Git-Town Contribution Workflow — STOP AND READ

This workflow guides you through a complete contribution cycle using git-town.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

⛔ WORKFLOW ENFORCEMENT

YOU MUST USE GIT-TOWN COMMANDS. RAW GIT BRANCH COMMANDS ARE FORBIDDEN.

Phase 0: Preflight — MANDATORY

Step 0.1: Create TodoWrite

TodoWrite with todos:
- "[Contribute] Phase 0: Verify fork workflow is configured" | in_progress
- "[Contribute] Phase 0: Check workspace is clean" | pending
- "[Contribute] Phase 0: Sync with upstream" | pending
- "[Contribute] Phase 1: GATE - Confirm feature branch creation" | pending
- "[Contribute] Phase 1: Create feature branch with git town hack" | pending
- "[Contribute] Phase 2: Implement changes" | pending
- "[Contribute] Phase 2: Commit changes (raw git allowed here)" | pending
- "[Contribute] Phase 2: Sync branch before PR" | pending
- "[Contribute] Phase 3: GATE - Confirm PR creation" | pending
- "[Contribute] Phase 3: Create PR with git town propose" | pending
- "[Contribute] Phase 4: (Optional) Ship PR with git town ship" | pending

Step 0.2: Verify Fork Workflow Configured

/usr/bin/env bash << 'VERIFY_FORK_EOF'
echo "=== FORK WORKFLOW VERIFICATION ==="

# Check remotes
ORIGIN=$(git remote get-url origin 2>/dev/null)
UPSTREAM=$(git remote get-url upstream 2>/dev/null)

if [[ -z "$UPSTREAM" ]]; then
    echo "❌ FATAL: upstream remote not configured"
    echo "Run: /git-town-workflow:fork to configure"
    exit 1
fi

echo "✅ origin: $ORIGIN"
echo "✅ upstream: $UPSTREAM"

# Check git-town config
SYNC_UPSTREAM=$(git config git-town.sync-upstream 2>/dev/null)
if [[ "$SYNC_UPSTREAM" != "true" ]]; then
    echo "⚠️ WARNING: git-town.sync-upstream is not true"
    echo "Run: git config git-town.sync-upstream true"
fi

# Check current branch
CURRENT_BRANCH=$(git branch --show-current)
echo "Current branch: $CURRENT_BRANCH"

VERIFY_FORK_EOF

If verification fails:

AskUserQuestion with questions:
- question: "Fork workflow is not configured. Run fork setup first?"
  header: "Setup Required"
  options:
    - label: "Yes, run /git-town-workflow:fork now"
      description: "Configure fork workflow first"
    - label: "No, abort"
      description: "Cannot proceed without fork setup"
  multiSelect: false

Step 0.3: Check Workspace Clean

/usr/bin/env bash -c 'git status --porcelain'

If workspace has changes:

AskUserQuestion with questions:
- question: "Workspace has uncommitted changes. How to proceed?"
  header: "Dirty Workspace"
  options:
    - label: "Stash changes (Recommended)"
      description: "git stash, create branch, git stash pop"
    - label: "Commit changes first"
      description: "Create commit before new branch"
    - label: "Discard changes"
      description: "WARNING: Loses uncommitted work"
    - label: "Abort"
      description: "Handle manually"
  multiSelect: false

Step 0.4: Sync with Upstream

ALWAYS sync before creating feature branch:

git town sync

If conflicts occur:

1. Display conflict files
2. Wait for user to resolve
3. Run git town continue

Phase 1: Create Feature Branch

Step 1.1: GATE — Confirm Branch Creation

AskUserQuestion with questions:
- question: "What is the feature branch name?"
  header: "Branch Name"
  options:
    - label: "feat/{feature-name}"
      description: "Standard feature branch"
    - label: "fix/{bug-name}"
      description: "Bug fix branch"
    - label: "docs/{doc-name}"
      description: "Documentation branch"
    - label: "Enter custom name"
      description: "I'll provide the full branch name"
  multiSelect: false

Step 1.2: Create Branch with git-town

⛔ NEVER use git checkout -b. ALWAYS use:

git town hack {branch-name}

This command:

1. Fetches from origin and upstream
2. Creates branch from updated main
3. Sets up tracking correctly
4. Updates parent chain

Step 1.3: Verify Branch Created

/usr/bin/env bash << 'VERIFY_BRANCH_EOF'
BRANCH=$(git branch --show-current)
echo "Current branch: $BRANCH"

# Verify parent is main
git town branch
VERIFY_BRANCH_EOF

Phase 2: Implement & Commit

Step 2.1: Implement Changes

User implements their changes here.

(This phase is handled by the user or other skills)

Step 2.2: Stage and Commit (Raw git allowed)

Raw git IS allowed for commits:

git add .
git commit -m "feat: description of change"

Commit message format:

• feat: - New feature
• fix: - Bug fix
• docs: - Documentation
• refactor: - Code refactoring
• test: - Tests
• chore: - Maintenance

Step 2.3: Sync Before PR

⛔ NEVER use git pull or git push. ALWAYS use:

git town sync

This:

1. Pulls changes from upstream/main
2. Rebases/merges feature branch
3. Pushes to origin (your fork)

If conflicts:

AskUserQuestion with questions:
- question: "Sync encountered conflicts. What next?"
  header: "Conflicts"
  options:
    - label: "I'll resolve conflicts manually"
      description: "Fix conflicts, then run: git town continue"
    - label: "Skip conflicting changes"
      description: "Run: git town skip (may lose changes)"
    - label: "Abort sync"
      description: "Run: git town undo"
  multiSelect: false

Phase 3: Create Pull Request

Step 3.1: GATE — Confirm PR Creation

AskUserQuestion with questions:
- question: "Ready to create a pull request to upstream?"
  header: "Create PR"
  options:
    - label: "Yes, create PR to upstream"
      description: "Run: git town propose"
    - label: "No, keep working"
      description: "Continue development, create PR later"
    - label: "Create draft PR"
      description: "Create PR but mark as draft"
  multiSelect: false

Step 3.2: Create PR with git-town

⛔ NEVER create PR manually. ALWAYS use:

git town propose

This:

1. Pushes latest changes to origin
2. Opens browser to create PR
3. Targets correct upstream repository
4. Fills in branch info

For draft PR:

git town propose --draft

Step 3.3: Verify PR Created

/usr/bin/env bash -c 'gh pr view --json url,state,title'

Phase 4: Ship (After PR Approved)

Step 4.1: GATE — Confirm Ship

AskUserQuestion with questions:
- question: "Has your PR been approved and ready to merge?"
  header: "Ship PR"
  options:
    - label: "Yes, ship it (merge to main)"
      description: "Run: git town ship"
    - label: "Not yet, PR is pending review"
      description: "Wait for approval"
    - label: "PR was merged via GitHub UI"
      description: "Just cleanup local branches"
  multiSelect: false

Step 4.2: Ship with git-town

⛔ NEVER merge manually. ALWAYS use:

git town ship

This:

1. Verifies PR is approved
2. Merges to main
3. Deletes feature branch (local + remote)
4. Updates local main

Step 4.3: Post-Ship Cleanup

/usr/bin/env bash << 'CLEANUP_EOF'
echo "=== POST-SHIP STATUS ==="

# Show current branch
git branch --show-current

# Show recent commits on main
git log --oneline -5

# Verify feature branch deleted
git branch -a | grep -v "^*" | head -10

echo "✅ Ship complete"
CLEANUP_EOF

Stacked Branches (Advanced)

Creating Child Branches

If your feature needs to be split into smaller PRs:

# On feature branch, create child
git town append child-feature

# Creates stack:
# main
#   └── feature
#         └── child-feature

Navigating Stacks

git town up      # Go to parent branch
git town down    # Go to child branch
git town branch  # Show full stack hierarchy

Shipping Stacks

Ship from bottom up:

git town ship feature        # Ships feature first
git town ship child-feature  # Then ship child

Error Recovery

Undo Last git-town Command

git town undo

Continue After Resolving Conflicts

git town continue

Skip Conflicting Branch in Sync

git town skip

Check git-town Status

git town status

Troubleshooting

Post-Execution Reflection

After this skill completes, reflect before closing the task:

1. Locate yourself. — Find this SKILL.md's canonical path (Glob for this skill's name) before editing. All corrections target THIS file and its sibling references/ — never other documentation.
2. What failed? — Fix the instruction that caused it. If it could recur, add it as an anti-pattern.
3. What worked better than expected? — Promote it to recommended practice. Document why.
4. What drifted? — Any script, reference, or external dependency that no longer matches reality gets fixed now.
5. Log it. — Every change gets an evolution-log entry with trigger, fix, and evidence.

Do NOT defer. The next invocation inherits whatever you leave behind.
