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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds that results are 'current' (recency) and scoped to 'one public section', plus the dependency on bleacherreport_sections. No rate limits or auth details, but the bar is lower with annotations present.

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?

Two concise clauses separated by a semicolon, with scope and requirement front-loaded. No redundant or wasted words.

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 definition covers purpose, scope, and parameter sourcing, and safe-read behavior is covered by annotations. An output schema exists so return values need no explanation. Minor gap: it does not explicitly compare to bleacherreport_news or bleacherreport_article, but overall it is sufficient for this simple, single-parameter tool.

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 already lists the documented section slugs. The description adds a constraint not in the schema: the section value must come from bleacherreport_sections, which helps the agent know how to source the parameter.

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?

State a specific verb-resource combination ('headlines') and scopes it to one public section, and names the sibling tool that supplies the required section value. An agent can distinguish this from bleacherreport_news, bleacherreport_article, and bleacherreport_sections without opening schemas.

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?

Explicitly requires the section to come from bleacherreport_sections, giving a clear prerequisite and alternative tool for obtaining the argument. However, it does not state when to prefer this over bleacherreport_news or bleacherreport_article, and offers no exclusions.

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