🔬MOSS Agent Rewrites Its Own Code, Doubles Task Score
TL;DR
A new paper introduces MOSS, a system that lets autonomous agents evolve by rewriting their own source code, not just prompts or memory. On a four-task benchmark it lifted the mean grader score from 0.25 to 0.61 in one cycle with no human help.

Key Points
Source-level self-rewriting reaches routing and dispatch the prompt layer cannot touch
Mean grader score rose from 0.25 to 0.61 in a single cycle with no human intervention
Tested on the OpenClaw agent platform across four tasks
Authors argue source edits are Turing-complete and resist long-context drift
Why It Matters
If agents can safely patch their own harness, the line between deployed software and a self-improving system starts to blur for production teams.
