Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no annotations, no output schema, and a single parameter, the description is quite minimal. It does not explain when to use this tool, what the test payload entails, or what the agent should expect after invocation. For a tool that triggers an external webhook, this lacks essential context for an agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
