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

With no annotations provided, the description carries the full burden of behavioral disclosure. It doesn't state that the tool is read-only, describe the output format, or mention any pagination or rate limits. The topic list is informational but not behavioral; it fails to explain what happens when the tool is called (e.g., returns article summaries or URLs).

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 sentence, front-loaded with the core purpose, followed by a compact topic list. Every word contributes to understanding; there is no filler or redundant detail, making it exceptionally concise and well-structured for a simple news tool.

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?

The tool is simple and the schema documents all parameters, but the description lacks information about the output format and doesn't provide usage context relative to siblings. It covers purpose and topics adequately but leaves the return value and positioning among similar tools unclear, making it minimally complete.

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 coverage is 100%, so the baseline is 3. The description adds meaningful value by listing 'liability' and 'auto' as valid topics, which are absent from the schema's topic enumeration. This expands the semantic understanding of the 'topic' parameter beyond what the schema provides, though other parameters (lang, limit) are not elaborated further.

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 identifies the tool as providing 'Insurance industry news by topic' and enumerates the supported topics, which conveys the resource and scope. However, it lacks an explicit verb like 'retrieve' or 'list', and it doesn't explicitly differentiate from sibling tools such as claim_news, though the broad topic list implies wider coverage.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention, for instance, that claim_news should be used for claims-specific news, nor does it state any exclusions or preferred contexts. The only usage hint is the list of topics, which implicitly suggests coverage but offers no comparative direction.

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