sportsbet_racing_popular_srms

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, reducing the bar. The description adds 'Auth: none needed' and the return format, which are useful behavioral context beyond annotations. But it does not disclose data limitations, pagination, or the meaning of the 'Also answers' alias, so it is adequate but not rich.

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 brief and front-loaded, with only three lines covering purpose, return format, and auth. The 'Also answers this' line is vague and could confuse, preventing a perfect score, but overall the structure is clean and efficient.

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 read-only tool with 6 parameters and no output schema, it provides essential return format and auth info. However, it lacks explanation of how hierarchyLevel/ids map to races vs. meetings, what 'popular' entails, and the cryptic alias note. It is minimally viable but leaves gaps for a complex betting domain.

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% with well-described parameters, so the description is not required to compensate. It adds no extra parameter semantics beyond what the schema provides. The description's focus on 'popular' aligns with the 'popularsrms' parameter but does not explain relationships or usage nuances.

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 clearly states it returns 'Popular Same Race Multi (SRM) combinations for races / meetings' and provides a return format, establishing a specific resource and scope. It distinguishes from siblings by emphasizing 'popular' and mentioning entain_graphql_call and pointsbet_racing_srm, though this reference is cryptic. The purpose is evident and actionable.

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?

There is some implied guidance: use for popular SRMs across races/meetings, and the note about 'also answers' indicates potential overlap with other tools. However, it lacks explicit when-to-use vs. alternatives, exclusions, or conditions like event vs. meeting selection. The alias statement is too ambiguous to serve as clear guidance.

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