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

No annotations are provided, so the description must fully disclose behavior. It correctly indicates this is a read operation but lacks specifics on authentication requirements, rate limits, or what 'details' are returned (e.g., division, placement). The safety profile is implied but not explicit.

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 front-loaded with a clear purpose sentence but then becomes verbose by listing the endpoint and parameter details that are already present in the input schema. Some redundancy reduces conciseness.

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 lookup with three required parameters and no output schema, the description covers the basic purpose and required IDs. However, it lacks information about the return value (beyond 'Player details'), error conditions, or common use-case examples, which would make it more complete.

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%, meaning the description repeats the schema titles verbatim (league_id, season_id, player_id) without adding meaning such as example values, formatting rules, or relationships. The description adds no value beyond the schema for the 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?

The description clearly states 'Retrieve details of a player for a given league and season' and distinguishes this from sibling tools like faceit_getPlayer by specifying the need for league, season, and player IDs together. The purpose is specific and unambiguous.

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 says 'Use to look up a single player's division/placement within one season of a league', which implies appropriate context but does not explicitly exclude other use cases or mention alternatives among the sibling tools. No guidance on when not to use it.

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