dailystaruk_headlines

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

With no annotations, the description carries the full behavioral burden. It adds one valuable behavioral disclosure: photo galleries are omitted because they lack readable article bodies. However, it does not mention response shape, pagination, freshness limits, or other operational behavior, so the disclosure remains partial.

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 short, front-loaded with the core action, and avoids unnecessary detail. The second sentence is slightly redundant with the first, but it adds the 'fresh', 'public', and 'one section' qualifiers, and the final sentence about photo galleries is useful context.

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?

The tool is simple and the schema fully covers the required section parameter, but there is no output schema. The description says headlines are returned but does not describe the structure of those headlines, error behavior, or whether metadata like URLs and dates is included, leaving some ambiguity for an agent.

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 description coverage is 100%, and the single parameter is fully described in the schema as a Daily Star (UK) section slug. The description reinforces that the tool works on 'one' section but does not add meaningful information beyond the enum-driven schema.

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 action ('Get') and the resource ('Daily Star (UK) section headlines'), and it adds useful scope ('one public Daily Star (UK) section'). It is distinct from the sibling article/author/sections tools, though it does not explicitly differentiate itself from dailystaruk_news or other headlines tools.

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 when to use the tool: when you need fresh headlines from a selected Daily Star (UK) section. It provides clear context but does not explicitly state when not to use it or name alternative tools such as dailystaruk_article or dailystaruk_news.

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