get_league_overview

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

No annotations are provided, so the description technically carries the burden, but as a zero-parameter read tool there is little behavior to disclose. It lists what it returns, yet says nothing about auth requirements, rate limits, or whether the data is live versus cached.

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 sentences, front-loaded with the purpose before the field list. Minor redundancy between 'high-level overview' and the enumerated fields, but no wasted space.

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?

A zero-param read tool with an output schema needs little more than a statement of purpose; the description provides that and notes the key contents. Nothing critical is missing, though it could route the agent away from the overlapping settings tool.

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 tool takes no parameters, so there is no parameter syntax the description needs to compensate for. Baseline 4 applies for a parameterless tool.

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?

States a specific verb ('Get') and resource ('league overview') and enumerates the fields returned, so the agent knows it is a summary/snapshot tool. However, it does not differentiate itself from the sibling 'get_league_settings', which also covers league settings, leaving genuine overlap unaddressed.

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?

No when-to-use guidance is given and no alternative is named. The phrase 'high-level overview' loosely implies it is a quick snapshot versus a detailed settings call, but the agent must infer this, and the overlapping 'get_league_settings' sibling is never mentioned.

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