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

No annotations are provided, so the description carries full burden. It states that files are stored under a given name and can be removed via doc_delete_upload, which gives some behavioral info. However, it does not mention potential side effects like overwriting an existing name, authentication requirements, or rate limits. It is average but not exhaustive.

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 detailed but not excessively verbose. It repeats the url explanation (once in the description and once in the schema), which adds a little redundancy, but overall it is well-structured and conveys necessary info efficiently.

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 the tool's simplicity and no output schema, the description covers what happens after upload (stored under name, removable) and the lifetime (kept for token). It lacks explicit mention of error cases or return values, but for this scope it is sufficiently complete.

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 100%: all three parameters (url, name, docx_base64) have meaningful descriptions. The description also clarifies the 'name' parameter's format and purpose. This fully explains how to use each parameter without ambiguity.

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 uploads a .docx file to the endpoint for later use, distinguishing it from sibling tools like doc_delete_upload and doc_read. It explicitly says 'Send an existing Word document to this hosted endpoint', which is a specific verb and resource.

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?

It explains when to use it (to get a document ready for other tools) and provides guidance on choosing between base64 and url, including a recommendation for large files. It also mentions that uploads are kept for the token, implying a session context. No explicit comparison to alternatives, but the context is clear enough.

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