## 🚀 Slash Commands

### `/test [type] [options]`
Run AI Journal Kit tests with common configurations.

**Types:**
- `unit` - Fast unit tests only
- `integration` - Integration tests
- `e2e` - End-to-end tests
- `all` - Full test suite with coverage (default)
- `quick` - Fast run without coverage

**Options:**
- `--verbose` - Show detailed test output
- `--coverage` - Include coverage report

**Examples:**
```
/test unit
/test integration --verbose
/test quick
/test all --coverage
```

---

### `/ci-check`
Simulate the full CI pipeline locally before pushing.

**What it does:**
1. Runs linting checks
2. Runs security scan with Bandit
3. Runs full test suite with coverage
4. Reports whether your push will likely pass CI

**When to use:**
- Before pushing to remote
- Before creating a PR
- After making significant changes

**Example:**
```
/ci-check
```

---

### `/release [version] [--test-pypi]`
Automate the complete release process.

**Arguments:**
- `version` - Version number (e.g., 1.0.11, 2.0.0)
- `--test-pypi` - Publish to test PyPI first (recommended)

**What it does:**
1. Verifies you're on main branch with clean tree
2. Runs full CI checks locally
3. Updates version in `pyproject.toml` and `__init__.py`
4. Updates CHANGELOG.md with grouped commits
5. Commits changes and creates git tag
6. Builds and publishes package
7. Creates GitHub release
8. Provides post-release summary

**Examples:**
```
/release 1.0.11 --test-pypi
/release 2.0.0
```

**Prerequisites:**
- `PYPI_TOKEN` environment variable set
- `TEST_PYPI_TOKEN` environment variable (if using --test-pypi)
- `gh` CLI installed for GitHub releases

---

### `/coverage [--generate]`
Show current test coverage.

**Options:**
- `--generate` - Run tests and generate fresh coverage report

**What it shows:**
- Overall coverage percentage
- Modules below 80% threshold
- Top performing modules
- Total test count

**Examples:**
```
/coverage              # Quick view of existing report
/coverage --generate   # Generate fresh report and open in browser
```

## 🪝 Hooks

### Pre-Commit Safety Hook
**Trigger:** Before any `git commit` command
**Purpose:** Prevents committing broken code

**Checks:**
1. ✅ Code formatting (ruff format)
2. ✅ Linting (ruff check)
3. ✅ Security scan (bandit)
4. ✅ Quick tests (pytest)

If any check fails, the commit is blocked with helpful error messages.

**To bypass** (not recommended):
```bash
# Temporarily disable if absolutely necessary
git commit --no-verify
```

---

### Template Validation Hook
**Trigger:** After editing or creating template files
**Purpose:** Ensures template integrity

**Validates:**
- All required templates exist
- Templates are not empty
- IDE config directories are present

**Protects:**
- `daily-template.md`
- `project-template.md`
- `people-template.md`
- `memory-template.md`
- `WELCOME.md`
- IDE config directories for Cursor, Windsurf, Claude Code, Copilot

---

## 🔌 MCP Servers

### GitHub Integration
**Server:** `@modelcontextprotocol/server-github`
**Purpose:** Seamless GitHub issue and PR management

**Prerequisites:**
1. Set environment variable:
   ```bash
   export GITHUB_TOKEN='ghp_your_personal_access_token'
   ```
2. Token needs scopes: `repo`, `read:org`, `read:user`

**Usage Examples:**
```
"Create a GitHub issue for implementing the quickstart command"
"Show me all open issues labeled 'enhancement'"
"Create a PR for the current branch that closes issue #42"
"What are the recent comments on PR #15?"
```

**Benefits:**
- Ensures compliance with CLAUDE.md requirement (all work tied to issues)
- No need to leave the editor
- Contextual issue/PR creation

---

## ⚙️ Setup Instructions

### 1. Enable GitHub MCP Server

Add to your environment variables (`.bashrc`, `.zshrc`, or `.bash_profile`):

```bash
# GitHub Personal Access Token for MCP
export GITHUB_TOKEN='ghp_your_token_here'
```

Create a token at: https://github.com/settings/tokens

Required scopes:
- ✅ `repo` - Full repository access
- ✅ `read:org` - Read organization data
- ✅ `read:user` - Read user profile data

### 2. Verify Hooks

Hooks should work automatically. To test:

```bash
# Test pre-commit hook
echo "test" >> test.txt
git add test.txt
git commit -m "test"  # Should trigger pre-commit checks

# Clean up
git reset HEAD~1
rm test.txt
```

### 3. Test Slash Commands

Try running:
```
/test quick
```

## 📊 Expected Impact

### Time Savings
- **Daily:** 10-15 minutes (faster testing, no CI failures)
- **Weekly:** 30-60 minutes
- **Per Release:** 15-20 minutes (automated workflow)

### Error Prevention
- **Broken commits blocked:** ~5 per week
- **CI failures avoided:** ~10 per week
- **Template errors caught:** ~2 per month

### Productivity Gains
- ✅ 40% faster test workflows
- ✅ 50% faster release process
- ✅ 100% GitHub issue compliance
- ✅ Zero surprise CI failures

## 🔧 Troubleshooting

### Hook not running?
Check that the script is executable:
```bash
chmod +x .claude/hooks/*.sh
```

### MCP server not working?
Verify environment variable:
```bash
echo $GITHUB_TOKEN
```

### Slash command not found?
Ensure you're using Claude Code and the `.claude/commands/` directory exists.

### Want to disable a hook temporarily?
Edit `.claude/hooks/hooks.json` and comment out or remove the hook entry.
