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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety behavior is covered. The description adds genuine provenance context ('tracked on The Odds Gap', 'Not an official league record') that the annotations do not convey. It does not discuss ordering, depth of history, or whether the next game may be absent, so it is solid but not rich.

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?

Two short, front-loaded sentences with no filler; the resource is stated first and the provenance caveat second. Nothing is wasted, though the caveat is the only element that adds informational value.

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 and annotations cover the safety profile, so the description only needs to frame the resource and its data source, which it does. The one gap is that it never clarifies its relationship to sibling tools like past_game, but for a simple single-parameter lookup that is a minor shortfall.

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 is a single parameter with 100% schema description coverage ('The team as typed.'), so the schema carries the parameter semantics. The description adds no syntax, format, or matching-behavior detail beyond the schema. Baseline 3 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 names the specific resource (a team's finished games plus its next game) and scopes it to The Odds Gap, which separates it from a generic schedule tool. The implicit verb 'retrieve/list' is not stated outright, but the resource is unambiguous. The caveat 'Not an official league record' further sharpens what data is returned.

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?

There is no statement of when to use this tool versus siblings like past_game, game_lines, or slate, which plausibly overlap for game results. The 'Not an official league record' note is a provenance caveat rather than routing guidance. The agent must infer the use case from the description alone.

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