newsweek_headlines

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

No annotations are provided, so the description carries the behavioral burden. It does disclose that results are 'fresh' and come from a 'public category page,' implying a read-only, low-auth operation. It does not describe pagination, result shape, or rate behavior, but for a simple headline fetch this is moderate transparency.

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 and front-loaded, but it repeats the same object ('Newsweek section headlines') in both sentences. The first sentence and second sentence could be merged, so not every word earns its place, though overall it is still compact.

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 one-parameter tool with no output schema, the description is mostly complete: it states the source ('public category page'), freshness, and that the result is headlines. It does not detail output fields or pagination, but 'headlines' is self-descriptive and the required section parameter is fully enumerated in the schema.

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%: the lone 'section' parameter has an enum and description ('Newsweek section slug'). The description adds no further parameter detail, examples, or caveats, so it does not improve on what the schema already provides.

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 clear action verb ('Get') and names the resource ('Newsweek section headlines'), so an agent can tell this is a section-scoped headline fetch. It doesn't explicitly differentiate from siblings like newsweek_news or newsweek_sections, but the 'section' parameter and 'public category page' phrase make the scope reasonably clear.

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?

Usage is implied: when you need Newsweek section headlines, call this tool. It also adds 'from the public category page,' which suggests no special access. However, it gives no explicit when-not-to-use guidance or comparison to sibling tools like newsweek_article, newsweek_news, or newsweek_sections.

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