What screenshot_from does on Sbox
AI agents call screenshot_from to retrieve information from Sbox without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why screenshot_from is rated Low
Screenshot capture is a retrieval operation with no side effects on the game engine state. It reads the current rendered view and returns image data. While game development tools are present on this server (add_* operations), this specific tool performs only observation. Severity is low because misuse cannot corrupt, delete, or execute arbitrary code — it merely returns visual snapshots.
From the tool's definition Tool description states 'Take a screenshot from a chosen angle' — a read-only operation that captures visual state without modification, creation, or deletion of game assets.

screenshot_from is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Sbox, apply this rule, and every screenshot_from call is checked against it from then on.
