A3.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description usefully discloses that the response contains game cards plus source IDs and that those IDs are the join key to markets, but says nothing about coverage (which sports/leagues are 'featured') or freshness of odds.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero waste, and the chaining instruction is front-loaded after the purpose statement. Nothing is repeated from the schema or annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and no inputs, the definition covers what an agent needs to call correctly and how to continue. Only the meaning of 'featured' remains unstated, a minor gap for a zero-parameter endpoint.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters, so there is nothing for the description to disambiguate and the baseline is 4. The description correctly adds no fake parameter guidance.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Fetch') and resource ('featured odds game cards and source IDs') and names the downstream sibling yahoo_sports_odds_game, so an agent can distinguish it from yahoo_sports_odds_games/game. The scope word 'featured' is left unexplained, which slightly blunts precision.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The second sentence gives an explicit chaining rule: take a returned game ID into yahoo_sports_odds_game to get markets. There is no explicit when-not guidance or mention of the non-featured sibling yahoo_sports_odds_games, so the agent must infer the boundary.

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