get_latest_news

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

With no annotations, the description carries the full burden for behavioral disclosure. It only says 'Get the latest news' with no details on sorting, time windows, or potential pagination. While not misleading, it fails to specify any behaviors beyond the basic retrieval intent.

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 concise sentence of six words, immediately stating the core action and subject. No filler or redundancy. For a tool with one parameter, this level of brevity is appropriate.

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 with an output schema covering return structure and a single parameter. However, the description omits any context about what constitutes 'latest', how the limit is applied, or any access constraints. Sufficient for basic use but lacking in depth for a fully informed agent.

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% for the single 'limit' parameter with a clear description. The tool description adds no further parameter explanation, so it does not surpass the schema's contribution. Baseline of 3 is appropriate.

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 a specific verb ('Get') and resource ('latest news from Tagesschau'). It is unambiguous and implicitly distinguishes from sibling tools like search_news or get_news_by_ressort, which serve different needs.

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 implies usage for retrieving current top news items, but does not explicitly state when to choose this over alternatives (e.g., search_news for queries, get_regional_news for locations). No exclusions or alternative references are provided.

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