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

No annotations (besides readOnlyHint: true) are contradicted. The description adds the behavioral trait that the document is prepared in the user's platform account for review and signature, which implies a non-final, pending action. However, it doesn't detail permissions, reversibility, or what exactly happens when invoked.

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 concise with two sentences, the first identifying the tool's output and the second providing a critical usage note. It is front-loaded and efficient, though it could benefit from more structure.

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 complexity of generating a signable memorial, the description is incomplete. It lacks details on input parameters, output format, how to retrieve the document, and the workflow. With no output schema, more completeness is expected.

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?

Schema coverage is 0%, meaning the description provides no information about the two parameters (api_key and referencia_calculo). This is a significant gap; the description must compensate but fails to do so.

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 it generates a signable memorial with an ANSI/NBR label, and emphasizes it is never autonomously issued by AI, clarifying its purpose as a human-reviewable document. While it doesn't explicitly differentiate from siblings, the name and description are sufficiently specific.

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 clear context that the tool should not be used for autonomous AI emission, implying manual review is required. However, it lacks explicit when-to-use vs. when-not-to-use guidance and does not mention alternatives among the listed siblings.

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