+# git-flow
+
+Git workflow automation with intelligent commit messages and branch management.
+
+## Overview
+
+git-flow streamlines common git operations with smart defaults, conventional commit messages, and workflow enforcement. It supports multiple branching strategies and adapts to your team's workflow.
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/commit` | Create commit with auto-generated conventional message |
+| `/commit-push` | Commit and push in one operation |
+| `/commit-merge` | Commit and merge into target branch |
+| `/commit-sync` | Full sync: commit, push, and rebase on base branch |
+| `/branch-start` | Start new feature/fix/chore branch |
+| `/branch-cleanup` | Clean up merged branches |
+| `/git-status` | Enhanced status with recommendations |
+| `/git-config` | Configure git-flow settings |
+
+## Workflow Styles
+
+| Style | Description | Best For |
+|-------|-------------|----------|
+| `simple` | Direct commits to main | Solo projects |
+| `feature-branch` | Feature branches, merge when done | Small teams |
+| `pr-required` | All changes via pull request | Code review workflows |
+| `trunk-based` | Short-lived branches, frequent integration | CI/CD heavy |
+
+## Installation
+
+Add to your project's `.claude/settings.json`:
+
+```json
+{
+  "plugins": ["git-flow"]
+}
+```
+
+## Configuration
+
+Set environment variables in `.env` or `~/.config/claude/git-flow.env`:
+
+```bash
+GIT_WORKFLOW_STYLE=feature-branch
+GIT_DEFAULT_BASE=development
+GIT_AUTO_DELETE_MERGED=true
+GIT_AUTO_PUSH=false
+GIT_PROTECTED_BRANCHES=main,master,development,staging
+GIT_COMMIT_STYLE=conventional
+GIT_CO_AUTHOR=true
+```
+
+Or use `/git-config` for interactive configuration.
+
+## Features
+
+### Smart Commit Messages
+
+Analyzes staged changes to generate appropriate conventional commit messages:
+
+```
+feat(auth): add password reset functionality
+
+Implement forgot password flow with email verification.
+Includes rate limiting and token expiration.
+```
+
+### Branch Naming
+
+Enforces consistent branch naming:
+
+```
+feat/add-user-authentication
+fix/login-timeout-error
+chore/update-dependencies
+```
+
+### Safety Checks
+
+- Warns before commits to protected branches
+- Confirms force push operations
+- Prevents accidental branch deletion
+
+### Conflict Resolution
+
+The git-assistant agent helps resolve merge conflicts with analysis and recommendations.
+
+## Usage Examples
+
+### Start a Feature
+
+```
+/branch-start add user authentication
+
+→ Created: feat/add-user-authentication
+  Based on: development
+```
+
+### Commit Changes
+
+```
+/commit
+
+→ Analyzing changes...
+→ Proposed: feat(auth): add login component
+→ Committed: abc1234
+```
+
+### Full Sync
+
+```
+/commit-sync
+
+→ Committed: abc1234
+→ Pushed to origin
+→ Rebased on development
+→ Status: Clean, up-to-date
+```
