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

With no annotations, the description carries the full burden of behavioral disclosure. It clearly indicates what the tool returns and the market scope, but it does not mention potential limitations, data freshness, whether it is advisory only, or behavior for unsupported markets. 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 compact and front-loaded: the core action and deliverables appear first, followed by parameter guidance. Every sentence adds useful information with no filler or redundancy.

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?

Given the tool has an output schema, only two simple parameters, and no required fields, the description covers the essential invocation context. It could be more complete with examples of product_category values or explicit validation rules for market, but nothing critical is missing.

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%, so the description meaningfully compensates by explaining market as a jurisdiction selector with allowed values and product_category as an optional input for Nice class suggestion. For two simple parameters, this provides solid semantic grounding beyond the bare 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?

Description states a specific verb ('Return') and resource ('per-jurisdiction trademark filing guidance') with concrete deliverable components: process, fee range, timeline, Nice classification. This makes its purpose distinct from sibling tools like brand_conflict_screen and ip_risk_assessment, even without naming 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?

The description implies usage context: cross-border sellers seeking jurisdiction-specific trademark filing guidance, with market restricted to US/EU/UK/CN/JP. However, it does not explicitly state when to choose this tool over its siblings or mention any exclusions, leaving some inference required.

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