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

Annotations already declare readOnlyHint=true and destructiveHint=false, aligning with the description of a non-mutating health check. The description adds the context that the response is a 'static confirmation' and that the tool verifies server reachability, providing useful behavioral context beyond the annotations. No contradictions. It does not elaborate on network timeouts or error behavior, but for a simple ping this is sufficient.

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, front-loaded sentence: 'Health check. Returns a static confirmation that the Turnale MCP server is reachable.' Every word serves a purpose, with the tool's function stated immediately. No fluff or redundancy.

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 the tool's simplicity, no parameters, an output schema, and clear annotations, the description is fully complete. It covers the tool's purpose and outcome without unnecessary detail. No gaps remain.

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, and the schema is empty. The baseline of 4 applies since no parameter descriptions are needed. The description adds no parameter details, but there are none to explain.

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 identifies the tool as a health check that returns a static confirmation of server reachability. The verb 'returns' specifies the action, and the resource is the MCP server itself. This distinguishes it from all sibling tools, which are domain operations like tournament management.

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?

While the description does not explicitly mention alternatives or exclusions, the purpose is unambiguous: it is a health check. Given the sibling tools are all tournament-specific operations, there is no alternative for this simple connectivity test. The context makes it clear when to use the tool.

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