AI Coding Agent Catches and Fixes Its Own Broken Code in Sandbox
Common_Dream9420 · reddit · 2026-08-13
A developer demonstrated an AI coding agent's ability to self-correct without human intervention. Given a vague prompt, the agent audited a service, identified 22 bugs ranked by blast radius, and wrote a fix.
During sandbox verification, the agent realized its own SQL injection fix failed the proof. It then diagnosed the issue, stripped the over-engineering, and re-proved it successfully. This sandbox mechanism simulates complex edge cases (like duplicate webhooks) to ensure code is rigorously verified before merging, moving beyond mere vibes.
