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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds the useful constraint that only 'public' sections are valid, but says nothing about freshness, volume, or pagination. With annotations carrying the safety profile, this is an adequate but not rich disclosure.

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 front-loaded sentence: the resource and scope come first, then the validation constraint. Nothing is wasted.

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?

An output schema exists, so return values need no explanation. For a one-parameter read tool the description covers the key gating constraint; it is slightly thin on what 'public section' entails but nothing an agent needs to invoke it correctly is missing.

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 0% and the bare 'section' string has no enum, so the description must compensate. It does so by naming cbssports_sections as the authoritative source of valid values, which is more than the schema offers, though it still does not list or enumerate accepted sections.

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 specific verb and resource ('Current CBS Sports headlines') and scopes it to a single public section. It does not explicitly contrast itself with the closely-named sibling cbssports_news, so the boundary between the two is left to inference.

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?

Clearly states the precondition that the section value must come from cbssports_sections, which routes the agent through the correct discovery tool first. No explicit when-not-to-use guidance or alternative for other CBS Sports content is given.

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