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

The description discloses authentication behavior (works without a key, with optional keys for more data) and the return shape. This goes beyond the annotations, which only indicate read-only, idempotent, and open-world hints.

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 concise, consisting of a clear statement of purpose, the return structure, and an auth note. It is well-structured and does not include unnecessary information.

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 tool, the description provides sufficient context: purpose, output structure, parameter description (via schema), and authentication. It does not explain every edge case, but the essentials are covered.

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?

The sole parameter 'jurisdiction' is adequately described in the schema as 'State jurisdiction.' The tool description does not add further clarification, but the schema coverage is complete, so a baseline score is appropriate.

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 what the tool does: it returns recently resulted sport events with final scores or settled markets. It also provides the return structure, making the purpose unambiguous.

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 does not provide any explicit guidance on when to use this tool over alternatives. It lacks context about exclusions, prerequisites, or specific scenarios where this tool is preferred.

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