ping

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

No annotations are provided, so the description carries the transparency burden. It correctly conveys that the call is a non-mutating liveness check, but adds nothing about response shape, latency, or failure semantics — though for a ping the behavioral surface is inherently small and the output schema covers returns.

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 sentence that front-loads the purpose with zero filler. Nothing could be removed without losing the meaning, and nothing needs to be added for a tool this simple.

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?

With an output schema present, the return value needn't be explained, and with zero parameters there is no input surface to cover. The description is essentially complete for a liveness probe, missing only explicit usage timing.

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 takes zero parameters, so there is no parameter semantics to document and the baseline of 4 applies. The empty schema is consistent with the description, which implies no input is needed.

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 and resource: it verifies whether the MCP server is operational, which is a clear health-check purpose. It does not differentiate from siblings, but the siblings (buscar_empresa, investigar_empresa, etc.) are all domain search tools, so no real overlap exists to disambiguate.

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?

Usage is implied rather than stated: an agent can infer this is a connectivity/liveness probe, but the description never says when to call it (e.g., before a batch of other calls) or when not to. For a zero-parameter ping the omission is minor, but it is still inference rather than guidance.

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