Git Workflow

Instructions

Step 1: Identify the Task

Determine which workflow the user needs:

1. Commit message - writing or improving a commit message
2. Branching strategy - choosing or implementing a branching model
3. Conflict resolution - resolving merge conflicts
4. Changelog - generating release notes from commit history

Ask clarifying questions only if the intent is ambiguous.

Step 2: Conventional Commits

When writing commit messages, follow the Conventional Commits specification:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Types (in order of frequency):

• feat - new feature (correlates with MINOR in semver)
• fix - bug fix (correlates with PATCH in semver)
• docs - documentation only
• style - formatting, no code change
• refactor - neither fix nor feature
• perf - performance improvement
• test - adding or fixing tests
• chore - build process, tooling, dependencies
• ci - CI/CD configuration changes

Rules:

• Description is lowercase, no period at end, max 72 characters
• Body wraps at 72 characters, explains what and why (not how)
• Breaking changes: add ! after type or BREAKING CHANGE: in footer

Examples:

feat(auth): add OAuth2 login with Google provider

Implements the OAuth2 authorization code flow for Google.
Stores tokens in encrypted session storage.

Closes #142

fix(api): prevent race condition in concurrent order creation

Added optimistic locking with version column check.
Returns 409 Conflict when version mismatch detected.

Step 3: Branching Strategies

Recommend based on team size and release cadence:

Trunk-Based Development (recommended for most teams):

• Single main branch, always deployable
• Short-lived feature branches (max 2 days)
• Feature flags for incomplete work
• Best for: CI/CD, small teams, frequent releases

GitHub Flow:

• main branch + feature branches
• PR-based review before merge
• Deploy from main after merge
• Best for: open source, SaaS with continuous deployment

GitFlow (only for complex release schedules):

• main, develop, feature/*, release/*, hotfix/*
• Best for: packaged software, multiple supported versions
• Avoid unless you have a specific reason to use it

Provide the branching diagram and example commands for the chosen strategy.

Step 4: Conflict Resolution

When helping resolve conflicts:

1. Identify the conflict type:

   • Content conflict (same lines changed)
   • Rename conflict (file renamed differently)
   • Delete/modify conflict (one branch deleted, other modified)

2. Show both sides clearly:

   <<<<<<< HEAD (your changes)
   [your code]
   =======
   [their code]
   >>>>>>> feature-branch (incoming changes)
   

3. Suggest resolution strategy:

   • Take ours (keep current branch)
   • Take theirs (accept incoming)
   • Merge both (combine changes)
   • Rewrite (neither version is correct)

4. Provide the resolved code and the commands:

   # After resolving
   git add <resolved-files>
   git commit  # or git rebase --continue
   

Step 5: Changelog Generation

Generate changelogs from conventional commits:

## [1.2.0] - 2024-01-15

### Added
- OAuth2 login with Google provider (#142)
- Rate limiting on public API endpoints (#156)

### Fixed
- Race condition in concurrent order creation (#163)
- Memory leak in WebSocket connection handler (#158)

### Changed
- Upgraded Node.js requirement to v18+ (BREAKING)

Process:

1. Parse commits since last tag: git log v1.1.0..HEAD --oneline
2. Group by type (feat=Added, fix=Fixed, refactor/perf=Changed)
3. Include PR/issue numbers
4. Highlight breaking changes prominently
5. Use Keep a Changelog format

Example

User says: "Write a commit message for adding email validation to the signup form"

Response:

feat(signup): add email validation with DNS MX record check

Validates email format client-side and verifies MX records server-side.
Displays inline error message when validation fails.
Debounces server check by 500ms to reduce API calls.

Closes #89

Guidelines

• Default to Conventional Commits format unless the project uses a different convention
• Keep commit descriptions under 72 characters
• Recommend trunk-based development unless the team has a specific need for GitFlow
• When resolving conflicts, always explain why the chosen resolution is correct
• For changelogs, include only user-facing changes unless generating internal release notes
• Never suggest force-pushing to shared branches without explicit warning
