AI CODE REVIEW

Push your code.
Get a review that's actually right.

Cerberus reviews every pull request the moment you open it — full-repo context, not just the diff, and every finding double-checked before it reaches you. Less noise, fewer things to second-guess.

Pull Request #42 Review
BUG Potential null pointer at user.settings — add null check before access.
PERF N+1 query in loop at line 45 — consider batch fetching.
QUALITY Good use of early returns. Clean separation of concerns.
1 finding double-checked and dismissed as a false positive before you ever saw it.

Not just another noisy AI reviewer.

Most AI reviewers optimize for finding things. Cerberus optimizes for finding things that are actually true — every comment is double-checked before it reaches you, and it remembers what your team has already decided.

🔍

Self-verified findings

Every issue Cerberus raises gets a second, independent look before it's posted — a dedicated verification pass reads the same code and asks 'is this actually true?'. Findings that don't hold up get quietly dropped, not shown to you.

🧠

Learns your team's conventions

When your team replies "that's intentional" or "that's our convention" on a review comment, Cerberus remembers — and stops raising it on every future PR. The more you use it, the quieter it gets.

💬

Steerable, right from the PR thread

Reply /cerberus ignore, focus, or pause to redirect a review mid-PR — plus path-specific rules in .cerberusconfig and existing lint results all feed into what it flags.
