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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and external-data reach are covered. The description adds the 'public section' constraint, implying no auth or non-public content, but little beyond that (no pagination, freshness window, or result shape).

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?

One sentence, front-loaded with the purpose followed immediately by the constraint on the parameter. No filler or repetition.

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?

Output schema exists, so return values need no explanation, and the critical input constraint is stated. Complete for a simple list tool, though it could have differentiated itself from bleacherreport_news.

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 0% and the lone 'section' parameter has no schema description, so the description carries the burden. It usefully tells the agent the valid source of section values (bleacherreport_sections) and that it must be a single public section, adding real meaning over the bare string type.

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?

States a clear verb+resource ('current Bleacher Report headlines') scoped to one public section, which distinguishes it from bleacherreport_article. However, it never explicitly contrasts with the sibling bleacherreport_news, so an agent must infer the boundary rather than being told.

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?

Gives a concrete prerequisite: the section value must come from bleacherreport_sections, which routes the agent to the right discovery tool first. It stops short of naming when-not-to-use or an alternative to bleacherreport_news, so no exclusions are offered.

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