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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered by structured data. The description adds nothing on top of that: no mention of what the detection returns, whether results are region-scoped legal records, latency/cost characteristics, or how the returned matches should be interpreted.

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?

It is a single sentence fragment with no padding, but that brevity comes from under-specification rather than economy — the whole text is a restatement of the title, so there is no useful information to be front-loaded. Nothing in it earns a place beyond naming the tool again.

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?

This is a 4-parameter, 2-required-parameter detection API with no output schema, so the description must explain what a detection result contains and how to interpret it. It does none of that, leaving the agent unable to predict the response shape or judge whether a hit is actionable.

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%: limit, regions, productText and productTitle all carry their own descriptions including the region code list and character limits. The description contributes no additional parameter meaning, which is the baseline-3 case when the schema does the work, but it also does not mislead about inputs.

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 restates the title verbatim ('IP Risk Detection RG: text Trademark Detection API') without a verb, an object of the detection, or any explanation of what the call actually does with the product title. It only gestures at the domain (text-based trademark checking), which the name and title already convey. It also does not distinguish it from close siblings such as nexscope_text_trademark_detector or nexscope_data_rg_trademark_graphic_detection.

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?

There is no when-to-use guidance, no prerequisites, and no steering toward or away from any alternative tool. The agent must infer from the name alone that this is for checking product titles/text for trademark conflicts, and cannot tell from the text why it would pick this over the other trademark or graphic-detection siblings.

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