v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It states the operation is a read ('Get') and that the data is 'public' and 'editorial', which gives some context. However, it doesn't disclose potential pagination, output format, or any other behavioral traits. Acceptable for a simple zero-param tool.
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 short sentences with zero waste. The first sentence states the action, the second adds the important context of its relationship to dailystaruk-headlines. Perfectly front-loaded.
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-param tool with no output schema, the description is nearly complete. It tells what it returns and its purpose. It could mention the return type or any limitations, but nothing critical is missing given the simplicity.
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, and the schema has no propertiesate. The baseline for 0 parameters is 4, and the description doesn't need to explain parameters it doesn't have.
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 clearly states the verb 'Get' and the resource 'Daily Star (UK) sections', and further clarifies it returns the 'editorial section inventory' used by dailystaruk-headlines. This distinguishes it from other section tools for different outlets.
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?
It implicitly tells when to use this tool: when you need the Daily Star (UK) section inventory, especially the one used by dailystaruk-headlines. It doesn't explicitly mention alternatives or exclusions, but the context of sibling tools makes the selection clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
