WHAT IT DOES

What memvid_sketch does on Memvid

AI agents invoke memvid_sketch to trigger actions in Memvid. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why memvid_sketch needs a policy

memvid_sketch triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

memvid_sketch Rate-limited
