Claudia is a plugin for Claude Code that acts as a proactive mentor — catching security issues, suggesting best practices, and teaching as you code. I built it end-to-end as both a product and a proof of what’s possible with AI developer tooling.

What I built

  • 10 skills, 15 hooks — From secret detection to CSS accessibility checks, each hook is a standalone quality gate
  • Proactive mentorship — Claudia doesn’t wait to be asked. She teaches during your workflow, not after.
  • Full test suite — 234+ pytest tests, CI on GitHub Actions across Python 3.9 and 3.12
  • Website — askclaudia.dev with docs, quickstart, and changelog

Result

Live on npm as claudia-mentor. Open source, actively maintained, and a demonstration of building AI-augmented developer tools from scratch.
