v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral load, and it does disclose the return contents in useful detail: about 10 items, and per-item title, canonical URL, summary, publish time, joined author names and lead image. It assumes a read-only 'Get' but says nothing about freshness, pagination, or rate limits. Since no output schema exists, the field enumeration is genuinely additive.
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?
Three tight sentences, front-loaded with the verb and resource. Every sentence earns its place: the first states the action, the second the volume, the third the return shape. No 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 zero-parameter read tool with no output schema, the description supplies the return fields an agent needs and the approximate item count. The one omission is the lack of differentiation from gamerant_headlines, which matters for correct selection among siblings.
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 no parameters, and the description explicitly says so ('Takes no parameters'), matching the empty input schema. With zero parameters the baseline is 4.
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 verb and resource ('Get Game Rant top stories') and describes the content shape. However it does not distinguish itself from the close sibling gamerant_headlines, and the 'top stories' framing versus 'latest stories' in the next sentence is slightly ambiguous about whether it is ranked or chronological.
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?
There is no when-to-use or when-not-to-use guidance. With siblings like gamerant_headlines and gamerant_article available, the description gives the agent nothing to decide between them, leaving routing entirely to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
