# 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):
1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
2. **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.
3. **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**:
1. Determine this SKILL.md file's directory path as `{baseDir}`
2. Resolve `${BUN}` runtime: if `bun` installed → `bun`; else suggest installing Bun
3. If `{baseDir}/scripts/node_modules` does not exist, run `${BUN} install --cwd {baseDir}/scripts`
4. `${READER}` = `{baseDir}/scripts/baoyu-fetch`
5. Replace all `${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 |
**EXTEND.md supports**: download media by default, default output directory.
### First-Time Setup ⛔ BLOCKING
When EXTEND.md is not found, you **MUST** use `AskUserQuestion` to gather preferences before creating EXTEND.md. **NEVER** create EXTEND.md with silent defaults. Generation is BLOCKED until setup completes. Batch all three questions into a single call:
- **Q1 — Media** (header "Media"): "How to handle images and videos in pages?"
- "Ask each time (Recommended)" — Prompt after each save
- "Always download" — Download to local `imgs/` and `videos/`
- "Never download" — Keep remote URLs
- **Q2 — Output** (header "Output"): "Default output directory?"
- "url-to-markdown (Recommended)" — Save to `./url-to-markdown/{domain}/{slug}.md`
- User may pick "Other" and type a custom path
- **Q3 — Save** (header "Save"): "Where to save preferences?"
- "User (Recommended)" — `~/.baoyu-skills/` (all projects)
- "Project" — `.baoyu-skills/` (this project only)
After answers, write EXTEND.md, confirm "Preferences saved to [path]", then continue.
Full template: [references/config/first-time-setup.md](references/config/first-time-setup.md).
### Supported Keys
| Key | Default | Values | Description |
|-----|---------|--------|-------------|
| `download_media` | `ask` | `ask` / `1` / `0` | `ask` = prompt each time, `1` = always, `0` = never |
| `default_output_dir` | empty | path or empty | Default output directory (empty = `./url-to-markdown/`) |
**EXTEND.md → CLI mapping**:
| EXTEND.md key | CLI argument | Notes |
|---------------|-------------|-------|
| `download_media: 1` | `--download-media` | Requires `--output` to be set |
| `default_output_dir: ./posts/` | Agent constructs `--output ./posts/{domain}/{slug}.md` | Agent generates path, not a direct flag |
**Value priority**: CLI arguments → EXTEND.md → skill defaults.
## Usage
```bash
# Default: headless capture, markdown to stdout
${READER} <url>
# Save to file
${READER} <url> --output article.md
# Save with media download
${READER} <url> --output article.md --download-media
# Wait for interaction (login/CAPTCHA) — auto-detect and continue
${READER} <url> --wait-for interaction --output article.md
# Wait for interaction — manual control (Enter to continue)
${READER} <url> --wait-for force --output article.md
# JSON output
${READER} <url> --format json --output article.json
# Force specific adapter
${READER} <url> --adapter youtube --output transcript.md
```
