v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must carry the behavioral load. It adds context that the taxonomy is 'public' (implying no authentication) and that it is accepted by the headlines endpoint. However, it does not describe the return format (e.g., array of strings, objects), potential pagination, or any error behavior. For a simple read operation this is acceptable but not fully transparent.
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 two concise sentences that front-load the action and then provide a brief clarification of the output. Every word adds value—'Get' is direct, 'public' and 'accepted by the headlines endpoint' provide useful context without fluff.
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?
For a parameterless, read-only listing tool without an output schema, the description is quite complete. It states what is returned and its purpose. It could mention the exact shape of the returned taxonomy (e.g., array of section names) to remove any guesswork, but the current description is adequate for an agent to know how to use it.
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 has zero parameters, and the schema is an empty object. The description correctly omits parameter details. Per the guidelines, a zero-parameter tool gets a baseline of 4, and there is no missing parameter information to compensate for.
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 verb 'Get' and the resource 'PCMag sections', and elaborates that it returns the public product/topic taxonomy. It distinguishes itself from sibling tools like pcmag_headlines or pcmag_article by specifying it provides taxonomy used by the headlines endpoint, leaving no ambiguity about its function.
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 implicitly communicates when to use it: to obtain valid section values for the headlines endpoint. It doesn't explicitly contrast with alternatives, but since no other PCMag tool provides sections, the use case is clear. It would benefit from an explicit statement like 'Use this before calling pcmag_headlines to get valid section parameters.'
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
