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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It does not state that the operation is read-only, what the response format is, or how the 'refresh' parameter affects caching. The description adds no behavioral detail beyond what the schema already provides (e.g., 'Bypass the news cache').

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, front-loaded sentence that states the core function efficiently. It is not bloated, but it may be too terse to convey all necessary usage context. Still, it earns a high score for conciseness.

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?

With no output schema and no annotations, the description leaves significant gaps: it does not explain what 'per-region' means or how to specify a region, what the response looks like, or when to set 'refresh'. The tool's full behavior is underspecified for an agent to use it confidently.

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%, so the baseline is 3. The description's phrase 'arbitrary place name' aligns with the 'place' parameter but adds no extra constraints or format details. The 'refresh' parameter is only documented in the schema; the description does not clarify when it is useful.

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 states the tool returns safety news, with a distinction between per-region and arbitrary place queries. It names the resource ('safety news items') and the two usage modes. However, it does not explicitly differentiate from sibling tools like get_incidents or get_trends, though 'news' is conceptually distinct.

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 is given on when to use this tool versus alternatives. The description implies usage for news, but there are no explicit exclusions or conditions. Sibling tools like get_incidents or get_crime_year are not referenced, so an agent must infer which tool fits a given request.

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