get_legal_status

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

No annotations are provided, so the description must disclose behavioral traits. It lists possible output values, which is helpful, but it does not mention whether the tool is read-only, requires authentication, or has any side effects. There is no indication of error behavior if required parameters are 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 extremely concise with two sentences. The first sentence presents the output values upfront, and the second provides a critical usage requirement. No extraneous information is included.

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?

While the output schema exists (context signals indicate it), the description does not leverage or reference it. It explains the return values but omits context about error handling, prerequisites (e.g., authentication), or how this tool fits into a workflow alongside siblings. The missing enforcement of the required parameter in the schema adds ambiguity.

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. It only adds that at least one parameter is required, without explaining what 'inn' and 'ogrn' represent, their formats, or constraints. This minimal addition does not adequately compensate for the lack of schema descriptions.

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 tool name 'get_legal_status' combined with the description clearly indicates that the tool retrieves the current legal status from a list of enumerated values (active, liquidating, etc.). It is distinguishable from sibling tools like 'check_inn' and 'check_ogrn' which likely validate identifiers, and 'get_directors_history' which retrieves different data. However, the description does not explicitly contrast with these siblings.

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 states that at least one of 'inn' or 'ogrn' is required, which provides a key usage constraint. However, it does not explain when to use this tool versus alternatives such as 'check_inn' or 'check_for_red_flags'. The guideline is present but incomplete.

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