get_drive_file_download_url

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

The description discloses important behaviors: files are prepared and available for 1 hour, and native files are exported to specific formats. It doesn't mention auth requirements or rate limits, but with no annotations, it carries some burden. The 1-hour expiry is a useful behavioral trait, but missing details like whether the tool triggers a copy or affects permissions.

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 bullet points for export formats and clear Args/Returns sections. Every sentence adds information; no redundancy or filler.

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 (3 params, output schema present), the description fully explains purpose, parameters, return value, and the 1-hour validity. It doesn't explicitly state the return format but that's covered by the output schema. Minor gap: no note on error cases or permission requirements.

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 description coverage is 0% and parameters have no enums, so the description must compensate. It explains each parameter: user_google_email (required, user's email), file_id (Drive file ID), and export_format (optional with explicit options and defaults). It adds meaning beyond the bare schema types.

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' and explains the behavior for Google native files vs. other files, distinguishing it from sibling tools like get_drive_file_content or get_drive_shareable_link. It also details export format mappings, making the purpose unambiguous.

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 implies when to use this tool (when a URL is needed, including export conversions) but does not explicitly say when not to use it or mention alternatives. However, the detailed export format behavior provides clear context for when to choose this over sibling tools like get_drive_file_content.

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