Update Drive file

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

No annotations exist, so the description must disclose side effects. It mentions 'replace its content' which implies destructive overwriting, but does not confirm whether the entire file is replaced, whether partial updates are possible, or what happens if only name is provided. No mention of permissions or reversibility.

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 a single concise sentence that gets directly to the point. It wastes no words, but its brevity leaves out important context addressed in other dimensions.

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 mutation tool with no annotations, output schema, or additional behavioral details, this description is insufficient. It does not specify return values, error conditions, whether content is overwritten, or the role of the account parameter. Despite the schema covering 80% of parameters, the tool's overall context is not fully described.

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?

The schema already provides descriptions for 4 of 5 parameters (80% coverage), so the description doesn't need to elaborate much. The description clarifies that 'name' relates to renaming and 'content' to replacing content, adding some meaning, but it does not clarify the 'account' or 'mimeType' roles, especially since mimeType lacks a schema description.

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's function: renaming a file and/or replacing its content. This is a specific verb+resource combination that distinguishes it from sibling tools like upload, delete, and share, though it does not explicitly contrast them.

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 guidance is provided on when to use this tool versus alternatives. It omits prerequisites, exclusions, or context such as whether it can be used for files not owned by the user or when to prefer upload over update.

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