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

No annotations are provided, and the description does not disclose any behavioral traits such as side effects, authorization needs, rate limits, or what 'passes certification' implies operationally. The description is nearly silent on behavior beyond the basic action.

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 very short but includes extraneous metadata (category, cost, endpoint). It is concise but not well-structured for agent decision-making. The truncation indicates incompleteness.

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 presence of an output schema, the return values might be documented elsewhere, but the description fails to provide enough context about input expectations or what the tool does in enough detail for an agent to use it confidently. The description is too sparse for a tool with one complex parameter.

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?

The input schema has 0% description coverage and only a generic 'params' string. The description mentions a 'query' parameter but is truncated and does not explain how to structure the JSON string or what other parameters might be available. This leaves the agent with minimal guidance.

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 states it is a 'Third-party search that passes certification', so the basic purpose is clear, but it lacks specificity about what exactly is being searched (e.g., web, documents, APIs). The sibling tools do not directly overlap in naming, but the vagueness reduces clarity.

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 tool versus alternatives. There is no mention of use cases, prerequisites, or what differentiates it from other search-like tools among the siblings. The description only provides metadata (cost, category) without functional guidance.

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