## Description

Claude Code supports 4 hook handler types. dotforge only documented `command`.

| Type | Description |
|------|-------------|
| `command` | Shell script (bash/powershell) |
| `http` | HTTP POST to endpoint |
| `prompt` | Single-turn LLM prompt for decision |
| `agent` | Spawn full subagent for verification |

## Incorporated

- Added hook types to `.claude/rules/domain/hook-architecture.md`
- Added "Hook types in settings.json" section to `stacks/hookify/rules/hookify.md` with examples
  and note that hookify generates `command` type; others must be added manually to settings.json
