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

With no annotations, the description carries the behavioral burden and does supply important legal context: this is a substitution test, not an exemption. However, it does not state the return format, assumptions, or how the optional boolean conditions affect the outcome, leaving key behavioral details undisclosed.

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 tight sentences that front-load the legal test and follow with the key caveat that Cyprus has no audit exemption. There is no redundant or filler text.

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 five parameters, no annotations, no output schema, and only partial schema descriptions, the definition is not complete enough for reliable invocation. It explains the legal purpose but omits how to interpret the result and how the optional conditions change eligibility.

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 only 40%, and the description mentions none of the five parameters. The schema documents the two required financial parameters, but the three optional booleans about group aggregate limits, consolidated accounts, and consecutive years are not explained anywhere, so the description fails to compensate for the low coverage.

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 gives a specific legal test: applying article 152A of the Companies Law Cap. 113 to decide whether a Cyprus private company may use an ISRE 2400 review instead of a statutory audit. It clearly distinguishes this from sibling lookup/compliance tools by framing it as a substitution test, not a general obligation lookup.

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?

It clearly implies the use case: a Cyprus private company considering a review engagement instead of a full audit. The note that there is no audit exemption in Cyprus adds useful context, though the description does not explicitly name alternatives or exclusions.

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