get_drive_file_download_url

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses that the file is prepared and available via HTTP URL for 1 hour, and explains export behavior for native files. It does not mention any destructive effects or auth requirements beyond the email parameter, which is acceptable for a read-like operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with a clear first sentence, followed by bullet points for export options. It is concise yet covers all necessary details without fluff. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity and the presence of an output schema (as per context signals), the description adequately explains the return value (str with download URL and metadata) and the 1-hour availability. It could mention what 'file metadata' includes, but it is acceptable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Despite 0% schema coverage, the description adds full parameter semantics: required fields user_google_email and file_id are explained, and export_format is described with explicit options and default behaviors (PDF for Docs/Slides, XLSX for Sheets). This compensates completely for the lack of schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Gets a download URL for a Google Drive file' with specific verb and resource. It distinguishes from siblings like get_drive_file_content by explaining it returns a URL, not the content. The details on export formats for different file types further clarify purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains when to use this tool (to get a download URL) and notes that the URL is valid for 1 hour. However, it does not explicitly compare to alternatives like get_drive_file_content or mention when not to use this tool. Still, the context is clear enough for an agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
