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

No annotations exist, so the description carries the full disclosure burden. It adds only the provenance hint 'from official registries'; it says nothing about result caps beyond the schema's limit, pagination, whether registry coverage is uniform across countries, or how the optional api_key interacts with header-based auth.

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 no filler, and the scope qualifier ('European') lands early. It is efficient but arguably trimmed past the point of usefulness for an eight-parameter tool.

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?

Eight optional parameters, no annotations and no output schema leave the description responsible for explaining return shape and result limits, which it does not. An agent cannot tell from the description what a result contains or whether pagination is supported.

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%, so every parameter including enum-like values, ISO country codes, date format and comma-separation is already documented in the schema. The description adds no semantics beyond it, which meets the baseline-3 expectation for fully documented schemas.

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?

States a specific verb pair (search and filter) plus a precise resource (European insolvency, liquidation and bankruptcy filings from official registries). The domain is clear enough to separate it from siblings like search_distressed_auctions and search_succession_targets, though it never explicitly contrasts itself with them.

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?

No guidance on when to use this versus the sibling search tools, no mention that all eight parameters are optional, and no note about how to broaden a query when results are thin. Usage is only inferable from the tool name and the word 'search'.

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