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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds the constraint that only 'public' sections are valid and that the slug must be sourced from dailywire_sections, but gives no detail on freshness, ordering, or pagination of the returned headlines.

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?

A single sentence, front-loaded with the resource and scope, with the prerequisite trailing. No filler or redundancy.

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?

With one required parameter, full schema coverage, an output schema, and annotations covering safety, the description supplies what an agent needs: what it returns, the scope, and the source of valid section values. Only return-shape/ordering nuance is left implicit, which the output schema covers.

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% and the section property already enumerates documented slugs, so the baseline is 3. The description adds meaning beyond the schema by naming dailywire_sections as the authoritative source for valid values, reinforcing where the enum comes from.

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 gives a specific verb+resource (fetch current Daily Wire headlines) and constrains scope to one public section, which separates it from dailywire_article/news at a glance. It doesn't explicitly contrast itself with the sibling dailywire_news, so it stops short of a 5.

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 states an explicit prerequisite: the section value must come from dailywire_sections, which routes the agent to the right sibling before calling this tool. It does not spell out when to prefer headlines over dailywire_news, so it isn't fully exhaustive.

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