This plugin brings performance analysis, test coverage review and AI-driven code quality assessment into your agent. It runs on Claude, Codex and Cursor.

It ships as a set of parts you invoke as slash commands. Installation goes through the wshobson/agents marketplace. Author is Seth Hobson, MIT license.

  • find performance bottlenecks in code
  • see which parts lack test coverage
  • get an AI quality assessment of code
  • produce a performance report before release

Example prompts for the agent
