Nous Research's Hermes Agent Adds Curator Feature to Auto-Retire Unused Skills After 30 Days

According to Nous Research, the Hermes Agent framework added a Curator feature on April 29 to manage the skill lifecycle automatically. The feature addresses a prior limitation where AI agents could accumulate skills indefinitely, bloating system prompts without removing unused ones.

Curator operates in two steps: a deterministic state machine tracks usage frequency and last invocation time, marking skills as stale after 30 days of inactivity and archiving them after 90 days; a secondary model then reviews remaining skills every 7 days during agent idle time to merge overlapping functions and update outdated content, running up to 8 iterations in a separate prompt cache. The feature only manages agent-created skills, preserves built-in and marketplace-installed skills, and supports user-locked skills via pin command. Curator is enabled by default and can be disabled. The PR comprises 2,200 lines of code with all 56 tests passing; it has been merged into main but not yet released in an official version.
