 # Release Skills
 
 Universal release workflow supporting any project type with multi-language changelog.
 
+## 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.

 ## Workflow
 
 ### Step 1: Detect Project Configuration
 
 1. Check for `.releaserc.yml` (optional config override)
+   - If present, inspect whether it defines release hooks
 2. Auto-detect version file by scanning (priority order):
    - `package.json` (Node.js)
    - `pyproject.toml` (Python)

    - `CHANGES*.md`
 4. Identify language of each changelog by filename suffix
-5. Display detected configuration
+5. Detect GitHub release support:
+   - Check whether `origin` points to GitHub
+   - Check whether `gh` is installed and authenticated
+   - Check existing releases with `gh release list --limit 5` when available
+6. Display detected configuration
+
+**Project Hook Contract**:
+
+If `.releaserc.yml` defines `release.hooks`, keep the release workflow generic and delegate project-specific packaging/publishing to those hooks.
+
+Supported hooks:
+
+| Hook | Purpose | Expected Responsibility |
+|------|---------|-------------------------|
+| `prepare_artifact` | Make one target releasable | Validate the target is self-contained, sync/embed local dependencies, optionally stage extra files |
+| `publish_artifact` | Publish one releasable target | Upload the prepared target (or a staged directory if the project uses one), attach version/changelog/tags |
+
+Supported placeholders:
+
+| Placeholder | Meaning |
+|-------------|---------|
+| `{project_root}` | Absolute path to repository root |
+| `{target}` | Absolute path to the module/skill being released |
+| `{artifact_dir}` | Absolute path to a temporary staging directory for this target, when the project uses one |
+| `{version}` | Version selected by the release workflow |
+| `{dry_run}` | `true` or `false` |
+| `{release_notes_file}` | Absolute path to a UTF-8 file containing release notes/changelog text |
+
+Execution rules:
+- Keep the skill generic: do not hardcode registry/package-manager/project layout details into this SKILL.
+- If `prepare_artifact` exists, run it once per target before publish-related checks that need the final releasable target state.
+- Write release notes to a temp file and pass that file path to `publish_artifact`; do not inline multiline changelog text into shell commands.
+- If hooks are absent, fall back to the default project-agnostic release workflow.
 
 **Language Detection Rules**:
 
-| Filename Pattern | Language |
-|------------------|----------|
-| `CHANGELOG.md` (no suffix) | en (default) |
-| `CHANGELOG.zh.md` / `CHANGELOG_CN.md` / `CHANGELOG.zh-CN.md` | zh |
-| `CHANGELOG.ja.md` / `CHANGELOG_JP.md` | ja |
-| `CHANGELOG.ko.md` / `CHANGELOG_KR.md` | ko |
-| `CHANGELOG.de.md` / `CHANGELOG_DE.md` | de |
-| `CHANGELOG.fr.md` / `CHANGELOG_FR.md` | fr |
-| `CHANGELOG.es.md` / `CHANGELOG_ES.md` | es |
-| `CHANGELOG.{lang}.md` | Corresponding language code |
+Changelog files follow the pattern `CHANGELOG_{LANG}.md` or `CHANGELOG.{lang}.md`, where `{lang}` / `{LANG}` is a language or region code.
+
+| Pattern | Example | Language |
+|---------|---------|----------|
+| No suffix | `CHANGELOG.md` | en (default) |
+| `_{LANG}` (uppercase) | `CHANGELOG_CN.md`, `CHANGELOG_JP.md` | Corresponding language |
+| `.{lang}` (lowercase) | `CHANGELOG.zh.md`, `CHANGELOG.ja.md` | Corresponding language |
+| `.{lang-region}` | `CHANGELOG.zh-CN.md` | Corresponding region variant |
+
+Common language codes: `zh` (Chinese), `ja` (Japanese), `ko` (Korean), `de` (German), `fr` (French), `es` (Spanish).

+## Backfill Existing GitHub Releases
+
+Use this mode when the user asks to backfill historical releases or passes `--backfill-releases`.

+1. Do not bump versions, edit changelogs, or create release commits.
+2. List existing tags in version order and detect missing releases:
+   ```bash
+   git tag --sort=v:refname
+   gh release view <tag>
+   ```
+3. For each tag without a GitHub Release:
+   - Normalize the changelog lookup by stripping the configured tag prefix, e.g. `v1.2.3` -> `1.2.3`
+   - Extract the matching section from `CHANGELOG.md`; fall back to the first matching changelog file
+   - Skip or ask before publishing if no matching changelog section exists
+   - Create the release with:
+     ```bash
+     gh release create <tag> --title "<tag>" --notes-file <release-notes-file> --verify-tag
+     ```
+4. Detect lightweight tags with `git cat-file -t <tag>` (`commit` means lightweight, `tag` means annotated).
+5. Do not rewrite public lightweight tags by default. Converting an existing remote tag to an annotated tag requires explicit user confirmation because it rewrites a published reference.

-## Project Overview
-
-Claude Code marketplace plugin providing AI-powered content generation skills. Skills use Gemini Web API (reverse-engineered) for text/image generation and Chrome CDP for browser automation.
+Claude Code marketplace plugin providing AI-powered content generation skills. Version: **2.0.0**.
 
 ## Architecture
 
-Skills are organized into three plugin categories in `marketplace.json`:
+Skills are exposed through the single `baoyu-skills` plugin in `.claude-plugin/marketplace.json` (which defines plugin metadata, version, and skill paths). The repo docs still group them into three logical areas:

-|----------|-------------|
-| `content-skills` | Skills that generate or publish content (images, slides, comics, posts) |
-| `ai-generation-skills` | Backend skills providing AI generation capabilities |
-| `utility-skills` | Helper tools for content processing (conversion, compression) |
+Each skill contains `SKILL.md` (YAML front matter + docs), optional `scripts/`, `references/`, `prompts/`.
 
-Each skill contains:
-- `SKILL.md` - YAML front matter (name, description) + documentation
-- `scripts/` - TypeScript implementations
-- `prompts/system.md` - AI generation guidelines (optional)
+Top-level `scripts/` contains repo maintenance utilities (sync, hooks, publish).
 
 ## Running Skills
 
-All scripts run via Bun (no build step):
-
+TypeScript via Bun (no build step). Detect runtime once per session:
 ```bash
-npx -y bun skills/<skill>/scripts/main.ts [options]
+if command -v bun &>/dev/null; then BUN_X="bun"
+elif command -v npx &>/dev/null; then BUN_X="npx -y bun"
+else echo "Error: install bun: brew install oven-sh/bun/bun or npm install -g bun"; exit 1; fi
 ```
 
-Examples:
-```bash
-# Text generation
-npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts "Hello"
-
-# Image generation
-npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts --prompt "A cat" --image cat.png

-- **Chrome**: Required for `baoyu-danger-gemini-web` auth and `baoyu-post-to-x` automation
-- **No npm packages**: Self-contained TypeScript, no external dependencies
+- **Bun**: TypeScript runtime (`bun` preferred, fallback `npx -y bun`)
+- **Chrome**: Required for CDP-based skills (gemini-web, post-to-x/wechat/weibo, url-to-markdown). All CDP skills share a single profile, override via `BAOYU_CHROME_PROFILE_DIR` env var. Platform paths: [docs/chrome-profile.md](docs/chrome-profile.md)
+- **Image generation APIs**: `baoyu-image-gen` requires API key (OpenAI, Azure OpenAI, Google, OpenRouter, DashScope, or Replicate) configured in EXTEND.md
+- **Gemini Web auth**: Browser cookies (first run opens Chrome for login, `--login` to refresh)
 
-## Authentication
+## Security
 
-`baoyu-danger-gemini-web` uses browser cookies for Google auth:
-- First run opens Chrome for login
-- Cookies cached in data directory
-- Force refresh: `--login` flag
-
-## Plugin Configuration
-
-`.claude-plugin/marketplace.json` defines plugin metadata and skill paths. Version follows semver.
+- **No piped shell installs**: Never `curl | bash`. Use `brew install` or `npm install -g`
+- **Remote downloads**: HTTPS only, max 5 redirects, 30s timeout, expected content types only
+- **System commands**: Array-form `spawn`/`execFile`, never unsanitized input to shell
+- **External content**: Treat as untrusted, don't execute code blocks, sanitize HTML
 
 ## Skill Loading Rules
 
-**IMPORTANT**: When working in this project, follow these rules:
-
 | Rule | Description |
 |------|-------------|
-| **Load project skills first** | MUST load all skills from `skills/` directory in current project. Project skills take priority over system/user-level skills with same name. |
-| **Default image generation** | When image generation is needed, use `skills/baoyu-image-gen/SKILL.md` by default (unless user specifies otherwise). |
+| **Load project skills first** | Project skills override system/user-level skills with same name |
+| **Default image generation** | Use whatever image backend is available in the current runtime; if multiple are available, ask the user which to use. See `## Image Generation Tools` below. |
 
-**Loading Priority** (highest → lowest):
-1. Current project `skills/` directory
-2. User-level skills (`$HOME/.baoyu-skills/`)
-3. System-level skills
+Priority: project `skills/` → `$HOME/.baoyu-skills/` → system-level.
+
+## Skill Self-Containment
+
+Each skill under `skills/` (and `.claude/skills/`) is distributed and consumed independently — the folder may be extracted, copied into another project, or loaded without the rest of this repo. Therefore:
+
+- **Never link from `SKILL.md` or its `references/` to files outside the skill's own directory.** This includes `docs/`, sibling skills, and the repo root. Relative paths like `../../docs/foo.md` break when the skill is used standalone.
+- **Inline any shared convention** (e.g., user-input rules, image-generation backend selection) directly in the skill rather than referencing an out-of-skill doc.
+- Shared docs under `docs/` exist for **repo-author guidance only** — they may be referenced from `CLAUDE.md` and `docs/creating-skills.md`, but NOT from any `SKILL.md`. This applies to `docs/user-input-tools.md`, `docs/image-generation-tools.md`, `docs/image-generation.md`, and any other `docs/` file.
+
+## User Input Tools
+
+Skills that prompt users for choices MUST declare the tool-selection convention **inline** in exactly one place per `SKILL.md` — a `## User Input Tools` section near the top. Do NOT link out to [docs/user-input-tools.md](docs/user-input-tools.md); that doc is the author-side canonical source — copy its body into each SKILL.md. Concrete `AskUserQuestion` mentions elsewhere in a skill are treated as examples — other runtimes substitute their local equivalent under the rule.
+
+## Image Generation Tools
+
+Skills that render images MUST declare the backend-selection convention **inline** in exactly one place per `SKILL.md` — a `## Image Generation Tools` section near the top (after `## User Input Tools`). Do NOT link out to [docs/image-generation-tools.md](docs/image-generation-tools.md); that doc is the author-side canonical source — copy its body into each SKILL.md. Concrete tool names (`imagegen`, `GenerateImage`, `image_generate`, `baoyu-image-gen`) elsewhere in a skill are treated as examples — other runtimes substitute their local equivalent under the rule. The rule is stateless: use whatever backend is available; if multiple, ask the user once; if none, ask how to proceed. Every rendered image's full prompt must be written to a standalone `prompts/NN-*.md` file before any backend is invoked. Backend skills (`baoyu-image-gen`, `baoyu-danger-gemini-web`) are exempt — they render directly rather than selecting a backend.
+
+### `codex-imagegen` Backend
+
+A backend for non-Codex runtimes (e.g., Claude Code) that generates images by spawning `codex exec --json --sandbox danger-full-access` and delegating to Codex CLI's built-in `image_gen` tool. Uses the user's Codex subscription — no `OPENAI_API_KEY` required. Lives under [packages/baoyu-codex-imagegen](packages/baoyu-codex-imagegen) so it follows the same workspace layout as other shared packages.
+
+Invoke via (TS entrypoint with `#!/usr/bin/env bun` shebang):
+
+```bash
+bun packages/baoyu-codex-imagegen/src/main.ts \
+  --image <output.png> \
+  --prompt-file prompts/01-cover.md \
+  --aspect 16:9 \
+  --cache-dir ~/.cache/baoyu-codex-imagegen
+```
+
+Without bun installed: `npx -y bun packages/baoyu-codex-imagegen/src/main.ts …`.
+
+Stdout emits a single JSON line: `{"status":"ok","path":...,"bytes":N,...}`. On failure, `{"status":"error","error_kind":...}`. Skills route here by setting `preferred_image_backend: codex-imagegen` in EXTEND.md, or by running `baoyu-image-gen --provider codex-cli` (which spawns the same wrapper internally). Full reference: [docs/codex-imagegen-backend.md](docs/codex-imagegen-backend.md).
 
 ## Release Process
 
-**IMPORTANT**: When user requests release/发布/push, ALWAYS use `/release-skills` workflow.
-
-**Never skip**:
-1. `CHANGELOG.md` + `CHANGELOG.zh.md` - Both must be updated
+Use `/release-skills` workflow. Never skip:

-## Adding New Skills
-
-**IMPORTANT**: All skills MUST use `baoyu-` prefix to avoid conflicts when users import this plugin.
-
-**REQUIRED READING**: Before creating a new skill, read the official [Skill authoring best practices](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices).
-
-### Key Requirements from Official Best Practices
-
-| Requirement | Details |
-|-------------|---------|
-| **Concise is key** | Claude is smart—only add context it doesn't have. Challenge each token. |
-| **name field** | Max 64 chars, lowercase letters/numbers/hyphens only, no "anthropic"/"claude" |
-| **description field** | Max 1024 chars, non-empty, MUST be third person, include what + when to use |
-| **SKILL.md body** | Keep under 500 lines; use separate files for additional content |
-| **Naming convention** | Gerund form preferred (e.g., `processing-pdfs`), but `baoyu-` prefix required here |
-| **References** | Keep one level deep from SKILL.md; avoid nested references |
-| **No time-sensitive info** | Avoid dates/versions that become outdated |
-
-### Steps
-
-1. Create `skills/baoyu-<name>/SKILL.md` with YAML front matter
-   - Directory name: `baoyu-<name>`
-   - SKILL.md `name` field: `baoyu-<name>`
-2. Add TypeScript in `skills/baoyu-<name>/scripts/`
-3. Add prompt templates in `skills/baoyu-<name>/prompts/` if needed
-4. **Choose the appropriate category** and register in `marketplace.json`:
-   - `content-skills`: For content generation/publishing (images, slides, posts)
-   - `ai-generation-skills`: For AI backend capabilities
-   - `utility-skills`: For helper tools (conversion, compression)
-   - If none fit, create a new category with descriptive name
-5. **Add Script Directory section** to SKILL.md (see template below)
-
-### Choosing a Category
-
-| If your skill... | Use category |
-|------------------|--------------|
-| Generates visual content (images, slides, comics) | `content-skills` |
-| Publishes to platforms (X, WeChat, etc.) | `content-skills` |
-| Provides AI generation backend | `ai-generation-skills` |
-| Converts or processes content | `utility-skills` |
-| Compresses or optimizes files | `utility-skills` |
-
-**Creating a new category**: If the skill doesn't fit existing categories, add a new plugin object to `marketplace.json` with:
-- `name`: Descriptive kebab-case name (e.g., `analytics-skills`)
-- `description`: Brief description of the category
-- `skills`: Array with the skill path
-
-### Writing Effective Descriptions
-
-**MUST write in third person** (not "I can help you" or "You can use this"):
-
-```yaml
-# Good
-description: Generates Xiaohongshu infographic series from content. Use when user asks for "小红书图片", "XHS images", or "RedNote infographics".
-
-# Bad
-description: I can help you create Xiaohongshu images
-description: You can use this to generate XHS content
-```
-
-Include both **what** the skill does and **when** to use it (triggers/keywords).
-
-### Script Directory Template
-
-Every SKILL.md with scripts MUST include this section after Usage:
-
-```markdown
-## Script Directory
-
-**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
-
-**Agent Execution Instructions**:
-1. Determine this SKILL.md file's directory path as `SKILL_DIR`
-2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
-3. Replace all `${SKILL_DIR}` in this document with the actual path
-
-**Script Reference**:
-| Script | Purpose |
-|--------|---------|
-| `scripts/main.ts` | Main entry point |
-| `scripts/other.ts` | Other functionality |
-```
-
-When referencing scripts in workflow sections, use `${SKILL_DIR}/scripts/<name>.ts` so agents can resolve the correct path.
-
-### Progressive Disclosure
-
-For skills with extensive content, use separate reference files:
-
-```
-skills/baoyu-example/
-├── SKILL.md              # Main instructions (<500 lines)
-├── references/
-│   ├── styles.md         # Style definitions (loaded as needed)
-│   └── examples.md       # Usage examples (loaded as needed)
-└── scripts/
-    └── main.ts           # Executable script
-```
-
-In SKILL.md, link to reference files (one level deep only):
-```markdown
-**Available styles**: See [references/styles.md](references/styles.md)
-**Examples**: See [references/examples.md](references/examples.md)
-```
-
 ## Code Style
 
-- TypeScript throughout, no comments
-- Async/await patterns
-- Short variable names
-- Type-safe interfaces
+TypeScript, no comments, async/await, short variable names, type-safe interfaces.
 
-## Image Generation Guidelines
+## Adding New Skills
 
-Skills that require image generation MUST delegate to available image generation skills rather than implementing their own.
+All skills MUST use `baoyu-` prefix. Details: [docs/creating-skills.md](docs/creating-skills.md)
 
-### Image Generation Skill Selection
+## Reference Docs
 
-**Default**: Use `skills/baoyu-image-gen/SKILL.md` (unless user specifies otherwise).
-
-1. Read `skills/baoyu-image-gen/SKILL.md` for parameters and capabilities
-2. If user explicitly requests a different skill, check `skills/` directory for alternatives
-3. Only ask user to choose when they haven't specified and multiple viable options exist
-
-### Generation Flow Template
-
-Use this template when implementing image generation in skills:
-
-```markdown
-### Step N: Generate Images
-
-**Skill Selection**:
-1. Check available image generation skills (e.g., `baoyu-danger-gemini-web`)
-2. Read selected skill's SKILL.md for parameter reference
-3. If multiple skills available, ask user to choose
-
-**Generation Flow**:
-1. Call selected image generation skill with:
-   - Prompt file path (or inline prompt)
-   - Output image path
-   - Any skill-specific parameters (refer to skill's SKILL.md)
-2. Generate images sequentially (one at a time)
-3. After each image, output progress: "Generated X/N"
-4. On failure, auto-retry once before reporting error
-```
-
-### Output Path Convention
-
-Each session creates an independent directory. Even the same source file generates a new directory per session.
-
-**Output Directory**:
-```
-<skill-suffix>/<topic-slug>/
-```
-- `<skill-suffix>`: Skill name suffix (e.g., `xhs-images`, `cover-image`, `slide-deck`, `comic`)
-- `<topic-slug>`: Generated from content topic (2-4 words, kebab-case)
-- Example: `xhs-images/ai-future-trends/`
-
-**Slug Generation**:
-1. Extract main topic from content (2-4 words, kebab-case)
-2. Example: "Introduction to Machine Learning" → `intro-machine-learning`
-
-**Conflict Resolution**:
-If `<skill-suffix>/<topic-slug>/` already exists:
-- Append timestamp: `<topic-slug>-YYYYMMDD-HHMMSS`
-- Example: `ai-future` exists → `ai-future-20260118-143052`
-
-**Source Files**:
-- Copy all sources to `<skill-suffix>/<topic-slug>/` with naming: `source-{slug}.{ext}`
-- Multiple sources supported: text, images, files from conversation
-- Examples:
-  - `source-article.md` (main text content)
-  - `source-reference.png` (image from conversation)
-  - `source-data.csv` (additional file)
-- Original source files remain unchanged
-
-### Image Naming Convention
-
-Image filenames MUST include meaningful slugs for readability:
-
-**Format**: `NN-{type}-[slug].png`
-- `NN`: Two-digit sequence number (01, 02, ...)
-- `{type}`: Image type (cover, content, page, slide, illustration, etc.)
-- `[slug]`: Descriptive kebab-case slug derived from content
-
-**Examples**:
-```
-01-cover-ai-future.png
-02-content-key-benefits.png
-03-page-enigma-machine.png
-04-slide-architecture-overview.png
-```
-
-**Slug Rules**:
-- Derived from image purpose or content (kebab-case)
-- Must be unique within the output directory
-- 2-5 words, concise but descriptive
-- When content changes significantly, update slug accordingly
-
-### Best Practices
-
-- Always read the image generation skill's SKILL.md before calling
-- Pass parameters exactly as documented in the skill
-- Handle failures gracefully with retry logic
-- Provide clear progress feedback to user
-
-## Style Maintenance (baoyu-comic)
-
-When adding, updating, or deleting styles for `baoyu-comic`, follow this workflow:
-
-### Adding a New Style
-
-1. **Create style definition**: `skills/baoyu-comic/references/styles/<style-name>.md`
-2. **Update SKILL.md**:
-   - Add style to `--style` options table
-   - Add auto-selection entry if applicable
-3. **Generate showcase image**:
-   ```bash
-   npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts \
-     --prompt "A single comic book page in <style-name> style showing [appropriate scene]. Features: [style characteristics from style definition]. 3:4 portrait aspect ratio comic page." \
-     --image screenshots/comic-styles/<style-name>.png
-   ```
-4. **Compress to WebP**:
-   ```bash
-   npx -y bun skills/baoyu-compress-image/scripts/main.ts screenshots/comic-styles/<style-name>.png
-   ```
-5. **Update both READMEs** (`README.md` and `README.zh.md`):
-   - Add style to `--style` options
-   - Add row to style description table
-   - Add image to style preview grid
-
-### Updating an Existing Style
-
-1. **Update style definition**: `skills/baoyu-comic/references/styles/<style-name>.md`
-2. **Regenerate showcase image** (if visual characteristics changed):
-   - Follow steps 3-4 from "Adding a New Style"
-3. **Update READMEs** if description changed
-
-### Deleting a Style
-
-1. **Delete style definition**: `skills/baoyu-comic/references/styles/<style-name>.md`
-2. **Delete showcase image**: `screenshots/comic-styles/<style-name>.webp`
-3. **Update SKILL.md**:
-   - Remove from `--style` options
-   - Remove auto-selection entry
-4. **Update both READMEs**:
-   - Remove from `--style` options
-   - Remove from style description table
-   - Remove from style preview grid
-
-### Style Preview Grid Format
-
-READMEs use 3-column tables for style previews:
-
-```markdown
-| | | |
-|:---:|:---:|:---:|
-| ![style1](./screenshots/comic-styles/style1.webp) | ![style2](./screenshots/comic-styles/style2.webp) | ![style3](./screenshots/comic-styles/style3.webp) |
-| style1 | style2 | style3 |
-```
-
-## Extension Support
-
-Every SKILL.md MUST include two parts for extension support:
-
-### 1. Load Preferences Section (in Step 1 or as "Preferences" section)
-
-For skills with workflows, add as Step 1.1. For utility skills, add as "Preferences (EXTEND.md)" section before Usage:
-
-```markdown
-**1.1 Load Preferences (EXTEND.md)**
-
-Use Bash to check EXTEND.md existence (priority order):
-
-\`\`\`bash
-# Check project-level first
-test -f .baoyu-skills/<skill-name>/EXTEND.md && echo "project"
-
-# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
-test -f "$HOME/.baoyu-skills/<skill-name>/EXTEND.md" && echo "user"
-\`\`\`

-└───────────┴───────────────────────────────────────────────────────────────────────────┘
-
-**EXTEND.md Supports**: [List supported configuration options for this skill]
-
-Schema: `references/config/preferences-schema.md`
-```
-
-### 2. Extension Support Section (at the end)
-
-Simplified section that references the preferences section:
-
-```markdown
-## Extension Support
-
-Custom configurations via EXTEND.md. See **Step 1.1** for paths and supported options.
-```
-
-Or for utility skills without workflow steps:
-
-```markdown
-## Extension Support
-
-Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.
-```
-
-**Notes**:
-- Replace `<skill-name>` with actual skill name (e.g., `baoyu-cover-image`)
-- Use `$HOME` instead of `~` for cross-platform compatibility (macOS/Linux/WSL)
-- Use `test -f` Bash command for explicit file existence check
-- ASCII tables for clear visual formatting

+#### baoyu-diagram
+
+Generate publication-ready SVG diagrams from source material — flowcharts, sequence/protocol diagrams, structural/architecture diagrams, and illustrative intuition diagrams. Analyzes input material to recommend diagram type(s) and splitting strategy, confirms the plan once, then generates all diagrams. Claude writes real SVG code directly following a cohesive design system. Output is self-contained `.svg` files with embedded styles and auto dark-mode.
+
+```bash
+# Topic string — skill analyzes and proposes a plan
+/baoyu-diagram "how JWT authentication works"
+/baoyu-diagram "Kubernetes architecture" --type structural
+/baoyu-diagram "OAuth 2.0 flow"          --type sequence

+# Language and output path
+/baoyu-diagram "微服务架构" --lang zh
+/baoyu-diagram "build pipeline" --out docs/build-pipeline.svg
+```
+
+**Options**:
+| Option | Description |
+|--------|-------------|
+| `--type <name>` | `flowchart`, `sequence`, `structural`, `illustrative`, `class`, `auto` (default). Skips type recommendation. |
+| `--lang <code>` | Output language (en, zh, ja, ...) |
+| `--out <path>` | Output file path. Generates exactly one diagram focused on the most important aspect. |
+
+**Diagram types**:
+
+| Type | Reader need | Verbs that trigger it |
+|------|-------------|------------------------|
+| `flowchart` | Walk me through the steps in order | walk through, steps, process, lifecycle, workflow, state machine |
+| `sequence` | Who talks to whom, in what order | protocol, handshake, auth flow, OAuth, TCP, request/response |
+| `structural` | Show me what's inside what, how it's organised | architecture, components, topology, layout, what's inside |
+| `illustrative` | Give me the intuition — draw the mechanism | how does X work, explain X, intuition for, why does X do Y |
+| `class` | What are the types and how are they related | class diagram, UML, inheritance, interface, schema |
+
+Not an image-generation skill — no LLM image model is called. Claude writes the SVG by hand with hand-computed layout math, so every diagram honors the design system. Embedded `<style>` block with `@media (prefers-color-scheme: dark)` means the same file renders correctly in both light and dark mode anywhere it's embedded.

-Prerequisites: Google Chrome installed. First run requires QR code login (session preserved).
+**Publishing Methods**:
+
+| Method | Speed | Requirements |
+|--------|-------|--------------|
+| API (Recommended) | Fast | API credentials (local IP allowlisted in WeChat) |
+| Browser | Slow | Chrome, login session |
+| Remote API | Fast | API credentials + SSH-reachable server whose IP is on WeChat's allowlist |
+
+**API Configuration** (for faster publishing):
+
+```bash
+# Add to .baoyu-skills/.env (project-level) or ~/.baoyu-skills/.env (user-level)
+WECHAT_APP_ID=your_app_id
+WECHAT_APP_SECRET=your_app_secret
+```
+
+To obtain credentials:
+1. Visit https://developers.weixin.qq.com/platform/
+2. Go to: 我的业务 → 公众号 → 开发密钥
+3. Create development key and copy AppID/AppSecret
+4. Add your machine's IP to the whitelist
+
+**Browser Method** (no API setup needed): Requires Google Chrome. First run opens browser for QR code login (session preserved).
+
+**Remote API Method** (for when WeChat's IP allowlist excludes your local machine): tunnels WeChat API calls through an SSH SOCKS5 dynamic port forward to a server whose IP is on the allowlist. No files are written to the remote host and `AppSecret` never leaves the local process. Add to your EXTEND.md:
+
+```yaml
+# Optional: only set when WeChat's IP allowlist excludes your local machine
+remote_publish_host: server.example.com
+remote_publish_user: deploy
+remote_publish_identity_file: ~/.ssh/id_ed25519
+```
+
+Then publish with `--remote` (or set `default_publish_method: remote-api`). Authentication is SSH key only; only the typed `remote_publish_*` keys are honored.
+
+**Multi-Account Support**: Manage multiple WeChat Official Accounts via `EXTEND.md`:
+
+```bash
+mkdir -p .baoyu-skills/baoyu-post-to-wechat
+```
+
+Create `.baoyu-skills/baoyu-post-to-wechat/EXTEND.md`:

+- DashScope: `qwen-image-2.0-pro` is the recommended default for custom `--size`, `21:9`, and strong Chinese/English text rendering.
+- Z.AI: `glm-image` is recommended for posters, diagrams, and text-heavy Chinese/English images. Reference images are not supported.
+- MiniMax: `image-01` supports documented custom `width` / `height`; `image-01-live` is lower latency and works best with `--ar`.
+- MiniMax reference images are sent as `subject_reference`; the current API is specialized toward character / portrait consistency.
+- Jimeng does not support reference images.
+- Seedream reference images are supported by Seedream 5.0 / 4.5 / 4.0, not Seedream 3.0.
+- Replicate defaults to `google/nano-banana-2`. `baoyu-image-gen` only enables Replicate advanced options for `google/nano-banana*`, `bytedance/seedream-4.5`, `bytedance/seedream-5-lite`, `wan-video/wan-2.7-image`, and `wan-video/wan-2.7-image-pro`.
+- Replicate currently saves exactly one output image per request. `--n > 1` is blocked locally instead of silently dropping extra results.
+- Replicate model behavior is family-specific: nano-banana uses `--quality` / `--ar`, Seedream uses validated `--size` / `--ar`, and Wan uses validated `--size` (with `--ar` converted locally to a concrete size).
 
 **Provider Auto-Selection**:
-1. If `--provider` specified → use it
-2. If only one API key available → use that provider
-3. If both available → default to Google

+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.
+
+```bash
+# Extract by app name (default output: ~/Downloads/Codex-electron-extract/)
+/baoyu-electron-extract Codex
+
+# Extract by absolute path (.app bundle, install dir, or .asar file)
+/baoyu-electron-extract "/Applications/Visual Studio Code.app"
+/baoyu-electron-extract --asar /Applications/Codex.app/Contents/Resources/app.asar Codex
+
+# Custom output directory
+/baoyu-electron-extract Codex --output ~/work/codex-source
+
+# Preview discovery without writing anything
+/baoyu-electron-extract Codex --dry-run
+
+# Overwrite an existing output directory
+/baoyu-electron-extract Codex --force
+```
+
+**Options**:
+| Option | Description | Default |
+|--------|-------------|---------|
+| `<app>` | App name or absolute path (required unless `--asar`) | — |
+| `--output`, `-o` | Output directory | `~/Downloads/<AppName>-electron-extract` |
+| `--asar` | Override the resolved `.asar` path | auto-discovered |
+| `--force`, `-f` | Allow writing into a non-empty existing output dir | false |
+| `--skip-format` | Skip Prettier formatting | false |
+| `--skip-restore` | Skip source-map restoration | false |
+| `--no-unpacked` | Don't copy `app.asar.unpacked/` alongside | false |
+| `--dry-run` | Print resolved paths and exit without writing | false |
+| `--json` | Emit one JSON-line summary on stdout | false |
+
+**Output layout**: `extract-report.json` (counts, warnings, paths), `extracted/` (raw asar, formatted in place when no map), `extracted.unpacked/` (native modules if present), and `restored/` (rebuilt source tree from `.js.map` files).

+从源素材生成可直接发布的 SVG 图表 —— 包括流程图、时序/协议图、架构/结构图、示意图（直觉图解）。分析输入素材，推荐图表类型和拆分策略，一次确认后批量生成。Claude 直接输出符合统一设计规范的真实 SVG 代码，产物是自包含的 `.svg` 文件，内嵌样式并自动支持深色模式。
+
+```bash
+# 主题描述 —— 技能分析并提出方案
+/baoyu-diagram "JWT 认证流程是怎么工作的"
+/baoyu-diagram "Kubernetes 架构" --type structural
+/baoyu-diagram "OAuth 2.0 流程"  --type sequence
+
+# 文件路径 —— 技能读取、分析并提出方案
+/baoyu-diagram path/to/article.md
+
+# 语言和输出路径
+/baoyu-diagram "微服务架构" --lang zh
+/baoyu-diagram "build pipeline" --out docs/build-pipeline.svg
+```
+
+**参数**：
+| 参数 | 说明 |
+|------|------|
+| `--type <name>` | `flowchart`、`sequence`、`structural`、`illustrative`、`class`、`auto`（默认）。跳过类型推荐直接生成。 |
+| `--lang <code>` | 输出语言（en、zh、ja 等） |
+| `--out <path>` | 输出文件路径。生成聚焦于最重要内容的单张图表。 |
+
+**五种图表类型**：
+
+| 类型 | 适用场景 | 触发动词 |
+|------|----------|----------|
+| `flowchart` | 按顺序走一遍流程 | 流程、步骤、工作流、生命周期、状态机 |
+| `sequence` | 谁和谁通信、按什么顺序 | 协议、握手、认证流程、OAuth、TCP、请求/响应 |
+| `structural` | 展示什么包含什么、如何组织 | 架构、组件、拓扑、布局、什么在什么里面 |
+| `illustrative` | 建立直觉 —— 画出机制本身 | 怎么工作、原理、为什么、直观解释 |
+| `class` | 类型是什么、它们如何关联 | 类图、UML、继承、接口、数据模型 |
+
+本技能不调用任何图像生成模型 —— Claude 通过手算坐标直接写 SVG 代码，确保每个图表都遵守设计规范。内嵌的 `<style>` 块包含 `@media (prefers-color-scheme: dark)`，同一个文件在浅色和深色模式下均正确渲染，可嵌入到任意支持 SVG 的宿主环境中。

+- DashScope：`qwen-image-2.0-pro` 是自定义 `--size`、`21:9` 和中英文排版的推荐默认模型。
+- Z.AI：`glm-image` 适合海报、图表和中英文排版密集的图片生成，暂不支持参考图。
+- MiniMax：`image-01` 支持官方文档里的自定义 `width` / `height`；`image-01-live` 更偏低延迟，适合配合 `--ar` 使用。
+- MiniMax 参考图会走 `subject_reference`，当前能力更偏角色 / 人像一致性。
+- 即梦不支持参考图。
+- 豆包参考图能力仅适用于 Seedream 5.0 / 4.5 / 4.0，不适用于 Seedream 3.0。
+- Replicate 默认模型改为 `google/nano-banana-2`。`baoyu-image-gen` 目前只对 `google/nano-banana*`、`bytedance/seedream-4.5`、`bytedance/seedream-5-lite`、`wan-video/wan-2.7-image` 和 `wan-video/wan-2.7-image-pro` 开启本地能力识别与校验。
+- Replicate 当前只保存单张输出图，`--n > 1` 会在本地直接报错，避免多图结果被静默丢弃。
+- Replicate 的参数能力按模型家族区分：nano-banana 走 `--quality` / `--ar`，Seedream 走校验后的 `--size` / `--ar`，Wan 走校验后的 `--size`（`--ar` 会先在本地换算成具体尺寸）。

+# Chrome Profile
+
+All CDP skills share a single profile directory. Do NOT create per-skill profiles.

+
+| Platform | Default Path |
+|----------|-------------|
+| macOS | `~/Library/Application Support/baoyu-skills/chrome-profile` |
+| Linux | `$XDG_DATA_HOME/baoyu-skills/chrome-profile` (fallback `~/.local/share/`) |
+| Windows | `%APPDATA%/baoyu-skills/chrome-profile` |

+# `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.
+
+### Enabling within image skills
+
+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.

+# Creating New Skills
+
+**REQUIRED READING**: [Skill authoring best practices](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices)
+
+## Key Requirements
+
+| Requirement | Details |
+|-------------|---------|
+| **Prefix** | All skills MUST use `baoyu-` prefix |
+| **name field** | Max 64 chars, lowercase letters/numbers/hyphens only, no "anthropic"/"claude" |
+| **description** | Max 1024 chars, third person, include what + when to use |
+| **SKILL.md body** | Keep under 500 lines; use `references/` for additional content |
+| **References** | One level deep from SKILL.md; avoid nested references |
+
+## SKILL.md Frontmatter Template
+
+```yaml
+---
+name: baoyu-<name>
+description: <Third-person description. What it does + when to use it.>
+version: <semver matching marketplace.json>
+metadata:
+  openclaw:
+    homepage: https://github.com/JimLiu/baoyu-skills#baoyu-<name>
+    requires:          # include only if skill has scripts
+      anyBins:
+        - bun
+        - npx
+---
+```
+
+## Steps
+
+1. Create `skills/baoyu-<name>/SKILL.md` with YAML front matter
+2. Add TypeScript in `skills/baoyu-<name>/scripts/` (if applicable)
+3. Add prompt templates in `skills/baoyu-<name>/prompts/` if needed
+4. Register the skill in `.claude-plugin/marketplace.json` under the `baoyu-skills` plugin entry
+5. Add Script Directory section to SKILL.md if skill has scripts
+6. Add openclaw metadata to frontmatter
+
+## Skill Grouping
+
+All skills are registered under the single `baoyu-skills` plugin. Use these logical groups when deciding where the skill should appear in the docs:
+
+| If your skill... | Use group |
+|------------------|-----------|
+| Generates visual content (images, slides, comics) | Content Skills |
+| Publishes to platforms (X, WeChat, Weibo) | Content Skills |
+| Provides AI generation backend | AI Generation Skills |
+| Converts or processes content | Utility Skills |
+
+If you add a new logical group, update the docs that present grouped skills, but keep the skill registered under the single `baoyu-skills` plugin entry.
+
+## Writing Descriptions
+
+**MUST write in third person**:
+
+```yaml
+# Good
+description: Generates Xiaohongshu infographic series from content. Use when user asks for "小红书图片", "XHS images".
+
+# Bad
+description: I can help you create Xiaohongshu images
+```
+
+## Script Directory Template
+
+Every SKILL.md with scripts MUST include:
+
+```markdown
+## Script Directory
+
+**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
+
+**Agent Execution Instructions**:
+1. Determine this SKILL.md file's directory path as `{baseDir}`
+2. Script path = `{baseDir}/scripts/<script-name>.ts`
+3. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun
+4. Replace all `{baseDir}` and `${BUN_X}` in this document with actual values
+
+**Script Reference**:
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | Main entry point |

+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.

+
+Every SKILL.md that renders images — whether by calling an image-generation API directly or by delegating to another skill — MUST include exactly one `## Image Generation Tools` section near the top (after `## User Input Tools`, before the main workflow). The rule must be **inlined** — do NOT link to `docs/image-generation-tools.md` (skills are self-contained; see [CLAUDE.md → Skill Self-Containment](../CLAUDE.md)).

+# Image Generation Tools
+
+Skills in this repo are loaded by multiple agent runtimes (Claude Code, Codex, Cursor, Hermes, other agents, bare CLI). Each runtime exposes a different image-generation capability — some have a runtime-native tool (Codex `imagegen`, Cursor `GenerateImage`, Hermes `image_generate`), others rely on an installed skill (`baoyu-image-gen`, or user-defined). This document defines the canonical **backend-selection rule** every skill that renders images follows so skills stay portable.
+
+## The Rule
+
+When a 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 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.
+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.
+
+## The Preference Field
+
+Each image-consuming skill's `EXTEND.md` carries a single `preferred_image_backend` field:
+
+| Value | Meaning |
+|---|---|
+| `auto` (default) | Apply the auto-select rule — runtime-native preferred, fall back to only installed backend, ask if multiple non-native. |
+| `ask` | Always confirm the backend on every run, even when a runtime-native tool exists. |
+| `<backend-id>` (e.g., `codex-imagegen`, `baoyu-image-gen`, `GenerateImage`, `image_generate`) | Pin this backend when available; fall back to `auto` if it isn't. |
+
+The field is **absent-equals-auto**: older `EXTEND.md` files without this field behave exactly as if `preferred_image_backend: auto` were set. No schema version bump is needed to introduce it.
+
+## Prompt File Requirement (hard)
+
+Regardless of which backend is chosen, every skill that renders images MUST 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 allows switching backends without regenerating prompts.
+
+## How Skills Declare This
+
+Each `SKILL.md` that renders images includes **exactly one** `## Image Generation Tools` section (near the top, after `## User Input Tools` and before the main workflow) that **inlines** this rule. Skills are self-contained and cannot link to `docs/` — each skill folder must ship the rule inside its own `SKILL.md`. See [CLAUDE.md → Skill Self-Containment](../CLAUDE.md).
+
+Each skill's `references/config/preferences-schema.md` (and its `EXTEND.md` template in `first-time-setup.md`) lists `preferred_image_backend` alongside other preference fields. First-time setup does NOT ask the user about the backend — `auto` is set silently. Users who want to pin a specific backend edit `EXTEND.md` later, and each skill's `## Changing Preferences` section documents the common one-line edits.
+
+Concrete tool names (`imagegen`, `GenerateImage`, `image_generate`, `baoyu-image-gen`) in this document and in SKILL.md are **examples** — agents in other runtimes apply the rule above and substitute the local equivalent. Skill-specific parameters for these backends are illustrative; runtimes without those knobs can omit them.
+
+## Backend Skills Are Exempt
+
+Skills that **are themselves** image-generation backends — currently `baoyu-image-gen`, `baoyu-image-gen` (deprecated), and `baoyu-danger-gemini-web` — do NOT include a `## Image Generation Tools` section. They render directly via their own provider integrations and have no need to "select a backend." The rule applies only to consumer skills that delegate rendering to whatever backend the runtime exposes.

+# Image Generation Guidelines
+
+Skills that require image generation MUST delegate to available image generation tools (runtime-native tools or installed skills).
+
+**Backend selection convention**: see [image-generation-tools.md](image-generation-tools.md) for the runtime-neutral rule. Short version: use whatever backend is available; if multiple, ask the user once; if none, ask how to proceed. This document covers output conventions (naming, paths) that apply regardless of which backend is selected.
+
+## Skill Selection
+
+1. Follow the rule in [image-generation-tools.md](image-generation-tools.md): use whatever backend is available; ask only on ambiguity.
+2. Read the chosen backend's documentation for parameters and capabilities.
+3. If user requests a specific backend, honor it.
+
+## Generation Flow Template
+
+```markdown
+### Step N: Generate Images
+
+**Backend Selection**:
+1. Detect available image-generation tools/skills (runtime-native + installed)
+2. If one available → use it. If multiple → ask user once. If none → ask how to proceed.
+3. Read the chosen backend's docs for parameters
+
+**Generation Flow**:
+1. Write the full prompt to `prompts/NN-{type}-[slug].md` BEFORE invoking the backend
+2. Call backend with the prompt (or prompt file), output path, and parameters
+3. Generate sequentially by default (batch parallel only when backend supports it and user has multiple prompts)
+4. Output progress: "Generated X/N"
+5. On failure, auto-retry once before reporting error
+```
+
+**Batch Parallel** (`baoyu-image-gen` only): concurrent workers with per-provider throttling via `batch.max_workers` in EXTEND.md.
+
+## Output Path Convention
+
+**Output Directory**: `<skill-suffix>/<topic-slug>/`
+- `<skill-suffix>`: e.g., `xhs-images`, `cover-image`, `slide-deck`, `comic`
+- `<topic-slug>`: 2-4 words, kebab-case from content topic
+- Conflict: append timestamp `<topic-slug>-YYYYMMDD-HHMMSS`
+
+**Source Files**: Copy to output dir as `source-{slug}.{ext}`
+
+## Image Naming Convention
+
+**Format**: `NN-{type}-[slug].png`
+- `NN`: Two-digit sequence (01, 02, ...)
+- `{type}`: cover, content, page, slide, illustration, etc.
+- `[slug]`: 2-5 word kebab-case descriptor, unique within directory

+# ClawHub / OpenClaw Publishing
+
+## OpenClaw Metadata
+
+Skills include `metadata.openclaw` in YAML front matter:
+
+```yaml
+metadata:
+  openclaw:
+    homepage: https://github.com/JimLiu/baoyu-skills#<skill-name>
+    requires:          # only for skills with scripts
+      anyBins:
+        - bun
+        - npx
+```
+
+## Publishing Commands
+
+```bash
+bash scripts/sync-clawhub.sh           # sync all skills
+bash scripts/sync-clawhub.sh <skill>   # sync one skill
+```
+
+Release hooks are configured via `.releaserc.yml`. This repo does not stage a separate release directory: publish reads the skill directory directly and validates that local package references and CLI bin targets are self-contained.
+
+Every skill release must keep the `version:` in that skill's `SKILL.md` aligned with the version being published. `publish-skill.mjs` and `sync-clawhub.mjs` both reject mismatches so a registry payload cannot ship with stale skill metadata.
+
+Commits that touch `skills/<name>/**` must use Conventional Commit subjects, for example `fix(baoyu-post-to-wechat): handle WeChat editor focus`. CI runs `npm run verify:skill-release-commits` against the pushed or PR commit range so bare subjects like `Fix WeChat browser article publishing` cannot bypass per-skill release versioning silently.
+
+## Shared Workspace Packages
+
+`packages/` is the source of truth for shared runtime code. Most skills consume shared packages from npm with semver ranges. `baoyu-url-to-markdown` is the exception: it vendors the `baoyu-fetch` runtime into `skills/baoyu-url-to-markdown/scripts/lib/` so the published skill is self-contained and does not depend on the `baoyu-fetch` npm package.
+
+Current packages:
+- `baoyu-chrome-cdp` (Chrome CDP utilities), consumed by 5 skills (`baoyu-danger-gemini-web`, `baoyu-danger-x-to-markdown`, `baoyu-post-to-wechat`, `baoyu-post-to-weibo`, `baoyu-post-to-x`)
+- `baoyu-md` (shared Markdown rendering and placeholder pipeline), consumed by 3 skills (`baoyu-markdown-to-html`, `baoyu-post-to-wechat`, `baoyu-post-to-weibo`)
+- `baoyu-fetch` (URL-to-Markdown CLI), vendored into 1 skill (`baoyu-url-to-markdown`)
+
+**How it works**: npm packages are built from `packages/` and published to the public npm registry. Skills normally depend on those packages with `^<version>` specs. Release prep runs `node scripts/verify-shared-package-deps.mjs` so accidental `file:` dependencies cannot slip back in. For vendored skill runtimes, keep the copied code under the skill directory and run `node scripts/publish-skill.mjs --skill-dir <skill> --version <version> --dry-run` before publishing.
+
+**Update workflow**:
+1. Edit package under `packages/`
+2. Run the package build, e.g. `bun run --cwd packages/baoyu-md build`
+3. Publish the changed npm package with `npm publish --access public`
+4. Update consuming skill `package.json` semver ranges if the package version changed
+5. Run `node scripts/verify-shared-package-deps.mjs`
+
+**Git hook**: Run `node scripts/install-git-hooks.mjs` once to enable the `pre-push` hook. It blocks pushes when a skill uses a local `file:` dependency or a vendored workspace package.

+This repository has many scripts, but they do not share a single runtime or dependency graph. The lowest-risk testing strategy is to start from stable Node-based library code, then expand outward to CLI and skill-specific smoke tests.
+
+## Current Baseline
+
+- Root test runner: `node:test`
+- Entry point: `npm test`
+- Coverage command: `npm run test:coverage`
+- CI trigger: GitHub Actions on `push`, `pull_request`, and manual dispatch
+
+This avoids introducing Jest/Vitest across a repo that already mixes plain Node scripts, Bun-based skill packages, npm-published shared packages, and browser automation.
+
+## Rollout Plan
+
+### Phase 1: Stable library coverage
+
+Focus on pure functions under `scripts/lib/` first.
+
+- `scripts/lib/release-files.mjs`
+- `scripts/verify-shared-package-deps.mjs`
+
+Goals:
+
+- Validate file filtering and release packaging rules
+- Catch regressions that reintroduce local `file:` dependencies or vendored workspace packages
+- Keep tests deterministic and free of network, Bun, or browser requirements
+
+### Phase 2: Root CLI integration tests
+
+Add temp-directory integration tests for root CLIs that already support dry-run or local-only flows.
+
+- `scripts/verify-shared-package-deps.mjs`
+- `scripts/publish-skill.mjs --dry-run`
+- `scripts/sync-clawhub.mjs` argument handling and local skill discovery
+
+Goals:
+
+- Assert exit codes and stdout for common flows
+- Cover CLI argument parsing without hitting external services
+
+### Phase 3: Skill script smoke tests
+
+Add opt-in smoke tests for selected `skills/*/scripts/` packages, starting with those that:
+
+- accept local input files
+- have deterministic output
+- do not require authenticated browser sessions
+
+Examples:
+
+- markdown transforms
+- file conversion helpers
+- local content analyzers
+
+Keep browser automation, login flows, and live API publishing scripts outside the default CI path unless they are explicitly mocked.
+
+### Phase 4: Coverage gates
+
+After the stable Node path has enough breadth, add coverage thresholds in CI for the tested root modules.
+
+Recommended order:
+
+1. Start with reporting only
+2. Add line/function thresholds for `scripts/lib/**`
+3. Expand include patterns once skill-level smoke tests are reliable
+
+## Conventions For New Tests
+
+- Prefer temp directories over committed fixtures unless the fixture is reused heavily
+- Test exported functions before testing CLI wrappers
+- Avoid network, browser, and credential dependencies in default CI
+- Keep tests isolated so they can run with plain `node --test`

+# User Input Tools
+
+Skills in this repo are loaded by multiple agent runtimes (Claude Code, other agents, bare CLI). Each runtime exposes a different API for asking the user questions. This document defines the canonical **tool-selection rule** every skill follows so skills stay portable.
+
+## Tool Selection (priority order)
+
+1. **Prefer built-in user-input tools** if the current agent runtime exposes one — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
+2. **Fallback to plain text**: 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 rule**:
+   - If the tool supports **multiple questions per call** (e.g., `AskUserQuestion`): **Combine all applicable questions into a single call. Do NOT split into separate calls.**
+   - If the tool supports **only one question per call** (e.g., single-prompt `clarify`): ask **one question per call, in priority order**.
+
+## How Skills Declare This
+
+Each `SKILL.md` that uses interactive user input includes **exactly one** `## User Input Tools` section (typically near the top, right after the intro) that **inlines** this rule. Do NOT link here from a SKILL.md — skills are self-contained (see [CLAUDE.md → Skill Self-Containment](../CLAUDE.md)). This document is the author-side canonical source; copy its body into each SKILL.md. The rule then governs every user-input interaction in that skill and its `references/` files.
+
+Specific mentions of a concrete tool (e.g., `AskUserQuestion`) elsewhere in a skill are **concrete examples** — agents in other runtimes apply the rule above and substitute the local equivalent. Tool-specific parameters (e.g., `header:`, `multiSelect:`) are illustrative; runtimes without those knobs can omit them.

+# 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.

+# Changelog
+
+English | [简体中文](./CHANGELOG.zh-CN.md)
+
+The format is inspired by Keep a Changelog, and the project follows Semantic
+Versioning.
+
+## [0.1.2] - 2026-04-21
+
+#### Changed
+
+- Upgraded Defuddle to 0.17.0 and jsdom to 29.0.2 for generic extraction.
+- Added an `@xmldom/xmldom` override to keep the optional Defuddle MathML
+  dependency chain on a non-vulnerable release.
+
+#### Fixed
+
+- Fixed X/Twitter video extraction for single posts and X Articles by selecting
+  the highest-bitrate MP4 variant instead of the preview image URL.
+- Fixed X Article media rendering so video entities are emitted as
+  `[video](...)` links instead of image embeds.
+
+## [0.1.1] - 2026-03-27
+
+#### Added
+
+- Added the `hn` adapter for Hacker News stories and comment threads.
+- Added `--download-media` and `--media-dir` to download extracted media and
+  rewrite Markdown links.
+- Added Defuddle as the first generic extraction pass, with Readability +
+  HTML-to-Markdown as fallback.
+- Added interactive wait modes for login and verification flows, including
+  manual verification handoff and force-wait resume behavior.
+- Added `--format markdown|json` while keeping `--json` as a compatibility
+  alias.
+- Added Changesets-based release automation for npm publishing.
+
+#### Changed
+
+- Renamed the package and CLI from `baoyu-markdown` to `baoyu-fetch`.
+- Changed the published package to run `src/cli.ts` directly with Bun instead of
+  shipping a prebuilt `dist`.
+- Improved X extraction for threads, articles, note tweets, embeds, image URLs,
+  login state handling, and media metadata.
+- Improved YouTube transcript extraction and normalized Markdown image output.
+
+#### Fixed
+
+- Fixed X note tweet URL expansion.
+- Fixed media URL normalization before download, including Substack media links.
+- Fixed foreground behavior for interactive flows so manual steps are easier to
+  complete.
+
+## [0.1.0] - 2026-03-25
+
+#### Added
+
+- Initial public release as `baoyu-markdown`.
+- Added Chrome CDP session management, controlled tabs, and network journaling.
+- Added built-in adapters for `x`, `youtube`, and the generic fallback.
+- Added X article parsing, X single/tweet extraction, and YouTube transcript
+  extraction.
+- Added Markdown rendering, document metadata output, and CLI support for file
+  output, JSON output, debug exports, custom Chrome connection settings,
+  headless mode, and timeout control.

+# baoyu-fetch
+
+English | [简体中文](./README.zh-CN.md) | [Changelog](./CHANGELOG.md) | [中文更新日志](./CHANGELOG.zh-CN.md)
+
+`baoyu-fetch` is a Bun CLI built on Chrome CDP. Give it a URL and it returns
+high-quality `markdown` or `json`. When a site adapter matches, it prefers API
+responses or structured page data; otherwise it falls back to generic HTML
+extraction.
+
+## Features
+
+- Capture rendered page content through Chrome CDP
+- Observe network requests and responses, and fetch bodies when needed
+- Adapter registry that auto-selects a handler from the URL
+- Built-in adapters for `x`, `youtube`, and `hn`
+- Generic fallback: Defuddle first, then Readability + HTML-to-Markdown; when `--format markdown` is requested, it can also fall back to `defuddle.md`
+- Print `markdown` / `json` to stdout or save with `--output`
+- Optionally download extracted images or videos and rewrite Markdown links
+- Optional wait modes for login and verification flows
+- Chrome profile defaults to `baoyu-skills/chrome-profile`
+
+## Installation
+
+```bash
+bun install
+```
+
+For package usage, the quickest option is:
+
+```bash
+bunx baoyu-fetch https://example.com
+```
+
+You can also install it globally:
+
+```bash
+npm install -g baoyu-fetch
+```
+
+The npm package ships TypeScript source entrypoints instead of a prebuilt
+`dist`, so Bun is required at runtime.
+
+## Usage
+
+```bash
+bun run src/cli.ts https://example.com
+bunx baoyu-fetch https://example.com
+baoyu-fetch https://example.com
+baoyu-fetch https://example.com --format markdown --output article.md
+baoyu-fetch https://example.com --format markdown --output article.md --download-media
+baoyu-fetch https://x.com/jack/status/20 --format json --output article.json
+baoyu-fetch https://x.com/jack/status/20 --json
+baoyu-fetch https://x.com/jack/status/20 --wait-for interaction
+baoyu-fetch https://x.com/jack/status/20 --wait-for force
+baoyu-fetch https://x.com/jack/status/20 --chrome-profile-dir ~/Library/Application\\ Support/baoyu-skills/chrome-profile
+```
+
+## Options
+
+```bash
+baoyu-fetch <url> [options]
+
+Options:
+  --output <file>       Save output to file
+  --format <type>       Output format: markdown | json

+
+## How It Works
+
+1. The CLI parses the target URL and options.
+2. It opens or connects to a Chrome CDP session and creates a controlled tab.
+3. `NetworkJournal` records requests and responses.
+4. The adapter registry resolves a site-specific adapter when possible.
+5. The adapter returns a structured `ExtractedDocument`.
+6. If nothing matches, generic HTML extraction runs instead.
+7. The result is rendered as Markdown, or returned as JSON with both
+   `document` and `markdown`.
+
+## Development
+
+```bash
+bun run check
+bun run test
+bun run build
+```
+
+## Release
+
+When you make a user-visible change, add a changeset first:
+
+```bash
+bunx changeset
+```
+
+After the generated `.changeset/*.md` file lands on `main`, GitHub Actions will
+open or update the release PR. Merging that release PR publishes the package to
+npm.
+
+The publish flow does not build `dist`; it publishes `src/*.ts` for Bun
+execution directly.

+
+[English](./README.md) | 简体中文 | [更新日志](./CHANGELOG.zh-CN.md) | [English Changelog](./CHANGELOG.md)
+
+`baoyu-fetch` 是一个基于 Chrome CDP 的 Bun CLI。输入 URL，它会输出高质量
+`markdown` 或 `json`；命中站点 adapter 时优先消费 API 返回或页面内结构化
+数据，未命中时回退到通用 HTML 提取。
+
+## 当前能力
+
+- 通过 Chrome CDP 抓取渲染后的页面内容
+- 监听网络请求与响应，按需拉取响应体
+- adapter registry，支持按 URL 自动命中站点处理器
+- 内置 `x`、`youtube`、`hn` adapters
+- 通用 fallback：Defuddle 优先，Readability + HTML to Markdown 回退；`--format markdown` 时会再尝试 `defuddle.md` 兜底
+- `stdout` 或 `--output` 输出 `markdown` / `json`
+- 可选下载提取出的图片/视频并重写 Markdown 链接
+- 提供登录/验证场景下的交互等待模式
+- Chrome profile 默认对齐 `baoyu-skills/chrome-profile`
+
+## 安装
+
+```bash
+bun install
+```
+
+作为包使用时，推荐直接这样运行：
+
+```bash
+bunx baoyu-fetch https://example.com
+```
+
+也可以全局安装：
+
+```bash
+npm install -g baoyu-fetch
+```
+
+npm 包发布的是 TypeScript 源码入口，不包含预编译的 `dist`，所以运行时需要
+Bun。
+
+## 用法
+
+```bash
+bun run src/cli.ts https://example.com
+bunx baoyu-fetch https://example.com
+baoyu-fetch https://example.com
+baoyu-fetch https://example.com --format markdown --output article.md
+baoyu-fetch https://example.com --format markdown --output article.md --download-media
+baoyu-fetch https://x.com/jack/status/20 --format json --output article.json
+baoyu-fetch https://x.com/jack/status/20 --json
+baoyu-fetch https://x.com/jack/status/20 --wait-for interaction
+baoyu-fetch https://x.com/jack/status/20 --wait-for force
+baoyu-fetch https://x.com/jack/status/20 --chrome-profile-dir ~/Library/Application\\ Support/baoyu-skills/chrome-profile
+```
+
+## 主要参数
+
+```bash
+baoyu-fetch <url> [options]
+
+Options:
+  --output <file>       保存输出内容到文件
+  --format <type>       输出格式：markdown | json
+  --json                `--format json` 的兼容别名
+  --adapter <name>      强制使用指定 adapter（如 x / hn / generic）
+  --download-media      下载 adapter 返回的媒体到 ./imgs 和 ./videos，并重写 markdown 链接
+  --media-dir <dir>     指定媒体下载根目录；默认使用输出文件所在目录
+  --debug-dir <dir>     导出调试信息（html、document.json、network.json）
+  --cdp-url <url>       连接现有 Chrome 调试地址
+  --browser-path <path> 指定 Chrome 可执行文件
+  --chrome-profile-dir <path>
+                        指定 Chrome profile 目录。默认使用 BAOYU_CHROME_PROFILE_DIR，
+                        否则回退到 baoyu-skills/chrome-profile
+  --headless            启动临时 headless Chrome（未连现有实例时）
+  --wait-for <mode>     等待模式：interaction | force
+  --wait-for-interaction
+                        `--wait-for interaction` 的别名
+  --wait-for-login      `--wait-for interaction` 的别名
+  --interaction-timeout <ms>
+                        手动交互等待超时，默认 600000
+  --interaction-poll-interval <ms>
+                        等待期间的轮询间隔，默认 1500
+  --login-timeout <ms>  `--interaction-timeout` 的别名
+  --login-poll-interval <ms>
+                        `--interaction-poll-interval` 的别名
+  --timeout <ms>        页面加载超时，默认 30000
+  --help                显示帮助
+```
+
+## 设计
+
+核心链路：
+
+1. CLI 解析 URL 和选项
+2. 建立 CDP 会话并创建受控 tab
+3. 启动 `NetworkJournal` 收集所有请求/响应
+4. 由 adapter registry 匹配站点 adapter
+5. adapter 返回结构化 `ExtractedDocument`
+6. 没命中则走通用 HTML 提取
+7. 按请求输出 Markdown，或输出包含 `document` 和 `markdown` 的 JSON
+
+## 开发
+
+```bash
+bun run check
+bun run test
+bun run build
+```
+
+## 发版
+
+新增用户可见改动后，先添加一个 changeset：
+
+```bash
+bunx changeset
+```
+
+把生成的 `.changeset/*.md` 一起合并到 `main` 后，GitHub Actions 会自动创建或
+更新 release PR；合并 release PR 之后，会自动发布到 npm。
+
+发布流程不会编译 `dist`，而是直接把 `src/*.ts` 发布出去供 Bun 执行。
