WHAT IT DOES

What refresh_device_catalog does on Uefn

AI agents invoke refresh_device_catalog to trigger actions in Uefn. 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.

RISK

Why refresh_device_catalog is rated High

This tool triggers an active operation (force rescan and rebuild) within the UEFN editor environment. It doesn't merely read data—it initiates a rescan and reconstruction process, making it an Execute-category action. Misuse could cause disruption to the editor state or catalog integrity, but is not directly destructive or financial.

RECOMMENDED RULE

The rule that runs refresh_device_catalog safely

refresh_device_catalog Rate-limited

refresh_device_catalog stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
