agentsop-session-state-hygiene

Decision protocol for managing the context/session state of an AI coding tool: when to /clear, when to keep context, and how to detect "context bleed" — the failure mode where stale conversation history biases the model against the current task. Surfaces a discipline that Aider (/clear), Claude Code (/clear), CrewAI (memory=False, re-instantiate), and LangGraph (new thread_id, subgraph isolation) all encode separately but none name as a skill.

# Session-State Hygiene · SOP

> One line: **context is signal; stale context is noise; clearing restores
> signal.** A coding session is a sliding window of evidence. Early in a task
> the window is pure signal. The longer it runs, the more dead ends, abandoned
> plans, and superseded files accumulate — and at some point yesterday's good
> context becomes today's bad bias. This skill is the discipline of noticing
> that moment and acting on it with the smallest correct cut.

> Source posture: every framework-specific claim is cited inline as
> `[tool/topic]`. Resolve tags against `references/R1-source-evidence.md` (full
> URLs) and `references/R2-tool-commands.md` (copy-pastable commands).
