works_file_upload

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

With no annotations, the description must carry the burden of behavioral disclosure, but it only reveals a 2-step metadata+PUT flow. It does not mention needed permissions, overwrite behavior, partial-failure handling, or the response format.

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, front-loaded sentence with no redundancy. The parenthetical '2-step metadata+PUT flow' efficiently adds useful behavioral context without wasting words.

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 upload tool with no annotations, no output schema, and 0% schema description coverage, one sentence is insufficient. Missing are prerequisites, error conditions, permission requirements, and any information about return values or success/failure indicators.

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 the description partially maps 'local file' to file_path and 'My Drive folder' to parent_folder_id. However, the name and user parameters are left undocumented, and the description does not fully compensate for the low schema coverage.

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 uses a specific verb 'Upload' with a clear resource 'a local file into a My Drive folder', distinguishing it from siblings like works_file_download. The phrase '2-step metadata+PUT flow' adds technical specificity without ambiguity.

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, nor on prerequisites such as target folder existence or file accessibility. The only context is the action itself; there are no exclusions or alternative recommendations.

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