players

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

No annotations provided. The description states 'Every player' indicating it returns all players, but it does not disclose read-only nature, side effects, or requirements. The burden falls entirely on the description, which is insufficient.

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?

Extremely concise: a single sentence listing fields with no redundancy. Every word adds value.

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?

The description lists the output fields, which is helpful, but lacks explicit statement of the tool's action (e.g., 'Get player information'). With no output schema, the description should be more explicit about the return structure. Overall, minimally adequate.

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 100% (save_path has a detailed description). The tool description adds no parameter information, but the schema already covers it adequately, earning a baseline 3.

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 lists the fields returned for every player, which clearly implies a retrieval operation. However, it lacks an explicit verb like 'get' or 'list', reducing specificity. It does not differentiate from siblings such as 'friendships' or 'inventory'.

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 on when to use this tool versus alternatives. The description merely enumerates output fields without context about prerequisites or comparison to siblings.

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