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

Annotations already declare readOnly, idempotent, and non-destructive behavior, and the description adds useful context about billing, public-source data, and LGPD responsibility. However, the claim 'sem credenciais' is potentially misleading given the schema includes login_cpf, login_senha, pkcs12_cert, and pkcs12_pass, so the description is not fully transparent about the role of these parameters.

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 composed of three short, front-loaded sentences. The first sentence states the core purpose, while the remaining sentences cover pricing, data source, and compliance without excessive padding 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?

No output schema exists, so the description should indicate what the consultation returns or what 'andamento' includes, but it does not. It also fails to explain four optional parameters, leaving a significant gap for a tool with five parameters and no structured output information.

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 description coverage is 0%, so the description must compensate, but only 'protocolo' is inferable from the text as a REDESIM protocol identifier. The optional credential-related parameters (login_cpf, login_senha, pkcs12_cert, pkcs12_pass) are entirely unexplained, and the statement 'sem credenciais' adds confusion rather than resolving their purpose.

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 opens with a specific verb and resource: 'Acompanha o andamento de um protocolo REDESIM na JUCESP' and clarifies the covered business types (abertura, alteração ou baixa de empresa). This clearly differentiates the tool from the general sibling tools like authenticate, connect, and marketplace.

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?

It provides clear contextual guidance: the tool is hosted by the platform, requires no credentials, uses prepaid credit, and returns the same non-confidential data available to Brazilian citizens. It does not explicitly name when-not-to-use alternatives, but the context is sufficient for the given sibling set.

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