rent_estimate

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the output is an annual rent range but does not disclose limitations, such as whether the estimate is based on historical data, its accuracy, or if it applies to all areas. This lack of transparency is notable for a tool that provides estimates.

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 a single, concise sentence that conveys the core purpose without any extraneous information. It is front-loaded and efficient.

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 tool with two well-documented parameters and an output schema, the description is sufficient. It specifies the output is an annual rent range, which is adequate context. However, it could briefly mention that the estimate is for a full year or note any geographical scope, but overall it is complete given the tool's simplicity.

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%, with clear parameter descriptions including defaults and case-insensitivity. The description adds that the output is an annual rent range in AED, but does not provide additional parameter-level meaning beyond what the schema already offers. Baseline 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 clearly states what the tool does: provides an annual rent range in AED for a specific area and bedroom size. It uses a specific verb (estimates) and resource (rent range), and is distinguishable from sibling tools like 'school_fee_estimate' or 'corporate_tax_estimate'.

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?

The description implies usage for when an annual rent estimate is needed, but does not provide explicit guidance on when to use this tool versus alternatives, such as 'rera_rent_increase' or 'dewa_bill_estimate'. No exclusion criteria are mentioned.

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