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

No annotations beyond basic hints; description mentions size limits (<=25MB images, <=200MB videos) which is useful, but does not disclose what happens on failure, whether it's a mutation of existing creations, or if there are any side effects. The bare 'convert' and 'finalize' imply mutation, but no detail on success/error behavior or partial failures.

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 brief and front-loaded with the critical 'Step 2 after PUT' context, then adds size limits. It could be more structured, but it's efficient for a simple tool.

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?

Tool has no output schema and few annotations, so description must carry more weight. It covers size constraints but leaves out parameter usage, error handling, and any post-conditions. For a finalization step, more detail on what 'convert' implies (e.g., does it delete temp files? does it return creation IDs?) is needed.

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 2 params with 0% description coverage; description does not explain the difference between 'path' and 'uploads' or how they relate. Agents cannot infer which parameter to use for what, especially given no required params and nested objects.

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 it finalizes uploads after a previous request_upload step, converting temp paths to creations. It could be more explicit about the verb 'finalize' and the resource, but it does distinguish from sibling `request_upload`.

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?

Description explicitly indicates this is 'Step 2 after PUT from creations_request_upload', providing clear sequencing context. It doesn't mention when not to use it, but the step-specific guidance is helpful.

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