 1. Check for `.releaserc.yml` (optional config override)

    - `package.json` (Node.js)
    - `pyproject.toml` (Python)
@@ -48,18 +49,46 @@ Just run `/release-skills` - auto-detects your project configuration.
 4. Identify language of each changelog by filename suffix
 5. 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).

 # CLAUDE.md
 
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## 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: **1.90.0**.
 
 ## 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:
 
-```
-skills/
-├── [content-skills]           # Content generation and publishing
-│   ├── baoyu-xhs-images/          # Xiaohongshu infographic series (1-10 images)
-│   ├── baoyu-cover-image/         # Article cover images (2.35:1 aspect)
-│   ├── baoyu-slide-deck/          # Presentation slides with outlines
-│   ├── baoyu-article-illustrator/ # Smart illustration placement
-│   ├── baoyu-comic/               # Knowledge comics (Logicomix/Ohmsha style)
-│   ├── baoyu-post-to-x/           # X/Twitter posting automation
-│   └── baoyu-post-to-wechat/      # WeChat Official Account posting
-│
-├── [ai-generation-skills]     # AI-powered generation backends
-│   └── baoyu-danger-gemini-web/   # Gemini API wrapper (text + image gen)
-│
-└── [utility-skills]           # Utility tools for content processing
-    ├── baoyu-danger-x-to-markdown/ # X/Twitter content to markdown
-    └── baoyu-compress-image/      # Image compression
-```
+| Group | Description |
+|-------|-------------|
+| Content Skills | Generate or publish content (images, slides, comics, posts) |
+| AI Generation Skills | AI generation backends |
+| Utility Skills | Content processing (conversion, compression, translation) |
 
-**Plugin Categories**:
-| Category | Description |
-|----------|-------------|
-| `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
-
-# From prompt files
-npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts --promptfiles system.md content.md --image out.png
-```
+Execute: `${BUN_X} skills/<skill>/scripts/main.ts [options]`
 
 ## Key Dependencies
 
-- **Bun**: TypeScript runtime (via `npx -y bun`)
-- **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-imagine` 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 `skills/baoyu-imagine/SKILL.md` unless user specifies otherwise |
 
-**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.
+
+## Deprecated Skills
+
+| Skill | Note |
+|-------|------|
+| `baoyu-image-gen` | Migrated to `baoyu-imagine`. Do NOT add to `.claude-plugin/marketplace.json`. Do NOT update README for this skill. |
 
 ## 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:
+1. `CHANGELOG.md` + `CHANGELOG.zh.md`
 2. `marketplace.json` version bump
 3. `README.md` + `README.zh.md` if applicable
 4. All files committed together before tag
 
-## 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"
-\`\`\`

-
-### 2. Extension Support Section (at the end)
-
-Simplified section that references the preferences section:
-
-```markdown

+
+This repository now supports publishing each `skills/baoyu-*` directory as an individual ClawHub skill.
+
+```bash
+# Preview what would be published
+./scripts/sync-clawhub.sh --dry-run
+
+# Publish all changed skills from ./skills
+./scripts/sync-clawhub.sh --all

+ClawHub installs skills individually, not as one marketplace bundle. After publishing, users can install specific skills such as:
+
+```bash
+clawhub install baoyu-imagine
+clawhub install baoyu-markdown-to-html
+```
+
+Publishing to ClawHub releases the published skill under `MIT-0`, per ClawHub's registry rules.

+**Provider Notes**:
+- Azure OpenAI: `--model` means Azure deployment name, not the underlying model family.
+- DashScope: `qwen-image-2.0-pro` is the recommended default for custom `--size`, `21:9`, and strong Chinese/English text rendering.
+- 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.

+# Chrome Profile
+
+All CDP skills share a single profile directory. Do NOT create per-skill profiles.
+
+Override: `BAOYU_CHROME_PROFILE_DIR` env var (takes priority over all defaults).
+
+| 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` |
+| WSL | Windows home `/.local/share/baoyu-skills/chrome-profile` |
+
+New skills: use `BAOYU_CHROME_PROFILE_DIR` only (not per-skill env vars like `X_BROWSER_PROFILE_DIR`).
+
+## Implementation Pattern
+
+```typescript
+function getDefaultProfileDir(): string {
+  const override = process.env.BAOYU_CHROME_PROFILE_DIR?.trim();
+  if (override) return path.resolve(override);
+  const base = process.platform === 'darwin'

+# Style Maintenance (baoyu-comic)
+
+## Adding a New Style
+
+1. Create style definition: `skills/baoyu-comic/references/styles/<style-name>.md`
+2. Update SKILL.md: add to `--style` options table + auto-selection entry
+3. Generate showcase image:
+   ```bash
+   ${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts \
+     --prompt "A single comic book page in <style-name> style showing [scene]. Features: [characteristics]. 3:4 portrait aspect ratio comic page." \
+     --image screenshots/comic-styles/<style-name>.png
+   ```
+4. Compress: `${BUN_X} skills/baoyu-compress-image/scripts/main.ts screenshots/comic-styles/<style-name>.png`
+5. Update both READMEs (`README.md` + `README.zh.md`): add style to options, description table, preview grid
+
+## Updating an Existing Style
+
+1. Update style definition in `references/styles/`
+2. Regenerate showcase image if visual characteristics changed (steps 3-4 above)
+3. Update READMEs if description changed
+
+## Deleting a Style
+
+1. Delete style definition + showcase image (`.webp`)
+2. Remove from SKILL.md `--style` options + auto-selection
+3. Remove from both READMEs (options, description table, preview grid)
+
+## Style Preview Grid Format
+

+# 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 |
+```
+
+## Progressive Disclosure
+
+For skills with extensive content:
+
+```
+skills/baoyu-example/
+├── SKILL.md              # Main instructions (<500 lines)
+├── references/
+│   ├── styles.md         # Loaded as needed
+│   └── examples.md       # Loaded as needed
+└── scripts/
+    └── main.ts
+```
+
+Link from SKILL.md (one level deep only):
+```markdown
+**Available styles**: See [references/styles.md](references/styles.md)
+```
+
+## Extension Support (EXTEND.md)
+
+Every SKILL.md MUST include EXTEND.md loading. Add as Step 1.1 (workflow skills) or "Preferences" section (utility skills):
+
+```markdown
+**1.1 Load Preferences (EXTEND.md)**
+
+Check EXTEND.md existence (priority order):
+
+\`\`\`bash
+test -f .baoyu-skills/<skill-name>/EXTEND.md && echo "project"
+test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/<skill-name>/EXTEND.md" && echo "xdg"
+test -f "$HOME/.baoyu-skills/<skill-name>/EXTEND.md" && echo "user"
+\`\`\`
+
+| Path | Location |
+|------|----------|
+| `.baoyu-skills/<skill-name>/EXTEND.md` | Project directory |
+| `$XDG_CONFIG_HOME/baoyu-skills/<skill-name>/EXTEND.md` | XDG config (~/.config) |
+| `$HOME/.baoyu-skills/<skill-name>/EXTEND.md` | User home (legacy) |
+
+| Result | Action |
+|--------|--------|
+| Found | Read, parse, display summary |
+| Not found | Ask user with AskUserQuestion |
+```
+
+End of SKILL.md should include:
+```markdown
+## Extension Support
+Custom configurations via EXTEND.md. See **Step 1.1** for paths and supported options.

+# Image Generation Guidelines
+
+Skills that require image generation MUST delegate to available image generation skills.
+
+## Skill Selection
+
+**Default**: `skills/baoyu-imagine/SKILL.md` (unless user specifies otherwise).
+
+1. Read skill's SKILL.md for parameters and capabilities
+2. If user requests different skill, check `skills/` for alternatives
+3. Only ask user when multiple viable options exist
+
+## Generation Flow Template
+
+```markdown
+### Step N: Generate Images
+
+**Skill Selection**:
+1. Check available skills (`baoyu-imagine` default, or `baoyu-danger-gemini-web`)
+2. Read selected skill's SKILL.md for parameters
+3. If multiple skills available, ask user to choose
+
+**Generation Flow**:
+1. Call skill with prompt, output path, and skill-specific parameters
+2. Generate sequentially by default (batch parallel only when user has multiple prompts)
+3. Output progress: "Generated X/N"
+4. On failure, auto-retry once before reporting error
+```
+
+**Batch Parallel** (`baoyu-imagine` 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: release prep only syncs `packages/` into each skill's committed `scripts/vendor/`, and publish reads the skill directory directly.
+
+## Shared Workspace Packages
+
+`packages/` is the **only** source of truth. Never edit `skills/*/scripts/vendor/` directly.
+
+Current packages:
+- `baoyu-chrome-cdp` (Chrome CDP utilities), consumed by 6 skills (`baoyu-danger-gemini-web`, `baoyu-danger-x-to-markdown`, `baoyu-post-to-wechat`, `baoyu-post-to-weibo`, `baoyu-post-to-x`, `baoyu-url-to-markdown`)
+- `baoyu-md` (shared Markdown rendering and placeholder pipeline), consumed by 3 skills (`baoyu-markdown-to-html`, `baoyu-post-to-wechat`, `baoyu-post-to-weibo`)
+
+**How it works**: Sync script copies packages into each consuming skill's `vendor/` directory and rewrites dependency specs to `file:./vendor/<name>`. Vendor copies are committed to git, making skills self-contained.
+
+**Update workflow**:
+1. Edit package under `packages/`
+2. Run `node scripts/sync-shared-skill-packages.mjs`
+3. Commit synced `vendor/`, `package.json`, and `bun.lock` together
+
+**Git hook**: Run `node scripts/install-git-hooks.mjs` once to enable the `pre-push` hook. It re-syncs and blocks push if vendor copies are stale (`--enforce-clean`).

+# Testing Strategy
+
+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, vendored code, and browser automation.
+
+## Rollout Plan
+
+### Phase 1: Stable library coverage
+
+Focus on pure functions under `scripts/lib/` first.
+
+- `scripts/lib/release-files.mjs`
+- `scripts/lib/shared-skill-packages.mjs`
+
+Goals:
+
+- Validate file filtering and release packaging rules
+- Catch regressions in package vendoring and dependency rewriting
+- 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/sync-shared-skill-packages.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`

+# 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
+  --json                Alias for --format json
+  --adapter <name>      Force an adapter (for example x / hn / generic)
+  --download-media      Download adapter-reported media into ./imgs and ./videos, then rewrite markdown links
+  --media-dir <dir>     Base directory for downloaded media. Defaults to the output directory
+  --debug-dir <dir>     Write debug artifacts (html, document.json, network.json)
+  --cdp-url <url>       Reuse an existing Chrome DevTools endpoint
+  --browser-path <path> Explicit Chrome binary path
+  --chrome-profile-dir <path>
+                        Chrome user data dir. Defaults to BAOYU_CHROME_PROFILE_DIR
+                        or baoyu-skills/chrome-profile
+  --headless            Launch a temporary headless Chrome if needed
+  --wait-for <mode>     Wait mode: interaction | force
+  --wait-for-interaction
+                        Alias for --wait-for interaction
+  --wait-for-login      Alias for --wait-for interaction
+  --interaction-timeout <ms>
+                        Manual interaction timeout. Default: 600000
+  --interaction-poll-interval <ms>
+                        Poll interval while waiting. Default: 1500
+  --login-timeout <ms>  Alias for --interaction-timeout
+  --login-poll-interval <ms>
+                        Alias for --interaction-poll-interval
+  --timeout <ms>        Page load timeout. Default: 30000
+  --help                Show help
+```
+
+## 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.

+# baoyu-fetch
+
+[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）

+## 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。
