Check upstream health

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds the useful fact that authentication is not required, but it does not mention that the call is read-only, free of side effects, or how the operational status is represented in the response. Transparency beyond the auth requirement is largely missing.

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 sentence that is front-loaded with the core purpose and immediately identifies the key requirement of no authentication. There is no redundancy or filler, and every word earns its place.

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 tool, the description adequately states the purpose and auth requirement. However, because there is no output schema and the description does not explain what a healthy response looks like or how an agent should interpret the result, the definition is not fully complete for an agent making decisions based on the response.

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 input schema has zero parameters and schema description coverage is 100%, so there is nothing for the description to explain. The baseline of 4 applies because no parameter documentation is needed for an empty schema.

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 a specific verb ('check') with a concrete resource ('operational status of OpenFootAPI'), making the tool's purpose unambiguous. This clearly distinguishes it from sibling data-access tools like openfoot_matches and openfoot_standings, which return domain data rather than service health.

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 provides no guidance on when to use this tool versus alternatives. It does not explicitly say to use it as a prerequisite before calling other endpoints, nor does it mention any exclusions. An agent must infer the usage context entirely from the tool name and the phrase 'without authentication.'

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