Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (0 parameters, no output schema, no annotations), the description is minimally viable. It tells the agent what the tool does but does not clarify the nature of the returned help (e.g., text, JSON, command reference) or the scope of 'using After Effects effects'. For a help tool, some additional context about output would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
