v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It states the tool returns a 'live-verified' section inventory, which conveys that the data is up-to-date and validated. It also connects the output to the headlines endpoint, providing context about the data's purpose. It does not mention auth, rate limits, or pagination, but for a zero-parameter read-only listing this is adequate.
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 compact sentences with no wasted words. The core action is front-loaded ('Get The Daily Caller sections'), followed by a concise clarification of what the tool returns and its relationship to the headlines endpoint.
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 a simple purpose, the description is complete. It tells the agent what the tool does, what it returns, and how the result relates to another endpoint. There are no missing details that an agent would need to call it 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?
There are no parameters, so the description has no parameter semantics to explain. The baseline for zero parameters is 4, and the description appropriately focuses on the output rather than input details.
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 uses a specific verb ('Get') and resource ('The Daily Caller sections'), clearly identifying the tool's purpose. It also notes the sections are 'used by the headlines endpoint', which distinguishes this tool from other section-listing tools for different publications.
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 implies this tool should be used to retrieve the section inventory for The Daily Caller, especially before using the headlines endpoint. However, it does not explicitly state when to choose this over alternatives like dailycaller_headlines or dailycaller_news, nor does it provide any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
