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

Annotations declare readOnlyHint=true and idempotentHint=true, which are consistent. The description adds behavioral context: the command returns a JSON with a 'code', and the workflow avoids loading large files into context. No contradictions.

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?

Description is concise yet informative, with a clear flow: states purpose, recommends usage, lists steps, and explains benefit. 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?

Covers the main workflow and return value (curl command with code), but lacks details on error handling, input validation, authentication needs, or the exact format of the curl command. Given the absence of an output schema, more completeness would be helpful.

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 coverage is 0% (no parameter descriptions in schema). The description only references 'file_path' implicitly, ignoring 'account' and 'file_name'. It does not clarify their purpose or format, failing to compensate for the lack of schema documentation.

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?

Description clearly states the tool returns a curl command for uploading files, specifies the resource (upload command) and action (returns). It distinguishes from siblings like webdiet_upload_anexo by outlining the two-step process.

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?

Explicitly recommends for large files and provides a step-by-step flow. However, it lacks explicit guidance on when not to use this tool (e.g., for small files one could possibly upload directly).

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