Tools

Open-source tools I build, mostly around making AI coding agents behave the way a senior engineer would.

Everything here is Apache 2.0 and runs locally. No SaaS, no login, no remote telemetry.

fscars — bolt-on correction primitive for AI coding agents

pip install fscars

Turn a correction you keep repeating to Claude Code into a deterministic hook that fires the next time the same situation comes back. The framework comes from my paper Lucy Syndrome in LLM Agents; the package is the clean reference implementation.

Currently Claude Code only — Codex CLI adapter on the roadmap, adapter API public for community contributions.

lucy-syndrome — research framework + production case

The companion repository to the paper. Includes the framework templates, 11 scars + 9 hooks from a real civil-engineering operation, the Phase 2 logging primitive, and the Phase 3 opportunity observer.

It is not a package — you read it, you adapt the templates, and you wire your own hooks. Use fscars if you want a one-line install instead.

More tools land here as they stabilize. If something is documented in a blog post but not yet here, it is still in alpha and not ready for outside adoption.
