If some requirements still unmapped → status: "in-progress"

3.4 Add Action Entry

{
  "id": "task-{id}",
  "description": "{task summary from user}",
  "type": "feature|bugfix|refactor",
  "status": "completed",
  "affectedFeatures": ["feat-auth"],
  "affectedComponents": ["tech-auth-service", "tech-user-model"],
  "changedFiles": [
    { "path": "src/services/auth.ts", "action": "modified", "task_id": "TASK-001" },
    { "path": "src/models/user.ts", "action": "modified", "task_id": "TASK-001" }
  ],
  "symbolsChanged": ["AuthService.validate", "UserModel.toJSON"],
  "convergenceResults": {
    "passed": 2,
    "total": 2,
    "details": ["Rate limiter middleware exists", "Config accepts per-route limits"]
  },
  "verifyGate": "PASS|WARN|FAIL|skipped",
  "relatedCommit": "{commit hash}",
  "manifestPath": "{execution-manifest.json path | null}",
  "timestamp": "ISO8601"
}

3.5 Update Timestamp

Set doc-index.json.last_updated to current time.

Phase 4: Refresh Documents

4.1 Update Feature Maps

For each affected feature's feature-maps/{slug}.md:

• Update "Change History" table with new action entry
• Update component list if new components were added
• Update status if changed

4.2 Update Tech Registry

For each affected component's tech-registry/{slug}.md:

• Update code locations
• Update symbol list
• Add action to change history

4.3 Update Action Log

Create .workflow/.doc-index/action-logs/{task-id}.md:

---
id: task-{id}
type: feature|bugfix|refactor
status: completed
features: [feat-auth]
components: [tech-auth-service, tech-user-model]
commit: {hash}
timestamp: ISO8601
---

# Task: {summary}

## Changes
| File | Type | Component |
|------|------|-----------|
| src/services/auth.ts | modified | tech-auth-service |

## Impact
- Features affected: feat-auth
- Requirements addressed: REQ-001, REQ-002

## Notes
{any user-provided notes}

4.4 Update Index Documents

• Refresh feature-maps/_index.md table
• Refresh tech-registry/_index.md table
• Append to action-logs/_index.md table

Phase 5: Confirmation (unless -y)

Present update summary to user:

• Files updated in doc-index
• New documents created
• Status changes
• Ask for confirmation before writing

Flags

Flag	Effect
-y, --yes	Auto-confirm all updates
--dry-run	Preview all changes without modifying any files
--from-manifest <path>	Use execution-manifest.json as data source (auto-set by ddd:execute)
--task-id <id>	Associate with specific task ID
--commit <hash>	Analyze specific commit

Integration Points

• Input from: execution-manifest.json (preferred, from ddd:execute) OR Git history (fallback), doc-index.json, /ddd:plan output
• Output to: Updated doc-index.json, feature-maps/, tech-registry/, action-logs/
• Triggers: After completing any development task
• Data source priority: --from-manifest > --commit > --task-id > git diff HEAD~1
