Sync Feature Branch

Commit current work with Beads tracking + smart discovery handling + auto phase transitions.

Workflow

1. Set Beads Context

mcp__plugin_beads_beads__set_context(workspace_root="/path/to/project")

2. Get Current Issue

git branch --show-current
# Extract FEATURE_KEY from feature-<KEY> pattern

Use MCP tool:

currentIssue = mcp__plugin_beads_beads__show(issue_id=<FEATURE_KEY>)

If not found, auto-create as safety net:

mcp__plugin_beads_beads__create(
  title=<FEATURE_KEY>,
  issue_type="feature",
  priority=2,
  description="Auto-created during commit",
  assignee="claude-code"
)

Note: Issue should ideally exist BEFORE coding (Issue-First Development), but this prevents orphaned commits.

3. Analyze Diff for Discoveries

git diff HEAD

Detect discovery patterns:

• Bug fixes: Lines with "fix:", "bug:", error handling additions
• New tasks: TODO comments, "should add", validation additions
• Protected paths: .claude/hooks/, migrations/, workflows/**

Score risk level:

• Auto (silent): <50 lines, P3-P4, non-protected
• Auto (notify): <100 lines, P2, non-protected
• Prompt: >100 lines OR P0-P1 OR protected paths

4. Handle Discoveries (if detected)

If discovery found and risk <= "auto (notify)":

childIssue = mcp__plugin_beads_beads__create(
  title="Bug: <detected-issue>",
  type="bug",  // or "task" based on pattern
  priority=1,   // or 2 based on severity
  deps=[currentIssue.id],  // Creates discovered-from link
  id=currentIssue.id + ".X"  // Auto-assigned child ID
)

Close child issue BEFORE commit:

mcp__plugin_beads_beads__close(childIssue.id, reason="Fixed")

Force flush to JSONL:

bd sync --flush-only

Commit with child Feature-Key:

git add -A
git commit -m "fix: <issue-description>

Closes ${childIssue.id}

Feature-Key: ${childIssue.id}
Parent-Feature: ${currentIssue.id}
Discovery-Type: bug"

If risk = "prompt", ask user before creating issue.

5. Every Commit Check (make ci-lite)

if make ci-lite exists:
  make ci-lite
  if fails: 
    echo "❌ make ci-lite failed (Linting or Backend Tests)"
    ask user: "Fix errors or force commit? (fix/force)"
    if fix: exit 1

5.5. Doc Auto-Link and Impact Analysis

Auto-link docs to Beads (if not already linked):

# Check if docs directory exists
DOC_DIR="docs/${currentIssue.id}"
if [ -d "$DOC_DIR" ]; then
  # Check if already linked
  CURRENT_REF=$(bd show ${currentIssue.id} --json | jq -r '.external_ref // ""')

  if [ -z "$CURRENT_REF" ] || [ "$CURRENT_REF" = "null" ]; then
    # Auto-link
    bd update ${currentIssue.id} --external-ref "docs:${DOC_DIR}/"
    echo "📎 Auto-linked: ${currentIssue.id} ↔ ${DOC_DIR}/"
  fi
fi

Doc impact analysis:

# Run doc router to analyze which docs might need updates
python3 scripts/ci/doc_router.py --base HEAD --head @ --format brief

Show informational message if doc updates recommended:

ℹ️  Doc Impact Detected:
   - backend/services/auth.py → docs/SECURITY/AUTH.md
   - frontend/components/Login.tsx → docs/FRONTEND/COMPONENTS.md

   Consider updating docs before PR (optional)

Why informational:

• Non-blocking (doesn't fail commit)
• User controls timing (can update now or later)
• CI will also check (reminder in PR comments)

6. Commit Changes

If NO discovery (normal commit):

# Get agent identity (uses DX_AGENT_ID if set, fallback to auto-detect)
AGENT_ID="$(~/.agent/skills/scripts/get_agent_identity.sh)"

git add -A
git commit -m "feat: Progress on {FEATURE_KEY}

Feature-Key: {currentIssue.id}
Agent: $AGENT_ID
Role: {current-role}"

Note: Agent: trailer uses DX_AGENT_ID standard (bd-n1rv). See DX_AGENT_ID.md for details.

If discovery handled, commit was already done in step 4.

7. Check for Phase Completion

After commit, check if current issue should close:

currentIssue = mcp__plugin_beads_beads__show(currentIssue.id)

Auto-close criteria:

• Issue has dependents (tasks waiting)
• Work appears complete (no obvious TODOs in recent commits)
• User didn't say "work in progress" or "checkpoint"

If should close:

mcp__plugin_beads_beads__close(
  currentIssue.id,
  reason="Completed in commit <hash>"
)

8. Auto Phase Transition

After closing current issue, find next ready task:

readyTasks = mcp__plugin_beads_beads__ready(priority=1)

// Filter to dependents of parent epic
nextTask = readyTasks.find(task =>
  task.dependencies.includes(currentIssue.id)
)

If next task found:

mcp__plugin_beads_beads__update(
  nextTask.id,
  status="in_progress"
)

9. Confirm to User

If discovery occurred:

✅ Auto-committed {childIssue.id} (bug fix, 15 lines)
✅ {childIssue.id} closed

📍 Resuming {currentIssue.id}: {currentIssue.title}
   Ready to continue main task

If phase transitioned:

✅ Closed {currentIssue.id} (Research complete)
📍 Starting {nextTask.id}: {nextTask.title}
   Next phase in epic workflow

If normal commit:

✅ Committed to feature-{currentIssue.id}
✅ Beads updated

Next: Say 'create PR' to open pull request

Best Practices

• Set context first - Call set_context() at start of skill
• Analyze diff before commit - Detect discoveries automatically
• Use child IDs - Auto-assigned (bd-xyz.1, bd-xyz.2)
• Link discoveries - deps=[parent] creates discovered-from
• Trust automation - Auto-close criteria are conservative
• Phase transitions - Automatic when dependencies exist
• Context restoration - Always show what's next after transitions

Discovery Detection Patterns

Bug fixes detected by:

• Commit message starts with "fix:", "bug:"
• New error handling (try/catch, if err)
• Permission fixes (chmod, access control)
• Schema corrections (JSON format, API contracts)

Tasks detected by:

• TODO/FIXME comments added
• "should add", "need to implement"
• Placeholder code with notes

Auto-close NOT triggered if:

• User says "checkpoint", "work in progress", "WIP"
• Commit message includes "partial", "incomplete"
• Multiple TODOs remain in diff

What This DOESN'T Do

• ❌ Run full test suite (CI handles this)
• ❌ Build containers (CI handles this)
• ❌ Wait for approval (environments validate async)
• ❌ Close issues if user indicates incomplete work

Philosophy: Fast commits + Smart automation + Context preservation
