Create File

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

The description discloses that the tool can fetch content from a URL (fileUrl), which aligns with openWorldHint=true annotation. It also mentions shared drive support. No contradictions with annotations. Could mention that file creation may fail if insufficient 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 two sentences, concise and front-loaded with the core purpose. Every sentence adds value without redundancy.

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 a tool with 7 parameters and an output schema, the description covers the essential behavior and key options. It does not explain the return value, but the output schema likely does. Slightly more context on authentication or file size limits could improve completeness.

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 86%, so parameters are well-documented in the schema. The description adds value by grouping input methods (content vs fileUrl) but does not provide additional semantics beyond the schema.

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 tool creates files in Google Drive, supporting shared drives. It distinguishes from siblings like create_drive_folder or import_to_google_doc by specifying it accepts direct content or a fileUrl.

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 does not explicitly state when to use this tool versus alternatives like import_to_google_doc or update_drive_file. It implies usage for creating files with content or URL, but lacks conditions or exclusions.

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