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

No annotations are provided, so the description carries full behavioral burden. It hints at the data source (the company dossier) but says nothing about permissions, behavior for un-enriched companies, pagination, or whether the list can be empty. That leaves meaningful behavioral gaps for a data-extraction tool.

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 front-loaded sentence with the action and resource up front and no filler. It is efficient, though extremely short given the tool's undocumented parameter.

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?

An output schema exists, so return values need not be explained. However, with no annotations and an undocumented required parameter, the description leaves gaps around prerequisites (enrichment state) and the meaning of the cnpj input that an agent would need to call it correctly.

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 single 'cnpj' parameter is undocumented in both schema and description. The phrase 'de uma empresa' only loosely implies cnpj identifies the company, and no format or validity information is given, leaving the required parameter under-specified.

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 ('Lista') and resource ('os produtos/serviços') and scopes it to a company's dossier, which distinguishes it from company-listing siblings like list_companies and search_companies. It is clear, though it never explicitly names an alternative tool to differentiate itself.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites (e.g., the company must already have been enriched), and no exclusions stated. The agent must infer the scenario entirely.

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