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

Annotations already declare this is a non-read-only, non-destructive, closed-world operation. The description adds useful behavior—scoped and single-use—but omits key details such as link expiration, permission requirements, whether the browser link is public, and what happens after upload completes.

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 front-loaded sentence with no filler. However, it is under-specified for a five-parameter mutation tool, so its conciseness comes at the cost of necessary context.

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?

For a link-generation tool with five parameters, no output schema, and zero schema descriptions, the definition is too sparse. It leaves the agent without parameter meaning, workflow guidance, or important behavioral details like link lifetime and access scope.

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 0%, and the description does not explain any of the five parameters. Required fields like workspace, file_name, mime_type, and size_bytes are left entirely to the schema, and the purpose enum is not addressed at all.

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 a specific verb and output: create scoped single-use upload and browser links. It distinguishes this from direct asset operations like assets_import or assets_list by emphasizing link creation, though it does not name a sibling explicitly.

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?

There is no guidance on when to use this tool versus alternatives such as assets_import or assets_get. The description implies the use case of obtaining an upload link but does not specify prerequisites, exclusions, or the workflow context.

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