Get Trademark Documents

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

readOnlyHint=true already establishes this as a safe read, and the description adds that results come as 'document bundles' covering amendment/refusal/decision packages. It does not disclose return format (files, links, PDFs), pagination, or size, which matters for a document-fetch tool.

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 front-loaded sentence with no filler. Minor ambiguity from 'such as', which suggests the listed kinds are examples while the schema enum is exhaustive.

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?

Two required params and no output schema mean the definition should clarify what a 'bundle' actually returns; that is absent. The core input contract is clear, but an agent cannot anticipate the response shape.

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%, so the schema already documents both applicationNumber (10-digit JP format) and the documentKind enum. The description merely restates the enum values in prose and adds no format or constraint detail beyond the schema.

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?

States a specific verb ('Fetch') and resource ('trademark application document bundles') and enumerates the document categories available. It is distinguishable from the sibling get_patent_documents and get_design_documents by the trademark resource, though it never explicitly contrasts them.

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 guidance on when to use this versus the other trademark siblings (get_trademark_progress, get_trademark_registration), nor any prerequisites such as needing a valid application number first. Usage is only implied by the tool name.

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