# docs(hooks): document missing HookDecision values (`ask`, `approve`)

### What happened?

The Hooks reference documentation in `docs/hooks/reference.md` does not list all supported values for the `decision` field.

The documentation currently states:

```markdown
| `decision` | `string` | `"allow"` or `"deny"` (alias `"block"`). Specific impact depends on the event. |

### What did you expect to happen?

### What did you expect to happen?

```markdown
The Hooks reference should document all supported `HookDecision` values so that the documentation accurately reflects the TypeScript implementation:

- `ask`
- `approve`
- `block`
- `allow`
- `deny`

### Client information

- **Platform:** Windows
- **Component:** Gemini CLI Hooks documentation
- **Affected file:** `docs/hooks/reference.md`

The `/about` output is not applicable because this is a documentation-only issue.

### Login information

Not applicable. This issue does not depend on the authentication method.

### Anything else we need to know?

Relevant source locations:

- `docs/hooks/reference.md` around line 72
- `packages/core/src/hooks/types.ts` around lines 130–136

The documentation should be updated to remain consistent with the `HookDecision` type definition.

Open docs/hooks/reference.md around line 72 and compare the decision field with packages/core/src/hooks/types.ts around lines 130–136. Update the reference to list ask, approve, block, allow, and deny, then verify the documentation matches the HookDecision definition.
