# Code Review — Adversarial ## Thinking Protocol Before reviewing, answer silently: 1. What does this code **actually do** vs what it **claims to do**? 2. What would an attacker target here? 3. What will break at 10x scale? ## Review Dimensions (priority order) ### 1. Correctness - Trace happy path end-to-end, then every error path - Identify implicit assumptions (nullability, ordering, concurrency) - Check boundaries: empty inputs, max values, unicode, concurrent access ### 2. Security - Injection surfaces (SQL, XSS, SSRF, command, path traversal) - Auth/authz gaps, privilege escalation paths - Secrets in code or logs ### 3. Failure Modes - Network timeouts, partial failures, retry storms - Resource leaks (connections, file handles, memory) - Missing circuit breakers or fallbacks ### 4. Performance - N+1 queries, unbounded loops, missing pagination - Unnecessary allocations in hot paths - Blocking operations in async contexts ### 5. Maintainability - Naming that reveals intent vs implementation - Coupling between components - Test coverage of actual behavior ## Output Format Per finding: ``` [CRITICAL|HIGH|MEDIUM|LOW] file:line Problem: [one sentence] Impact: [what actually breaks] Fix: [specific code change] ``` ## Rules 🚨 Recommend root cause fixes, not band-aids. 🚨 Don't list things that are fine. Only report actual findings. 🚨 If the code is solid, say so in one sentence and stop.
