v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It states it uses a public RSS feed, implying no auth, and returns fresh stories, but it does not mention any limits, side effects, or return format. It is not contradictory, but minimal.
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 sentences, direct and front-loaded. No unnecessary words. Efficient.
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 no-parameter news fetch, the description is adequate but could specify the return format or number of stories. It says 'stories' but not what a story contains. With no output schema, this is a gap.
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?
Zero parameters, schema coverage 100%. Baseline is 4 since no parameters need explanation. The description does not add parameter semantics but none are needed.
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: getting Daily Express top stories. It mentions the source (public News RSS feed) and that they are fresh. It is clear but does not explicitly differentiate from sibling tools like dailyexpress_headlines or dailyexpress_sections, though the term 'top stories' implies a specific subset.
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 explicit guidance on when to use this tool versus alternatives. There are many sibling news tools (e.g., dailyexpress_headlines, dailyexpress_article) but the description does not mention them or conditions for choosing this one. The only hint is 'top stories' which is not a clear selection criterion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
