Get League Overview

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

No annotations are provided, so the description carries the behavioral burden. The verb 'Get' implies a read-only operation and the description states the returned content (league settings and current standings). It does not disclose authentication requirements, data freshness, or response shape, but for a simple overview tool this is a reasonable baseline.

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 a single, front-loaded sentence with no filler or redundant phrasing. Every part adds value: the actor perspective, the resource, and the included data.

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 low-complexity tool with one fully documented parameter and no output schema, the description is nearly complete. It states what the tool returns and the perspective involved. Minor gaps such as authentication expectations do not meaningfully impede correct invocation.

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 coverage is 100%, and the league_id parameter is already well described with an example format. The description does not add parameter-level meaning, but none is needed since the schema fully documents the only 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?

The description clearly identifies the action ('Get') and resource ('commissioner's overview of a fantasy league') and lists the included content: league settings and current standings. It is specific and unambiguous, though there are no sibling tools to differentiate from, so it does not earn the top score.

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 implies when the tool is useful—when a commissioner needs league settings or standings—but it does not state explicit conditions, prerequisites, or alternatives. With no sibling tools, the lack of exclusion guidance is acceptable, yet still only implicit.

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