laliga_player_stats

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

The description includes a return structure, which aids understanding of the tool's output. However, it does not disclose behavioral traits such as read-only status, authentication needs, or rate limits. Since no annotations are provided, the description carries the full burden but only partially fulfills it.

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 concise: one sentence plus a return structure. It efficiently conveys the core purpose. However, it could be slightly expanded without becoming verbose to improve clarity.

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 the tool's simplicity (one parameter, no output schema), the description is mostly adequate. However, it lacks explanation of what 'Opta stats' include and the meaning of the return fields. More context would help an agent use the tool correctly.

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 mentions 'by SLUG' but does not explain what a slug is, how to obtain it, or any constraints (e.g., format, required values). With 0% schema coverage, the description should provide more detail to compensate, but it falls short.

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 retrieves 'One player's Opta stats[] by SLUG'. The verb 'get' is implied, and the resource is specific to a single player's stats. However, it does not explicitly differentiate from sibling tools like 'laliga_player' or 'laliga_players_stats', though the singular form and 'stats' provide some distinction.

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 is provided on when to use this tool versus alternatives such as 'laliga_player' or 'laliga_players_stats'. There is no mention of prerequisites, limitations, or context for usage.

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