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

The annotations already establish that this is a read-only, idempotent operation with no open-world side effects. The description adds meaningful behavioral context by clarifying that it only provides links and never submits anything on the user's behalf. It does not describe the exact return format, but that is less critical here.

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 sentences and front-loads the resource being provided. The enumerated list is dense but necessary to convey the available link categories, and the second sentence adds the key usage and safety boundary without waste.

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 simple read-only link-provider with full schema coverage and no output schema, the description covers what the tool returns, when to use it, and the critical constraint that it does not perform submissions. Nothing essential for correct invocation is missing.

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?

There is one optional language parameter, and the schema fully documents it with an enum, default, and purpose. The description does not mention the lang parameter or add meaning beyond the schema, so the baseline score of 3 is appropriate.

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 states a specific resource: links to Riviera Maya Elite pages for property buying, mortgage pre-qualification, travel planning, contact, and listing correction/removal. It is clear what the tool provides, though it does not explicitly differentiate itself from the sibling directory and guide tools.

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 gives a clear usage condition: use when the person wants to act, and send them to the page. It also states the boundary that the server never submits anything, but it does not name alternative tools or explain when not to use this one.

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