Claude + Cursor Production-Grade Code Review System Prompt Library

Stop rewriting sloppy AI code reviews. Start shipping clean PRs with a reliable senior reviewer on every commit.

You ask Claude or Cursor for a review and get vague, over‑eager refactors, missed regressions, and security blind spots. You waste time coaxing better answers, rewriting comments, and hand‑tuning prompts just to get something usable. It slows your team and bloats every PR cycle.

This library gives you a complete, production‑grade system‑prompt setup built specifically for multi‑file, real‑world pull requests. You get 12 hardened configuration files and review modes that turn Claude or Cursor into a consistent senior engineer who catches regressions, flags security risks, respects existing architecture, and writes comments your team actually wants.

What’s Included:
- Core Review System Prompt: Enforces senior‑level reasoning, strict diff‑only review, and noise reduction.
- Regression Sentinel Module: Targets async pitfalls, state drift, boundary conditions, and failure‑path changes.
- Security Review Pack: Detects secret leakage, unsafe refactors, and risky dependency diffs.
- Multi‑File Context Manager: Guides models through large PRs without losing track of call chains.
- Comment‑Style Enforcer: Matches your team’s tone, format, and severity levels.
- Refactor Guard Rails: Blocks unnecessary rewrites and keeps reviews focused on correctness.
- Race‑Condition Detector: Production‑tested patterns for concurrency‑prone services.
- Frontend/Backend Specialized Variants: Tailored prompts for React, Node, Python, Go, and TypeScript repos.
- Fast‑Pass Mode: A lightweight version for sub‑20‑line diffs.
- Deep‑Audit Mode: A strict pass for high‑risk code and release branches.
- Integration Notes for Claude & Cursor: Drop‑in instructions for each tool.
- Team Setup Guide: How to standardize reviews across all engineers.

Built from patterns used on hundreds of production PRs across SaaS teams handling async services, distributed systems, and regulated‑data workflows. These prompts were refined through real failures—race conditions, flaky states, leaking secrets—not theory.

Who This Is For:
- Teams dealing with noisy or inconsistent AI PR reviews.
- Senior engineers who want faster reviews without losing depth.
- Leads standardizing review quality across mixed‑experience teams.

Who This Is NOT For:
- Hobby projects with trivial diffs.
- Teams expecting auto‑refactors instead of correctness‑focused reviews.
