get_company_details_uid

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses that no Zefix authentication is required and that the UID Webservice is used exclusively, but it omits other relevant traits such as return format, rate limits, or exactly what 'detailed company information' encompasses.

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 two efficient sentences, front-loaded with the core purpose followed by the auth constraint. Every sentence earns its place, though the data-source phrasing is slightly technical.

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?

For a simple single-parameter read operation with a fully described schema, the definition covers purpose and authentication adequately. However, with no output schema, it could help by clarifying the scope of 'detailed company information' (e.g., which fields or sections are returned).

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 100% with a single well-documented 'uid' parameter (format and pattern). The description adds no parameter meaning beyond what the schema already provides, so the baseline score of 3 applies.

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 clear verb+resource ('Get detailed company information') and adds the data-source qualifier ('using only the UID Webservice'). This is more specific than a generic lookup, but it does not explicitly differentiate from the similarly named sibling 'get_company_by_uid' or explain why one should be preferred.

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 statement 'This does not require Zefix authentication' implicitly suggests a usage condition (choose this when Zefix credentials are unavailable), but it does not state when to use versus alternatives or provide explicit exclusions. Guidance is implied rather than stated.

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