Zero-documentation code review

Ship reviews when there are no docs to review against.

CodeGuard reads the code itself. Paste a diff or connect a pull request — no PRD, no spec, no paperwork required. Its combined MAP → GUARD → VERIFY engine flags what matters and skips the noise.

3-stage
MAP → GUARD → VERIFY

One engine, three stages

The combined cascade routes only the risky changes to the expensive checks — that is where the token savings come from.

MAP

Clusters every changed file and assigns learned directory and collision rules to locate risk.

GUARD

A crossover gate decides which files are worth deep review — batching the small, isolating the large.

VERIFY

Deep LLM verification runs only on what GUARD fires, returning precise, actionable findings.

On the roadmap

Turning missing docs into living ones

Living Spec

Reverse-engineer goals, rules and expected states from the diff, for the reviewer to validate.

Structural intent

Parse the changed files to deduce types, signatures and logic boundaries directly from the code.

Boundary checks

Surface unhandled edge cases — empty states, limits, timeouts, permission gates — proactively.

Approved learning

Every reviewer correction can become a repository rule — only after a human approves it.

Review your next change in seconds

No documentation? That is the whole point. Paste a diff and let CodeGuard do the reading.
