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

With no annotations, the description carries the full behavioral burden. It does disclose the return fields and adds a genuine caveat about how to read the transaction count, which is real transparency. It is silent, however, on what happens when the name is not found, whether matching is exact or fuzzy, and whether the lookup is case- or spelling-sensitive.

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 sentences, front-loaded with the tool's scope. The second sentence is slightly expansive but earns its place by pre-empting a likely misinterpretation of the transaction count.

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?

With no output schema and no annotations, the description must carry the return and edge-case load. It partially does so by listing the reported fields, but leaves the not-found/not-licensed outcome and name-matching rules unstated for a one-parameter lookup tool.

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% and there is a single required parameter, so the baseline of 3 applies. The description adds nothing about name-matching behavior (exact string, aliases, transliteration) beyond the schema's note that the name is as it appears on the licence.

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 resource (Dubai Land Department broker register) and enumerates exactly what the tool reports: licence status, broker number, company, and attributed transaction count. It is plainly distinguishable from its siblings, all of which are market-price tools, though it never explicitly names an alternative.

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?

Usage is implied by the licence-verification framing, and the closing note usefully warns that transaction counts are blank for newly licensed brokers and for those transacting under a colleague's number. There is no explicit statement of when to reach for this tool versus a sibling, nor of prerequisites such as exact-name requirements.

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