WHY IT NEEDS A POLICY

Why set_animation_param needs a policy

The tool modifies animation parameters in a Godot project. This is a Write operation: it changes configuration state reversibly without executing arbitrary code or deleting data.

From the tool's definition Tool name is 'set_animation_param' and description states 'Set animation parameter.' The verb 'set' indicates modification of animation parameters, which are configuration data within the Godot engine.

set_animation_param Rate-limited

set_animation_param stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
