Prompt

Holds a prompt once when the prompt cache has gone cold and shows the estimated re-write cost; /keepwarm pings the cache.

Hands a long session over to a fresh one before context runs out: watches the context fill, offers to write HANDOFF.md from the session's own transcript, and loads it into the next session.

Turns your corrections into saved rules: spots a stated preference in your prompt and offers to save it to CLAUDE.md from a band above the prompt.

/replay steps through every file edit Claude made in the last turn, one colored diff at a time.

Live panel and progress band for subagents: model, context fill, tokens, estimated cost and time. Toggle with /agents-info.

A second agent on the side reads what Claude just did and flags anything you might miss, as a note above the prompt. Toggle with /should-know.
