Guardrails for AI code
enforced at commit time.
A pre-commit validator that catches what review misses.
AI generates code fast — Sentinel makes sure it is correct. It runs as a Git pre-commit hook, validating staged files against architecture, security and quality rules, and blocks the commit on hard violations.
The problem Sentinel solves
AI assistants happily write code that violates your layering, hardcodes a secret, or introduces a timing attack. By the time a human reviewer notices, it is already in a pull request. Sentinel moves enforcement to commit time, where it is cheapest to fix.
What Sentinel does
Pre-commit enforcement
A Git hook validates every staged file and exits non-zero on hard violations — the bad commit never lands.
10 built-in rules
Five hexagonal-architecture rules, three naming rules, a hardcoded-secret check and a missing-test rule — covering the most common AI mistakes.
Three enforcement profiles
minimal (security only), standard (security + critical architecture) and strict (everything) — pick the level that fits your team.
Custom team rules
Add your own regex-based rules so Sentinel enforces the conventions specific to your codebase.
