IMPLEMENTATION TIPS

  1. 1

    Send only the diff, not the entire file: prefix with enough surrounding context (10–20 lines) to understand intent, but avoid bloating the prompt with unchanged code that adds cost without value.

  2. 2

    Define a severity taxonomy in your system prompt (Critical/High/Medium/Low) and instruct the model to output only Critical and High findings — this prevents alert fatigue from trivial style comments.

  3. 3

    Chain the review with a second pass asking the model to suggest specific code fixes for every Critical issue it found — inline suggestions close the loop from finding to resolution.
