v1.17.7Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral burden. It indicates this is a read-only retrieval ('Get', 'Returns current stories') and specifies the source feed, but omits details like update frequency, result count, pagination, or output format. For a simple no-parameter fetch this is minimally adequate but not rich.
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?
Two concise sentences, front-loaded with the core action and resource, then a clarifying note on the data source. No wasted words.
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?
Given the tool has no parameters and no output schema, the description sufficiently states what is returned (current stories from a dedicated listing). It could add a bit more about volume or structure, but for a simple news-fetch tool it is nearly 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?
The tool takes zero parameters, and the schema is empty. Per calibration, a zero-parameter tool receives a baseline of 4. The description does not need to explain any parameters, and it adds no conflicting information.
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 states a specific verb ('Get') and resource ('Medical News Today latest health news') and explains the source is the site's dedicated Health News listing. However, it does not explicitly differentiate from close siblings like medicalnewstoday_headlines or medicalnewstoday_sections, leaving potential overlap unaddressed.
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 provided on when to use this tool versus alternatives (e.g., medicalnewstoday_headlines, medicalnewstoday_article). The implied use case is fetching the latest health news, but no conditions or exclusions are stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
