 English | [中文](./CHANGELOG.zh.md)

+## 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
+
+## 2.0.1 - 2026-05-24
+
+### Fixes
+- `baoyu-post-to-wechat`: convert `newspic` (image-text) `content` from HTML to plain text before sending to the WeChat draft API. The previous behavior passed raw HTML, triggering error 45166 (invalid content) when multiple images pushed the body over WeChat's length limit. The new `htmlToPlainText` helper turns `<br>` and block-closing tags into line breaks, strips remaining tags, decodes named/numeric (decimal and hex) entities, and collapses whitespace (by @Go1dFinger, [#164](https://github.com/JimLiu/baoyu-skills/pull/164), closes [#163](https://github.com/JimLiu/baoyu-skills/issues/163))
+
+### Credits
+- `baoyu-post-to-wechat` newspic plain-text fix contributed by @Go1dFinger ([#164](https://github.com/JimLiu/baoyu-skills/pull/164))
+
+## 2.0.0 - 2026-05-24
+
+### Breaking
+- Removed `baoyu-imagine` skill. All functionality (providers, scripts, references) now lives under `baoyu-image-gen`. The skill is registered in `marketplace.json` under the new name and its `homepage` URL has changed to `#baoyu-image-gen`.
+- Removed `baoyu-image-cards` skill. All functionality (styles, layouts, palettes, presets) now lives under `baoyu-xhs-images`. The skill is registered in `marketplace.json` under the new name.
+- Cross-skill `## Image Generation Tools` examples in `baoyu-article-illustrator`, `baoyu-comic`, `baoyu-cover-image`, `baoyu-infographic`, and `baoyu-slide-deck` now reference `baoyu-image-gen` instead of `baoyu-imagine`.
+
+### Migration
+- Existing `~/.baoyu-skills/baoyu-imagine/EXTEND.md` and `.baoyu-skills/baoyu-imagine/EXTEND.md` configs are auto-renamed to `…/baoyu-image-gen/EXTEND.md` on first run via the legacy-path resolver in `scripts/main.ts`.
+- Users invoking the skill via slash command should switch from `/baoyu-imagine ...` to `/baoyu-image-gen ...` and from any `baoyu-image-cards` reference to `baoyu-xhs-images`.
+
+## 1.119.0 - 2026-05-24
+
+### Features
+- `baoyu-electron-extract`: new skill that extracts resources and JavaScript from any installed Electron app's `app.asar`. Restores original sources from embedded `sourcesContent` in `.js.map` files when present (TypeScript/JSX included) or formats minified JS/CSS with Prettier in place when not. Source-map paths are resolved relative to each `.js.map` file first, so bundler-relative entries like `../../src/main.ts` restore to readable paths under `restored/` instead of hashed placeholders. Always skips `node_modules` and `webpack/runtime/*` entries. Auto-discovers apps on macOS (`/Applications`, `~/Applications`) and Windows (`%LOCALAPPDATA%\Programs`, `%PROGRAMFILES%`, `%PROGRAMFILES(X86)%`, `%APPDATA%`); other platforms can pass `--asar <path>` explicitly. Safety: refuses to write to `/`, the user home, or the current working directory, and refuses non-empty existing output dirs without `--force`
+
+## 1.118.0 - 2026-05-21
+
+### Features
+- `codex-imagegen`: new image-generation backend for non-Codex runtimes (e.g., Claude Code) — spawns `codex exec --json --sandbox danger-full-access` and delegates to Codex CLI's built-in `image_gen` tool, so no `OPENAI_API_KEY` is required. Ships with idempotency cache, file-lock concurrency control, JSONL event-stream parsing, PNG magic-byte validation, and exponential-backoff retries (by @yelban, #158)
+- `baoyu-cover-image`: wire `SKILL.md` to call the `codex-imagegen` wrapper when `preferred_image_backend: codex-imagegen` is set, with `--timeout` documented for slow networks
+
+### Refactor
+- `codex-imagegen`: enforce `--prompt` / `--prompt-file` mutual exclusion in code (was docs-only)
+- `codex-imagegen`: replace `(opts as any).__promptFile` hack with a typed `promptFile` field on `CliOptions`
+- `codex-imagegen`: replace inline `cp|mv ... generated_images` regex with the shared `findCpToTarget` helper
+- `codex-imagegen`: propagate `attempts` on error responses (previously hardcoded to `0`)
+- `codex-imagegen`: drop dead `parseFinalJson()` + matching test (wrapper ignores agent-reported JSON in favor of disk verification)
+
+### Security
+- `codex-imagegen`: reject `--image` / `--ref` paths containing shell metacharacters before interpolating them into the agent instruction sent to `codex exec --sandbox danger-full-access`
+
+### Credits
+- `codex-imagegen` backend contributed by @yelban (#158)
+
+## 1.117.5 - 2026-05-21
+
+### Credits
+- `baoyu-post-to-wechat`: remote API publishing update credited to Dame5211 <1079825614@qq.com>
+
+## 1.117.4 - 2026-05-21
+
+### Features
+- `baoyu-post-to-wechat`: add remote API publishing via an SSH SOCKS5 tunnel
+
+### Fixes
+- `baoyu-post-to-wechat`: make remote API publishing work under Bun and strictly validate remote publish config
+
+### CI
+- Install `baoyu-post-to-wechat` script dependencies before running tests
+
+## 1.117.3 - 2026-05-20
+
+### Features
+- CI: add skill release commit validation — commits touching `skills/<name>/**` must use Conventional Commit subjects; SKILL.md version validated during publish/sync
+
+### Fixes
+- `baoyu-diagram`: add version field to SKILL.md
+- `baoyu-post-to-wechat`: sync SKILL.md version
+
+### Documentation
+- `baoyu-wechat-summary`: restructure profile fields — split `aliases` into `group_nicknames` (user's own prior names) and `aliases` (nicknames from other members), add `tags` for cross-cutting attributes
+
+## 1.117.2 - 2026-05-17
+
+### Documentation
+- `baoyu-cover-image`: ban programmatic text repair on generated bitmaps — disallow ImageMagick / Pillow / Canvas / SVG / HTML overlays to cover, rewrite, or replace title/subtitle text; regenerate from a corrected prompt or switch to a lower-text or no-title variant instead
+- `baoyu-article-illustrator`, `baoyu-comic`, `baoyu-image-cards`, `baoyu-xhs-images`, `baoyu-infographic`, `baoyu-slide-deck`: sync the same text-repair ban with skill-specific text categories (labels/captions, dialogue/sound effects, titles/body/tags, headings/data values, slide titles/bullets)
+
+## 1.117.1 - 2026-05-16
+
+### Fixes
+- `baoyu-post-to-wechat`: fix WeChat browser article publishing (by @zhangga)
+- `baoyu-post-to-wechat`: fix image upload fallback and WebP clipboard copy on macOS
+
+## 1.117.0 - 2026-05-16
+
+### Features
+- `baoyu-article-illustrator`: add batch generation policy — backend native batch first, runtime parallel calls second, sequential fallback; configurable `generation_batch_size` and `--batch-size` option
+- `baoyu-comic`: add batch generation policy with dependency-aware ordering (character sheet before pages) and configurable `--batch-size`
+- `baoyu-image-cards`: add batch generation policy honoring image-1 anchor chain, with configurable `--batch-size`
+- `baoyu-slide-deck`: add batch generation policy for slide image rendering with configurable `--batch-size`
+- `baoyu-xhs-images`: sync batch generation policy from baoyu-image-cards
+
+## 1.116.5 - 2026-05-14
+
+### Features
+- `baoyu-post-to-wechat`: send WeChat login QR code to Telegram when `TELEGRAM_BOT_TOKEN` and `TELEGRAM_CHAT_ID` env vars are set, enabling headless / remote login flows (by @beforesun)
+
+### Refactor
+- `baoyu-post-to-wechat`: harden Telegram QR notification — add 10s fetch timeout, defer the 2s QR-render wait until env vars are configured, and use viewport screenshot as fallback
+

 [English](./CHANGELOG.md) | 中文

+## 2.5.1 - 2026-06-13
+
+### 文档
+- 图片生成类 skills：在共享后端选择规则中补充 Cursor 原生 `GenerateImage` 后端说明，包括通过提示词声明宽高比、处理工具托管输出文件，以及使用 `reference_image_paths` 传入参考图。
+
+## 2.5.0 - 2026-06-12
+
+### 新功能
+- `baoyu-wechat-summary`：新增群级事实记忆（`memory.md`）。群友指正过、确认过的客观事实（如某个报错提示的真实原因、某产品名的正确写法）跨期生效——上一期摘要说错、被群友指正的说法，后续不再重犯。写入保守：三条门槛全满足才记（针对具体事实 + 有理由或证据 + 无人反驳），严格防注入（只记陈述句事实、不记对 bot 的行为指令，`@bot` 不是白名单通道），每条带出处，并有修订/作废/去重规则和 30 条上限。事实记忆由正常版和毒舌版共用
+- `baoyu-image-gen`：新增 Agnes AI 图片生成 provider (by @Davidlaizz)
+- `baoyu-image-gen`：默认使用 GA Gemini 图片端点，并支持搭配参考图使用 (by @hypn4)

+### 文档
+- 优化各 skill 的 description，提高触发准确度 (by @yanghaod2278827)
+- README：添加图书/电子书链接，并在技能列表中突出 `baoyu-design`
+
+## 2.4.1 - 2026-06-01
+
+### 修复
+- `baoyu-md` 与 `baoyu-chrome-cdp`：将 npm 包版本提升到 `0.1.1`，并刷新依赖它们的 skill 依赖约束与 lockfile，确保全新安装会拿到 Mermaid 子导出、打包的 `assets/mermaid.min.js`，以及 Markdown Mermaid 预处理导出。影响范围包括 `baoyu-markdown-to-html`、`baoyu-post-to-wechat`、`baoyu-post-to-weibo`、`baoyu-post-to-x`、`baoyu-danger-gemini-web`、`baoyu-danger-x-to-markdown`（[#172](https://github.com/JimLiu/baoyu-skills/issues/172)）
+
+## 2.4.0 - 2026-05-29
+
+### 新功能
+- `baoyu-wechat-summary`：为正常版和毒舌版简报新增「@bot 答疑」小节。识别群里提及 `@bot` / `@精华bot`（可通过新增的 `bot_aliases` 偏好自定义）的提问/请求，在专门小节中逐条回应——正常版真诚有用，毒舌版带刺但仍给干货。答复只依据群聊上下文和模型自有知识（不联网），需要实时数据的会如实注明
+
+## 2.3.0 - 2026-05-28

+### 文档
+- `baoyu-image-gen`：在 SKILL.md 的 Usage 段落中显式展示 `scripts/build-batch.ts`，使 `outline.md` + `prompts/` → `batch.json` 流程（例如 `baoyu-article-illustrator` 的产物）能与 `--batchfile` 并列被发现。明确 SKILL.md 中所有 `scripts/...` 路径均相对 `{baseDir}`，并把 Generation Mode 表中的指引改为 `{baseDir}/scripts/build-batch.ts`。`build-batch.ts --help` 同步打印 `bun` / `npx -y bun` 调用，与 skill 其它脚本统一使用 `{baseDir}/scripts/...` 写法
+
+## 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
+
+## 2.1.0 - 2026-05-24
+
+### 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
+
+## 2.0.1 - 2026-05-24
+
+### 修复
+- `baoyu-post-to-wechat`：发布 `newspic`（图文）时，将 `content` 字段从 HTML 转换为纯文本后再提交微信草稿接口。此前直接传 HTML，多图场景下内容长度超出限制会触发错误 45166（invalid content）。新增 `htmlToPlainText` 工具：把 `<br>` 和块级闭合标签转成换行、剥离其余标签、解码命名实体与十进制/十六进制数字实体、合并多余空白 (by @Go1dFinger, [#164](https://github.com/JimLiu/baoyu-skills/pull/164), 关联 [#163](https://github.com/JimLiu/baoyu-skills/issues/163))

+
+## 2.0.0 - 2026-05-24
+
+### 破坏性变更
+- 移除 `baoyu-imagine` skill。所有功能（providers、脚本、references）合并入 `baoyu-image-gen`，`marketplace.json` 改用新名称注册，`homepage` 链接更新为 `#baoyu-image-gen`
+- 移除 `baoyu-image-cards` skill。所有功能（样式、布局、配色、预设）合并入 `baoyu-xhs-images`，`marketplace.json` 改用新名称注册

+
+### 迁移说明
+- 旧的 `~/.baoyu-skills/baoyu-imagine/EXTEND.md` 与 `.baoyu-skills/baoyu-imagine/EXTEND.md` 配置文件会被 `scripts/main.ts` 中的 legacy-path 解析器自动重命名到 `…/baoyu-image-gen/EXTEND.md`，首次运行时迁移
+- 通过斜杠命令调用时，请将 `/baoyu-imagine ...` 改为 `/baoyu-image-gen ...`；将所有 `baoyu-image-cards` 改为 `baoyu-xhs-images`
+
+## 1.119.0 - 2026-05-24
+
+### 新功能
+- `baoyu-electron-extract`：新增 skill，可从任意已安装的 Electron 应用的 `app.asar` 中提取资源和 JavaScript。`.js.map` 文件内嵌 `sourcesContent` 时还原原始源码（含 TypeScript/JSX），否则用 Prettier 原地美化压缩后的 JS/CSS。source-map 路径先相对各 `.js.map` 文件解析，因此 `../../src/main.ts` 这类打包器相对路径会还原为 `restored/` 下的可读路径，而不是哈希占位符。始终跳过 `node_modules` 和 `webpack/runtime/*` 条目。macOS 下自动从 `/Applications` 和 `~/Applications` 发现应用，Windows 下从 `%LOCALAPPDATA%\Programs`、`%PROGRAMFILES%`、`%PROGRAMFILES(X86)%`、`%APPDATA%` 发现；其他平台请用 `--asar <path>` 显式指定。安全：拒绝写入 `/`、用户主目录或当前工作目录，未加 `--force` 时拒绝写入非空的已有输出目录
+
+## 1.118.0 - 2026-05-21
+
+### 新功能
+- `codex-imagegen`：新增面向非 Codex 运行时（如 Claude Code）的图像生成后端 —— 通过 `codex exec --json --sandbox danger-full-access` 调用 Codex CLI 内置的 `image_gen` 工具，无需 `OPENAI_API_KEY`。内置幂等缓存、文件锁并发控制、JSONL 事件流解析、PNG 魔术字节校验和指数退避重试 (by @yelban, #158)
+- `baoyu-cover-image`：在 `SKILL.md` 中接入 `codex-imagegen` 包装脚本（当 `preferred_image_backend: codex-imagegen` 时生效），并补充慢网络下的 `--timeout` 参数说明
+
+### 重构
+- `codex-imagegen`：在代码中强制校验 `--prompt` 与 `--prompt-file` 互斥（此前仅在文档说明）
+- `codex-imagegen`：将 `(opts as any).__promptFile` 这一 hack 改为 `CliOptions` 上类型化的 `promptFile` 字段
+- `codex-imagegen`：用复用的 `findCpToTarget` 辅助函数替换内联的 `cp|mv ... generated_images` 正则
+- `codex-imagegen`：错误返回时正确透传 `attempts`（此前硬编码为 `0`）
+- `codex-imagegen`：删除无用的 `parseFinalJson()` 函数及对应测试（包装脚本以磁盘校验为准，不再依赖 agent 自报 JSON）
+
+### 安全
+- `codex-imagegen`：在拼入发往 `codex exec --sandbox danger-full-access` 的 agent 指令前，拒绝包含 shell 元字符的 `--image` / `--ref` 路径

+Extract resources and JavaScript from any installed Electron app's `app.asar`. When `.js.map` files embed `sourcesContent`, restores the original source tree (TypeScript/JSX included); otherwise formats the minified JS/CSS with Prettier in place. Always skips `node_modules`. Works on macOS and Windows; pass `--asar <path>` on other platforms.

+# `codex-imagegen` Backend
+
+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 backend implements the `preferred_image_backend: codex-imagegen` config key already referenced in several `SKILL.md` files across this repo.
+
+## Features
+
+| Feature | Status |
+|---------|--------|
+| **Reliability**: retry + exponential backoff | Default 2 retries |
+| **Verification**: confirms `image_gen` was actually invoked (not bypassed) | Checks `$CODEX_HOME/generated_images/{thread_id}/` |
+| **Verification**: PNG magic-byte sanity check | ✓ |
+| **Idempotency cache**: reuses output for same prompt+aspect+refs | `--cache-dir` |
+| **Concurrency control**: file lock prevents parallel `codex exec` collisions | Built-in |
+| **Structured logging**: JSONL log file | `--log-file` |
+| **Token usage returned** | Embedded in result JSON |
+| **`--ref` reference images** | Repeatable |
+| **Unit tests** | 16 tests (parser / cache / validator) |
+| **Error classification**: retryable vs non-retryable | 9 `error_kind` values |
+
+## Why this backend
+
+| Scenario | Conventional backend | This backend |
+|----------|---------------------|--------------|
+| You have a Codex subscription | OpenAI Images API costs add up per image | Subscription already covers it — zero marginal API cost |
+| No `OPENAI_API_KEY` available | `baoyu-image-gen` needs an API key | `codex login` is enough |
+| Want to use GPT Image 2 | Only via OpenAI API | Codex's `image_gen` *is* GPT Image 2 |
+
+## Prerequisites
+
+```bash
+npm install -g @openai/codex
+codex login            # signs in with your OpenAI account (subscription)
+codex --version        # confirm >= 0.130
+```
+
+`bun` is required for running the wrapper. On macOS:
+
+```bash
+brew install oven-sh/bun/bun
+```
+
+If `bun` is not on `PATH`, fall back to `npx -y bun packages/baoyu-codex-imagegen/src/main.ts …`.
+
+## Usage
+
+### Direct CLI
+
+```bash
+# Inline prompt
+bun packages/baoyu-codex-imagegen/src/main.ts \
+  --image /tmp/cat.png \
+  --prompt "A friendly orange cat, watercolor"
+
+# Prompt from file
+bun packages/baoyu-codex-imagegen/src/main.ts \
+  --image cover.png \
+  --prompt-file prompts/01-cover.md \
+  --aspect 16:9
+
+# Verbose mode for debugging
+bun packages/baoyu-codex-imagegen/src/main.ts -v --image dog.png --prompt "A corgi" --aspect 1:1
+```
+
+### Through `baoyu-image-gen`
+
+```bash
+${BUN_X} skills/baoyu-image-gen/scripts/main.ts \
+  --provider codex-cli \
+  --prompt "A friendly orange cat, watercolor" \
+  --image /tmp/cat.png \
+  --ar 1:1
+```
+
+The `codex-cli` provider spawns the bundled `codex-imagegen` TS entrypoint internally and surfaces its retry/cache machinery through baoyu-image-gen's standard CLI + batch flow.
+
+On success, stdout emits a single JSON line:
+
+```json
+{"status":"ok","path":"/tmp/cat.png","bytes":2567101,"elapsed_seconds":53}
+```
+
+On failure, exit code is non-zero and stderr contains the error message.

+Image-generating skills (e.g., `baoyu-cover-image`, `baoyu-article-illustrator`) already support a `preferred_image_backend` preference. To route them through this backend, set the following in the corresponding `EXTEND.md`:
+
+```yaml
+# ~/.baoyu-skills/baoyu-cover-image/EXTEND.md
+preferred_image_backend: codex-imagegen
+```
+
+When the LLM runs the skill, it reads the preference and — guided by the `### codex-imagegen Backend` section in `CLAUDE.md` — invokes `bun packages/baoyu-codex-imagegen/src/main.ts`.
+
+> **Note**: The integration is mediated by the LLM reading `CLAUDE.md`. It is not a hard binding. If a skill does not route to the backend automatically, mentioning it explicitly in the prompt works.
+
+## Parameters
+
+| Flag | Required | Description |
+|------|----------|-------------|
+| `--image <path>` | ✓ | Output PNG path (absolute recommended; relative paths are resolved against cwd) |
+| `--prompt <text>` | one of | Prompt string (mutually exclusive with `--prompt-file`) |
+| `--prompt-file <path>` | one of | Read prompt from file (mutually exclusive with `--prompt`) |
+| `--aspect <ratio>` | | Aspect ratio. Default `1:1`. Common: `16:9`, `9:16`, `4:3`, `2.35:1` |
+| `--ref <file>` | | Reference image path (repeatable) |
+| `--timeout <ms>` | | `codex exec` timeout in ms. Default `300000` |
+| `--retries <n>` | | Retry count on retryable errors. Default `2` (total attempts = retries + 1) |
+| `--retry-delay <ms>` | | Base delay between retries (exponential backoff). Default `1500` |
+| `--cache-dir <path>` | | Enable idempotency cache (reuses output for same prompt+aspect+refs) |
+| `--log-file <path>` | | Structured JSONL log path (appended) |
+| `-v` / `--verbose` | | Mirror log entries to stderr |
+| `-h` / `--help` | | Show usage |
+
+## Structured Output
+
+On success, stdout contains a single JSON line:
+
+```json
+{
+  "status": "ok",
+  "path": "/tmp/owl.png",
+  "bytes": 1693831,
+  "elapsed_seconds": 87,
+  "thread_id": "019e40e8-daef-7c60-943d-5e7bb3f6cb3d",
+  "attempts": 1,
+  "cached": false,
+  "usage": {
+    "input": 110899,
+    "cached_input": 83456,
+    "output": 457,
+    "reasoning": 47
+  },
+  "tool_calls": [
+    {"tool": "shell", "status": "completed"},
+    {"tool": "agent_message", "status": "completed"}
+  ]
+}
+```
+
+Cache hits return with `elapsed_seconds: 0`, `cached: true`, `attempts: 0`.
+
+On failure, exit code is `1` and the JSON contains `error` and `error_kind`:
+
+```json
+{
+  "status": "error",
+  "error": "image_gen was not invoked: no PNG in ...",
+  "error_kind": "no_image_gen_tool_use"
+}
+```
+
+## Error Kinds
+
+| `error_kind` | Retryable | Meaning |
+|--------------|-----------|---------|
+| `codex_not_installed` | ✗ | `codex` CLI not found |
+| `invalid_args` | ✗ | Argument parsing error |
+| `prompt_file_missing` | ✗ | `--prompt-file` path does not exist |
+| `spawn_failed` | ✓ | `codex exec` exited non-zero |
+| `timeout` | ✓ | Exceeded `--timeout` |
+| `no_image_gen_tool_use` | ✓ | Agent did not invoke `image_gen` (it took another path) |
+| `output_missing` | ✓ | Output file not created |
+| `invalid_png` | ✓ | Output is not a valid PNG |
+| `agent_refused` | ✓ | No `thread_id` in event stream (Codex refused to respond) |
+| `lock_busy` | ✗ | Concurrency lock acquisition timed out |
+
+## Measured Performance
+
+| Metric | Value |
+|--------|-------|
+| First-run latency | 50–90 s |
+| Cache-hit latency | < 0.3 s |
+| Output dimensions | 1024×1024, 1672×941 (16:9), etc. — chosen by `image_gen` |
+| Output format | PNG (RGB, 8-bit) |
+| Token usage per call | ~110k input (~80k cached) + ~500 output |
+| Quota source | Codex subscription (does not consume OpenAI API quota) |
+| Default timeout | 300 s (5 min) |
+
+## Limitations & Risks
+
+1. **5–10× slower than direct API**. `codex exec` cold-starts the agent, loads the built-in `image_gen` SKILL.md, and runs reasoning before invoking the tool. Cache hits avoid this for repeated prompts.
+2. **ToS gray area**. Codex's `image_gen` tool is designed for interactive use. Invoking it programmatically via `codex exec` from an external agent is not explicitly addressed by current OpenAI policies. Suggested guardrails:
+   - Personal, low-volume use is reasonable.
+   - Not recommended for production automation or high-volume batch jobs.
+   - Users are responsible for ensuring their usage complies with applicable terms of service.
+3. **Sandbox permissions**. The wrapper passes `--sandbox danger-full-access` so the spawned agent can move the rendered PNG out of `$CODEX_HOME/generated_images/`. This is necessary because the agent must `cp`/`mv` the file to the user-specified output path.
+4. **Concurrency = 1**. The file lock serializes concurrent invocations to avoid `codex exec` collisions. Parallel calls queue.
+
+## Troubleshooting
+
+| Symptom | `error_kind` | Resolution |
+|---------|--------------|------------|
+| `command not found: codex` | `codex_not_installed` | `npm install -g @openai/codex` |
+| `codex exec` fails | `spawn_failed` | Check `codex login` status; inspect `raw_log` path |
+| Timeout | `timeout` | Pass `--timeout 600000` (10 min) for slow networks |
+| Agent skipped `image_gen` | `no_image_gen_tool_use` | Auto-retries; consider sharpening the prompt — abstract prompts let the agent wander |
+| Output missing | `output_missing` | Agent did not `cp` to the target path; check `raw_log` for the actual save location under `generated_images/` |
+| Lock held | `lock_busy` | Wait for the in-flight request to finish; or `rm ~/.cache/baoyu-codex-imagegen/codex-exec.lock` |
+| Low image quality | — | Sharpen the prompt, try a different aspect, or supply `--ref` |

+
+## Design Decisions
+
+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. **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.

 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).

Reference images go in `reference_image_paths`.

+# 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.

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-imagine`), use it.
+   - 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.
 4. **If none are available**, tell the user and ask how to proceed.

 **⛔ Never substitute SVG, HTML, canvas, or other code-based rendering for raster image generation.** Codex `imagegen`'s own description says it should be used "when the output should be a bitmap asset rather than repo-native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do **not** silently emit SVG, write inline `<svg>` markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram-like": the consumer skill calling this rule has already decided that a raster image is what it needs.

+**⛔ Never repair rendered text by painting over a generated bitmap.** Do not use ImageMagick, Pillow, Canvas, SVG, HTML/CSS, OCR scripts, or any other programmatic overlay to cover, rewrite, erase, stroke, or replace labels, captions, or any other text inside an already generated illustration. If text is wrong or unclear, regenerate from a corrected prompt, redraw with less or no on-image text, or ask the user which imperfect candidate to keep.
+
 Setting `preferred_image_backend: ask` forces the step-3 prompt every run regardless of available backends. Users change the pinned backend via the `## Changing Preferences` section below.

 **Prompt file requirement (hard)**: write each image's full, final prompt to a standalone file under `prompts/` (naming: `NN-{type}-[slug].md`) BEFORE invoking any backend. The backend receives the prompt file (or its content); the file is the reproducibility record and lets you switch backends without regenerating prompts.

+## Batch Generation Policy
+
+After every prompt file for the run has been saved and verified, generate images in batches by default.
+
+Priority order:
+
+1. Use the chosen backend's native batch / multi-task interface if it exists. Each task must keep its own prompt file, output path, aspect ratio, and direct reference images.
+2. If no native batch interface exists but the runtime can issue parallel tool calls, dispatch up to `generation_batch_size` images at a time. Default: `4`. An explicit user request in the current message, such as `--batch-size 4` or "并行4张一起生成", overrides EXTEND.md.
+3. If neither native batch nor parallel tool calls are available, generate sequentially.
+
+Rules:
+
+- Never start the first batch until all prompt files for that batch exist on disk.
+- Retry failed items once without regenerating successful items.
+- Do not use subagents merely to parallelize image rendering. Use subagents only for separate prompt iteration or creative exploration.

+# `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
+${BUN_X} <baoyu-image-gen-base>/scripts/main.ts \
+  --provider codex-cli \
+  --image <ABSOLUTE_output> \
+  --promptfiles <ABSOLUTE_prompts/NN-{type}-{slug}.md> \
+  --ar <ratio> \
+  [--ref <ABSOLUTE_file>]...
+```
+
+Resolve `<baoyu-image-gen-base>` the same way you resolve any sibling skill — through your runtime's skill registry (`Skill` tool, plugin marketplace, or `$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/NN-{type}-{slug}.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`.

 4. **If none are available**, tell the user and ask how to proceed.

 **⛔ Never substitute SVG, HTML, canvas, or other code-based rendering for raster image generation.** Codex `imagegen`'s own description says it should be used "when the output should be a bitmap asset rather than repo-native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do **not** silently emit SVG, write inline `<svg>` markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram-like": the consumer skill calling this rule has already decided that a raster image is what it needs.

+**⛔ Never repair rendered text by painting over a generated bitmap.** Do not use ImageMagick, Pillow, Canvas, SVG, HTML/CSS, OCR scripts, or any other programmatic overlay to cover, rewrite, erase, stroke, or replace dialogue, sound effects, panel labels, or any other text inside an already generated comic page. If text is wrong or unclear, regenerate from a corrected prompt, redraw the page with less or no on-image text, or ask the user which imperfect candidate to keep.
+
 Setting `preferred_image_backend: ask` forces the step-3 prompt every run regardless of available backends. Users change the pinned backend via the `## Changing Preferences` section below.

 **Prompt file requirement (hard)**: write each image's full, final prompt to a standalone file under `prompts/` (naming: `NN-{type}-[slug].md`) BEFORE invoking any backend. The backend receives the prompt file (or its content); the file is the reproducibility record and lets you switch backends without regenerating prompts.

+
+## Batch Generation Policy
+
+After every prompt file for the current generation group has been saved and verified, generate images in batches by default.
+
+Priority order:
+
+1. Use the chosen backend's native batch / multi-task interface if it exists. Each task must keep its own prompt file, output path, aspect ratio, session ID, and direct reference images.
+2. If no native batch interface exists but the runtime can issue parallel tool calls, dispatch up to `generation_batch_size` images at a time. Default: `4`. An explicit user request in the current message, such as `--batch-size 4` or "并行4张一起生成", overrides EXTEND.md.
+3. If neither native batch nor parallel tool calls are available, generate sequentially.
+
+Rules:
+
+- Honor workflow dependencies first: generate `characters/characters.png` before pages that use it as a reference.
+- Never start the first page batch until all selected page prompt files exist on disk.
+- Retry failed items once without regenerating successful items.
+- Do not use subagents merely to parallelize image rendering. Use subagents only for separate prompt iteration or creative exploration.

+# `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
+${BUN_X} <baoyu-image-gen-base>/scripts/main.ts \
+  --provider codex-cli \
+  --image <ABSOLUTE_output> \
+  --promptfiles <ABSOLUTE_prompts/NN-{cover|page}-[slug].md> \
+  --ar <ratio> \
+  [--ref <ABSOLUTE_file>]...
+```
+
+Resolve `<baoyu-image-gen-base>` the same way you resolve any sibling skill — through your runtime's skill registry (`Skill` tool, plugin marketplace, or `$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/NN-{cover|page}-[slug].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`.

+```
+
+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/01-cover-[slug].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`.

+# Electron App Extract
+
+Extracts resources and code from an installed Electron app's `app.asar`. When a `.js.map` is present, restores the original source files from the embedded `sourcesContent`; otherwise formats the minified code with Prettier. Source-map paths are resolved relative to the `.js.map` file first, so bundled paths like `../../src/main.ts` restore to readable paths such as `restored/src/main.ts` instead of hashed placeholders. Always skips `node_modules`. Works on macOS and Windows.
+
+## User Input Tools
+
+When this skill prompts the user, follow this tool-selection rule (priority order):
+
+1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
+2. **Fallback**: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
+3. **Batching**: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.
+
+Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes.
+
+## Script Directory
+
+Scripts in `scripts/` subdirectory. `{baseDir}` = this SKILL.md's directory path. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun. Replace `{baseDir}` and `${BUN_X}` with actual values.
+
+| Script            | Purpose                                                                        |
+| ----------------- | ------------------------------------------------------------------------------ |
+| `scripts/main.ts` | App discovery + asar extraction + source-map restoration + Prettier formatting |
+
+## When to use
+
+Use this skill whenever the user wants to look inside an installed Electron application or inspect its bundled code. Trigger phrases include:
+
+- "extract Electron app", "decompile this Electron app", "unpack app.asar"
+- "show me the source of <app>", "look inside <app>", "how is <app> built"
+- "get the source code of Codex / Cursor / Discord / Slack / VS Code / Notion / Obsidian / ChatGPT desktop"
+- "提取 Electron 应用", "看 <app> 的源码", "反编译 Electron", "解包 app.asar", "还原 source map"
+
+Both **app name** (e.g., `Codex`) and **absolute path** (e.g., `/Applications/Codex.app`, a `.asar` file, or a Windows install dir) are accepted. The script handles discovery for both platforms.
+
+## Workflow
+
+**1. Determine the input.** Ask the user for the app name or path if they haven't given one. If they want a custom output directory, ask for that too.
+
+**2. Run the script.**
+
+```bash
+${BUN_X} {baseDir}/scripts/main.ts "<app>" [--output <dir>] [--asar <path>] [--force]
+```
+
+Start with `--dry-run` first if you're unsure whether discovery will find the right bundle — it prints the resolved paths and exits without touching the filesystem.
+
+**3. Handle the result.**
+
+- **Success** → report the output paths and the counts (extracted / restored / formatted).
+- **Multiple matches** → the script lists candidates and exits non-zero. Show the user the candidates, ask which one to use (via `AskUserQuestion` or the runtime equivalent), then re-run with the chosen absolute path.
+- **Existing non-empty output dir** → the script refuses without `--force`. Ask the user whether to overwrite (`--force`) or pick a new `--output` path.
+- **Unsupported platform / no match** → suggest passing `--asar /full/path/to/app.asar` if the user knows where the bundle lives.
+
+**4. Point the user at the result.** The default output dir is `~/Downloads/<AppName>-electron-extract/`. The most interesting subdirectory depends on what was found:
+
+- `restored/` exists → the original source tree was reconstructed from `.js.map` files; this is what to read first.
+- Only `extracted/` exists (no maps) → the JS/CSS in `extracted/` was Prettier-formatted in place; read from there.
+
+## Source-map path restoration
+
+The script should preserve original source names and directory structure as much as the source map allows:
+
+- Resolve each `sources[]` entry with `sourceRoot` when present, then relative to the `.js.map` file's directory inside `extracted/`.
+- Collapse normal bundler-relative paths into the restored project tree. For example, `.vite/main/index.js.map` + `../../src/main.ts` becomes `restored/src/main.ts`.
+- If a source path climbs above `extracted/`, keep the readable remaining path under `restored/` instead of hashing it. For example, `.vite/main/index.js.map` + `../../../shared/src/lib/foo.ts` becomes `restored/shared/src/lib/foo.ts`.
+- Strip URL/query decorations from source names, including common `webpack://`, `file://`, and `?loader` suffixes.
+- Use `restored/__unknown/<hash>.<ext>` only when the source name is empty or cannot be reduced to a safe file path.
+- Continue skipping `node_modules` and `webpack/runtime/*` entries; these are bundler/runtime noise, not app sources.
+
+## Usage
+
+```bash
+# Extract by app name (default output: ~/Downloads/Codex-electron-extract/)
+${BUN_X} {baseDir}/scripts/main.ts Codex
+
+# Extract by absolute path (works for .app bundles, install dirs, or .asar files)
+${BUN_X} {baseDir}/scripts/main.ts "/Applications/Visual Studio Code.app"
+${BUN_X} {baseDir}/scripts/main.ts "C:\Users\you\AppData\Local\Programs\codex"
+${BUN_X} {baseDir}/scripts/main.ts --asar /Applications/Codex.app/Contents/Resources/app.asar Codex
+
+# Custom output
+${BUN_X} {baseDir}/scripts/main.ts Codex --output ~/work/codex-source
+
+# Preview discovery without writing anything
+${BUN_X} {baseDir}/scripts/main.ts Codex --dry-run
+
+# Overwrite an existing output dir
+${BUN_X} {baseDir}/scripts/main.ts Codex --force
+
+# Machine-readable result (one JSON line on stdout)
+${BUN_X} {baseDir}/scripts/main.ts Codex --json

+
+## Notes
+
+- **node_modules** is always skipped — both for source-map restoration and Prettier formatting — because vendored dependencies are noise when inspecting an app.
+- **Source-map restoration** only works when the `.js.map` embeds `sourcesContent`. This is the common case for modern bundlers (webpack, esbuild, Vite, rollup). If a map references external `.ts`/`.js` files without embedding them, that map is skipped and the corresponding `.js` is Prettier-formatted instead. Skipped maps are listed in `extract-report.json` under `warnings`.
+- **Readable paths over hashes** — don't treat `../` segments in source-map paths as automatically unsafe. First resolve them from the map location and then sanitize the final output path so it still stays under `restored/`. Hash fallback is only for unusable source names.
+- **App discovery** searches `/Applications` + `~/Applications` on macOS, and `%LOCALAPPDATA%\Programs`, `%PROGRAMFILES%`, `%PROGRAMFILES(X86)%`, `%APPDATA%` on Windows. If discovery finds multiple matches, the script exits and lists them — re-run with an absolute path. On Linux or other platforms, pass `--asar /path/to/app.asar` explicitly.
+- **Safety** — the script refuses to write to `/`, the user home directly, or the current working directory, and refuses to populate an existing non-empty output dir without `--force`.
+- **No global installs** — `@electron/asar` and `prettier` are resolved on-the-fly via `npx -y`. First run will be slower while npx caches them.

-
-# Image Card Series Generator
-
-Break down complex content into eye-catching image card series with multiple style options.
-
-## User Input Tools
-
-When this skill prompts the user, follow this tool-selection rule (priority order):
-
-1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
-2. **Fallback**: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
-3. **Batching**: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.
-
-Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes.
-
-## Image Generation Tools
-
-When this skill needs to render an image, resolve the backend in this order:
-
-1. **Current-request override** — if the user names a specific backend in the current message, use it.
-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-imagine`) unless the user has explicitly pinned a different `preferred_image_backend`.
-   - **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-imagine`), use it.
-   - Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.
-4. **If none are available**, tell the user and ask how to proceed.
-
-**⛔ Never substitute SVG, HTML, canvas, or other code-based rendering for raster image generation.** Codex `imagegen`'s own description says it should be used "when the output should be a bitmap asset rather than repo-native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do **not** silently emit SVG, write inline `<svg>` markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram-like": the consumer skill calling this rule has already decided that a raster image is what it needs.
-
-Setting `preferred_image_backend: ask` forces the step-3 prompt every run regardless of available backends. Users change the pinned backend via the `## Changing Preferences` section below.
-
-**Prompt file requirement (hard)**: write each image's full, final prompt to a standalone file under `prompts/` (naming: `NN-{type}-[slug].md`) BEFORE invoking any backend. The file is the reproducibility record and lets you switch backends without regenerating prompts.
-
-Concrete tool names (`imagegen`, `image_generate`, `baoyu-imagine`) above are examples — substitute the local equivalents under the same rule.
-
-## Confirmation Policy
-
-Default behavior: **confirm before generation**.
-
- Treat explicit skill invocation, a file path, matched signals/presets, and `EXTEND.md` defaults as **recommendation inputs only**. None of them authorizes skipping confirmation.
- Do **not** start Step 3 until the user completes Step 2.
- Skip confirmation only when the current request explicitly says to do so, for example: `--yes`, "直接生成", "不用确认", "跳过确认", "按默认出图", or equivalent wording.
- If confirmation is skipped explicitly, state the assumed strategy / style / layout / palette / count / backend in the next user-facing update before generating.
-
-## Language
-
-Respond in the user's language across questions, progress, errors, and completion summary. Keep technical tokens (style names, file paths, code) in English.
-
-## Options
-
-| Option | Description |
-|--------|-------------|
-| `--style <name>` | Visual style (see Styles below) |
-| `--layout <name>` | Information layout (see Layouts below) |
-| `--palette <name>` | Color override: macaron / warm / neon |
-| `--preset <name>` | Style + layout + optional palette shorthand (see Presets below; per-preset prompt fragments in `references/style-presets.md`) |
-| `--ref <files...>` | Reference images applied to image 1 as the series anchor |
-| `--yes` | Non-interactive: skip all confirmations, use EXTEND.md or built-in defaults, auto-confirm recommended plan (Path A) |
-
-## Dimensions
-
-Three independent knobs combine freely:
-
-| Dimension | Controls | Options |
-|-----------|----------|---------|
-| **Style** | Visual aesthetics (lines, decorations, rendering) | 12 styles (see Styles below) |
-| **Layout** | Information structure (density, arrangement) | 8 layouts (see Layouts below) |
-| **Palette** (optional) | Color override, replaces the style's default colors | macaron / warm / neon (see Palettes below) |
-
-Example: `--style notion --layout dense` makes an intellectual knowledge card; add `--palette macaron` to soften the colors without changing notion's rendering rules. A `--preset` is a shorthand for style + layout (+ optional palette).
-
-**Palette behavior**: no `--palette` → style's built-in colors; `--palette <name>` → overrides colors only, rendering rules unchanged. Some styles declare a `default_palette` (e.g., sketch-notes defaults to macaron).
-
-## Styles (12)

-## Outline Strategies
-
-Three differentiated approaches — each produces a structurally different outline. The workflow recommends one; Path C generates all three and lets the user choose.
-
-| Strategy | Concept | Best for | Structure |
-|----------|---------|----------|-----------|
-| **A — Story-Driven** | Personal experience as the thread, emotional resonance first | Reviews, personal shares, transformation | Hook → Problem → Discovery → Experience → Conclusion |

-
-## Reference Images
-
-User-supplied refs are **separate from** the internal "image-1 as anchor" chain (Step 3) — they layer on top of it.
-
-**Intake**: via `--ref <files...>` or paths pasted in conversation.
- File path → copy to `refs/NN-ref-{slug}.{ext}`
- Pasted with no path → ask for the path, or extract style traits as a text fallback
-
-**Usage modes** (per reference):
-
-| Usage | Effect |
-|-------|--------|
-| `direct` | Pass the file to the backend (typically on image 1 only, so the anchor propagates through the chain) |
-| `style` | Extract style traits and append to every card's prompt body |
-| `palette` | Extract hex colors and append to every card's prompt body |
-
-Record refs in each affected card's prompt frontmatter:
-
-```yaml
-references:
-  - ref_id: 01
-    filename: 01-ref-brand.png
-    usage: direct
-```
-
-At generation time: verify files exist. Image 1 with `usage: direct` + backend that accepts refs → pass via the backend's ref parameter (becomes the chain anchor). Images 2+ keep using image-1 as `--ref` per Step 3 — do NOT re-stack user refs on top (avoids conflicting signals). For `style`/`palette`, embed extracted traits in every prompt.
-
-## File Layout
-
-```
-image-cards/{topic-slug}/
-├── source-{slug}.{ext}
-├── analysis.md
-├── outline-strategy-{a,b,c}.md    # Path C only
-├── outline.md
-├── prompts/NN-{type}-{slug}.md
-├── NN-{type}-{slug}.png
-└── refs/                          # only if --ref used
-```
-
-**Slug**: 2-4 words, kebab-case. "AI 工具推荐" → `ai-tools-recommend`. On collision, append `-YYYYMMDD-HHMMSS`.
-
-**Backup rule** (applies throughout): before overwriting any file — source, outline, prompt, image — rename the existing one to `<name>-backup-YYYYMMDD-HHMMSS.<ext>`. This protects user edits.
-
-## Workflow
-
-```
- [ ] Step 0: Load EXTEND.md ⛔ BLOCKING (interactive only)
- [ ] Step 1: Analyze content → analysis.md
- [ ] Step 2: Smart Confirm ⚠️ REQUIRED (Path A / B / C)
- [ ] Step 3: Generate images
- [ ] Step 4: Completion report
-```
-
-### Step 0: Load EXTEND.md ⛔ BLOCKING
-
-Check these paths in order; first hit wins:
-
-| Path | Scope |
-|------|-------|
-| `.baoyu-skills/baoyu-image-cards/EXTEND.md` | Project |
-| `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-image-cards/EXTEND.md` | XDG |
-| `$HOME/.baoyu-skills/baoyu-image-cards/EXTEND.md` | User home |
-
- **Found** → read, parse, print a summary (style / layout / watermark / language), continue.
- **Not found + interactive** → run first-time setup (see `references/config/first-time-setup.md`) and save before anything else. Do NOT analyze content or ask style questions until preferences exist — this keeps first-run behavior predictable.
- **Not found + `--yes`** → skip setup, use built-in defaults (no watermark, style/layout auto-selected, language from content). Do not prompt, do not create EXTEND.md.
-
-**EXTEND.md keys**: watermark, preferred style/layout, custom style definitions, language preference. Schema: `references/config/preferences-schema.md`.
-
-### Step 1: Analyze Content → `analysis.md`
-
-1. Save the source (backup rule applies if `source.md` exists).
-2. Run the deep analysis in `references/workflows/analysis-framework.md`: content type, hook potential, audience, engagement signals, visual opportunity map, swipe flow.
-3. Detect source language, pick recommended image count (2-10).
-4. Auto-recommend strategy + style + layout + palette using the **Auto-Selection** table above.
-5. Write everything to `analysis.md`.
-
-### Step 2: Smart Confirm ⚠️ REQUIRED
-
-**Hard gate**: this step is mandatory per the [Confirmation Policy](#confirmation-policy) — Step 3 cannot start until the user confirms here (or explicitly opts out with `--yes` / equivalent wording in the current request).
-
-Goal: present the auto-recommended plan and let the user confirm or adjust. Skip this step entirely under `--yes` — proceed with Path A using the analysis and any CLI overrides.
-
-**Display summary** before asking:
-
-```
-📋 内容分析
-  主题：[topic] | 类型：[content_type]
-  要点：[key points]
-  受众：[audience]
-
-🎨 推荐方案（自动匹配）
-  策略：[A/B/C] [name]（[reason]）
-  风格：[style] · 布局：[layout] · 配色：[palette or 默认] · 预设：[preset]
-  图片：[N]张（封面+[N-2]内容+结尾）
-  元素：[background] / [decorations] / [emphasis]
-```
-
-Then ask one question — three paths. Verbatim option copy: `references/confirmation.md`.
-
-**Path A — Quick confirm** (trust auto-recommendation): generate a single outline using the recommended strategy + style → save to `outline.md` → Step 3.
-
-**Path B — Customize**: ask five questions (strategy/style, layout, palette, count, optional notes) with the recommendation pre-filled — blanks keep the recommendation. Generate one outline with the user's choices → `outline.md` → Step 3. See `references/confirmation.md`.
-
-**Path C — Detailed mode**: two sub-confirmations.
-
- *Step 2a — Content understanding*: ask selling points (multi-select), audience, style preference (authentic / professional / aesthetic / auto), optional context. Update `analysis.md`.
- *Step 2b — Three outline variants*: generate `outline-strategy-a.md`, `outline-strategy-b.md`, `outline-strategy-c.md`. Each MUST have a different structure AND a different recommended style — include `style_reason` in the frontmatter. Page-count heuristic: A ~4-6, B ~3-5, C ~3-4. Template: `references/workflows/outline-template.md`; frontmatter example in `references/confirmation.md`.
- *Step 2c — Selection*: ask three questions (outline A/B/C/Combined, style, visual elements). Save selected/merged outline to `outline.md` → Step 3.
-
-### Step 3: Generate Images
-
-With confirmed outline + style + layout + palette:
-
-**Visual consistency — image-1 anchor chain**: character / mascot / color rendering drifts between calls unless you anchor them. Generate image 1 (cover) first WITHOUT `--ref`, then pass image 1 as `--ref` to every subsequent image. This is the single most important consistency trick for this skill — don't skip it even if the backend also supports a session ID.
-
-For each image (cover, content, ending):
-
-1. Write the full prompt to `prompts/NN-{type}-{slug}.md` in the user's preferred language (backup rule applies).
-2. Generate:
-   - **Image 1**: no `--ref` (establishes the anchor).
-   - **Images 2+**: add `--ref <path-to-image-01.png>`.
-   - Backup rule applies to the PNG files.
-3. Report progress after each image.
-
-**Watermark** (if enabled in EXTEND.md): append to the generation prompt:
-
-```
-Include a subtle watermark "[content]" positioned at [position].
-The watermark should be legible but not distracting.
-```
-
-See `references/config/watermark-guide.md`.
-
-**Backend selection**: per the Image Generation Tools rule at the top — use whatever is available, ask once if multiple, before any generation. Under `--yes`, use the EXTEND.md preference and fall back to the first available backend. Prompt files MUST exist before invoking any backend.
-
-**Session ID** (if the backend supports `--sessionId`): use `cards-{topic-slug}-{timestamp}` for every image; combined with the ref chain this gives maximum consistency.
-
-### Step 4: Completion Report
-
-```
-Image Card Series Complete!
-
-Topic: [topic]
-Mode: [Quick / Custom / Detailed]
-Strategy: [A/B/C/Combined]
-Style: [name]
-Palette: [name or "default"]
-Layout: [name or "varies"]
-Location: [directory]
-Images: N total
-
-✓ analysis.md
-✓ outline.md
-✓ outline-strategy-a/b/c.md (detailed mode only)
-
- 01-cover-[slug].png ✓ Cover (sparse)
- 02-content-[slug].png ✓ Content (balanced)
- ...
- NN-ending-[slug].png ✓ Ending (sparse)
-```
-
-## Content Breakdown Principles
-
-| Position | Purpose | Typical layout |
-|----------|---------|----------------|
-| Cover (image 1) | Hook + visual impact | `sparse` |
-| Content (middle) | Core value per image | `balanced` / `dense` / `list` / `comparison` / `flow` |
-| Ending (last) | CTA / summary | `sparse` or `balanced` |
-
-For the style × layout compatibility matrix, see the **Style × Layout Matrix** above.
-
-## Image Modification
-
-| Action | How |
-|--------|-----|
-| Edit | Update `prompts/NN-{type}-{slug}.md` **first**, then regenerate with the same session ID |
-| Add | Specify position, create prompt, generate, renumber subsequent files `NN+1`, update outline |
-| Delete | Remove files, renumber subsequent `NN-1`, update outline |
-
-Always update the prompt file before regenerating — it's the source of truth and makes changes reproducible.

-
- Auto-retry once on generation failure before reporting an error.
- For sensitive public figures, use stylized cartoon alternatives.
- Smart Confirm (Step 2) is required; Detailed mode adds a second confirmation (2a + 2c).
-
-## Changing Preferences
-
-EXTEND.md lives at the first matching path listed in Step 0. Three ways to change it:
-
- **Edit directly** — open EXTEND.md and change fields. Full schema: `references/config/preferences-schema.md`.
- **Reconfigure interactively** — delete EXTEND.md (or ask "reconfigure baoyu-image-cards preferences" / "重新配置"). The next run re-triggers first-time setup.
- **Common one-line edits**:
-  - `preferred_image_backend: auto` — default; runtime-native tool wins, falls back to the only installed backend, asks only if multiple non-native are present.
-  - `preferred_image_backend: codex-imagegen` — pin to Codex's built-in.
-  - `preferred_image_backend: baoyu-imagine` — pin to the baoyu-imagine skill.
-  - `preferred_image_backend: ask` — confirm backend every run.
-  - `preferred_style: notion`, `preferred_layout: dense`, `preferred_palette: macaron`, `language: zh`.
-  - `watermark.enabled: true` + `watermark.content: "@handle"` — add a watermark.

-# First-Time Setup
-
-## Overview
-
-When no EXTEND.md is found, guide user through preference setup.
-
-**⛔ BLOCKING OPERATION**: This setup MUST complete before ANY other workflow steps. Do NOT:
- Ask about content/article
- Ask about style or layout
- Ask about target audience
- Proceed to content analysis
-
-ONLY ask the questions in this setup flow, save EXTEND.md, then continue.
-
-## Setup Flow
-
-```
-No EXTEND.md found

-
-## Questions
-
-**Language**: Use user's input language or saved language preference.
-
-Use single AskUserQuestion with multiple questions (AskUserQuestion auto-adds "Other" option):
-
-### Question 1: Watermark
-
-```
-header: "Watermark"
-question: "Watermark text for generated images? Type your watermark content (e.g., name, @handle)"
-options:
-  - label: "No watermark (Recommended)"
-    description: "No watermark, can enable later in EXTEND.md"
-```
-
-Position defaults to bottom-right.
-
-### Question 2: Preferred Style
-
-```
-header: "Style"
-question: "Default visual style preference? Or type another style name or your custom style"
-options:
-  - label: "None (Recommended)"
-    description: "Auto-select based on content analysis"
-  - label: "cute"
-    description: "Sweet, adorable - classic XHS aesthetic"
-  - label: "notion"
-    description: "Minimalist hand-drawn, intellectual"
-```
-
-### Question 3: Save Location
-
-```
-header: "Save"
-question: "Where to save preferences?"
-options:
-  - label: "Project"
-    description: ".baoyu-skills/ (this project only)"
-  - label: "User"
-    description: "~/.baoyu-skills/ (all projects)"
-```
-
-## Save Locations
-
-| Choice | Path | Scope |
-|--------|------|-------|
-| Project | `.baoyu-skills/baoyu-xhs-images/EXTEND.md` | Current project |
-| User | `~/.baoyu-skills/baoyu-xhs-images/EXTEND.md` | All projects |
-
-## After Setup
-
-1. Create directory if needed
-2. Write EXTEND.md with frontmatter
-3. Confirm: "Preferences saved to [path]"
-4. Continue to Step 1
-
-## EXTEND.md Template
-
-```yaml
---
-version: 1
-watermark:
-  enabled: [true/false]
-  content: "[user input or empty]"
-  position: bottom-right
-  opacity: 0.7
-preferred_style:
-  name: [selected style or null]
-  description: ""
-preferred_layout: null
-language: null
-preferred_image_backend: auto
-custom_styles: []
---
-```
-
-`preferred_image_backend: auto` is the baked-in default — first-time setup does not ask about it. The `## Image Generation Tools` rule in SKILL.md then picks the runtime-native tool (Codex `imagegen`, Hermes `image_generate`, etc.) when available, and falls back to installed backends.
-
-## Modifying Preferences Later
-
-See the `## Changing Preferences` section in `SKILL.md` for the canonical list of common edits (pin backend, change defaults, retrigger setup). Full schema: `preferences-schema.md`.

-## Best Practices
-
-1. **Consistency**: Use same watermark across all images in series
-2. **Legibility**: Ensure watermark readable on both light/dark areas
-3. **Size**: Keep subtle - should not distract from content
-
-## Prompt Integration
-
-When watermark is enabled, add to image generation prompt:
-
-```
-Include a subtle watermark "[content]" positioned at [position].
-The watermark should be legible but not distracting from the main content.
-```
-
-## Common Issues
-
-| Issue | Solution |
-|-------|----------|
-| Watermark invisible | Adjust position or check contrast |
-| Watermark too prominent | Change position or reduce size |
-| Watermark overlaps content | Change position |
-| Inconsistent across images | Use session ID for consistency |

-# Confirmation Questions
-
-Concrete option copy for Step 2 Smart Confirm. SKILL.md states which question to ask and when — this file supplies the verbatim options used in Claude Code. Other runtimes should adapt the wording to their native user-input tool while preserving intent.
-
-## Step 2 — Smart Confirm Entry
-
-Single-question confirmation presented right after the auto-recommended plan.
-
-```yaml
-header: Mode
-question: How to proceed with the recommended plan?
-options:
-  - label: 1. ✅ 确认，直接生成（推荐）
-    description: Trust auto-recommendation and proceed immediately
-  - label: 2. 🎛️ 自定义调整
-    description: Modify strategy/style/layout/count in one step
-  - label: 3. 📋 详细模式
-    description: Generate 3 outline variants, then choose (two confirmations)
-```
-
-## Path B — Customize (Option 2)
-
-Batch these five questions. Leaving a field blank keeps the recommended value.
-
-```yaml
-header: Style/Strategy
-question: "Strategy + style. Current: {strategy} + {style}"
-hint: |
-  Strategies: A Story-Driven (warm) | B Information-Dense (notion) | C Visual-First (screen-print)
-  Styles: cute / fresh / warm / bold / minimal / retro / pop / notion / chalkboard / study-notes / screen-print / sketch-notes
-  Presets: knowledge-card / checklist / tutorial / poster / hand-drawn-edu / ...
-```
-
-```yaml
-header: Layout
-question: "Layout. Current: {layout}"
-options: [sparse, balanced, dense, list, comparison, flow, mindmap, quadrant]
-```
-
-```yaml
-header: Palette
-question: "Palette. Current: {palette or 默认}"
-options: [默认, macaron, warm, neon]
-```
-
-```yaml
-header: Count
-question: "Image count. Current: {N}"
-hint: Range 2-10
-```
-
-```yaml
-header: Notes
-question: Optional notes (selling-point emphasis, audience adjustment, color preference)
-optional: true
-```
-
-## Path C — Detailed Mode
-
-### Step 2a: Content Understanding
-
-Batch these questions.
-
-```yaml
-header: SellingPoints
-question: Core selling points (pick all that apply)
-multiSelect: true
-```
-
-```yaml
-header: Audience
-question: Target audience
-```
-
-```yaml
-header: Tone
-question: Style preference
-options:
-  - label: Authentic sharing
-  - label: Professional review
-  - label: Aesthetic mood
-  - label: Auto
-```
-
-```yaml
-header: Context
-question: Additional context (optional)
-optional: true
-```
-
-### Step 2c: Outline & Style Selection
-
-Batch these three questions.
-
-```yaml
-header: Strategy
-question: Which outline strategy?
-options:
-  - label: A — Story-Driven
-  - label: B — Information-Dense
-  - label: C — Visual-First
-  - label: Combine (specify pages from each)
-```
-
-```yaml
-header: Style
-question: Visual style?
-options:
-  - label: Use recommended
-  - label: Select preset
-  - label: Select style directly
-  - label: Custom description
-```

-header: Elements
-question: Visual elements?
-options:
-  - label: Use defaults (Recommended)
-  - label: Adjust background
-  - label: Adjust decorations

-## Outline Variant Frontmatter
-
-Used by Path C when writing the three `outline-strategy-{a,b,c}.md` files. Each variant MUST have a different structure AND a different recommended style — include `style_reason` explaining why the style fits the strategy.
-
-```yaml

-Soft pastel macaron color palette. Use block colors as rounded card backgrounds for distinct information sections. Accent coral red sparingly for emphasis on key terms only. All colors should feel gentle and approachable — no saturated or neon tones. Do NOT render color names or role labels as visible text in the image.

-Vibrant neon color palette on dark background. Colors should glow against the dark base. High contrast, futuristic feel. Use neon sparingly — too many glowing elements become chaotic. Let dark background breathe. Do NOT render color names, hex codes, or role labels as visible text in the image.
