---# LLM Gate
Use Claude Code's `type: "prompt"` hooks to create intelligent quality gates that use AI to verify operations.
## Trigger
Use when:
- Setting up commit message validation
- Enforcing code conventions beyond what linters catch
- Creating smart guardrails for specific operations
## How Prompt Hooks Work
Claude Code supports hooks with `type: "prompt"` that run a small LLM (Haiku by default) to verify conditions:
```json
{
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"type": "prompt",
"if": "Bash(git commit*)",
"prompt": "Check if this git commit follows conventional commit format (<type>(<scope>): <summary>). The commit command is: $ARGUMENTS. Return {\"ok\": true} if valid, {\"ok\": false, \"reason\": \"...\"} if not.",
"model": "haiku",
"timeout": 15
}]
}]
}
```
The hook:
1. Substitutes `$ARGUMENTS` with the JSON hook input
