meta-context-watcher

Invoke the context-watcher skill to write a handover.md file capturing in-flight work, uncommitted changes, decisions, and the exact next action. It then instructs you to type /clear so the next session starts fresh with full context.

handover.md describes one moment and is overwritten wholesale each session, while OPEN-WORK.md is a standing backlog edited line by line. The handover holds current task state; the backlog holds everything unfinished that outlives the session.

A Stop hook measures real token usage from the transcript's last recorded usage and fires when context crosses min(context_handover_pct of the window, context_handover_cap). The window is detected from the model family, falling back to a declared or 200k window.

User-requested items always outrank found items, deferred user items sit below live user items but above found ones, and larger size breaks ties within the same origin. Ranks use tens (10, 20, 30) so insertions avoid renumbering.

Any edit made after the handover is work the handover does not describe, so the next session inherits a file that is already wrong about the state it reports. The handover must be the last action, followed only by the /clear instruction.

Yes, set context_window explicitly via the meta-memory-settings skill if the watcher reports measuring more context than the window. Otherwise detection follows model family first, then the launcher's declared window, then a 200k fallback.
