Pattern: Self-Improving Agents That Write Their Own Skills Are Going Mainstream

Hermes Agent·medium signal

The 'agent that grows with you' framing is now a shipping category, not a research demo: NousResearch's Hermes Agent writes its own reusable skills from experience and self-updates, while zhayujie/CowAgent markets itself as a super-assistant that 'self-evolves with memory and knowledge.' The common loop is persistent memory plus the ability to author new skills, so the agent's capability set expands run-over-run without human authoring. This validates the self-improving outer-loop pattern that advanced builders have been running in private harnesses.
