<quick_start> <auto_commit_workflow> Automatic commit generation when changes detected:

Detect uncommitted changes: Run git status --porcelain
Classify change type: Phase completion, task completion, or file modification
Generate commit message: Use Conventional Commits format based on context
Validate safety: Check branch, merge conflicts, commit message format
Execute commit: Stage files and commit with generated message
Provide feedback: Show commit hash and rollback command

Example:

Context: Task T001 completed

❌ UNCOMMITTED CHANGES DETECTED
  Modified: api/models/message.py
  Created: api/tests/test_message.py

✅ AUTO-COMMITTING with generated message:
  feat(green): T001 implement Message model to pass test

  Implementation: SQLAlchemy model with validation
  Tests: 26/26 passing
  Coverage: 93% (+1%)

✅ COMMITTED: abc123f
  Rollback: git revert abc123f

</auto_commit_workflow>

<trigger_patterns> Auto-invoke when detecting:

Phase completion markers:

"Phase N complete"
"/specify complete", "/plan complete", "/tasks complete"
"analysis complete", "optimization complete"
Phase command finishing

Task completion markers:

"T### complete", "task ### done"
"task-tracker mark-done" command
"mark task complete"

Change detection:

git status --porcelain returns non-empty
Files created/modified/deleted
Working tree dirty before phase transition </trigger_patterns>

<commit_message_generation> Conventional Commits format:

<type>(<scope>): <subject>

[optional body]

[optional footer]

Auto-detection logic:

Context	Type	Scope	Subject Template
Phase 0	docs	spec	create specification for {feature}
Phase 0.5	docs	clarify	resolve {n} clarifications for {feature}
Phase 1	docs	plan	create implementation plan for {feature}
Phase 2	docs	tasks	create task breakdown for {feature} ({n} tasks)
Phase 3	docs	analyze	create cross-artifact analysis for {feature}
Phase 4 (RED)	test	red	{taskId} write failing test for {description}
Phase 4 (GREEN)	feat	green	{taskId} implement {description} to pass test
Phase 4 (REFACTOR)	refactor	-	{taskId} improve {description}
Phase 5	docs	optimize	complete optimization review for {feature}
Phase 6	docs	preview	create release notes for {feature} v{version}

Body generation:

Phase commits: Include metrics (task count, criteria count, etc.)
Task commits: Include evidence (tests, coverage, commit hash)
Fix commits: Include root cause and solution

See references/commit-templates.md for complete templates. </commit_message_generation> </quick_start>

Check for uncommitted changes when:

Phase command completes
task-tracker mark-done-with-notes called
User mentions "commit", "save progress", etc.

bash

# Check for uncommitted changes
git status --porcelain

# If non-empty output → uncommitted changes exist

</detection_phase>

<classification_phase> 2. Classify Change Type and Extract Context

Phase completion:

Extract phase name from workflow state or command
Extract feature slug from current directory
Get artifact file paths (spec.md, plan.md, etc.)

Task completion:

Extract TaskId from task-tracker parameters or conversation
Extract task description from tasks.md
Get phase marker ([RED], [GREEN], [REFACTOR])
Extract evidence (tests, coverage) from completion context

File modification:

Analyze changed files to infer purpose
Check git log for recent commit patterns
Default to "chore" type if unclear </classification_phase>

<validation_phase> 3. Validate Safety Before Committing

Check 1: Branch safety

bash

CURRENT_BRANCH=$(git branch --show-current)

if [[ "$CURRENT_BRANCH" =~ ^(main|master)$ ]]; then
  ❌ BLOCKED: Direct commits to main/master not allowed
  Recommendation: git checkout -b feat/{feature-slug}
  Exit code: 1
fi

if [[ ! "$CURRENT_BRANCH" =~ ^(feat|feature|bugfix|fix|hotfix|chore)/ ]]; then
  ⚠️ WARNING: Branch name doesn't follow convention
  Expected: feat/*, bugfix/*, hotfix/*, chore/*
  Current: $CURRENT_BRANCH
  Proceed? (auto-yes in non-interactive mode)
fi

Check 2: Merge conflicts

bash

# Check for conflict markers
if grep -r "<<<<<<<" . --exclude-dir=.git; then
  ❌ BLOCKED: Unresolved merge conflicts detected
  Resolve conflicts before committing
  Exit code: 1
fi

# Check git status for conflicts
if git status | grep -q "both modified"; then
  ❌ BLOCKED: Merge conflicts in git status
  Run: git status
  Exit code: 1
fi

Check 3: Remote tracking

bash

# Check if branch has upstream
if ! git rev-parse --abbrev-ref @{upstream} &>/dev/null; then
  ⚠️ WARNING: Branch has no upstream tracking
  Recommendation: git push -u origin $(git branch --show-current)
  Continue without upstream? (auto-yes)
fi

Check 4: Commit message format

bash

# Validate Conventional Commits format
COMMIT_MSG="$1"

# Check format: type(scope): subject
if ! [[ "$COMMIT_MSG" =~ ^(feat|fix|docs|test|refactor|perf|chore|ci|build|revert)(\([a-z0-9-]+\))?: ]]; then
  ❌ INVALID: Commit message doesn't follow Conventional Commits
  Expected: type(scope): subject
  Got: $COMMIT_MSG

  Auto-fix? (yes)
  → Prepend "chore: " to message
fi

# Check subject length (<50 chars recommended)
SUBJECT=$(echo "$COMMIT_MSG" | head -1)
if [[ ${#SUBJECT} -gt 72 ]]; then
  ⚠️ WARNING: Subject line too long (${#SUBJECT} > 72 chars)
  Recommendation: Keep under 50 chars for readability
fi

See references/validation-rules.md for complete validation logic. </validation_phase>

<commit_generation_phase> 4. Generate and Execute Commit

Stage files:

bash

# Get list of changed files
CHANGED_FILES=$(git status --porcelain | awk '{print $2}')

# Stage all changed files (auto-add for convenience)
git add $CHANGED_FILES

# Or stage all (if in feature directory)
git add specs/$FEATURE_SLUG/

Generate commit message:

bash

# Use template based on context
if [[ "$CONTEXT" == "phase_complete" ]]; then
  TYPE="docs"
  SCOPE="$PHASE_NAME"
  SUBJECT="create $ARTIFACTS for $FEATURE_SLUG"

  BODY="- Artifacts: $(echo $ARTIFACTS | tr '\n' ', ')
- Phase: $PHASE_NAME
- Feature: $FEATURE_SLUG"

elif [[ "$CONTEXT" == "task_complete" ]]; then
  # Extract from tasks.md
  PHASE_MARKER=$(grep "$TASK_ID" tasks.md | grep -oP '\[([A-Z]+)\]' | tr -d '[]')

  if [[ "$PHASE_MARKER" == "RED" ]]; then
    TYPE="test"
    SCOPE="red"
  elif [[ "$PHASE_MARKER" == "GREEN" ]]; then
    TYPE="feat"
    SCOPE="green"
  elif [[ "$PHASE_MARKER" == "REFACTOR" ]]; then
    TYPE="refactor"
    SCOPE=""
  fi

  SUBJECT="$TASK_ID $(extract_task_description)"

  BODY="Implementation: $NOTES
Tests: $EVIDENCE
Coverage: $COVERAGE"
fi

# Construct full message
COMMIT_MESSAGE="${TYPE}(${SCOPE}): ${SUBJECT}

${BODY}"

Execute commit:

bash

git commit -m "$(cat <<EOF
$COMMIT_MESSAGE
EOF
)"

COMMIT_HASH=$(git rev-parse --short HEAD)

echo "✅ COMMITTED: $COMMIT_HASH"
echo "  Rollback: git revert $COMMIT_HASH"

See references/auto-commit-logic.md for detailed generation rules. </commit_generation_phase>

<verification_phase> 5. Verify and Provide Feedback

Verify commit succeeded:

bash

# Check that working tree is now clean
if [ -n "$(git status --porcelain)" ]; then
  ⚠️ WARNING: Working tree still dirty after commit
  Uncommitted files: $(git status --short)
  Manual review needed
fi

# Get commit details
COMMIT_HASH=$(git rev-parse --short HEAD)
COMMIT_MSG=$(git log -1 --pretty=%B)
COMMIT_TIME=$(git log -1 --format=%ar)
CHANGED_FILES=$(git diff-tree --no-commit-id --name-only -r HEAD | wc -l)

Provide feedback:

markdown

✅ **AUTO-COMMIT SUCCESSFUL**

**Commit:** $COMMIT_HASH ($COMMIT_TIME)
**Message:** $COMMIT_MSG
**Files:** $CHANGED_FILES changed
**Branch:** $(git branch --show-current)

**Working tree:** Clean
**Rollback:** git revert $COMMIT_HASH
**Push:** git push

Check for unpushed commits:

bash

UNPUSHED=$(git log @{u}.. --oneline 2>/dev/null | wc -l)

if [[ $UNPUSHED -gt 0 ]]; then
  ⚠️ **REMINDER: Unpushed Commits**

  You have $UNPUSHED unpushed commit(s) on this branch.

  Push to backup:
  git push
fi

</verification_phase>

<safety_checks> Blocking checks (prevent commit):

❌ On main/master branch (unless deployment phase)
❌ Unresolved merge conflicts
❌ Invalid commit message format (auto-fixable with prompt)

Warning checks (allow but warn):

⚠️ Branch name doesn't follow conventions
⚠️ No upstream tracking configured
⚠️ Commit subject line >50 chars
⚠️ Unpushed commits exist

Auto-fix attempts:

Branch: Suggest git checkout -b feat/{slug}
Message format: Prepend "chore: " if type missing
Upstream: Suggest git push -u origin {branch}

See references/safety-checks.md for complete check logic. </safety_checks>

<anti_patterns> Avoid these mistakes:

1. Bundling multiple phases in one commit

bash

❌ BAD:
git commit -m "complete spec, plan, and tasks"

✅ GOOD:
git commit -m "docs(spec): create specification for user-messaging"
git commit -m "docs(plan): create implementation plan for user-messaging"
git commit -m "docs(tasks): create task breakdown for user-messaging"

2. Committing to main/master directly

bash

❌ BAD:
(on main) git commit -m "feat: add feature"

✅ GOOD:
git checkout -b feat/user-messaging
git commit -m "feat: add message model"

3. Vague commit messages

bash

❌ BAD:
git commit -m "fixes"
git commit -m "updates"
git commit -m "WIP"

✅ GOOD:
git commit -m "fix(api): correct message validation logic"
git commit -m "refactor: extract MessageService from controller"

4. Skipping commits between tasks

bash

❌ BAD:
# Implement T001, T002, T003
git commit -m "implement all tasks"

✅ GOOD:
# Implement T001
git commit -m "feat(green): T001 implement Message model"
# Implement T002
git commit -m "feat(green): T002 implement MessageService"
# Implement T003
git commit -m "feat(green): T003 add /messages endpoint"

5. Not checking for conflicts before commit

bash

❌ BAD:
git commit -m "fix: update model"
# Later: ❌ Push rejected, conflicts with remote

✅ GOOD:
git fetch
git merge origin/main
# Resolve any conflicts
git commit -m "fix: update model after merge"

</anti_patterns>

<success_criteria> Git workflow enforcement working when:

✓ Uncommitted changes automatically committed after phase/task completion
✓ Commit messages follow Conventional Commits format
✓ Commits blocked on main/master (redirected to feature branch)
✓ Merge conflicts detected and block commit
✓ Branch naming conventions validated
✓ Unpushed commits detected and warned
✓ Working tree always clean between phases
✓ Every task has dedicated commit with hash in NOTES.md
✓ Rollback points available for every phase and task
✓ Commit subject lines concise (<50 chars recommended)

Safety checks passing when:

Protected branches (main/master) have no direct commits
All commits follow type(scope): subject format
No unresolved merge conflict markers in codebase
Branches have upstream tracking configured
Clear rollback procedures available </success_criteria>
