sportsbet_racing_multis_events

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

Annotations already declare the operation read-only and idempotent, and the description adds meaningful context beyond that: it works without a key, a SPORTSBET_REFRESH_TOKEN unlocks more data, and results are ordered as a next-to-jump feed. The vague 'unlocks more' keeps it from a 5.

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 compact and well structured: purpose first, then return shape, then auth. Every sentence adds useful information and there is no filler or repetition of schema content.

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 zero-parameter read-only tool with no output schema, the description covers the return fields, ordering, and auth requirements well enough to invoke correctly. Minor gaps are the unspecified meaning of 'unlocks more' and the exact time format, but neither blocks a correct call.

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?

There are zero parameters and the input schema already documents this completely. With no parameters to describe, the baseline of 4 is appropriate; the description does not need to add parameter-level meaning.

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 identifies the resource ('events available for racing multis') and the ordering behavior ('by start, next-to-jump style feed'). The verb is only implicit rather than explicit ('lists' is not stated), and it does not directly differentiate from sibling racing tools, so it falls just 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?

The phrase 'racing multis' plus 'next-to-jump style feed' gives enough context for when the tool is appropriate. However, no alternatives are named and there are no when-not-to-use conditions, so the agent must infer distinctions from sibling tool names.

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