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

With no annotations, the description carries the full burden, and it does disclose the paid/subscriber gating ('PRO', corroborated by the access_token param) and the time-window scoping. It says nothing about result volume, ordering, radius defaults, or rate/pagination behavior, leaving real gaps for a mutation-free but commercially gated data 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 dense sentence that front-loads the resource and scope, then the use cases. The terse 'PRO.' prefix is efficient, though the parenthetical field list and audience list make it slightly overloaded.

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?

No output schema and no annotations mean the description should be more complete. It covers what is returned conceptually and the postcode/days dimensions, but omits limit behavior, defaults, response shape, and how results differ from sibling insolvency tools.

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 coverage is only 20% (only access_token documented), so the description must compensate. It does explain days ('last N days'), postcode ('near a UK postcode'), and implicitly radius, but 'limit' and the radius unit/default are never addressed, so coverage remains partial.

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?

Names a specific resource (corporate insolvency notices: liquidations, administrations, winding-up orders) with an explicit geographic and temporal scope, so the agent knows exactly what data comes back. It lacks explicit differentiation from siblings like new_petitions or insolvency_check, which likely overlap on insolvency events.

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 lead-gen audience list (asset buyers, insolvency practitioners, recruiters, landlords) implies a prospecting use case, which is helpful context. But there is no explicit when-to-use versus new_petitions/insolvency_check, and no exclusions or prerequisites beyond the implicit 'PRO' tier marker.

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