# Context Hygiene

context-hygiene · version 0.0.3

Advisory — Advisory only. It is skill text, and nothing stops a violation. Chock adds friction. It is not a security boundary. 

In a git repo: advisory (The agent reads the text, and nothing stops a violation.)



## What it does

Trigger: context bloat, stale observations, resolved content inlined, noisy exploration. avoid: context rot and lost-in-the-middle failures.
