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

Annotations already cover readOnly, idempotent, openWorld, and non-destructive hints. The description adds substantial operational context: metered access follows the connected account, empty results do not imply missing coverage, one bounded request with no polling/retry, Affiliate 27 exclusion, and no wagers/account changes/return guarantees.

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 purpose is front-loaded, but the first sentence runs on and the description stacks several boilerplate clauses. It could be tightened without losing essential context.

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 simple read endpoint with annotations and an output schema, the description covers operational constraints (metering, retries, empty results) and exclusions. It lacks when-to-use guidance relative to similar siblings, but the core call is adequately described.

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%, and the single nested teamID parameter is only labeled 'Normalized team ID' in the schema. The description's 'Use returned canonical IDs' is a useful semantic hint about where to source the ID, but it never names teamID or clarifies the nested path requirement, so it only partially compensates.

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 verb+resource 'Get players for a team' is specific and distinguishes from single-player tools like v2GetPlayerByID by scope. It does not explicitly name or differentiate against any sibling, so it stays at 4.

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 description offers usage context ('Product data or price calculation') and a sourcing rule ('Use returned canonical IDs'), but never states when to prefer this tool over alternatives such as v2GetPlayerStatsByTeam or v2GetTeamByID. Guidance is implied rather than explicit.

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