MOSS: Self-Evolution through Source-Level Rewriting in Autonomous Agent Systems
Teaching AI agents to fix their own code when they fail users
Autonomous AI agents today remain frozen after launch—they repeat the same mistakes until humans manually rewrite their code. MOSS lets agents automatically rewrite their own source code in response to real failures, not just adjust prompts or skill files. In one test, the system doubled task performance from 0.25 to 0.61 without human intervention.
AI agents deployed in production currently stay broken until developers push an update. MOSS eliminates that waiting period by letting agents self-repair in real time, which means faster fixes to critical failures and reduced downtime. Since the system modifies actual code rather than just prompts or configuration files, it can fix structural problems that no amount of text tweaking could reach.
