getPlayerData

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

With no annotations, the description carries the full burden, but it only states the read action and the data categories. It does not disclose whether authentication is required, whether this is a safe read-only operation, or what the response format looks like. This is minimal disclosure for a tool with zero structured context.

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 a single concise sentence, front-loaded with the action and resource, and includes useful enumerations. There is no filler or redundancy, making it easy to parse quickly.

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 zero parameters, no annotations, and no output schema, the description is the sole source of context. It covers the general content (stats, equipment, settings) but omits critical details such as whether it returns the current player, whether authentication is needed, and any edge-case behavior. It is adequate but not 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?

The tool has zero parameters, so the description's mention of 'stats, equipment, and settings' clarifies the scope of the returned dataset. Schema coverage is complete (empty schema), and the description aligns with the baseline expectation for no-parameter tools.

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 uses the specific verb 'Get' with the resource 'player profile data' and enumerates content areas ('stats, equipment, and settings'), distinguishing it from sibling getters focused on specific resources like getCoaches or getRoutes. It loses a point for not clarifying whether this is the current authenticated player or a player ID parameter.

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 the many other get* tools in the sibling list. It also does not mention any prerequisites, context, or exclusions, leaving the agent to infer applicability from the name alone.

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