techradar_headlines

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only says 'Returns fresh TechRadar headlines from one public section hub page,' which implies a read-only operation but does not state auth requirements, rate limits, return format, or whether pagination is involved. This is minimal coverage for a tool with no annotation safety profile.

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 redundant wording. It is front-loaded with the action and resource, and the additional clause about 'fresh' and 'public' adds a little context without bloat. It is concise and easy to parse.

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 one-parameter tool with an enum, the description is moderately complete. It does not explain what 'headlines' entails (e.g., list format, metadata), does not reference the techradar_sections tool for obtaining valid slugs, and does not mention any response structure. Given no output schema, this leaves some gaps for an agent trying to interpret results.

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 schema already fully describes the sole parameter as a 'TechRadar section slug' with an enum of valid values, so schema coverage is 100%. The description does not add any additional meaning beyond what the schema provides, so the baseline of 3 is appropriate.

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 clear verb and resource: 'Get TechRadar section headlines.' It adds that it returns fresh headlines from one public section hub page, which is specific. However, it does not differentiate from sibling tools like techradar_news or techradar_sections, so an agent might not know when to prefer this over those.

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 gives no guidance on when to use this tool versus alternatives. It does not mention techradar_news, techradar_sections, or other headline tools, nor does it specify any exclusions or prerequisites. The agent is left to infer usage from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
