emu

Reconstructs session working state from the last saved checkpoint and remember.md. Use immediately after compaction when context is lost. Auto-triggers when: files being edited are unknown, project instructions are unclear, or user says "what happened" / "what were we doing".

Use when Emu fires a Drift Alert. Explains what drift means and how to break out. Auto-triggers on: "drift alert", "going in circles", "stuck", "keeps reading same file", "test won't pass".

Auto-loads when context usage feels high or compaction is approaching. Teaches token-efficient behavior. Triggers on: "context is low", "running out of space", slow responses, or after 30+ turns in a session.

Reduces output token usage by injecting terse-mode instructions. Removes filler phrases, trailing summaries, and converts prose to bullets. Configurable: off / lite / full / ultra. Auto-triggers at session start or when context is running low.

Reference when user asks why output was truncated or how to bypass compression. Also use before every bash command compression decision.
