v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden and does useful work: 'Returns fresh... from its public RSS feed' signals read-only behavior, no authentication, and a current snapshot. It doesn't mention count or return shape, but for a zero-parameter feed tool these are minor omissions.
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 one sentence, front-loaded with the core action and then adds source/freshness detail. There is minor redundancy between 'Get 9to5Mac top stories' and the restated 'top stories', but nothing that bloats it.
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 simple zero-argument RSS top-stories tool with no output schema, the description is largely complete: source, freshness, and return concept are all stated. The main gap is not addressing how it relates to ninetofivemac_headlines, but overall an agent can safely invoke 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?
There are zero parameters and the schema fully documents this (empty properties/required). Per the 0-parameter baseline, the description need not add parameter detail; nothing is missing.
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 names a specific action ('Get'), a resource ('9to5Mac top stories'), and a source ('public RSS feed'), so an agent understands the tool's core function. It does not explicitly differentiate this from the sibling ninetofivemac_headlines, so it misses the top tier for sibling distinction.
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 usage context is implied: use this when you need current/trending 9to5Mac Apple news stories. However, there is no explicit guidance about when to choose this over ninetofivemac_headlines, ninetofivemac_sections, ninetofivemac_article, or ninetofivemac_author.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
