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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the agent knows this is a safe, external-data-backed read. The description adds that the tool performs risk analysis over user-supplied text, but says nothing about what the risk output contains, latency, quotas, or coverage of the regional jurisdictions listed in the schema.

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 opening sentence is well front-loaded, but it is followed by a long comma-separated keyword list that repeats terms verbatim ('brand infringement screening', 'listing compliance', 'intellectual property risk' each appear twice). That bloat dilutes an otherwise clean statement of purpose.

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?

There is no output schema, so the description should hint at what a detection run yields (matched marks, risk level, per-region results); it only implies 'infringement risk analysis'. Combined with the complete input schema and read-only annotations, this is adequate but leaves a real gap for interpreting results.

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 100%, with every parameter (productTitle, productText, regions, limit) documented in-schema including limits and supported region codes. The description adds no parameter-level meaning beyond that, which is acceptable given the schema already carries the burden, so the baseline 3 applies.

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 first sentence names a specific verb+resource: trademark detection and infringement risk analysis on e-commerce product listings, with the scope (titles, descriptions, bullet points) clarified later. It does not, however, differentiate itself from close siblings such as nexscope_data_rg_text_trademark_detection or the trademark graphic detector, so an agent cannot fully rule out an overlap.

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 gives a clear trigger context ('Trigger when users mention...' plus the explicit fallback 'Even if the user does not explicitly say trademark, trigger this skill whenever their need involves checking whether product text contains potentially infringing trademarks'). This is strong positive guidance, but there are no when-not conditions and no named alternatives among the many sibling trademark/copyright/patent tools.

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