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

No annotations exist, so the description carries the full burden. It usefully discloses cost ('FREE'), geographic scope (UK only), the result cap ('Top 3 notices'), and implicitly a read-only lookup. It does not say what happens when no notices are found, how fresh the data is, or what a notice record contains.

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?

One sentence, front-loaded with the value proposition ('FREE') and the core question, then the coverage details and result cap. Nothing is padded and nothing important is buried.

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 single-parameter read tool with no output schema, the description covers purpose, scope, and result volume adequately. It leaves the empty-result behavior and notice structure unexplained, which are minor but real gaps.

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?

Only one parameter with 100% schema description coverage, so the schema already explains 'Company name or number, e.g. 11877818'. The description repeats the same 'name or company number' fact without adding format or matching nuance (e.g. fuzzy name matching vs exact number).

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 names a specific verb (check) and resource (UK company against Gazette insolvency notices), and enumerates the notice types covered (winding-up petitions, liquidation, administration). It also bounds the result ('Top 3 notices'), so an agent knows exactly what it gets. It does not explicitly contrast with siblings like new_petitions or watchlist_check, which keeps it from a 5.

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 phrasing 'Has this UK company ... appeared in Gazette insolvency notices' frames the use case as a quick binary due-diligence lookup and 'Top 3' signals triage rather than exhaustive search. However, no alternatives (new_petitions, company_history, area_distress) are named and there are no stated exclusions or prerequisites, so usage must be inferred.

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