+# /commit - Smart Commit
+
+## Purpose
+
+Create a git commit with an auto-generated conventional commit message based on staged changes.
+
+## Behavior
+
+### Step 1: Analyze Changes
+
+1. Run `git status` to see staged and unstaged changes
+2. Run `git diff --staged` to examine staged changes
+3. If nothing staged, prompt user to stage changes
+
+### Step 2: Generate Commit Message
+
+Analyze the changes and generate a conventional commit message:
+
+```
+<type>(<scope>): <description>
+
+[optional body]
+
+[optional footer]
+```
+
+**Types:**
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation only
+- `style`: Formatting, missing semicolons, etc.
+- `refactor`: Code change that neither fixes a bug nor adds a feature
+- `perf`: Performance improvement
+- `test`: Adding/updating tests
+- `chore`: Maintenance tasks
+- `build`: Build system or external dependencies
+- `ci`: CI configuration
+
+**Scope:** Determined from changed files (e.g., `auth`, `api`, `ui`)
+
+### Step 3: Confirm or Edit
+
+Present the generated message:
+
+```
+Proposed commit message:
+───────────────────────
+feat(auth): add password reset functionality
+
+Implement forgot password flow with email verification.
+Includes rate limiting and token expiration.
+───────────────────────
+
+Options:
+1. Use this message (Recommended)
+2. Edit the message
+3. Regenerate with different focus
+4. Cancel
+```
+
+### Step 4: Execute Commit
+
+If confirmed, run:
+
+```bash
+git commit -m "$(cat <<'EOF'
+<message>
+
+Co-Authored-By: Claude <noreply@anthropic.com>
+EOF
+)"
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `GIT_COMMIT_STYLE` | `conventional` | Message style (conventional, simple, detailed) |
+| `GIT_SIGN_COMMITS` | `false` | Use GPG signing |
+| `GIT_CO_AUTHOR` | `true` | Include Claude co-author footer |
+
+## Edge Cases
+
+### No Changes Staged
+
+```
+No changes staged for commit.
+
+Would you like to:
+1. Stage all changes (`git add -A`)
+2. Stage specific files (I'll help you choose)
+3. Cancel
+```
+
+### Untracked Files
+
+```
+Found 3 untracked files:
+- src/new-feature.ts
+- tests/new-feature.test.ts
+- docs/new-feature.md
+
+Include these in the commit?
+1. Yes, stage all (Recommended)
+2. Let me pick which ones
+3. No, commit only tracked files
+```
+
+## Output
+
+On success:
+```
+Committed: abc1234
+feat(auth): add password reset functionality
+
+Files: 3 changed, 45 insertions(+), 12 deletions(-)
+```
