User Input Tools When this skill prompts the user, follow this tool-selection rule (priority order): Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion , request_user_input , clarify , ask_user , or any equivalent. 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. Batching : if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order. Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes. Script Directory Agent Execution : Determine this SKILL.md directory as {baseDir} . Resolve ${BUN_X} runtime: if bun installed → bun ; if npx available → npx -y bun ; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values. Script Purpose scripts/main.ts Main entry point Preferences (EXTEND.md) Check EXTEND.md in priority order — the first one found wins: Priority Path Scope 1 .baoyu-skills/baoyu-markdown-to-html/EXTEND.md Project 2 ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-markdown-to-html/EXTEND.md XDG 3 $HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.md User home If none found, use defaults. EXTEND.md supports : default theme, custom CSS variables, code block style, mermaid defaults ( mermaid_theme , mermaid_scale , mermaid_background ). Workflow Step 0: Pre-check (Chinese Content) Condition : Only execute if input file contains Chinese text. Detection : Read input markdown file Check if content contains CJK characters (Chinese/Japanese/Korean) If no CJK content → skip to Step 1 Format Suggestion : If CJK content detected AND baoyu-format-markdown skill is available: Use AskUserQuestion to ask whether to format first. Formatting can fix: Bold markers with punctuation inside causing ** parse failures CJK/English spacing issues If user agrees : Invoke baoyu-format-markdown skill to format the file, then use formatted file as input. If user declines : Continue with original file. Step 1: Determine Theme Theme resolution order (first match wins): User explicitly specified theme (CLI --theme or conversation) EXTEND.md default_theme (this skill's own EXTEND.md, checked in Step 0) baoyu-post-to-wechat EXTEND.md default_theme (cross-skill fallback) If none found → use AskUserQuestion to confirm Cross-skill EXTEND.md check (only if this skill's EXTEND.md has no default_theme ): Read $HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md if it exists and look for a default_theme: line. Use the value if present; otherwise fall through. If theme is resolved from EXTEND.md : Use it directly, do NOT ask the user. If no default found : use AskUserQuestion to confirm a theme from the Themes table below. Step 1.5: Determine Citation Mode Default : Off. Do not ask by default. Enable only if the user explicitly asks for "微信外链转底部引用", "底部引用", "文末引用", or passes --cite . Behavior when enabled : Ordinary external links are rendered with numbered superscripts and collected under a final 引用链接 section. https://mp.weixin.qq.com/... links stay as direct links and are not moved to the bottom. Bare links where link text equals URL stay inline. Step 2: Convert ${BUN_X} {baseDir}/scripts/main.ts <markdown_file> --theme <theme> [--cite] Step 3: Report Result Display the output path from JSON result. If backup was created, mention it.

Input: /path/to/article.md Output: /path/to/article.html Conflict handling : If HTML file already exists, it will be backed up first: Backup: /path/to/article.html.bak-YYYYMMDDHHMMSS JSON output to stdout: { "title" : "Article Title" , "author" : "Author Name" , "summary" : "Article summary..." , "htmlPath" : "/path/to/article.html" , "backupPath" : "/path/to/article.html.bak-20260128180000" , "contentImages" : [ { "placeholder" : "MDTOHTMLIMGPH_1" , "localPath" : "/path/to/img.png" , "originalPath" : "imgs/image.png" } ] , "mermaidImages" : [ { "hash" : "a1b2c3d4e5f6" , "localPath" : "/path/to/imgs/.mermaid-cache/mermaid-a1b2c3d4e5f6.png" , "cached" : false } ] } Mermaid rendering : Code blocks fenced as ```mermaid are rendered to PNGs via headless Chrome (CDP) and cached at imgs/.mermaid-cache/mermaid-<hash>.png . The cache key includes the code, theme, scale, target width, background, and mermaid version. Add imgs/.mermaid-cache/ to .gitignore if you do not want generated diagrams checked in. Requires Chrome/Chromium/Edge on the system; otherwise the block falls back to <pre class="mermaid">…</pre> and conversion still succeeds.
