Rank all Yahoo baseball players

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

Annotations indicate readOnlyHint=true, and the description adds behavioral context: no league-specific context, returns up to 25 players per call. No contradictions. While it doesn't detail all nuances, the additional context beyond annotations is commendable.

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?

Three sentences: purpose, differentiation, limitation. No superfluous text. Front-loaded with core action, then key distinctions. Highly efficient.

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?

Lacks description of return format (no output schema) and does not cover error conditions or edge cases. However, given the tool's simplicity and read-only nature with well-defined parameters, it is minimally adequate. Could be improved by noting typical response structure.

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 100%, so baseline 3. The description adds marginal value by mentioning 'Yahoo stat or ranking key' and 'returns up to 25 players'. However, it does not elaborate on parameter formats or usage beyond the schema.

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 the tool ranks players by a Yahoo stat or ranking key, specifying the resource (current game's player pool) and verb (rank). It effectively distinguishes itself from the sibling tool `rank_players` by noting it is not league-specific.

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?

Explicitly contrasts with `rank_players` by stating this tool is not league-specific and lacks ownership/waiver context. Provides a clear when-to-use guideline and mentions the 25-player limit, aiding selection among siblings.

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