pcg_skeleton_generate · Loenn MCP: Risk & Policy

WHAT IT DOES

What pcg_skeleton_generate does on Loenn

AI agents invoke pcg_skeleton_generate to trigger actions in Loenn. 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 pcg_skeleton_generate needs a policy

The name suggests procedural content generation (PCG), which likely executes a generation algorithm to create or modify map content. Given the server's context of editing .bin map files and sibling tools that add rooms/entities, this tool likely generates map skeletons (Write/Execute level). With an empty description, confidence is lowered.

From the tool's definition Tool name 'pcg_skeleton_generate' and server description mentions 'procedurally generate' Celeste .bin map files; description is empty and uninformative.
