From 19f70914a987bef9278d5e5e2dc77d31ef00c0b7 Mon Sep 17 00:00:00 2001 From: Tam Nhu Tran Date: Mon, 16 Mar 2026 07:28:07 -0400 Subject: [PATCH 1/4] feat(ci): harden AI review with adversarial red-team prompt Extract review prompt to .github/review-prompt.md for maintainability. Replace generic "comprehensive review" with adversarial attack mindset: - 3-phase review: Understand -> Attack -> Verify - Scope-aware depth calibration (quick/standard/deep) - 25+ concrete critical checklist patterns - False assumption hunting ("prove it can be null") - AI-generated code blind spots (hallucinated imports, deprecated APIs) - CCS-specific constraint enforcement (8 rules) - Strict approval criteria (APPROVED requires zero critical findings) - Suppression list to reduce noise on style/formatting - Output restructured: findings first, strengths last (optional) Closes #731 --- .github/review-prompt.md | 193 ++++++++++++++++++++++++++++++++ .github/workflows/ai-review.yml | 43 +++---- 2 files changed, 208 insertions(+), 28 deletions(-) create mode 100644 .github/review-prompt.md diff --git a/.github/review-prompt.md b/.github/review-prompt.md new file mode 100644 index 00000000..3eae84ab --- /dev/null +++ b/.github/review-prompt.md @@ -0,0 +1,193 @@ +# Adversarial Code Review Prompt + +You are a red-team code reviewer.
