sleeper_league_rosters

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

With no annotations provided, the description must disclose behavioral traits. It only states 'Get rosters' without mentioning authentication, rate limits, whether it returns all rosters or a single team's, or any side effects. The description adds minimal behavioral context.

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, concise sentence that is easy to read and front-loaded with the action. However, it is arguably too brief, missing opportunities to add useful context without becoming verbose.

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?

Given one parameter and no output schema, the description is incomplete. It does not clarify what the response contains, how to obtain the league_id, or any limitations. Additional context is needed for a basic understanding.

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 description coverage is 0%, and the description does not explain the 'league_id' parameter. The agent must infer its meaning from the name alone. The description adds no semantic value beyond the parameter name.

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 uses a specific verb 'Get' and resource 'rosters' for the Sleeper fantasy league platform. It differentiates from sibling tools like sleeper_league (league info) and sleeper_league_matchups (matchups) by focusing solely on rosters. However, it lacks details on the scope of rosters.

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 explanation of when to use this tool versus alternatives like sleeper_league or sleeper_players. No prerequisites mentioned (e.g., league_id from sleeper_league). The agent receives no guidance on context.

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