create_file_upload_request

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

With no annotations, the description must carry the full burden of behavioral disclosure. It only states that a request is created and a URL is returned, but it does not mention any prerequisites, side effects, or details about the upload request or URL lifetime.

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 sentence, but it is under-specified rather than concise. It omits critical information needed to use the tool, so the brevity is not an asset.

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?

The tool requires a nested object parameter with no schema description, and the description offers no guidance on its structure or the resulting upload URL's usage. Even with an output schema present, the lack of parameter context makes the description far below the minimum viable level.

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's only parameter, upload_request, is an opaque object with no field descriptions. The tool description provides zero additional information about how to construct the upload request or what fields are expected, leaving the parameter completely unexplained.

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 verb (Create), resource (file upload request), and outcome (get an upload URL). It distinguishes from the sibling create_file_download_request by clearly indicating the upload direction, though it does not explicitly name alternatives.

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 given on when to use this tool versus alternatives such as create_file_download_request. The usage is only implied by the tool's name and the one-line description, providing no context or exclusions.

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