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

Annotations are sparse (only openWorldHint and destructiveHint), so the description carries more burden. It does add behavioral context: it stores a snapshot report (persistence side effect) and performs external searches (USPTO, web), implying network calls and potential latency. However, it does not disclose whether the operation is synchronous, whether it modifies application state, or any rate limits or costs. Given minimal annotation coverage, this is adequate but not rich.

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, information-dense sentence with no redundant wording. It front-loads the primary action and lists the key components (USA search, phonetic variants, open web screening, snapshot storage). Every part adds value.

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 tool with two parameters (one required), an output schema, and a multi-step process, the description provides only a high-level overview. It does not explain the meaning of skipCommonLaw, prerequisites (e.g., application existence), or what the snapshot report contains. Since an output schema exists, the return type is partially covered, but crucial invocation details are missing, making it minimally viable.

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 50%: only applicationId has a description ('UUID value wrapper'), which is minimal, and skipCommonLaw has no description. The tool description does not reference or clarify any parameters, so it does not compensate for the gaps. It adds no meaning beyond the schema, and the coverage is not high enough to rely on schema alone. A score of 2 reflects the lack of parameter explanation.

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's function with a specific action verb ('searches'), the target resources (USPTO, open web), and the resulting artifact (snapshot report). It distinguishes itself from sibling tools like trademark_get_clearance_report by emphasizing the act of running a new clearance search versus retrieving an existing report.

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?

The description implies when to use it (when a clearance search is needed) but does not explicitly mention when not to use it or name alternatives like trademark_get_clearance_report. It gives clear context but omits exclusions. Since the tool name and description are self-explanatory, it earns a 4.

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