v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses the data source (public top-stories RSS feed), the freshness of content, and the exact fields returned. It could mention pagination or result count limits, but for a simple read-only listing this is reasonably 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?
Two concise sentences with the core purpose front-loaded. The first sentence states exactly what the tool does, and the second adds useful output details without redundant 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?
For a tool with no parameters and no output schema, the description provides everything an agent needs: the source, the freshness, and the returned fields. No critical information is missing for invoking the tool correctly.
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 input schema has zero parameters, so the description has no parameter semantics to explain. The zero-parameter baseline of 4 applies, and the description appropriately focuses on what the tool returns rather than inputs.
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?
States a specific action ('Get') and resource ('GMA News top stories'), making the tool's function immediately clear. It differentiates itself from sibling tools like gmanews_article or gmanews_headlines by narrowing to the top-stories RSS feed, so an agent can tell them apart.
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 clearly indicates this tool is for retrieving fresh GMA News top stories, which gives a clear usage context. It does not explicitly name alternatives or exclusion conditions, but the top-stories framing is specific enough for most selection scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
