Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Search'), identifies a clear resource ('RoxyAPI knowledge base'), and states the output ('ranked documentation snippets, each with a source URL'). It also enumerates the content areas covered (API endpoints, SDKs, WordPress plugin, auth, UI components, integration guides), so an agent knows exactly what this tool searches though.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
