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

The description adds 'whitelisted public' and 'requested season' beyond the annotations' readOnlyHint and idempotentHint. However, it does not elaborate on what 'whitelisted' implies or how season is determined.

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?

Single sentence, directly stating the action and scope. No fluff.

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?

Though the tool is simple and has an output schema, the description fails to clarify how the 'requested season' is specified, as season is not a parameter. This omission could confuse an AI agent.

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 description provides no explanation of the league or player parameters. With 0% schema description coverage, the tool relies solely on the enum and type, leaving the agent uninformed about valid values or format.

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 it returns a public player profile for a season, distinguishing it from sibling tools like get_team_profile. However, it does not explicitly differentiate from other get tools.

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 guidance on when to use this tool vs alternatives. The description omits context such as prerequisites or conditions.

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