# Context Hygiene Rule trigger: context bloat, stale observations, resolved content inlined, noisy exploration. avoid: context rot and lost-in-the-middle failures. ``` replace(resolved_content): path_ref_only; delegate(noisy_exploration): subagent; prune(stale > 3_turns) on_context_growth: summarize(old_observations); keep(decisions+outcomes); discard(superseded_content) ``` This skill is advisory: the client reading it has no mechanism to enforce it, and this policy stays advisory even when compiled by `chock` -- it ships rule text, not a blocking hook.
