URL to Markdown

Fetches any URL via baoyu-fetch CLI (Chrome CDP + site-specific adapters) and converts it to clean markdown.

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.

CLI Setup

Important: The CLI source is vendored in {baseDir}/scripts/lib. scripts/package.json installs only third-party runtime dependencies.

Agent Execution Instructions:

Determine this SKILL.md file's directory path as {baseDir}
Resolve ${BUN} runtime: if bun installed → bun; else suggest installing Bun
If {baseDir}/scripts/node_modules does not exist, run ${BUN} install --cwd {baseDir}/scripts
${READER} = {baseDir}/scripts/baoyu-fetch
Replace all ${READER} in this document with the resolved value

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:

Priority	Path	Scope
1	`.baoyu-skills/baoyu-url-to-markdown/EXTEND.md`	Project
2	`${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-url-to-markdown/EXTEND.md`	XDG
3	`$HOME/.baoyu-skills/baoyu-url-to-markdown/EXTEND.md`	User home

Result	Action
Found	Read, parse, apply settings
Not found	MUST run first-time setup (see below) — do NOT silently create defaults
