URL to Markdown

Fetches any URL via Chrome CDP and converts HTML to clean 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

Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-url-to-markdown/EXTEND.md && echo "project"
test -f "$HOME/.baoyu-skills/baoyu-url-to-markdown/EXTEND.md" && echo "user"

# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-url-to-markdown/EXTEND.md) { "project" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-url-to-markdown/EXTEND.md") { "user" }

EXTEND.md Supports: Download media by default | Default output directory | Default capture mode | Timeout settings

First-Time Setup (BLOCKING)

CRITICAL: When EXTEND.md is not found, you MUST use AskUserQuestion to ask the user for their preferences before creating EXTEND.md. NEVER create EXTEND.md with defaults without asking. This is a BLOCKING operation — do NOT proceed with any conversion until setup is complete.

Use AskUserQuestion with ALL questions in ONE call:

Question 1 — header: "Media", question: "How to handle images and videos in pages?"

• "Ask each time (Recommended)" — After saving markdown, ask whether to download media
• "Always download" — Always download media to local imgs/ and videos/ directories
• "Never download" — Keep original remote URLs in markdown

Question 2 — header: "Output", question: "Default output directory?"

• "url-to-markdown (Recommended)" — Save to ./url-to-markdown/{domain}/{slug}.md
• (User may choose "Other" to type a custom path)

Question 3 — header: "Save", question: "Where to save preferences?"

• "User (Recommended)" — ~/.baoyu-skills/ (all projects)
• "Project" — .baoyu-skills/ (this project only)

After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

Supported Keys

EXTEND.md → CLI mapping:

Value priority:

1. CLI arguments (--download-media, -o, --output-dir)
2. EXTEND.md
3. Skill defaults

Features

• Chrome CDP for full JavaScript rendering
• Two capture modes: auto or wait-for-user
• Clean markdown output with metadata
• Handles login-required pages via wait mode
• Download images and videos to local directories

Usage

# Auto mode (default) - capture when page loads
${BUN_X} ${SKILL_DIR}/scripts/main.ts <url>

# Wait mode - wait for user signal before capture
${BUN_X} ${SKILL_DIR}/scripts/main.ts <url> --wait

# Save to specific file
${BUN_X} ${SKILL_DIR}/scripts/main.ts <url> -o output.md

# Save to a custom output directory (auto-generates filename)
${BUN_X} ${SKILL_DIR}/scripts/main.ts <url> --output-dir ./posts/

# Download images and videos to local directories
${BUN_X} ${SKILL_DIR}/scripts/main.ts <url> --download-media

Options

Capture Modes

Wait mode workflow:

1. Run with --wait → script outputs "Press Enter when ready"
2. Ask user to confirm page is ready
3. Send newline to stdin to trigger capture

Output Format

YAML front matter with url, title, description, author, published, captured_at fields, followed by converted markdown content.

Output Directory

Default: url-to-markdown/<domain>/<slug>.md With --output-dir ./posts/: ./posts/<domain>/<slug>.md

• <slug>: From page title or URL path (kebab-case, 2-6 words)
• Conflict resolution: Append timestamp <slug>-YYYYMMDD-HHMMSS.md

When --download-media is enabled:

• Images are saved to imgs/ next to the markdown file
• Videos are saved to videos/ next to the markdown file
• Markdown media links are rewritten to local relative paths

Media Download Workflow

Based on download_media setting in EXTEND.md:

Ask-Each-Time Flow

1. Run script without --download-media → markdown saved
2. Check saved markdown for remote media URLs (https:// in image/video links)
3. If no remote media found → done, no prompt needed
4. If remote media found → use AskUserQuestion:
   • header: "Media", question: "Download N images/videos to local files?"
   • "Yes" — Download to local directories
   • "No" — Keep remote URLs
5. If user confirms → run script again with --download-media (overwrites markdown with localized links)

Environment Variables

Troubleshooting: Chrome not found → set URL_CHROME_PATH. Timeout → increase --timeout. Complex pages → try --wait mode.

Extension Support

Custom configurations via EXTEND.md. See Preferences section for paths and supported options.
