Create Drive File

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

Annotations already convey that this is a mutating, non-idempotent, non-destructive operation, so the description only needs to add context beyond that. It does add useful behavior about shared drives and accepted content sources, but it omits potential side effects such as server-side URL fetching from fileUrl or required authorization state.

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?

Two tightly written sentences with no filler. The primary action and resource are front-loaded, followed by the two most decision-relevant behaviors: shared drive support and accepted content input formats.

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?

For an 8-parameter tool, the schema carries most of the parameter details and output schema is present, so the description need not enumerate every field. It covers the core operation, shared drive capability, and content input modes. A minor gap is that it does not state whether content inputs are mutually exclusive or how conflicts are handled, but the schema's descriptions largely compensate.

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 100%, so the schema already documents all eight parameters. The description's mention of 'direct text content, inline base64 bytes, or a fileUrl' summarizes the schema's content, base64_content, and fileUrl parameters without adding new parameter-level meaning beyond what the schema provides.

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 the action ('Creates a new file in Google Drive') and the specific resource, while adding meaningful scope details: shared drive support and three content source modes. This distinguishes it from related tools like create_drive_folder and update_drive_file without needing to inspect the schema.

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?

No explicit guidance is given about when to use this tool versus alternatives such as import_to_google_doc, import_to_google_sheets, copy_drive_file, or create_drive_folder. The agent must infer selection from the tool name and the first verb rather than from any stated conditions or exclusions.

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