create_verified_vendors_order

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

Annotations indicate write and open-world behavior. The description adds context by explaining the payment initiation, failure conditions if prerequisites are missing, and the return value structure, which goes beyond annotation hints.

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 front-loaded with purpose and important notes, then lists parameters. It is slightly verbose by repeating schema descriptions, but still efficient and well-structured.

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 the tool's complexity (7 params, conditional requirements, payment initiation) and availability of output schema mention, the description covers purpose, prerequisites, conditional fields, and return shape. Missing details on payment failure handling are acceptable as output includes payment status.

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%, but the description adds critical preconditions: table_number needed for inhouse, delivery_address for delivery, and that these must be asked before calling. This semantic guidance is not in the schema.

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 places an order with a food/goods vendor and initiates mobile money payment via BulkClix. It distinguishes from siblings like get_verified_vendors (listing) and place_merchant_order (likely for non-verified or different flow).

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 includes an important prerequisite note about collecting required fields before calling, and conditional requirements for order_type. However, it does not explicitly compare with sibling tools or state when not to use this tool.

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