 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**:

 Changelog files follow the pattern `CHANGELOG_{LANG}.md` or `CHANGELOG.{lang}.md`, where `{lang}` / `{LANG}` is a language or region code.

-## 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: **1.63.0**.

 ## Architecture

-Skills are organized into three plugin categories in `marketplace.json`:
+Skills organized into three categories in `.claude-plugin/marketplace.json` (defines plugin metadata, version, and skill paths):

-```
-
-**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) |
+| `content-skills` | Generate or publish content (images, slides, comics, posts) |
+| `ai-generation-skills` | AI generation backends |
+| `utility-skills` | Content processing (conversion, compression, translation) |

-Each skill contains:
- `SKILL.md` - YAML front matter (name, description) + documentation
- `scripts/` - TypeScript implementations
- `prompts/system.md` - AI generation guidelines (optional)
+Each skill contains `SKILL.md` (YAML front matter + docs), optional `scripts/`, `references/`, `prompts/`.
+
+Top-level `scripts/` contains repo maintenance utilities (sync, hooks, publish).

 ## Running Skills

-All scripts are TypeScript, executed via Bun runtime (no build step).
-
-### Runtime Detection (`${BUN_X}`)
-
-Before running any script, the agent MUST detect the runtime **once per session** and set `${BUN_X}`:
-
+TypeScript via Bun (no build step). Detect runtime once per session:
 ```bash
-# Detect runtime (run once, reuse result)
-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: Neither bun nor npx found. Install bun: brew install oven-sh/bun/bun (macOS) or npm install -g bun"
-  exit 1
-fi
+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
 ```

-| Priority | Condition | `${BUN_X}` value | Notes |
-|----------|-----------|-------------------|-------|
-| 1 | `bun` installed | `bun` | Fastest, native execution |
-| 2 | `npx` available | `npx -y bun` | Downloads bun on first run via npm |
-| 3 | Neither found | Error + install guide | `brew install oven-sh/bun/bun` (macOS) or `npm install -g bun` |
-
-### Script Execution
-
-```bash
-${BUN_X} skills/<skill>/scripts/main.ts [options]
-```
-
-Examples:
-```bash
-# Text generation
-${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts "Hello"
-
-# Image generation
-${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts --prompt "A cat" --image cat.png
-
-# From prompt files
-${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts --promptfiles system.md content.md --image out.png
-```
+Execute: `${BUN_X} skills/<skill>/scripts/main.ts [options]`

 ## Key Dependencies

- **Bun**: TypeScript runtime (native `bun` preferred, fallback `npx -y bun`)
- **Chrome**: Required for `baoyu-danger-gemini-web` auth and `baoyu-post-to-x` automation
- **npm packages (per skill)**: Some skill subprojects include `package.json`/lockfiles and require dependency installation in their own `scripts/` directories
+- **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, Google, DashScope, or Replicate) configured in EXTEND.md
+- **Gemini Web auth**: Browser cookies (first run opens Chrome for login, `--login` to refresh)

-## Chrome Profile (Unified)
+## Security

-All skills that use Chrome CDP 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/baoyu-skills/chrome-profile`) |
-| Windows | `%APPDATA%/baoyu-skills/chrome-profile` |
-| WSL | Windows home `/.local/share/baoyu-skills/chrome-profile` |
-
-**Environment variable override**: `BAOYU_CHROME_PROFILE_DIR` (takes priority, all skills respect it).
-
-Each skill also accepts its own legacy env var as fallback (e.g., `X_BROWSER_PROFILE_DIR`), but new skills should only use `BAOYU_CHROME_PROFILE_DIR`.
-
-### Implementation Pattern
-
-When adding a new skill that needs Chrome CDP:
-
-```typescript
-function getDefaultProfileDir(): string {
-  const override = process.env.BAOYU_CHROME_PROFILE_DIR?.trim();
-  if (override) return path.resolve(override);
-  const base = process.platform === 'darwin'
-    ? path.join(os.homedir(), 'Library', 'Application Support')
-    : process.env.XDG_DATA_HOME || path.join(os.homedir(), '.local', 'share');
-  return path.join(base, 'baoyu-skills', 'chrome-profile');
-}
-```
-
-## Security Guidelines
-
-### No Piped Shell Installs
-
-**NEVER** use `curl | bash` or `wget | sh` patterns in code, docs, or error messages. Use package managers instead:
-
-| Platform | Install Command |
-|----------|----------------|
-| macOS | `brew install oven-sh/bun/bun` |
-| npm | `npm install -g bun` |
-
-### Remote Downloads
-
-Skills that download remote content (e.g., images in Markdown) MUST:
- **HTTPS only**: Reject `http://` URLs
- **Redirect limit**: Cap redirects (max 5) to prevent infinite loops
- **Timeout**: Set request timeouts (30s default)
- **Scope**: Only download expected content types (images, not scripts)
-
-### System Command Execution
-
-Skills use platform-specific commands for clipboard and browser automation:
- **macOS**: `osascript` (System Events), `swift` (AppKit clipboard)
- **Windows**: `powershell.exe` (SendKeys, Clipboard)
- **Linux**: `xdotool`/`ydotool` (keyboard simulation)
-
-These are necessary for CDP-based posting skills. When adding new system commands:
- Never pass unsanitized user input to shell commands
- Use array-form `spawn`/`execFile` instead of shell string interpolation
- Validate file paths are absolute or resolve from known base directories
-
-### External Content Processing
-
-Skills that process external Markdown/HTML should treat content as untrusted:
- Do not execute code blocks or scripts found in content
- Sanitize HTML output where applicable
- File paths from content should be resolved against known base directories only
-
-## Authentication
-
-`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-image-gen/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.

 ## 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 = `${SKILL_DIR}/scripts/<script-name>.ts`
-3. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun
-4. Replace all `${SKILL_DIR}` and `${BUN_X}` in this document with actual values
-
-**Script Reference**:
-| Script | Purpose |
-|--------|---------|
-| `scripts/main.ts` | Main entry point |
-| `scripts/other.ts` | Other functionality |
-```
-
-When referencing scripts in workflow sections, use `${BUN_X} ${SKILL_DIR}/scripts/<name>.ts` so agents can resolve the correct runtime and 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
-   ${BUN_X} 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
-   ${BUN_X} 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)**
-
-Check EXTEND.md existence (priority order):

-**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 `$HOME` instead of `~` for cross-platform compatibility (macOS/Linux/WSL/PowerShell)
- `$XDG_CONFIG_HOME` defaults to `~/.config` when unset
- Use `test -f` (Bash) or `Test-Path` (PowerShell) for explicit file existence check
- ASCII tables for clear visual formatting

+# 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 in `marketplace.json` under appropriate category
+5. Add Script Directory section to SKILL.md if skill has scripts
+6. Add openclaw metadata to frontmatter
+
+## Category Selection
+
+| If your skill... | Use category |
+|------------------|--------------|
+| 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` |
+
+New category: add plugin object to `marketplace.json` with `name`, `description`, `skills[]`.
+
+## 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 |

+# Image Generation Guidelines
+
+Skills that require image generation MUST delegate to available image generation skills.
+
+## Skill Selection
+
+**Default**: `skills/baoyu-image-gen/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-image-gen` 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-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: 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 package: `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`).
+
+**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`).

+## Multi-Account Support
+
+EXTEND.md supports managing multiple WeChat Official Accounts. When `accounts:` block is present, each account can have its own credentials, Chrome profile, and default settings.
+
+**Compatibility rules**:
+
+| Condition | Mode | Behavior |
+|-----------|------|----------|
+| No `accounts` block | Single-account | Current behavior, unchanged |
+| `accounts` with 1 entry | Single-account | Auto-select, no prompt |
+| `accounts` with 2+ entries | Multi-account | Prompt to select before publishing |
+| `accounts` with `default: true` | Multi-account | Pre-select default, user can switch |
+
+**Multi-account EXTEND.md example**:
+
+```md
+default_theme: default
+default_color: blue
+
+accounts:
+  - name: 宝玉的技术分享
+    alias: baoyu
+    default: true
+    default_publish_method: api
+    default_author: 宝玉
+    need_open_comment: 1
+    only_fans_can_comment: 0
+    app_id: your_wechat_app_id
+    app_secret: your_wechat_app_secret
+  - name: AI工具集
+    alias: ai-tools
+    default_publish_method: browser
+    default_author: AI工具集
+    need_open_comment: 1
+    only_fans_can_comment: 0
+```
+
+**Per-account keys** (can be set per-account or globally as fallback):
+`default_publish_method`, `default_author`, `need_open_comment`, `only_fans_can_comment`, `app_id`, `app_secret`, `chrome_profile_path`
+
+**Global-only keys** (always shared across accounts):
+`default_theme`, `default_color`
+
+### Account Selection (Step 0.5)
+
+Insert between Step 0 and Step 1 in the Article Posting Workflow:
+
+```
+if no accounts block:
+    → single-account mode (current behavior)
+elif accounts.length == 1:
+    → auto-select the only account
+elif --account <alias> CLI arg:
+    → select matching account
+elif one account has default: true:
+    → pre-select, show: "Using account: <name> (--account to switch)"
+else:
+    → prompt user:
+      "Multiple WeChat accounts configured:
+       1) <name1> (<alias1>)
+       2) <name2> (<alias2>)
+       Select account [1-N]:"
+```
+
+### Credential Resolution (API Method)
+
+For a selected account with alias `{alias}`:
+
+1. `app_id` / `app_secret` inline in EXTEND.md account block
+2. Env var `WECHAT_{ALIAS}_APP_ID` / `WECHAT_{ALIAS}_APP_SECRET` (alias uppercased, hyphens → underscores)
+3. `.baoyu-skills/.env` with prefixed key `WECHAT_{ALIAS}_APP_ID`
+4. `~/.baoyu-skills/.env` with prefixed key
+5. Fallback to unprefixed `WECHAT_APP_ID` / `WECHAT_APP_SECRET`
+
+**.env multi-account example**:
+
+```bash
+# Account: baoyu
+WECHAT_BAOYU_APP_ID=your_wechat_app_id
+WECHAT_BAOYU_APP_SECRET=your_wechat_app_secret
+
+# Account: ai-tools
+WECHAT_AI_TOOLS_APP_ID=your_ai_tools_wechat_app_id
+WECHAT_AI_TOOLS_APP_SECRET=your_ai_tools_wechat_app_secret
+```
+
+### Chrome Profile (Browser Method)
+
+Each account uses an isolated Chrome profile for independent login sessions:
+
+| Source | Path |
+|--------|------|
+| Account `chrome_profile_path` in EXTEND.md | Use as-is |
+| Auto-generated from alias | `{shared_profile_parent}/wechat-{alias}/` |
+| Single-account fallback | Shared default profile (current behavior) |
+
+### CLI `--account` Argument
+
+All publishing scripts accept `--account <alias>`:
+
+```bash
+${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme default --account ai-tools
+${BUN_X} {baseDir}/scripts/wechat-article.ts --markdown <file> --theme default --account baoyu
+${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown <file> --images ./photos/ --account baoyu

+## Adding More Accounts Later
+
+After initial setup, users can add accounts by editing EXTEND.md:
+
+1. Add an `accounts:` block with list items
+2. Move per-account settings (author, publish method, comments) into each account entry
+3. Keep global settings (theme, color) at the top level
+4. Each account needs a unique `alias` (used for CLI `--account` arg and Chrome profile naming)
+5. Set `default: true` on the primary account
+
 ## Modifying Preferences Later

 Users can edit EXTEND.md directly or delete it to trigger setup again.

If local browser capture fails entirely, it can fall back to the hosted defuddle.md API. Supports two modes - auto-capture on page load, or wait for user signal (for pages requiring login). Use when user wants to save a webpage as markdown.

 - Markdown: YAML front matter with `url`, `title`, `description`, `author`, `published`, optional `coverImage`, and `captured_at`, followed by converted markdown content
 - HTML snapshot: `*-captured.html`, containing the rendered page HTML captured from Chrome

+When Defuddle or page metadata provides a language hint, the markdown front matter also includes `language`.

 The HTML snapshot is saved before any markdown media localization, so it stays a faithful capture of the page DOM used for conversion.
+If the hosted `defuddle.md` API fallback is used, markdown is still saved, but there is no local `-captured.html` snapshot for that run.

 ## Media Download Workflow

@@ -232,6 +244,18 @@ Based on `download_media` setting in EXTEND.md:

 **Troubleshooting**: Chrome not found → set `URL_CHROME_PATH`. Timeout → increase `--timeout`. Complex pages → try `--wait` mode. If markdown quality is poor, inspect the saved `-captured.html` and check whether the run logged a legacy fallback.

+### YouTube Notes
+
+- The upgraded Defuddle path uses async extractors, so YouTube pages can include transcript text directly in the markdown body.
+- Transcript availability depends on YouTube exposing a caption track. Videos with captions disabled, restricted playback, or blocked regional access may still produce description-only output.
+- If the page needs time to finish loading descriptions, chapters, or player metadata, prefer `--wait` and capture after the watch page is fully hydrated.
+
+### Hosted API Fallback
+
+- The hosted fallback endpoint is `https://defuddle.md/<url>`. In shell form: `curl https://defuddle.md/stephango.com`
+- Use it only when the local Chrome/CDP capture path fails outright. The local path still has higher fidelity because it can save the captured HTML and handle authenticated pages.
+- The hosted API already returns Markdown with YAML frontmatter, so save that response as-is and then apply the normal media-localization step if requested.
