Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .baoyu-skills/baoyu-url-to-markdown/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-url-to-markdown/EXTEND.md" && echo "user"

EXTEND.md Supports: Default output directory | Default capture mode | Timeout settings

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

Usage

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

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

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

Options

| Option | Description | |--------|-------------| | <url> | URL to fetch | | -o <path> | Output file path (default: auto-generated) | | --wait | Wait for user signal before capturing | | --timeout <ms> | Page load timeout (default: 30000) |

Capture Modes

| Mode | Behavior | Use When | |------|----------|----------| | Auto (default) | Capture on network idle | Public pages, static content | | Wait (--wait) | User signals when ready | Login-required, lazy loading, paywalls |

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

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

Environment Variables

| Variable | Description | |----------|-------------| | URL_CHROME_PATH | Custom Chrome executable path | | URL_DATA_DIR | Custom data directory | | URL_CHROME_PROFILE_DIR | Custom Chrome profile directory |

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.
