Userscript Development

Guide for writing Tampermonkey/Violentmonkey userscripts.

Workflow

Phase 1: Requirements

Ask one at a time:

1. Target site - URL pattern (e.g., https://example.com/*)
2. Goal - CSS styling, add feature, remove element, keyboard shortcut, etc.
3. Output location - Where to save the .user.js file

Phase 2: DOM Inspection

Option A: Fetch URL directly (try first for public sites)

• Use WebFetch to retrieve page HTML
• Search for relevant selectors, CSS variables, data attributes
• Works for public sites not behind login
