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

No annotations exist, so the description must carry the full behavioral burden, yet it discloses only the AED 2 million threshold. It says nothing about how the 'financed' flag changes the verdict (a materially different rule in practice), whether the result is a boolean or an explanation, or any disclaimer that this is not legal advice.

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?

Two short sentences with the purpose first and the rule second; nothing is wasted and it is easy to scan. It is arguably under-specified rather than over-written, but the structure itself is clean.

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 two-parameter, schema-rich, no-output-schema tool, this is close to sufficient: the core rule and input meaning are conveyed. The gaps are around the financed pathway and the shape of the answer, both of which an agent would need to use the result confidently.

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 100%, so both parameters are already documented in the schema and the baseline is 3. The description reinforces the meaning of propertyValueAed by naming the threshold, but adds no interpretation of the 'financed' parameter, which is the one whose effect on the outcome is least obvious.

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 verb and resource ('Check if a Dubai property investment qualifies for UAE Golden Visa') plus the concrete decision rule (AED 2 million threshold), which is more than a restatement of the name. It does not, however, distinguish this tool from the near-identically named sibling 'golden_visa_eligibility', leaving an agent to guess which of the two to call.

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?

There is no when-to-use guidance, no statement of prerequisites (e.g. property already purchased vs. prospective), and no mention of the 'golden_visa_eligibility' sibling that appears to overlap. The only implicit guidance is the domain implied by the word 'investment'.

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