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

With no annotations, the description fully discloses non-obvious behaviors: the category parameter selects stat sets (General/Goalkeeping), the pageSize parameter is ignored, and pagination uses totalPages/currentPage/isLastPage. It lacks an explicit statement that it's a read-only operation, but this is implied.

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 well-structured and front-loaded with the main purpose. It includes a critical NOTE, return format, and an example. No words are wasted, though it could be slightly more compact by reducing the stats detail.

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 no output schema, the description provides a detailed return format including all fields. It covers the main functionality and important caveats. However, it does not mention any optional filtering or sorting beyond the listed parameters, which might be useful for completeness.

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 0%, so the description compensates by explaining the `category` parameter's role in selecting stat sets and the `page` parameter's pagination logic. It does not explain `locale` or `seasonId`, but seasonId is implied by context (season required). The description adds meaningful value 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 retrieves every player in a season with identity and full Opta stats, distinguishing it from other Serie A tools that might only return player info or team stats. It uses specific verbs and resources, and the 'no separate squad call needed' differentiates it from multi-step alternatives.

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 provides clear usage context, including the caveat that 'category' is not a position filter and that pageSize is ignored. It implies the tool replaces separate squad+stats calls, but does not explicitly name alternatives or state when not to use this tool.

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