+## 2.5.1 - 2026-06-13
+
+### Documentation
+- Image generation skills: document Cursor's native `GenerateImage` backend in the shared backend-selection rule, including prompt-based aspect-ratio guidance, tool-managed output handling, and `reference_image_paths` support.
+
+## 2.5.0 - 2026-06-12
+
+### Features
+- `baoyu-wechat-summary`: add per-group fact memory (`memory.md`). Objective facts corrected or confirmed by group members (e.g., the real cause behind an error message, the correct name of a product) persist across digests, so a mistake corrected once is never repeated. Writes are conservative — three-part threshold (specific fact + evidence + unchallenged), strict injection guardrails (statements only, never instructions to the bot; `@bot` is not a whitelist channel), provenance on every entry, and revision/expiry/dedup rules with a 30-entry cap. Memory is shared by the normal and roast versions
+- `baoyu-image-gen`: add Agnes AI image generation provider (by @Davidlaizz)
+- `baoyu-image-gen`: default to GA Gemini image endpoints and allow reference images with them (by @hypn4)
+- `baoyu-post-to-wechat`: add `content_source_url` support for the "阅读原文" link (by @NTLx)
+
+### Fixes
+- `baoyu-image-gen`: remove gcd from `resolveSize` so decimal aspect ratios are no longer distorted (by @Davidlaizz)
+- `baoyu-fetch`: parse YouTube `/embed/` URLs in `parseYouTubeVideoId` (by @Osamaali313)
+- `baoyu-image-gen`: tolerate Bun-on-Windows `EEXIST` errors from `mkdir(recursive)` (by @sandypoli-boop)
+
+### Documentation
+- Improve skill descriptions for better trigger accuracy (by @yanghaod2278827)
+- README: add book/ebook links and promote `baoyu-design` in skill listings
+
+## 2.4.1 - 2026-06-01
+
+### Fixes
+- `baoyu-md` and `baoyu-chrome-cdp`: bump npm package versions to `0.1.1` and refresh consuming skill dependencies/lockfiles so fresh installs pick up the Mermaid exports, bundled `assets/mermaid.min.js`, and Markdown Mermaid preprocessing exports required by `baoyu-markdown-to-html`, `baoyu-post-to-wechat`, `baoyu-post-to-weibo`, `baoyu-post-to-x`, `baoyu-danger-gemini-web`, and `baoyu-danger-x-to-markdown` ([#172](https://github.com/JimLiu/baoyu-skills/issues/172))
+
+## 2.4.0 - 2026-05-29
+
+### Features
+- `baoyu-wechat-summary`: add an `@bot` Q&A section to both the normal and roast digests. Messages mentioning `@bot` / `@精华bot` (customizable via the new `bot_aliases` preference) are detected during the skeleton pass and answered in a dedicated section — earnest and helpful in the normal version, snarky-but-substantive in the roast version. Answers draw only on the chat context and the model's own knowledge (no web access) and honestly flag anything that needs real-time data
+
+## 2.3.0 - 2026-05-28
+
+### Features
+- `baoyu-md`, `baoyu-markdown-to-html`, `baoyu-post-to-wechat`, `baoyu-post-to-x`: support Obsidian image wikilinks (`![[...]]`) alongside standard Markdown images, preserve mixed image order, and resolve Obsidian's default `Attachments/` paths (by @zcqqq)
+
+### Fixes
+- `baoyu-md`, `baoyu-post-to-x`: decode URL-encoded local image paths before resolution so filenames with spaces or CJK characters are handled correctly (by @zcqqq)
+- `baoyu-md`, `baoyu-post-to-x`: harden decoded image path handling so malformed percent escapes fall back safely instead of breaking placeholder extraction (by @zcqqq)
+
+## 2.2.1 - 2026-05-26
+
+### Documentation
+- `baoyu-image-gen`: surface `scripts/build-batch.ts` in SKILL.md's Usage section so the `outline.md` + `prompts/` → `batch.json` workflow (e.g., `baoyu-article-illustrator` output) is discoverable next to `--batchfile`. Clarify that all `scripts/...` paths in SKILL.md are relative to `{baseDir}` and point the Generation Mode table at `{baseDir}/scripts/build-batch.ts`. Update `build-batch.ts --help` to print `bun` / `npx -y bun` invocations with the `{baseDir}/scripts/...` layout used by the rest of the skill
+
+## 2.2.0 - 2026-05-25
+
+### Features
+- `baoyu-image-gen`: new `codex-cli` provider that wraps the `codex-imagegen` backend so the Codex `image_gen` tool is reachable through the standard `--provider` / batch / EXTEND.md flow. Uses the user's Codex subscription — no `OPENAI_API_KEY` required. Adds env vars `BAOYU_CODEX_IMAGEGEN_{BIN,CACHE_DIR,TIMEOUT_MS,RETRIES,LOG_FILE}` and resolves hyphenated provider names for `BAOYU_IMAGE_GEN_<PROVIDER>_*` overrides (e.g., `BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY`). `codex-cli` is never auto-selected — pin via `--provider codex-cli` or `default_provider: codex-cli` in EXTEND.md
+
+### Refactor
+- `codex-imagegen`: extracted from `scripts/codex-imagegen/` + `scripts/codex-imagegen.sh` to its own workspace package at `packages/baoyu-codex-imagegen/`. The bash shim is gone; `src/main.ts` now carries a `#!/usr/bin/env bun` shebang and is the sole entrypoint (`bun packages/baoyu-codex-imagegen/src/main.ts …` or, without bun on `PATH`, `npx -y bun …`). `scripts/sync-codex-imagegen.sh` keeps `skills/baoyu-image-gen/scripts/codex-imagegen/` in sync for skill self-containment
+
+### Documentation
+- `baoyu-cover-image`: replace the long inline `scripts/codex-imagegen.sh` invocation block in `SKILL.md` with a pointer to `references/codex-imagegen.md`, documenting the preferred `baoyu-image-gen --provider codex-cli` path and keeping the direct-wrapper fallback
+- `baoyu-article-illustrator`, `baoyu-comic`, `baoyu-infographic`, `baoyu-slide-deck`, `baoyu-xhs-images`: add a `Codex via codex exec` branch to each skill's backend-selection ladder and ship a per-skill `references/codex-imagegen.md` with the invocation contract (preferred path, fallback, stdout schema, batch semantics)
+- `docs/codex-imagegen-backend.md` and `CLAUDE.md`: update path layout and invocation examples to reflect the new workspace package location
+
+## 2.1.0 - 2026-05-24
+
+### Features
+- `baoyu-markdown-to-html`: render fenced ` ```mermaid ` code blocks to local PNG via shared Chrome (CDP) before the standard image-placeholder pipeline runs. New CLI flags: `--mermaid-theme <default|forest|dark|neutral|base>`, `--mermaid-scale <N>` (default `2` for @2x resolution), `--mermaid-bg <white|transparent|#hex>`, and `--no-mermaid` to disable rendering. Generated images land in `imgs/.mermaid-cache/mermaid-<hash>.png` and are deduplicated/reused across runs by a 12-char SHA-256 over `(code, theme, scale, background, mermaid version)`. The browser-side `<pre class="mermaid">` path is retained as a graceful fallback when Chrome is unavailable or a single block fails to render
+- `baoyu-post-to-wechat`, `baoyu-post-to-weibo`, `baoyu-post-to-x`: cascade the same Mermaid → PNG preprocessing into the WeChat / Weibo / X publishing pipelines so diagrams appear as real images in the published posts (previously they fell through as unrendered `<pre>` blocks). Existing `WECHATIMGPH_*` / `WBIMGPH_*` / `XIMGPH_*` placeholder pipelines pick up the generated PNGs unchanged
+- `baoyu-md` package: new exports `preprocessMermaidInMarkdown`, `extractMermaidBlocks`, `replaceMermaidBlocks`, `hashMermaidCode`, and `MERMAID_VERSION` (skills inject the render function so the package stays Chrome-free)
+- `baoyu-chrome-cdp` package: new `./mermaid` subexport providing `renderMermaidToPng(code, outputPath, options)` backed by a process-singleton CDP connection that reuses the shared Chrome profile and ships the vendored Mermaid 10.9.1 UMD bundle as an asset

+
+## 2.2.0 - 2026-05-25

+### 新功能
+- `baoyu-image-gen`：新增 `codex-cli` provider，封装 `codex-imagegen` 后端，让 Codex 内置的 `image_gen` 工具也能走标准的 `--provider` / 批量 / EXTEND.md 流程。使用用户自己的 Codex 订阅,无需 `OPENAI_API_KEY`。新增环境变量 `BAOYU_CODEX_IMAGEGEN_{BIN,CACHE_DIR,TIMEOUT_MS,RETRIES,LOG_FILE}`；`BAOYU_IMAGE_GEN_<PROVIDER>_*` 类覆盖项支持带连字符的 provider 名称(如 `BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY`)。`codex-cli` **不会**自动选用,需通过 `--provider codex-cli` 或 EXTEND.md 的 `default_provider: codex-cli` 显式指定
+
+### 重构
+- `codex-imagegen`：从 `scripts/codex-imagegen/` + `scripts/codex-imagegen.sh` 拆分为独立的 workspace 包 `packages/baoyu-codex-imagegen/`。bash 包装器已移除,`src/main.ts` 自带 `#!/usr/bin/env bun` shebang,作为唯一入口(`bun packages/baoyu-codex-imagegen/src/main.ts …`,若 `PATH` 中无 bun 则 `npx -y bun …`)。新增 `scripts/sync-codex-imagegen.sh` 同步 `skills/baoyu-image-gen/scripts/codex-imagegen/`,保持 skill 自包含
+
+### 文档
+- `baoyu-cover-image`：`SKILL.md` 中较长的 `scripts/codex-imagegen.sh` 内联调用块替换为指向 `references/codex-imagegen.md` 的链接,文档明确优先走 `baoyu-image-gen --provider codex-cli`、并保留直接调用 wrapper 的回退路径
+- `baoyu-article-illustrator`、`baoyu-comic`、`baoyu-infographic`、`baoyu-slide-deck`、`baoyu-xhs-images`：在各自 backend 选择阶梯中新增 `Codex via codex exec` 分支,并附带 per-skill 的 `references/codex-imagegen.md`(优先路径、回退、stdout schema、批量语义)
+- `docs/codex-imagegen-backend.md` 与 `CLAUDE.md`：同步新的 workspace 路径与调用示例
+

+
+### 新功能
+- `baoyu-markdown-to-html`：在标准图片占位符流水线之前,通过共享 Chrome（CDP）把 ` ```mermaid ` 围栏代码块渲染为本地 PNG。新增 CLI 参数 `--mermaid-theme <default|forest|dark|neutral|base>`、`--mermaid-scale <N>`（默认 `2`,即 @2x 分辨率）、`--mermaid-bg <white|transparent|#hex>`,以及用于关闭渲染的 `--no-mermaid`。生成的图片落在 `imgs/.mermaid-cache/mermaid-<hash>.png`,跨次运行通过对 `(code, theme, scale, background, mermaid 版本)` 取 SHA-256 前 12 位进行去重/复用。Chrome 不可用或单块渲染失败时,保留浏览器侧 `<pre class="mermaid">` 兜底
+- `baoyu-post-to-wechat`、`baoyu-post-to-weibo`、`baoyu-post-to-x`:在微信 / 微博 / X 发布流水线中同步接入上述 Mermaid → PNG 预处理,Mermaid 图能以真图形式出现在已发布的稿件中(此前会落到未渲染的 `<pre>` 块)。现有的 `WECHATIMGPH_*` / `WBIMGPH_*` / `XIMGPH_*` 占位符流水线无需改动,会直接拾取生成的 PNG
+- `baoyu-md` 包:新增导出 `preprocessMermaidInMarkdown`、`extractMermaidBlocks`、`replaceMermaidBlocks`、`hashMermaidCode`、`MERMAID_VERSION`(渲染函数由 skill 注入,本包不再反向依赖 Chrome)
+- `baoyu-chrome-cdp` 包:新增 `./mermaid` 子导出,提供 `renderMermaidToPng(code, outputPath, options)`,底层为进程级单例 CDP 连接,复用共享 Chrome profile,并把 Mermaid 10.9.1 UMD 资产打入包内

 ## Design Decisions
 
-1. **Bash entrypoint + TypeScript implementation** — the shell wrapper picks the runtime (`bun` preferred, falling back to `npx -y bun`); TypeScript handles the orchestration, parsing, retry, cache, and logging. This mirrors the project's existing `scripts/*.mjs` and `skills/<skill>/scripts/main.ts` pattern.
+1. **Pure TypeScript entrypoint** — `src/main.ts` carries a `#!/usr/bin/env bun` shebang and is the sole entry. There is no shell shim: callers either invoke `bun src/main.ts …` directly, run the file as an executable (when `bun` is on `PATH`), or fall back to `npx -y bun src/main.ts …`. This matches the project's `skills/<skill>/scripts/main.ts` convention.
 2. **`--sandbox danger-full-access`** — necessary so the spawned agent can `cp`/`mv` the rendered PNG out of `$CODEX_HOME/generated_images/` to the user-specified path. Standard sandboxes block this.
 3. **Parse the JSONL event stream** — the final `agent_message` and intermediate `command_execution` events let the wrapper verify what actually happened (was `image_gen` called? did `cp` reach the right destination?), which is far more reliable than scraping freeform stdout.
-4. **Infrastructure, not a skill** — this backend is a CLI utility that skills route to via `preferred_image_backend`. It belongs in `scripts/`, not `skills/`, because it has no `SKILL.md` and is never loaded directly by an agent.
+4. **Shared package, not a skill** — this backend is a CLI utility that skills route to via `preferred_image_backend` and that `baoyu-image-gen --provider codex-cli` spawns internally. It lives under `packages/` alongside the other shared workspaces (`baoyu-md`, `baoyu-chrome-cdp`, `baoyu-fetch`) because it has no `SKILL.md` and is never loaded directly by an agent.
 5. **File lock instead of internal queue** — keeps the implementation small and works across multiple shell sessions or processes invoking the same wrapper concurrently.

 ## The Rule
 
@@ -10,6 +10,7 @@ When a skill needs to render an image, resolve the backend in this order:
 2. **Saved preference** — if the skill's `EXTEND.md` sets `preferred_image_backend` to a backend available right now, use it.
 3. **Auto-select** (when the preference is `auto`, unset, or the pinned backend isn't available):
    - **Codex (`imagegen`)** — first, inspect your available-skills / tool inventory. If a skill named `imagegen` is listed, you are running inside Codex and MUST use it: invoke via the `Skill` tool with `skill: "imagegen"`, passing the saved prompt file's content (plus output path and aspect ratio per Codex `imagegen`'s own args). Codex `imagegen` is the official raster backend in that runtime and outranks any non-native skill (e.g., `baoyu-image-gen`) unless the user has explicitly pinned a different `preferred_image_backend`.
+   - **Cursor (`GenerateImage`)** — if the runtime exposes a native `GenerateImage` tool, you are running inside Cursor and it outranks any non-native skill the same way Codex `imagegen` does. Two hard caveats: (a) it has no aspect-ratio parameter — state the target aspect ratio / dimensions explicitly in the prompt text passed as `description`; (b) it does not accept an output directory — it saves to a tool-managed location, so after generation copy/move the file to the skill's expected output path (e.g., `outputs/.../NN-xxx.png`). Reference images go in `reference_image_paths`.
    - **Other runtime-native tools** — if the runtime exposes a different native image tool (e.g., Hermes `image_generate`), use it the same way.
    - Otherwise, if exactly one non-native backend is installed (e.g., `baoyu-image-gen`), use it.
    - Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.

+# baoyu-codex-imagegen
+
+Generate images via Codex CLI's built-in `image_gen` tool from non-Codex runtimes (e.g., Claude Code). The wrapper spawns `codex exec --json` and lets the user's existing Codex subscription drive image generation — **no `OPENAI_API_KEY` required**.
+
+This package implements the `preferred_image_backend: codex-imagegen` config key referenced across the `baoyu-skills` plugin and is the engine behind `baoyu-image-gen --provider codex-cli`.
+
+## Layout
+
+```
+packages/baoyu-codex-imagegen/
+├── src/
+│   ├── main.ts             # CLI orchestrator (executable via `#!/usr/bin/env bun`)
+│   ├── spawn.ts            # codex exec child-process wrapper
+│   ├── parser.ts           # JSONL event-stream parser
+│   ├── validator.ts        # Output PNG / image_gen-invocation verification
+│   ├── cache.ts            # SHA256 idempotency cache + file lock
+│   ├── logger.ts           # Structured JSONL logging
+│   ├── types.ts            # Shared types and `GenError`
+│   └── *.test.ts           # Bun unit tests
+└── package.json            # `bin` points to `src/main.ts`
+```
+
+## Prerequisites
+
+```bash
+npm install -g @openai/codex
+codex login            # signs in with your OpenAI account (subscription)
+codex --version        # confirm >= 0.130
+```
+
+`bun` is required for running the wrapper:
+
+```bash
+brew install oven-sh/bun/bun
+```
+
+If `bun` is not on `PATH`, `npx -y bun src/main.ts …` works as a fallback.
+
+## Usage
+
+```bash
+# Inline prompt (executes via shebang once bun is on PATH)
+./src/main.ts \
+  --image /tmp/cat.png \
+  --prompt "A friendly orange cat, watercolor"
+
+# Or invoke bun explicitly
+bun src/main.ts \
+  --image cover.png \
+  --prompt-file prompts/01-cover.md \
+  --aspect 16:9 \
+  --cache-dir ~/.cache/baoyu-codex-imagegen
+
+# Without bun installed
+npx -y bun src/main.ts --image cover.png --prompt "..."
+```
+
+Stdout emits a single JSON line:
+
+```json
+{"status":"ok","path":"…","bytes":1234567,"elapsed_seconds":62,"thread_id":"…","attempts":1,"cached":false,"usage":{…}}
+```
+
+On failure:
+
+```json
+{"status":"error","path":"…","bytes":0,"error":"…","error_kind":"timeout"}
+```
+
+`error_kind` values: `codex_not_installed`, `invalid_args`, `prompt_file_missing`, `spawn_failed`, `timeout`, `no_image_gen_tool_use`, `output_missing`, `invalid_png`, `agent_refused`, `lock_busy`.
+
+## Options
+
+| Flag | Description |
+|---|---|
+| `--image <path>` | Output PNG path (required) |
+| `--prompt <text>` | Prompt text |
+| `--prompt-file <path>` | Read prompt from file (mutually exclusive with `--prompt`) |
+| `--aspect <ratio>` | Aspect ratio (`1:1`, `16:9`, `9:16`, `4:3`, `2.35:1`). Default: `1:1` |
+| `--ref <file>` | Reference image (repeatable) |
+| `--timeout <ms>` | Codex exec timeout in ms. Default: `300000` |
+| `--retries <n>` | Retry attempts on retryable errors. Default: `2` |
+| `--retry-delay <ms>` | Base retry delay (exponential). Default: `1500` |
+| `--cache-dir <path>` | Enable idempotency cache. Disabled by default. |
+| `--log-file <path>` | Append structured JSONL log |
+| `-v, --verbose` | Verbose stderr logging |
+| `-h, --help` | Show help |
+
+## Test
+
+```bash
+cd packages/baoyu-codex-imagegen
+bun test
+```
+
+## Trade-offs
+
+- 5–10× slower than direct OpenAI API calls (except on cache hits)
+- Uses your Codex subscription — programmatic use of `codex exec` falls into the same terms as interactive use
+- Requires `codex` CLI and active login session
+
+See [`docs/codex-imagegen-backend.md`](../../docs/codex-imagegen-backend.md) for the full background.

+- **All filesystem inputs** are auto-resolved against `process.cwd()` when relative, but agents should pass absolute paths to be robust against cwd drift.

+- **`--cache-dir`** is off by default. Enable for repeatable runs to skip redundant generations of the same prompt+aspect+refs.
+- **Authentication**: the wrapper uses the user's Codex subscription — no `OPENAI_API_KEY` is read or sent.

+
+On retryable errors (timeout, spawn_failed, no_image_gen_tool_use, output_missing, invalid_png, agent_refused), ask the user whether to retry or fall back to another backend.
+
+## Batch semantics
+
+- Codex `image_gen` returns **one image per call** (`n=1` only). Multi-image jobs must dispatch one wrapper call per image.
+- The wrapper does NOT accept a `--sessionId` flag. Chain/scene consistency must come from `--ref` reference images.
+- `--size` and `--quality` are silently ignored — Codex picks pixel dimensions from `--aspect`.

+
+## Parameter notes
+
+- **All filesystem inputs** are auto-resolved against `process.cwd()` when relative, but agents should pass absolute paths to be robust against cwd drift.
+- **`--timeout`** defaults to `300000` (5 min) per `codex exec` attempt. Raise (e.g. `--timeout 600000` for 10 min) on slow networks or large prompts.
+- **`--cache-dir`** is off by default. Enable for repeatable runs to skip redundant generations of the same prompt+aspect+refs.
+- **Authentication**: the wrapper uses the user's Codex subscription — no `OPENAI_API_KEY` is read or sent.
+
+## Stdout contract
+
+Single JSON line:
+
+- Success: `{"status":"ok","path":"...","bytes":N,"elapsed_seconds":N,"thread_id":"...","attempts":N,"cached":bool,...}`
+- Failure: `{"status":"error","path":"...","bytes":0,"error":"...","error_kind":"..."}`
+
+`error_kind` values: `codex_not_installed`, `invalid_args`, `prompt_file_missing`, `spawn_failed`, `timeout`, `no_image_gen_tool_use`, `output_missing`, `invalid_png`, `agent_refused`, `lock_busy`.
+
+On retryable errors (timeout, spawn_failed, no_image_gen_tool_use, output_missing, invalid_png, agent_refused), ask the user whether to retry or fall back to another backend.
+
+## Batch semantics
+
+- Codex `image_gen` returns **one image per call** (`n=1` only). Multi-image jobs must dispatch one wrapper call per image.
+- The wrapper does NOT accept a `--sessionId` flag. Chain/scene consistency must come from `--ref` reference images.
+- `--size` and `--quality` are silently ignored — Codex picks pixel dimensions from `--aspect`.

+# Sapiens AI Agnes Image
+
+Read when the user picks `--provider agnes` or sets `default_model.agnes`. Default model is `agnes-image-2.1-flash`.
+
+## Models
+
+**`agnes-image-2.1-flash`** (only model)
+
+- Text-to-image and image-to-image (with `--ref`) in a single `/images/generations` endpoint
+- Supports reference images as public URLs or Data URI (base64)
+- Optimized for high information density, complex layouts, and rich details
+- Size rules: both dimensions divisible by 32 (720px exception), long edge ≤ 2048, total pixels ≤ ~4M
+- Default size: `1024x1024`; custom `--size` supports arbitrary WxH within the above rules
+- `--ar` supported: computed as 2048-based size (long edge ≤ 2048, short edge proportional, both snapped to 32px); `1:1` special-cased to `1024x1024`
+
+## Response Format
+
+- The sync API always returns a URL
+- Default (`--response-format file`): downloads the image and saves as `.png`
+- Pass `--response-format url`: writes the URL string to `.txt` instead
+
+## `--n` Behavior
+
+The Agnes API returns a single image per request regardless of the `n` parameter. Passing `--n > 1` triggers a local error from `validateArgs` before any API call is made.
+
+## Behavior Notes
+
+- API key required: `AGNES_API_KEY`
+- Base URL: `https://apihub.agnes-ai.com/v1` (override with `AGNES_BASE_URL`)
+- Model override: `AGNES_IMAGE_MODEL` env
+- `response_format` is always embedded in `extra_body` (not at request top level)
+- Reference images: local files converted to Data URI base64 inline; remote URLs passed through
+- Rate limit defaults: concurrency=3, startIntervalMs=1100 (override via `BAOYU_IMAGE_GEN_AGNES_CONCURRENCY` / `BAOYU_IMAGE_GEN_AGNES_START_INTERVAL_MS`)
+- Timeout: 120s per request
+
+## Size Resolution
+
+- `--size <WxH>` wins over `--ar`
+- `--ar` maps to a concrete size using the algorithm: long edge ≤ 2048, short edge proportional, both dimensions snapped to 32px
+- `--ar 1:1` is special-cased to `1024x1024`
+
+### Common `--ar` Results
+
+| Aspect Ratio | Result |
+|--------------|--------|
+| `1:1` | `1024x1024` |
+| `16:9` | `2048x1152` |
+| `4:3` | `2048x1536` |
+| `3:2` | `2048x1376` |
+| `21:9` | `2048x896` |
+| Unlisted ratio | Computed on the fly (portrait mirror swaps width/height) |

+# Codex CLI (`--provider codex-cli`)
+
+Read when the user picks `--provider codex-cli`, sets `default_provider: codex-cli`, or asks for "Codex image generation without an OpenAI API key". This provider is a thin baoyu-image-gen wrapper around the bundled `scripts/codex-imagegen/main.ts` (synced from `packages/baoyu-codex-imagegen`), which spawns `codex exec --json --sandbox danger-full-access` and routes the request to Codex CLI's built-in `image_gen` tool. The Codex CLI uses the **user's Codex / ChatGPT subscription** — no `OPENAI_API_KEY` is read or sent.
+
+## Prerequisites
+
+```bash
+npm install -g @openai/codex
+codex login            # signs in with the user's OpenAI / Codex account
+codex --version        # confirm >= 0.130
+```
+
+`bun` is required for running the underlying wrapper (`scripts/codex-imagegen/main.ts`, carrying `#!/usr/bin/env bun`). If `bun` is missing from the runtime, `npx -y bun` works as a fallback.
+
+## Selection
+
+- **Never auto-selected.** `detectProvider` only picks `codex-cli` when it is pinned explicitly: pass `--provider codex-cli` or set `default_provider: codex-cli` in EXTEND.md.
+- Choose this provider when:
+  - The user has a Codex subscription and explicitly does **not** want to manage an OpenAI API key.
+  - You need Codex's specific `image_gen` behavior or quality.
+- Avoid this provider when latency matters — Codex CLI is typically 5–10× slower than direct OpenAI / Google API calls (except on cache hits).
+
+## Supported flags
+
+| Flag | Behavior |
+|------|----------|
+| `--prompt <text>` / `--promptfiles <files>` | Required. Written to a temp file and passed to the wrapper as `--prompt-file`. |
+| `--image <path>` | Required. Final output PNG location. |
+| `--ar <ratio>` | Mapped to wrapper's `--aspect`. Supported by Codex: `1:1` (default), `16:9`, `9:16`, `4:3`, `2.35:1`. |
+| `--ref <files...>` | Mapped to wrapper's repeated `--ref`. Codex's `image_gen` accepts reference images for style/composition guidance. |
+| `--n` | Must be `1`. `validateArgs` throws if `n > 1` because Codex `image_gen` returns a single image per call. |
+| `--imageApiDialect` | Not applicable. Throws if set to a non-default value. |
+| `--size`, `--imageSize`, `--quality` | Silently ignored — Codex picks pixel dimensions from the aspect ratio. |
+| `--model`, `-m` | Logical label only. The wrapper does not forward a model selector to Codex; the underlying engine is whichever model Codex's `image_gen` currently uses. Default label: `codex-image-gen`. |
+
+## Environment variables
+
+| Variable | Effect |
+|----------|--------|
+| `BAOYU_CODEX_IMAGEGEN_BIN` | Override the wrapper path. Default: bundled `scripts/codex-imagegen/main.ts` resolved relative to this skill's installed location. Accepts a `.ts` file (spawned with `bun`) or a legacy `.sh`/binary (spawned directly). |
+| `BAOYU_CODEX_IMAGEGEN_CACHE_DIR` | Enable the wrapper's idempotency cache. Disabled by default; set to e.g. `~/.cache/baoyu-codex-imagegen` for high-value reuse. |
+| `BAOYU_CODEX_IMAGEGEN_TIMEOUT_MS` | Per-attempt `codex exec` timeout in ms. Default: `300000` (5 min). Raise for slow networks or large prompts. |
+| `BAOYU_CODEX_IMAGEGEN_RETRIES` | Wrapper-side retry attempts on retryable errors. Default: `2` (3 total attempts). |
+| `BAOYU_CODEX_IMAGEGEN_LOG_FILE` | Append a structured JSONL diagnostic log. Useful when triaging timeouts or `agent_refused` errors. |
+| `BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY` | Batch-mode concurrency for the `codex-cli` provider. Default: `1` — Codex exec is a heavy single-process workflow; raising this rarely helps. |
+| `BAOYU_IMAGE_GEN_CODEX_CLI_START_INTERVAL_MS` | Batch-mode minimum start-gap. Default: `2000` ms. |
+
+## Error model
+
+The wrapper emits a single JSON line on stdout. On failure:
+
+```json
+{"status":"error","path":"...","bytes":0,"error":"...","error_kind":"..."}
+```
+
+The provider re-throws each wrapper error as `Invalid codex-cli result (<error_kind>): <message>`. The `"Invalid "` prefix triggers `isRetryableGenerationError` to mark it **non-retryable** in baoyu-image-gen's outer retry loop — the wrapper has already retried internally per `BAOYU_CODEX_IMAGEGEN_RETRIES`, so re-spawning Codex from main.ts would only multiply latency without changing the outcome.
+
+`error_kind` values to expect:
+
+| Kind | Cause | Action |
+|------|-------|--------|
+| `codex_not_installed` | `codex` not on `PATH` or unreadable | `npm install -g @openai/codex`, then `codex login`. |
+| `invalid_args` | Programmer error in the spawn invocation | Inspect provider source; usually a path-injection guard fired. |
+| `prompt_file_missing` | Temp prompt file vanished mid-call | Retry once; check `$TMPDIR` permissions. |
+| `spawn_failed` | OS / process-launch failure | Verify `bun` or `npx` is installed; check filesystem permissions. |
+| `timeout` | `codex exec` exceeded `--timeout` | Raise `BAOYU_CODEX_IMAGEGEN_TIMEOUT_MS`; check network. |
+| `no_image_gen_tool_use` | Codex agent answered without calling `image_gen` | Often transient — retry. If persistent, refine the prompt. |
+| `output_missing` / `invalid_png` | Agent reported success but file is absent or not a valid PNG | Retry; check disk space. |
+| `agent_refused` | Codex agent refused (policy or content) | Adjust the prompt; surface the refusal to the user. |
+| `lock_busy` | Another `codex-imagegen` invocation holds the file lock | Wait or set a distinct `--cache-dir` per concurrent caller. |
+
+## Trade-offs
+
+- Slow: 5–10× direct OpenAI API latency (except cache hits).
+- Subject to the same TOS as interactive `codex exec` use — programmatic invocation from baoyu-image-gen is the same usage class.
+- Stateful: requires `codex login` to be live; an expired session manifests as `codex_not_installed` or `agent_refused`.
+
+## See also
+
+- `references/codex-oauth-vs-openai-api-key.md` — why Codex OAuth is not interchangeable with `OPENAI_API_KEY`.
+- `references/codex-image2-fallback.md` — when to fall back to `codex-cli` from a failed `openai` provider call.

 2. **Saved preference** — if `EXTEND.md` sets `preferred_image_backend` to a backend available right now, use it.
 3. **Auto-select** (when the preference is `auto`, unset, or the pinned backend isn't available):
    - **Codex (`imagegen`)** — first, inspect your available-skills / tool inventory. If a skill named `imagegen` is listed, you are running inside Codex and MUST use it: invoke via the `Skill` tool with `skill: "imagegen"`, passing the saved prompt file's content (plus output path and aspect ratio per Codex `imagegen`'s own args). Codex `imagegen` is the official raster backend in that runtime and outranks any non-native skill (e.g., `baoyu-image-gen`) unless the user has explicitly pinned a different `preferred_image_backend`.
+   - **Codex via `codex exec` (`codex-imagegen`)** — if the current runtime exposes no native `imagegen` skill but the `codex` CLI is on `PATH` with an active `codex login`, route through `baoyu-image-gen --provider codex-cli` (preferred), or — if baoyu-image-gen is unavailable — invoke the bundled wrapper directly. Details, parameters, and the runtime-discovery procedure live in [references/codex-imagegen.md](references/codex-imagegen.md) — load that file only when this branch is selected.
+   - **Cursor (`GenerateImage`)** — if the runtime exposes a native `GenerateImage` tool, you are running inside Cursor and it outranks any non-native skill the same way Codex `imagegen` does. Two hard caveats: (a) it has no aspect-ratio parameter — state the target aspect ratio / dimensions explicitly in the prompt text passed as `description`; (b) it does not accept an output directory — it saves to a tool-managed location, so after generation copy/move the file to the skill's expected output path (e.g., `outputs/.../NN-xxx.png`). Reference images go in `reference_image_paths`.
    - **Other runtime-native tools** — if the runtime exposes a different native image tool (e.g., Hermes `image_generate`), use it the same way.
    - Otherwise, if exactly one non-native backend is installed (e.g., `baoyu-image-gen`), use it.
    - Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.

+# `codex-imagegen` Wrapper Invocation
+
+Load this reference only when the [Image Generation Tools](../SKILL.md#image-generation-tools) rule has resolved to `codex-imagegen` — i.e., the current runtime exposes no native `imagegen` skill but `codex` CLI is on `PATH` with an active `codex login`.
+
+## Preferred path: route through `baoyu-image-gen`
+
+If the `baoyu-image-gen` skill is available in this runtime, **always** invoke through it rather than calling the wrapper directly. It handles retry/cache/batch/EXTEND.md preferences uniformly with every other provider.
+
+```bash
+${BUN_X} <baoyu-image-gen-base>/scripts/main.ts \
+  --provider codex-cli \
+  --image <ABSOLUTE_output> \
+  --promptfiles <ABSOLUTE_prompts/infographic.md> \
+  --ar <ratio> \
+  [--ref <ABSOLUTE_file>]...
+```
+
+Resolve `<baoyu-image-gen-base>` the same way you resolve any sibling skill — through your runtime's skill registry (`Skill` tool, plugin marketplace, or `$HOME/.baoyu-skills/baoyu-image-gen/`).
+
+## Fallback: spawn the wrapper directly
+
+Only when `baoyu-image-gen` is NOT installed in the current runtime. Discover the wrapper's location at runtime — do NOT hard-code `../../packages/...` from this skill:
+
+1. **Honor explicit override**: if `$BAOYU_CODEX_IMAGEGEN_BIN` is set and points to a real file, use that path. It may be `.ts` (spawn `bun <path>`) or `.sh`/binary (spawn directly).
+2. **Search the plugin root**: walk up from this skill's directory looking for `packages/baoyu-codex-imagegen/src/main.ts`. If found, that is the wrapper. Spawn it with `bun`.
+3. **Last resort**: tell the user that `codex-imagegen` is not available in this runtime and ask whether to install the `baoyu-skills` plugin (or set `BAOYU_CODEX_IMAGEGEN_BIN`) or pick another backend.
+
+Once located, the invocation shape is:
+
+```bash
+bun <WRAPPER>/main.ts \
+  --image <ABSOLUTE_output> \
+  --prompt-file <ABSOLUTE_prompts/infographic.md> \
+  --aspect <ratio> \
+  [--ref <ABSOLUTE_file>]... \
+  [--timeout <ms>] \
+  [--cache-dir ~/.cache/baoyu-codex-imagegen] \
+  [--log-file <ABSOLUTE_jsonl_log_path>]
+```
+
+If `bun` is missing, `npx -y bun <WRAPPER>/main.ts ...` works as a fallback.
+
+## Parameter notes
+
+- **All filesystem inputs** are auto-resolved against `process.cwd()` when relative, but agents should pass absolute paths to be robust against cwd drift.
+- **`--timeout`** defaults to `300000` (5 min) per `codex exec` attempt. Raise (e.g. `--timeout 600000` for 10 min) on slow networks or large prompts.
+- **`--cache-dir`** is off by default. Enable for repeatable runs to skip redundant generations of the same prompt+aspect+refs.
+- **Authentication**: the wrapper uses the user's Codex subscription — no `OPENAI_API_KEY` is read or sent.
+
+## Stdout contract
+
+Single JSON line:
+
+- Success: `{"status":"ok","path":"...","bytes":N,"elapsed_seconds":N,"thread_id":"...","attempts":N,"cached":bool,...}`
+- Failure: `{"status":"error","path":"...","bytes":0,"error":"...","error_kind":"..."}`
+
+`error_kind` values: `codex_not_installed`, `invalid_args`, `prompt_file_missing`, `spawn_failed`, `timeout`, `no_image_gen_tool_use`, `output_missing`, `invalid_png`, `agent_refused`, `lock_busy`.
+
+On retryable errors (timeout, spawn_failed, no_image_gen_tool_use, output_missing, invalid_png, agent_refused), ask the user whether to retry or fall back to another backend.
+
+## Batch semantics
+
+- Codex `image_gen` returns **one image per call** (`n=1` only). Multi-image jobs must dispatch one wrapper call per image.
+- The wrapper does NOT accept a `--sessionId` flag. Chain/scene consistency must come from `--ref` reference images.
+- `--size` and `--quality` are silently ignored — Codex picks pixel dimensions from `--aspect`.
