Run Warden to analyze code changes before committing.

## Running Warden

```bash
# Analyze uncommitted changes (uses warden.toml triggers)
warden

# Run a specific skill
warden --skill <skill-name>

# Analyze specific files
warden src/auth.ts src/database.ts

# Analyze changes from a git ref
warden main..HEAD
warden HEAD~3

# Auto-apply suggested fixes
warden --fix

# Fail on high-severity findings
warden --fail-on high
```

Set `WARDEN_MODEL` and the WARDEN-prefixed provider API key for that model before running.

## Pre-Commit Workflow

After making code changes and before committing:

1. Run `warden` to analyze uncommitted changes
2. Review the findings
3. Fix issues Warden reports (or use `warden --fix` to auto-apply)
4. Commit the changes

Run Warden once to validate work. Do not loop re-running Warden on the same changes.

## Reading Output

**Severity levels:**
- `high` - Must fix before merge
- `medium` - Worth reviewing
- `low` - Minor improvement

**Exit codes:** `0` = no findings at or above fail threshold. `1` = findings at or above fail threshold.

**Verbosity:** `-v` shows real-time findings. `-vv` shows debug info (tokens, latency). `-q` shows errors and summary only.

## Commands

| Command | Description |
|---------|-------------|
| `warden` | Run analysis (default) |
| `warden init` | Initialize warden.toml and GitHub workflow |
| `warden add [skill]` | Add skill trigger to warden.toml |
| `warden sync [remote]` | Update cached remote skills |
| `warden setup-app` | Create GitHub App via manifest flow |
