+## 2.5.2 - 2026-06-18
+
+### Fixes
+- `codex-imagegen`: stop Codex from satisfying a request by copying an unrelated pre-existing image from `generated_images` instead of generating a new one. Verification now requires real evidence that `image_gen` ran in the current thread — an `image_gen` event in the stream **or** a PNG in this thread's `generated_images` dir — and the spawned-agent instruction forbids reading or reusing history images before `image_gen` is called ([#185](https://github.com/JimLiu/baoyu-skills/issues/185))
+
+### Documentation
+- README: document Codex project-level install (`.agents/skills`) and project- vs user-level WeChat credential scopes

+## 2.5.2 - 2026-06-18
+
+### 修复
+- `codex-imagegen`：阻止 Codex 通过复制 `generated_images` 中无关旧图片来代替真正生成的取巧行为。校验改为要求当前线程内 `image_gen` 真正运行的证据——事件流中的 `image_gen` 事件，**或**当前线程 `generated_images` 目录下新生成的 PNG——并在派生 agent 指令中禁止在调用 `image_gen` 之前读取或复用历史图片（[#185](https://github.com/JimLiu/baoyu-skills/issues/185)）

+### 文档
