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

No annotations are providedholpen, and the description discloses no behavioral traits, side effects, return value characteristics, or limitations. 'V1' only signals a version, not tool behavior.

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 extremely short, but it is under-specified rather than concise. With 4 parameters and no other documentation, three words are insufficient to support correct invocation.

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, no annotations, and no parameter documentation. The definition fails to provide even the basic information an agent needs to understand what the tool does, how to call it, or what to expect in response.

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 0% and all 4 parameters (query, country, language, maxTimeout) are undocumented. The description adds no meaning to any of them, leaving their formats, defaults, and purposes entirely unclear.

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 'V1 Google News' is a versioned label that simply restates the tool name. It contains no verb or action indicating what the tool does, such as fetching, searching, or listing news.

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 guidance on when to use this tool versus its siblings google_local and google_search. An agent cannot determine the appropriate context or selection criteria.

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