What Memory Hygiene does

Memory Hygiene periodically re-verifies environment-dependent claims in persistent memory and knowledge notes. It stamps last_verified and confidence, and proposes archiving entries that have drifted or gone obsolete.

Memory Hygiene is cataloged under Automation on DirSkills. Memory Hygiene comes from a repository tagged agent-loop, agent-plugins, agent-skills, agentic and ai-agents.

README

Excerpt

COG Memory Hygiene Skill

Purpose

Prevent the stale-but-confident failure mode: a memory or knowledge note that was correct when written ("the webhook lives at X", "the board ID is Y") silently drifts after the environment changes, yet still ranks high at recall and gets acted on.

The system move (adapted from "From Model Scaling to System Scaling: Scaling the Harness in Agentic AI", Gu, UC Berkeley, arXiv:2605.26112): make trust a runtime decision, not a property of the stored item. Re-verify against the live environment, and keep per-entry last_verified and confidence as first-class fields so future recalls can weigh trust.
