Get Drive File Download URL

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

Beyond annotations (readOnly, idempotent, non-destructive), the description discloses key behaviors: saving to local disk, temporary URL validity in HTTP mode, and format conversion rules for Google native files. This exceeds what annotations provide and sets clear expectations for side effects and return values.

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 main statement, mode-specific details, and a bulleted list for format conversions. Every sentence serves a purpose without redundancy, making it concise yet informative.

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?

The description fully covers the tool's behavior across modes, file types, and export formats. It explains return values (local path vs URL) and edge cases like native file conversion, making it complete for an agent to select and invoke the tool correctly without needing additional context.

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?

Schema coverage is 100%, but the description adds value by explaining export format mappings per file type (e.g., Docs to PDF/DOCX, Sheets to XLSX/PDF/CSV). This enriches the parameter semantics beyond the schema's plain option list.

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 it downloads a Google Drive file and saves it to local disk, using a specific verb and resource. It distinguishes from siblings like get_drive_file_content or get_drive_shareable_link by focusing on the download behavior and local file access.

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 provides clear usage context, explaining mode-specific behavior (stdio vs HTTP) and export format options. It does not explicitly name alternatives or exclusions, but the context makes it obvious when to use this tool for downloading files rather than just reading or sharing them.

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