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

Annotations already declare readOnlyHint, idempotentHint, and closed-world, so the safety profile is covered. The description contributes one genuinely useful behavioral fact — the USPTO serial number and attorney note only exist once the filing is actually filed, so responses are state-dependent — but says nothing about failure modes for bad tokens or unfiled records.

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?

A single short clause with no padding, but it is a sentence fragment with no verb and no leading statement of the operation. Conciseness is fine; front-loading clarity is not.

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?

Annotations supply the safety profile, the schema fully documents both parameters, and with no output schema the description usefully enumerates the returned fields. For a two-parameter read tool, that is sufficient 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 coverage is 100% and both parameters are documented there, including where the secret token comes from. The description adds no parameter-level meaning beyond the schema, which is the expected baseline here.

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 is a noun phrase listing what is returned (status, attorney note, USPTO serial number) rather than a verb stating the operation, so the agent must infer 'retrieve' from the name. It adds concrete content that distinguishes it from list/search siblings, but it never differentiates from the close sibling get_application, which reads like the same subject at a different stage.

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 statement of when to use this versus get_application, get_order, or get_filing_type, which all appear to operate on the same filing/application domain. The implicit prerequisite (having the secret token) is only discoverable from the schema, not the description.

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