## Hook Events Overview

### How Hooks Are Called
**agent-turn-complete hook** (config.toml) — JSON passed as CLI argument:
```
python3 .codex/hooks/scripts/hooks.py '{"type":"agent-turn-complete"}'
```
**SessionStart / Stop hooks** (hooks.json) — called with `--hook` flag:
All hooks (hooks.json) are called with `--hook` flag:

python3 .codex/hooks/scripts/hooks.py --hook PostToolUse
python3 .codex/hooks/scripts/hooks.py --hook Stop
python3 .codex/hooks/scripts/hooks.py --hook UserPromptSubmit
