file_manager

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

No annotations are provided, so the description must carry the full burden. It only mentions 'upload' and 'send to server' but does not disclose side effects, authentication requirements (e.g., login needed), file size limits, or whether uploaded files overwrite existing ones. Lack of behavioral detail.

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 sentences, minimal waste. However, the second sentence ('Drop files here to send them to the server') reads more like a UI placeholder than a tool description. It could be more direct and structured. Decent but not excellent.

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?

Given no output schema and simple structure, the description should explain the tool's role in the file management workflow. It does not mention that upload is only one part of file management, nor does it reference sibling tools like list_files for retrieval. Leaves gaps for an agent.

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 has no parameters (coverage 100%, baseline 3), but the description fails to clarify how files are provided. The phrase 'drop files here' suggests a UI interaction, but for an API it is ambiguous. No explanation of expected input format (e.g., multipart upload), file types, or size limits. Underwhelming for a file upload tool.

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 states 'Upload and manage files', which clearly identifies the tool's purpose. However, 'manage' is somewhat vague, and the sibling tool 'list_files' suggests file listing is separate, so upload is distinct. Score 4 for specific verb+resource but lacking full precision.

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 on when to use this tool versus alternatives like list_files or check_model_integrity. The description does not provide any context for appropriate usage or mention prerequisites or exclusions.

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