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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose that the tool costs $0.05 USDC and bundles three services, but it does not explain whether this is a read-only lookup, whether payment is triggered immediately, what the response contains, or any restrictions or side effects. This is a significant gap for an unannotated 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?

The description is a single sentence with no filler: it names the package, lists its component services, and states the price. Every element earns its place and the most important purpose information is front-loaded.

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 that there is no output schema, no annotations, and three undocumented parameters, the description is not complete enough for an agent to invoke the tool correctly. It provides useful package context and pricing, but omits parameter semantics, expected return data, and operational details.

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% and the description does not mention inn, limit, or max_pages at all. It adds no meaning beyond the raw parameter names, so an agent cannot infer what values are valid for limit or max_pages or how they affect the report.

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 clearly identifies the tool as a counterparty-check/KYB-dossier package combining EGRUL, self-employed status, and a deep internet dossier. It lacks an explicit verb like 'fetch' or 'generate', but the package framing makes the purpose understandable and distinguishes it from the individual sibling services.

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 implies the usage context: use this when a full KYB/counterparty check with multiple data sources is needed in one paid call. It does not explicitly state when not to use it or point to sibling tools such as ru_research or inn_lookup for narrower needs, so guidance is only implicit.

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