+# Codex Bridge 异步完成通知 MVP 需求
+
+## 背景
+
+Hermes 通过 `skills/codex-bridge/references/cli.py start` 启动 Codex app-server stdio 任务后，会把任务状态写入本地 `codex_bridge.db`。当前实现不是常驻订阅或完成回调模式：Codex turn 完成后不会主动通知原 Feishu/平台会话，用户必须再次说“继续”后 Hermes 才会手动查询 `status` 或 `list`。
+
+这造成一个产品异味：异步任务已经启动，但完成后没有人主动查收。
+
+## 范围决策
+
+本次做窄范围 MVP：让 Codex Bridge 启动的异步任务在完成后能回到原会话或目标发送完成摘要。不要做多租户调度系统，不重写现有 Codex Bridge 低层协议，不引入 mailbox/outbox/inbox 作为主通信机制。
+
+## 目标
+
+- 启动任务时可选记录通知目标，例如 `local`、`feishu:<chat_id>` 或其他 `send_message` 支持的显式平台目标。
+- 默认不改变现有 API 行为；未传通知目标时仍能正常启动和查询。
+- 提供 watcher/one-shot poll 入口，发现已完成但未处理通知的任务。
+- 对有目标的任务读取 final summary，生成简洁完成摘要，并通过可注入 notifier 发送。
+- 对无目标的完成任务标记为 `no_target`，避免 watcher 重启后重复处理。
+- 通过持久化 `notification_status` / `notified_at` 防重复通知。
+
+## 非目标
+
+- 不实现常驻多租户调度器。
+- 不实现 pending approval / `requestUserInput` 的实时双向交互。
+- 不让测试向真实 Feishu、WeChat、Telegram 等外部平台发消息。
+- 不开放 `danger-full-access` 默认权限。
+- 不用 mailbox/outbox/inbox 作为通信机制。
+
+## 验收标准
+
+- `codex_bridge(action="start", notify_target=...)` 能把目标写入任务状态。
+- watcher/notify 入口只通知 terminal 状态任务一次；重启或重复运行不会重复发送。
+- terminal 任务没有 target 时会被标记为 `no_target`，不会调用 notifier。
+- CLI 暴露 `--notify-target` 和 one-shot `notify-completed` 入口，并支持 dry-run。
+- 测试通过 mock/inject notifier 覆盖通知行为。
+
+## 后续扩展说明
+
+pending approval 和 `requestUserInput` 后续可复用同一通知目标字段：当任务进入 `waiting_for_approval` 或 `waiting_for_user_input` 时，watcher 可以发送带 request id 的交互提示；平台侧回复再映射到 `codex_bridge respond`。本次先只处理 terminal completion，避免把交互式审批设计混入 MVP。

+# Codex Bridge 异步完成通知 MVP 实现计划
+
+## 问题框架
+
+Codex Bridge 已能通过 app-server stdio 启动异步 Codex turn，并把状态写入 `codex_bridge.db`。缺口在完成后的主动送达：当前没有通知目标、通知状态，也没有 watcher 入口来把 terminal 任务的摘要回发给原会话。
+
+## 技术决策
+
+- 在 `codex_bridge_tasks` 上新增通知元数据：`notify_target`、`notification_status`、`notified_at`、`notification_error`。
+- `start` 接受可选 `notify_target`，不传时保持旧行为。
+- 新增 one-shot `notify_completed` action：扫描 terminal 且尚未处理通知的任务，按目标发送或标记 `no_target`。
+- 默认 notifier 复用现有 `send_message` 工具；测试和 CLI dry-run 通过注入或 dry-run 避免真实外发。
+- `local` 目标作为本地消费目标：记录为已通知并返回摘要，不调用外部平台。
+
+## 实现单元
+
+### U1: 持久化通知目标与状态
+
+修改文件：
+- `tools/codex_bridge_tool.py`
+- `tests/tools/test_codex_bridge_tool.py`
+
+做法：
+- 数据库初始化时对旧库执行兼容迁移。
+- `CodexBridgeTask.snapshot()`、`list_tasks()`、`get_task_snapshot()` 暴露通知字段。
+- `start_task()` 接受 `notify_target` 并保存。
+
+测试场景：
+- 启动任务时传入 `notify_target`，状态快照和持久化查询都能看到该值。
+
+### U2: 完成通知 one-shot watcher
+
+修改文件：
+- `tools/codex_bridge_tool.py`
+- `tests/tools/test_codex_bridge_tool.py`
+
+做法：
+- 增加扫描 terminal 任务的方法。
+- 对无 target 的任务标记 `no_target`，不调用 notifier。
+- 对有 target 的任务构造简洁摘要，调用 notifier 后标记 `sent` 和 `notified_at`。
+- 已 `sent` 或 `no_target` 的任务不再重复处理。
+- 支持 `dry_run`，只返回会处理的任务，不写通知状态，不发送。
+
+测试场景：
+- completed 任务只通知一次。
+- 无 target completed 任务不发送，并标记 `no_target`。
+- dry-run 不发送且不改变通知状态。
+
+### U3: 工具 schema 与 CLI 入口
+
+修改文件：
+- `tools/codex_bridge_tool.py`
+- `skills/codex-bridge/references/cli.py`
+- `skills/codex-bridge/references/validator.py`
+- `tests/skills/test_codex_bridge_skill.py`
+
+做法：
+- schema 加入 `notify_completed` action、`notify_target`、`dry_run`。
+- CLI `start`/`smoke-test` 增加 `--notify-target`。
+- CLI 增加 `notify-completed` one-shot 命令。
+- validator 校验 notify 输出的基本结构。
+
+测试场景：
+- CLI start 能把 `--notify-target` 传给工具。
+- CLI notify-completed dry-run 调用 bridge 且不依赖真实平台。
+
+## 验证
+
+- `python -m py_compile tools/codex_bridge_tool.py skills/codex-bridge/references/cli.py skills/codex-bridge/references/validator.py`
+- `scripts/run_tests.sh tests/tools/test_codex_bridge_tool.py tests/skills/test_codex_bridge_skill.py`
+
+## 风险
+
+- 默认 notifier 依赖 `send_message` 的运行环境；没有 gateway 或目标不可达时会记录 `notification_error` 并保留可重试状态。
+- 当前只处理 terminal completion，不处理实时 approval/input；后续应在同一 target 模型上扩展。

+
+# Codex Bridge 异步任务需要持久化完成通知状态
+
+## Context
+
+Codex Bridge 已经通过 app-server stdio 启动 Codex 任务，并把状态写入 `codex_bridge.db`。dogfood 暴露出的体验问题是：异步任务完成后没有主动通知原 Feishu/平台会话，用户必须再次触发 Hermes 查询 `status` 或 `list` 才能知道结果。
+
+这类问题不需要先做多租户调度系统。MVP 的关键是让任务在启动时可选记录通知目标，并让一个 one-shot watcher 可以可靠地处理 terminal 任务。
+
+## Guidance
+
+在已有任务表上补齐三个概念，而不是重写底层通信协议：
+
+- `notify_target`：启动时可选记录目标，例如 `local` 或 `feishu:<chat_id>`。
+- `notification_status`：记录通知生命周期，例如 `pending`、`sent`、`failed`、`no_target`。
+- `notified_at` / `notification_error`：让 watcher 重启后能防重复，并保留失败原因。
+
+watcher 应该只扫描 terminal 状态任务，并做幂等处理：
+
+- 有目标：构造简洁完成摘要，调用可注入 notifier，成功后标记 `sent`。
+- 无目标：标记 `no_target`，不发送，避免每次扫描重复捞到同一任务。
+- dry-run：返回预览，不发送，也不写通知状态。
+
+默认 notifier 可以复用现有 `send_message` 能力，但核心 manager 方法要允许注入 notifier。这样单元测试可以用 fake notifier 验证行为，避免真实平台副作用。
+
+## Why This Matters
+
+异步 bridge 的产品承诺不是“能启动后台任务”，而是“任务结束后用户能在原上下文看到结果”。如果只有状态表但没有通知状态，系统会卡在“完成但无人查收”的灰区；如果没有持久化防重复，watcher 或 daemon 重启又可能重复推送。
+
+把通知状态做成任务元数据，可以在不引入 mailbox/outbox/inbox 通信机制的情况下满足 MVP，并为后续实时 approval / `requestUserInput` 扩展留下同一套 target 语义。
+
+## When to Apply
+
+- 异步任务生命周期已经持久化，但完成后需要跨平台送达。
+- 现有平台发送能力已经存在，新增功能只需要选择目标和调用发送。
+- 需要保证测试环境不触发真实外部消息。
+- 需要 watcher/daemon 重启后不重复通知。
+
+## Examples
+
+启动时记录目标：
+
+```python
+codex_bridge(
+    action="start",
+    prompt="Investigate the failing tests",
+    notify_target="feishu:chat-1",
+)
+```
+
+one-shot watcher dry-run：
+
+```bash
+python skills/codex-bridge/references/cli.py notify-completed --dry-run
+```
+
+测试中注入 notifier：
+
+```python
+deliveries = []
+manager.notify_completed(
+    notifier=lambda target, message: deliveries.append((target, message)) or {"ok": True}
+)
+```
