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 adds 'fresh' and 'public' which are useful context, but does not mention response structure, error handling, or rate limits. It provides minimal behavioral transparency beyond the basics.
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 sentences with no wasted words. The main purpose is front-loaded, and the additional context is succinct. It earns high marks for efficiency.
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 single-parameter tool with no output schema, the description is adequate but does not describe the return format (e.g., list of headline objects, ordering, or count). An agent would not know the response shape without further exploration. It is functional but could be more complete.
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?
Schema coverage is 100% with a clear enum and description for the section parameter. The description adds only that it is a 'public' section, which is minor and not essential. It does not compensate for any gaps, but none exist.
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 states a specific verb+resource ('Get DW section headlines') and clarifies it returns headlines from one public section. It clearly differentiates from other DW tools like dw_news or dw_article by focusing on section-scoped headlines. Not a tautology and unambiguous.
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 usage for a specific section but does not explicitly mention when to choose this over sibling tools like dw_sections or dw_news. It lacks any 'use this instead of...' guidance, leaving selection to inference from the parameter and name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
