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

Annotations already declare readOnly, idempotent, non-destructive and open-world, but the description adds real behavioral context beyond them: access/delay/metered usage follow the connected account, a single bounded request with no background polling or automatic retry, and an explicit empty-result caveat. These are genuinely useful traits an agent could not infer from the annotations.

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?

Purpose is front-loaded, but the remainder reads as concatenated boilerplate clauses ('No wagers, account changes or guarantee of returns') that carry little selection value for this specific tool. It is not bloated, but several clauses do not earn their place.

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 not be explained, and the coverage/metering caveats are helpful. Still, for a single required parameter with no schema description at the top level, the description leaves parameter usage entirely to the schema.

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 reported at 0% for the top-level structure, and the description adds nothing about the sportID parameter or its path nesting. Only 'Use returned canonical IDs' touches the data model, and that concerns outputs rather than the input 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?

States a specific verb and resource (get divisions for a sport), which is clear enough to act on. However, it does not distinguish itself from the sibling v2GetDivisionsBySport, so an agent cannot tell which version to pick from the description alone.

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?

Contains scattered operational guidance ('Use returned canonical IDs', 'never infer coverage from an empty result') but no explicit when-to-use statement and no routing against the many sibling list/get tools, notably v2GetDivisionsBySport. The affiliate-27 exclusion is a constraint, not usage guidance.

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