-- **Unsupported hook events (23 of Claude Code's current 30):** `Setup`, `InstructionsLoaded`, `UserPromptExpansion`, `MessageDisplay`, `PermissionRequest`, `PostToolUseFailure`, `PostToolBatch`, `PermissionDenied`, `Notification`, `TaskCreated`, `TaskCompleted`, `StopFailure`, `TeammateIdle`, `ConfigChange`, `CwdChanged`, `FileChanged`, `WorktreeCreate`, `WorktreeRemove`, `PreCompact`, `PostCompact`, `SessionEnd`, `Elicitation`, and `ElicitationResult`. Config for these events is parsed but never dispatched. The comparison baseline is Claude Code's [official hook-event reference](https://code.claude.com/docs/en/hooks#hook-events).

Config for these events is ignored before group parsing, so an unsupported event cannot invalidate or register hooks. The comparison baseline is Claude Code's [official hook-event reference](https://code.claude.com/docs/en/hooks#hook-events).
 - **`SessionStart` is partial:** JSON `additionalContext` is consumed, but plain stdout context, `initialUserMessage`, `sessionTitle`, `watchPaths`, `reloadSkills`, and `CLAUDE_ENV_FILE` are unsupported. The hook runs detached, so context can miss the first request (`TODO(session-start-gating)`), and the payload omits current optional fields such as `model`, `agent_type`, and `session_title`.
 - **`UserPromptSubmit` is partial:** blocking and JSON `additionalContext` work, but plain stdout context, `sessionTitle`, and `suppressOriginalPrompt` are unsupported. Unless overridden, the bridge also uses its 600-second default instead of Claude Code's event-specific 30-second command timeout.
 - **`PreToolUse` is partial:** `deny` and `ask` decisions work; `allow` does not pre-approve, `defer` is unsupported, `additionalContext` is ignored, and `updatedInput` is logged + warned but not honored ([the pre-tool-input-rewrite Agent Note](../../../.agents/notes/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)).

 - **`SessionStart` 只支持部分功能：** 会消费 JSON `additionalContext`，但不支持纯 stdout 上下文、`initialUserMessage`、`sessionTitle`、`watchPaths`、`reloadSkills` 与 `CLAUDE_ENV_FILE`。hook 脱离运行，因此上下文可能错过第一个请求（`TODO(session-start-gating)`），payload 会省略 `model`、`agent_type` 和 `session_title` 等当前可选字段。
 - **`UserPromptSubmit` 只支持部分功能：** 支持阻塞与 JSON `additionalContext`，但不支持纯 stdout 上下文、`sessionTitle` 和 `suppressOriginalPrompt`。除非被覆盖，否则桥接还会使用自身 600 秒默认值，而非 Claude Code 的事件特定 30 秒 command 超时。
 - **`PreToolUse` 只支持部分功能：** `deny` 与 `ask` 决策可用；`allow` 不会预批准，不支持 `defer`，`additionalContext` 会被忽略，`updatedInput` 会被记录 + 警告但不应用（见 [pre-tool-input-rewrite Agent Note](../../../.agents/notes/proposed/feature/2026-06-30-pre-tool-input-rewrite.md)）。
