This skill guides creation of JavaScript bookmarklets that are safe and ready for direct installation. It enforces critical constraints (block-style comments only, IIFE wrapper, javascript: protocol prefix), details a workflow for pretty-printing and minifying code, and provides installation options (draggable installer or Terser-generated links). The output is a copy-paste-ready bookmarklet plus usage and testing guidance.
Use when a user asks for small pieces of browser-run JS (bookmarklets), needs code that will run when clicked from the bookmarks bar, or asks for a draggable/installable utility link for webpages. Also useful when converting small DOM-manipulation or data-extraction snippets into production-ready bookmarklets.
Likely usable by assistant agents that can generate JavaScript snippets and format outputs for users (Chat-based coding assistants, Claude/GPT-style code assistants).
Instruction-only skill for generating browser bookmarklets with strict formatting rules (IIFE wrapper, block comments only, javascript: protocol). No scripts to execute — purely template/guidance. Well-organized with clear patterns for DOM manipulation, clipboard ops, and dynamic loading. References an external installer at austegard.com and a GitHub repo for bookmarklet storage.
No security concerns. Pure instruction skill with no executable scripts. External URL reference is a minor reliability risk but not a security one.
