Bookmarklet Creation

What it does

This skill provides a structured workflow and standards for creating browser-executable JavaScript bookmarklets. It enforces critical constraints (IIFE wrapper, use of /* */ block comments, and the javascript: protocol), describes preparation steps (pretty-printed source, minification), and lists deliverables and testing guidance so code is usable directly from the browser/bookmarks bar.

When to use it

Use when a user asks for a small browser utility, a drag-to-bookmarks installer, or a snippet that should run directly from the bookmarks bar. Also useful when generating bookmarklet install links, preparing code for Terser-based minification, or ensuring cross-browser clipboard and DOM handling.

What's included

• Scripts: none bundled in repo (has_scripts=false) but clear examples and code patterns are provided in the skill body.
• References: none listed, but installer integration and CDN usage described.
• Instructions: step-by-step rules for comment style, IIFE wrapping, protocol prefixing, error handling, console logging, clipboard operations, dynamic library loading, and testing checklist.

Compatible agents

Good for agents that generate or format JavaScript snippets and produce installation links (any code-capable assistant: Copilot/Codex/GPT-based code assistants, Claude Code).
