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

With no annotations at all, the description carries the full burden, and it does disclose meaningful behavior the agent could not otherwise know: the recipient needs no account, and contact details are gated to members. It stops short of stating whether generating the link requires broker authentication, whether the link expires or is reusable, or what exactly is returned, which are real gaps for a link-producing 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?

Two short sentences with no filler, and the illustrative example is embedded efficiently rather than given its own line. The opening is slightly indirect because it leads with the artifact rather than the action, but nothing is wasted.

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 tool with no output schema, the description should at minimum make clear that the return value is the link itself; it only implies this. The recipient-side privacy behavior is covered well, but link lifetime, reusability, and whether caller auth is required are omitted, leaving moderate 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?

Schema coverage is 100%, so the baseline would be 3, but the description adds genuine value with the worked example "2BR Al Reem, budget 2M," which shows the expected free-text phrasing of the question parameter beyond the schema's abstract wording. The 1,000-character limit is left to the schema, which is fine.

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 the artifact produced ("a link that opens BrokersLynk's free search with a question already run") and gives a concrete example query, so the effect is inferable. However, it never states the action with a verb such as "generate" or "create a shareable search URL," and it does not distinguish this tool from the sibling abu_dhabi_market, so the agent must infer the operation from the noun phrase.

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 implicit context that the link is meant to be handed to a client who sees live matches without an account, which hints at the sharing use case. But there is no explicit when-to-use, no when-not-to-use, and no reference to the only sibling tool, abu_dhabi_market, so an agent has no stated rule for choosing between them.

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