What it does

When installed, this skill gives the AI agent the project context for the Repomix browser extension: a WXT and Manifest V3 codebase that works in Chrome, Firefox and Edge and adds a Repomix button to GitHub repository pages. The agent learns the folder layout, the npm commands for dev and build runs, how the 12 translation languages are organised, and cross-browser API caveats, so it can make changes without re-reading the whole project.

Great for

  • Contributors working on the Repomix browser extension in the browser/ directory
  • Developers adding a new language or updating translations
  • Maintainers handling Chrome versus Firefox compatibility issues

Skip it if

  • Developers building unrelated browser extensions, since the instructions are specific to this repository and its WXT setup
  • Anyone expecting a standalone tool: the skill is only guidance and adds no features of its own

Try asking

  • “Add a Firefox polyfill for the storage call in the background script”
  • “Add a new Japanese-style locale following the i18n instructions”
  • “Run the lint and test steps and fix anything that fails in the content script”
