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

Annotations already mark this as read-only and non-destructive, and the description adds useful beyond-schema context by stating the URL is minted on demand and never persisted. It does not mention expiration or subsequent upload steps, but for a simple URL-generation tool this is reasonably transparent.

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 short sentences with no filler. The key fact—what is returned—is front-loaded, and the persistence behavior is stated in a single additional clause.

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?

The tool is simple, has an output schema, and safety is covered by annotations. However, the description omits contentType semantics, does not explain the applicationId wrapper, and only names two of the four allowed kind values, leaving moderate ambiguity for correct invocation.

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 only 33%, and the description does not compensate. It loosely ties the tool to specimen/logo uploads but does not explain applicationId, contentType, or the additional kind enum values like POWER_OF_ATTORNEY and OTHER.

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 returns a presigned S3 PUT URL for a specimen or logo, which is specific and action-oriented. It is distinguishable by resource type from generic upload tools, though it does not explicitly name sibling alternatives.

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 when-to-use guidance or alternatives are mentioned. It does not explain how the returned URL fits into the larger upload workflow, such as whether the caller should then PUT to S3 and subsequently call trademark_attach_document.

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