Instrument

Nothing about your crew, agents, tasks, or tools changes. instrument() subscribes to CrewAI’s module-level event bus.

Check it arrived

Run it once, then open Observe → Sessions and select your environment. Your run appears as a reconstructed trace. If nothing arrives, confirm the machine is connected with failproofai config --status.
