## 0.1.1 - 2026-09-12
- Continue indefinitely while each new structured HTTP 429 failure is emitted.
- Keep the delay fixed at 3 seconds for every attempt.
## 0.1.0 - 2026-09-11
- Detect structured Codex HTTP 429 task failures.

## 功能
- 只识别结构化的 `response_too_many_failed_attempts` HTTP 429 失败记录。
- 每次续跑统一等待 3 秒；同一失败链最多由插件发起四次续跑。
- 每次续跑统一等待 3 秒；每条结构化 429 都会继续触发下一次续跑，不设总次数上限。
- Codex 提供原生重试或继续工具时优先使用；否则只向原任务发送“继续”。
- 通过 `SessionStart` 支持新建和重新打开的任务，通过 `UserPromptSubmit` 为安装前已经加载的任务补启动监听。
- 如果 Codex 或用户已经开始新一轮任务，取消当前等待中的续跑。

When a Codex task ends with the structured `response_too_many_failed_attempts` HTTP 429 error, this plugin continues the same task through the Codex desktop app. It prefers a native retry/continue tool when Codex exposes one and otherwise sends `继续`.
The plugin starts one watcher per loaded session. `SessionStart` covers new and reopened sessions, while `UserPromptSubmit` backfills watchers for sessions that were already loaded when the plugin was installed. It gives Codex's built-in retry a chance to start first; when no new task has started, every continuation attempt waits exactly 3 seconds. A successful completion or 15 minutes without a plugin-initiated retry resets the chain. Prompt text, assistant text, and tool output containing `429` do not trigger it.
The plugin starts one watcher per loaded session. `SessionStart` covers new and reopened sessions, while `UserPromptSubmit` backfills watchers for sessions that were already loaded when the plugin was installed. It gives Codex's built-in retry a chance to start first; when no new task has started, every continuation attempt waits exactly 3 seconds. Every structured 429 can trigger another continuation with no total attempt limit. Prompt text, assistant text, and tool output containing `429` do not trigger it.
The watcher requires `node` on `PATH` and the Codex desktop app to remain open. Continuations appear in the original task. The watcher exits on `SessionEnd` or after 24 hours without transcript activity. Detection and delivery events are recorded under the plugin data directory as per-session JSONL logs.
