How One Developer Built a Lint-Proof AI Code Guard for 10 Production Repos
Your Claude.md file telling AI to 'never interpolate SQL' is just a suggestion. Here's how one developer turned good intentions into mechanical guarantees that actually catch mistakes.
⚡ Key Takeaways
- Documentation-based AI guidance ('always use safeParse') is non-deterministic—custom lint rules and ast-grep patterns enforce it mechanically. 𝕏
- Most AI-generated production bugs pass TypeScript and compile cleanly; they're structural antipatterns (N+1 queries, SQL injection) that require domain-specific linting. 𝕏
- This developer's three-layer approach (oxlint + ESLint + ast-grep) caught dozens of production-breaking issues that standard tooling missed entirely. 𝕏
