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

No annotations are provided, so the description carries the burden. It discloses that no API key is needed, which is useful, and 'health check' implies a read-only operation. It doesn't describe what unhealthy responses look like or how to interpret results, but the output schema partially covers return values.

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, tightly-worded sentence that conveys purpose and authentication requirements with zero wasted words. Perfectly sized for a zero-parameter health check tool.

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 zero-parameter, no-auth health check with an output schema present, the description is largely sufficient. The output schema presumably documents the health status shape, so the description needn't repeat it. Could mention expected HTTP/status codes, but this is a minor gap for a simple health probe.

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 there is nothing to document. The description's note that no API key is needed adds value by managing agent expectations about authentication.

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 states a specific verb+resource ('Check public PokéWallet API health') and usefully notes no API key is needed. It doesn't explicitly distinguish from siblings, though the tool's purpose is naturally distinct from card/search tools.

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 implies a diagnostic/health-check usage context but provides no explicit guidance on when to use this vs alternatives, or what action to take based on the result. No exclusions or alternative tool references given.

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