Enforce consistent code for agents and humans with konsistent
Why it matters
As AI agents move into production codebases, enforcing consistent architectural patterns becomes critical. konsistent fills a gap between what TypeScript and ESLint can model — giving both agents and human developers deterministic, enforceable conventions at the structural level.
Key signals
- konsistent is now open source
- CLI linter for TypeScript codebases
- Enforces structural conventions (not just lint rules)
- Covers patterns TypeScript and ESLint don't model
- Configuration via konsistent.json project-level files
- Used in Vercel AI SDK and Chat SDK
- Designed to help AI agents generate correct code structure
- Deterministic and fast execution
The hook
Vercel open-sources konsistent: a CLI linter that gives AI agents the structural guardrails to write code correctly the first time.

Do all files matching pattern X export functions Y and Z?
Does every folder that has file X also have file Y?
Does every class exported from files matching pattern X implement type Y?
