How do I install this agent skill?

- Gen Agent Trust Hubpass
This skill allows an AI agent to fetch web pages using a headless browser and convert them into Markdown files. It handles JavaScript-rendered content via Chrome CDP and can download images and videos to local directories. The primary security considerations involve the execution of a local browser process and the ingestion of untrusted web content from arbitrary URLs, which could theoretically contain instructions designed to influence the AI agent's behavior (indirect prompt injection). The skill implements user confirmation prompts for initial setup and media downloads.

What does this agent skill do?
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:
- Determine this SKILL.md file's directory path as
SKILL_DIR - Script path =
${SKILL_DIR}/scripts/<script-name>.ts - Replace all
${SKILL_DIR}in this document with the actual path
Script Reference:
| Script | Purpose |
|---|---|
scripts/main.ts | CLI entry point for URL fetching |
Preferences (EXTEND.md)
Use Bash to check EXTEND.md existence (priority order):
# Check project-level first
test -f .tuzi-skills/tuzi-url-to-markdown/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.tuzi-skills/tuzi-url-to-markdown/EXTEND.md" && echo "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)" — ~/.tuzi-skills/ (all projects)
- "Project" — .tuzi-skills/ (this project only)
After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

Supported Keys
| Key | Default | Values | Description |
|---|---|---|---|
download_media | ask | ask / 1 / 0 | ask = prompt each time, 1 = always download, 0 = never |
default_output_dir | empty | path or empty | Default output directory (empty = ./url-to-markdown/) |
Value priority:
- CLI arguments (
--download-media,-o) - EXTEND.md
- 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
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
# Download images and videos to local directories
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> --download-media
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) |
--download-media | Download image/video assets to local imgs/ and videos/, and rewrite markdown links to local relative paths |
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:
- Run with
--wait→ script outputs "Press Enter when ready" - Ask user to confirm page is ready
- 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
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:
| Setting | Behavior |
|---|---|
1 (always) | Run script with --download-media flag |
0 (never) | Run script without --download-media flag |
ask (default) | Follow the ask-each-time flow below |
Ask-Each-Time Flow
- Run script without
--download-media→ markdown saved - Check saved markdown for remote media URLs (
https://in image/video links) - If no remote media found → done, no prompt needed
- 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
- If user confirms → run script again with
--download-media(overwrites markdown with localized links)
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.
