PR Shield (Pull Request Risk Reviewer)

Mission

Build a SaaS product called “PR Shield” (Pull Request Risk Reviewer). 🎯 Goal An AI tool that analyzes GitHub pull requests and predicts: whether the PR is safe to merge what might break in production what areas of the codebase are affected potential bugs or regressions It acts like a senior reviewer that never sleeps. 🧩 Input User provides: GitHub pull request diff (code changes) or raw git diff text optional context: repo type / stack 🧠 Core Analysis Requirements The system must: Analyze code diffs line-by-line Identify risky changes such as: logic modifications API changes dependency updates security-sensitive edits removed validations or checks Infer system impact across modules Detect potential regression risks Evaluate test coverage gaps (if visible) Must: Avoid hallucinating missing context Clearly label assumptions Focus on engineering accuracy over verbosity 📊 Output Format (STRICT) Return a structured markdown report: 1. PR Summary What changed in simple terms High-level intent (if inferable) 2. Risk Score 0–100 overall risk Classification: Low / Medium / High / Critical 3. Risk Breakdown Logic risks API risks Data risks Security risks Dependency risks 4. Potential Breaking Changes What might break in production Which systems/components affected 5. Edge Cases Introduced New failure scenarios introduced by changes 6. Missing Safeguards Missing validation, tests, or checks 7. Suggested Fixes / Improvements Concrete engineering recommendations 8. Merge Recommendation Approve / Approve with caution / Request changes ⚙️ Behavioral Rules Be precise and engineering-focused Do not assume unseen code behavior Clearly distinguish: observed diff facts inferred risks Prioritize production safety analysis 🧪 UX Requirements Simple UI: paste PR diff OR GitHub PR link input Button: “Analyze PR” Output: structured review report Optional: GitHub comment-ready format ⚡ Performance Requirements Stateless processing (no DB required for MVP) Response time under 10 seconds Must handle large diffs efficiently 💼 Product Positioning This is an AI senior code reviewer for pull requests that: reduces human review fatigue catches risky changes before merge improves code quality and release safety 🏁 Success Criteria Produces realistic engineering review comments Detects risky diffs accurately Useful enough to be pasted directly into GitHub PRs Works without setup or integrations (copy/paste MVP) 💰 Monetization (optional guidance) Free: 10 PR analyses/month Pro: €15–25/month unlimited reviews Team: €59/month GitHub integration + shared insights 🔥 Key Differentiation Position as: “A senior engineer reviewing every PR before you merge it.” or “Catch production bugs before they ship.”
