update

# /update — Quick Checkpoint Save progress mid-session without closing. Fast and low-ceremony: a log line plus a state touch only if something actually changed. **Invocation:** user-only (`disable-model-invocation: true`) — checkpoints are timed by you, and the flag keeps this skill out of ambient context. ## Configuration Read the optional `workspace.yaml` at the project root. Below, `<state_dir>` and `<sessions_dir>` are its resolved values; defaults are `state/` and `sessions/`. Full reference: `docs/state-model.md`. ## Instructions 1. **Scan recent conversation.** Identify in ~30 seconds: what was worked on, any decisions made, any state changes needed. 2. **Append to session log.** Add to `<sessions_dir>/{TODAY}.md` (create it if absent): ```markdown ## Update: {TIME} - {what was worked on, 1–3 bullets max} ``` 3. **Update state only if something changed.** Touch `<state_dir>/current.md` only if a priority shifted, a thread opened or closed, or a task completed. Skip otherwise — an `/update` with no real change writes only the log line. 4. **Confirm.** One line: "Checkpointed: {brief description}". ## Design principles - **Fast.** A checkpoint should cost seconds, not minutes. - **Skip what's clean.** Don't rewrite `current.md` for a checkpoint that changed nothing. - **Standing rule.** Whenever you run `/update`, log first, then decide whether state actually moved — don't invent a state change to justify the run.
