Session cut

Skill brenbuilds1/cutweight/skills/session-cut

Session-weight hygiene. Use when sessions run long, when an agent gets slower or starts forgetting mid-session, when deciding between /clear, /compact, or a fresh session, or when every message feels heavier than the work in it. Calls the moment a session has blown the weight limit: cut it right and start the next one light.From its SKILL.md

Session Cut

Every message you send re-sends the conversation so far. The longer the session, the heavier each message gets, and the older context starts working against you. Knowing when to cut a session saves more tokens than any single trim.

The Calls

  • One task, one session. Starting an unrelated task in an old session makes the new task carry the old one's weight.
  • /clear between unrelated tasks. It is the cheapest reset there is.
  • /compact only to continue the SAME task past context limits. Compaction is a summary; treat it as lossy, because it is.
  • Fresh session with a handoff note beats a compacted haze. Before you clear, have the agent write five lines: what was done, what is next, which files matter. Paste that into the new session.

The Tells

Cut the session when:

  • The agent re-reads files it already read this session.
  • It forgets or contradicts a decision made earlier in the session.
  • Replies slow down or drift off the task you actually asked for.
  • The work left is unrelated to the transcript behind it.

Hard Rules

  • Never /compact as a reflex. Ask first: is this the same task?
  • The handoff note gets written before the clear, not remembered after.
  • If the agent is fighting the context instead of the problem, cut the session. Reset.
