get_news_summary

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 only states the action ('Get a summary') but does not explain what happens with invalid URLs, whether content is fetched live, error behavior, or what constitutes a summary. This is minimal transparency.

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 that is front-loaded with the key information. Every word contributes meaning, and there is no redundancy or filler.

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 (one parameter, output schema exists), so the description is minimally adequate. However, it lacks usage context, behavioral notes, and any distinction from sibling tools beyond the URL scope, leaving gaps that could confuse an agent selecting between news tools.

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 the description only adds 'by URL' to clarify the article_url parameter. It does not explain format, constraints, or how the URL should be provided. The description adds minimal meaning beyond the schema's parameter name and type.

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 'Get a summary of a specific article by URL' – a specific verb and resource with a defining scope (by URL). This distinguishes it from sibling tools that fetch news lists or categories rather than a single article summary.

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 gives no explicit or implied guidance on when to use this tool versus alternatives. It does not mention that this is for retrieving a summary for a specific article URL, as opposed to browsing lists, nor does it mention any prerequisites or exclusions.

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