Git Release Workflow

Purpose

Executes the git operations for a release: running pre-release hooks, staging modified files, creating a commit with proper formatting and attribution, creating an annotated git tag with configurable patterns, and running post-release hooks. Works with any project type.

Input Context

Requires:

• Project Configuration: Output from detect-project-type skill
• Version: New version string (e.g., "1.2.0")
• Commit Message: Pre-formatted commit message (from changelog-update skill)
• Files to Stage: List of modified files to include in commit

Workflow

1. Load Configuration

Use configuration from detect-project-type:

• tag_pattern - Pattern for git tag (e.g., "v{version}", "{package}-v{version}")
• tag_message - Message template for annotated tag
• commit_message_template - Template for commit message
• pre_release_hook - Script to run before git operations (optional)
• post_release_hook - Script to run after successful push (optional)

2. Run Pre-Release Hook

If preReleaseHook is configured, execute it before any git operations:

if [ -n "$pre_release_hook" ]; then
  echo "Running pre-release hook: $pre_release_hook"

  if [ -x "$pre_release_hook" ]; then
    # Run hook and capture output
    if ! hook_output=$($pre_release_hook 2>&1); then
      # Hook failed - abort release
      echo "✗ Pre-release hook failed:"
      echo "$hook_output"
      exit 1
    else
      echo "✓ Pre-release hook succeeded"
      echo "$hook_output"
    fi
  else
    echo "⚠️  Pre-release hook not executable: $pre_release_hook"
    exit 1
  fi
fi

Common pre-release hook use cases:

• Run tests: npm test, cargo test, go test ./...
• Build project: npm run build, cargo build --release
• Run linters: npm run lint, cargo clippy
• Generate documentation: npm run docs
• Validate package: npm pack --dry-run, twine check dist/*

3. Stage Modified Files

Stage all files that were modified during the release process:

git add {file1} {file2} {file3} ...

Files typically include:

• Version configuration files (plugin.json, marketplace.json, variants.json)
• Changelog files (CHANGELOG.md)
• Documentation files (README.md)

Verify staging succeeded:

git status --short

2. Create Commit

Create commit with the provided message, ensuring proper formatting and attribution:

git commit -m "$(cat <<'EOF'
{commit-message}

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
EOF
)"

Commit message format:

Release {scope} v{version}

{changelog-body}

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Important: Use heredoc (<<'EOF') to preserve formatting and handle multi-line messages correctly.

Capture commit hash:

git rev-parse HEAD

5. Create Annotated Git Tag

Create an annotated tag (not lightweight) using configurable pattern from configuration:

Build tag name from pattern:

# Get pattern from config (e.g., "v{version}", "{package}-v{version}")
tag_pattern="v{version}"  # from config

# Replace placeholders
tag_name="${tag_pattern//\{version\}/$new_version}"

# For monorepo/plugins, also replace {package}
if [[ "$tag_pattern" == *"{package}"* ]]; then
  tag_name="${tag_name//\{package\}/$package_name}"
fi

# Examples:
# Pattern: "v{version}" → Tag: "v1.2.0"
# Pattern: "release-{version}" → Tag: "release-1.2.0"
# Pattern: "{package}-v{version}" → Tag: "my-lib-v1.2.0"

Build tag message from template:

# Get template from config (default: "Release v{version}")
tag_message_template="Release v{version}"  # from config

# Replace placeholders
tag_message="${tag_message_template//\{version\}/$new_version}"
tag_message="${tag_message//\{package\}/$package_name}"

# Example: "Release v1.2.0"

Create tag:

git tag -a "$tag_name" -m "$tag_message"

Verify tag created:

if git tag -l "$tag_name" | grep -q "$tag_name"; then
  echo "✓ Created tag: $tag_name"
else
  echo "✗ Failed to create tag: $tag_name"
  exit 1
fi

4. Prepare Push Information

Do NOT automatically push. Instead, prepare information for the command to display:

# Get remote URL
git remote get-url origin

# Get current branch
git branch --show-current

# Show what will be pushed
git log origin/{branch}..HEAD --oneline

Return push command for user to execute:

git push origin {branch} --follow-tags

Or if using --force-with-lease after rebase:

git push origin {branch} --follow-tags --force-with-lease

6. Run Post-Release Hook (After Push)

Note: This section is executed by the /release command AFTER successful push, not within this skill.

If postReleaseHook is configured, execute it after git push succeeds:

if [ -n "$post_release_hook" ]; then
  echo "Running post-release hook: $post_release_hook"

  if [ -x "$post_release_hook" ]; then
    # Run hook and capture output
    if ! hook_output=$($post_release_hook 2>&1); then
      # Hook failed - warn but don't abort (release already pushed)
      echo "⚠️  Post-release hook failed:"
      echo "$hook_output"
      # Continue anyway - release is already public
    else
      echo "✓ Post-release hook succeeded"
      echo "$hook_output"
    fi
  else
    echo "⚠️  Post-release hook not executable: $post_release_hook"
  fi
fi

Common post-release hook use cases:

• Publish package: npm publish, cargo publish, twine upload dist/*
• Deploy to CDN/hosting: netlify deploy, vercel --prod
• Send notifications: ./scripts/notify-slack.sh, ./scripts/post-to-discord.sh
• Update documentation site: ./scripts/deploy-docs.sh
• Trigger CI/CD: curl -X POST $CI_WEBHOOK_URL
• Create GitHub release: gh release create $TAG_NAME

7. Generate Summary

Collect information for post-release summary:

• Commit hash (short: first 7 characters)
• Tag name
• Files committed (count)
• Current branch
• Remote URL (if configured)

{
  "commit_hash": "a1b2c3d",

Integration Notes

This skill is invoked by the /release command in Phase 6. The command will:

1. Execute git operations via this skill
2. Display commit hash and tag name
3. Prompt user to push with provided command
4. If user confirms, execute push:

   git push origin {branch} --follow-tags
   

5. Proceed to Phase 7 for verification

Git Best Practices

• Always use annotated tags (-a flag) for releases (contains metadata)
• Use heredoc for multi-line commit messages to preserve formatting
• Include Co-Authored-By for attribution when Claude assists
• Use --follow-tags when pushing to include annotated tags
• Never force push unless explicitly requested and using --force-with-lease
• Verify operations after each git command (check status, verify tag exists)

Linear History Maintenance

To maintain linear git history:

• Commit directly to master/main (no merge commits)
• If on feature branch, rebase onto master first
• Use fast-forward merges only
• Avoid git merge --no-ff
