Adversarial Iteration

Category: Dev Tools  ·  Sub-category: linters-formatters  ·  Last updated:
type:review
Use when iterating on a fix after an adversarial code review (Codex, human reviewer) surfaces design-level findings — not typos, lint, or formatter work. Frames the review/fix loop as implement -> [review -> REFLECT -> reproducer -> fix -> verify -> handoff] where each round runs in a fresh agent to prevent context accumulation. Provides a four-item cheap-checks list (timeline draw, upstream contract read, full lifecycle trace, variant enumeration) that catches recurring failure classes. No git commits during the loop — all changes commit together after zero-finding termination. Trigger when a review pass surfaces 2+ findings on a single change, when sibling bugs of an "already-fixed" issue keep appearing across rounds, or when the user asks "why did I miss this?". Do NOT use for single-line fixes where the cause is obvious from the diff, or for initial implementation work (use CLAUDE.md rules).

Work with adversarial review feedback instead of patching symptoms.
