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

No annotations exist, so description carries full burden. It discloses that rates are retail reference rates (not spot bullion prices), published at specific times (09:00, 13:30, 18:00 UAE time), and no authentication key is needed ('no key'). This provides useful behavioral context beyond a simple data retrieval.

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 with structured bullet points. It immediately states the core purpose and then provides key details. No superfluous words; every sentence adds value.

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?

Given zero parameters and the presence of an output schema, the description covers the data source, karat types, publication times, and distinction from spot prices. This is sufficiently complete for a simple retail gold rate 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?

The input schema has zero parameters and schema coverage is 100% trivially. The description adds value by explaining what the tool returns (gold rates by karat) without needing parameters, making the tool self-contained. Baseline 4 for no parameters 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 the tool provides today's Dubai retail gold rates in AED per gram by karat, specifying the karat values (24K, 22K, 21K, 18K, 14K) and source (Dubai Jewellery Group). It distinguishes itself from siblings like currency_rates or other financial tools by focusing on retail gold rates.

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?

No explicit guidance on when to use this tool versus alternatives, such as spot gold price tools or other currency converters. The description implies it is for retail rates but does not provide criteria for selection or note when not to use.

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