Code review with AI + RAG: how to review intent, not just style

The best review isn't "change this to that". It's: does this meet the intent? does it break any edge? does it increase risk? Using AI with repo context (RAG) helps see architecture and patterns before commenting.

Why traditional review fails

Focus on style and formatting consumes time and lets intent, security and regression errors slip through. The reviewer doesn't always have product and decision context.

What contextual review is

Reviewer (human or AI with RAG) understands the problem the PR solves, the API contracts and the edges (nulls, permissions, performance). Only then suggests changes.

A better PR flow

1. Author writes "Intent" (3–6 lines): problem, decision, tradeoff. 2. AI does a sweep: risks, security hotspots, regressions. 3. Human reviews what matters: authorization, data, contracts and performance. Result: less nitpick, more quality.

Key takeaways

Contextual review saves time and improves quality. Intent + AI + human on critical decisions is a flow that scales.

FAQ

Is RAG required? No, but having the codebase as context greatly improves AI suggestions.

Who writes the Intent? The PR author. It takes a few minutes and guides the whole review.
