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

No annotations are present, so the description carries the full behavioral burden. 'Get' implies a safe read, but nothing is said about error behavior for invalid IDs, rate limits, or what the response shape looks like. The peculiar 'notification_message' follow-up-failure parameter is not explained at all.

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?

A single efficient sentence with the resource and key return areas front-loaded. Nothing is wasted, though there is also very little content.

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?

For a simple single-resource read with full schema coverage and no output schema, the description is adequate but thin. It leaves the unusual notification_message semantics and failure behavior unaddressed, and doesn't indicate whether missing players produce an error or an empty result.

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 all three parameters are documented in the schema, making the baseline 3 appropriate. The description adds only the 'by player ID' framing for the required id and says nothing about the language or notification_message parameters.

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?

States a specific verb and resource ('Get detailed player information (stats, career) by player ID') and clarifies the returned content areas. It is distinguishable from siblings like get_team and get_match, but does not explicitly name an alternative or scope boundary.

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 gives no when-to-use or when-not-to-use guidance. There is no mention of how to obtain a player ID (e.g. via the 'search' sibling), nor of when get_team would be a better choice.

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