Anthropic Leaks 4-Agent Setup That Cuts Codebase Audit from 3 Days to 20 Minutes

Anthropic has leaked a 4-agent setup that reduces codebase audits from 3 days to 20 minutes. The approach maps the repo by blast radius rather than folder, allowing four auditors to work in parallel on separate contexts (deps, secrets, dead code, hot paths) without seeing each other's findings. Ranking is done by code, not an agent, sorting by production impact and dropping duplicates. The fixer only opens patches for the top slice, and verification runs the test suite on each patch, sending failures back to the fixer. The loop closes by feeding results back into the map.
