AI First-Pass Code Review

Paste a diff or code block and get a senior-engineer-style first pass before it reaches a human reviewer. - Flags bugs, security risks, performance issues, and maintainability problems - Rates each finding Critical, High, Medium, or Low with line references and a fix - Add project conventions (e.g. "no nested ifs") for sharper, more relevant results - Run it on every PR so reviewers only spend time on what's left after the obvious stuff is caught

Prompt
Review this code as a senior developer:

{{code_or_diff}}

Check for:
1. Bugs: Logic errors, off-by-one, null handling, race conditions
2. Security: Injection risks, auth issues, data exposure
3. Performance: N+1 queries, unnecessary loops, memory leaks
4. Maintainability: Naming, complexity, duplication
5. Edge cases: What inputs would break this?

For each issue:
- Severity: Critical / High / Medium / Low
- Line number or section
- What's wrong
- How to fix it

Be harsh. I'd rather fix issues now than in production.

Balanced Senior Engineer PR Review

Give it the PR's stated goal and your repo's architecture and conventions to get a review that avoids both rubber-stamping and nitpicking. It checks correctness, readability, maintainability, test coverage, and backward compatibility in one pass, then sorts findings into Confirmed Issues, Possible Risks, and Nice-to-Haves, closing with three ready-to-paste GitHub review comments.

Constructive Review Comment Writer

Describe the issue you've spotted in plain English along with the specific lines and fuller details, and get back a ready-to-paste GitHub review comment instead of staring at a blank comment box. The output is specific, explains why the issue matters, includes a concrete suggested fix, and skips filler openers like "Great work, but..." — also useful as a template for junior reviewers learning to write good comments.

Correctness-Only Bug Review

Paste a diff to get a review that stays narrowly focused on logic errors, null dereferences, race conditions, and off-by-one bugs — the kind that actually reach production — while ignoring formatting and naming entirely. Each bug found comes with the exact line, why it's a bug, and a suggested fix, and it says so explicitly if nothing turns up rather than padding the review with style notes.
