CLAUDE.md

Claude Code marketplace plugin providing AI-powered content generation skills. Version: 2.0.0.

Architecture

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:

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

TypeScript via Bun (no build step). Detect runtime once per session:

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

Execute: ${BUN_X} skills/<skill>/scripts/main.ts [options]

Key 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
• 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)

Security

• 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

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; 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; 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 so it follows the same workspace layout as other shared packages.

Invoke via (TS entrypoint with #!/usr/bin/env bun shebang):

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.

Release Process

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

Code Style

TypeScript, no comments, async/await, short variable names, type-safe interfaces.

Adding New Skills

All skills MUST use baoyu- prefix. Details: docs/creating-skills.md
