create_mobile_account_payment

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

The description adds 'Money-moving and non-idempotent' and specifies return fields (pp_ResponseCode/pp_ResponseMessage). The annotations already declare non-idempotent and non-read-only, so this adds useful context beyond the annotations, without contradiction.

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 concise sentences, front-loading the core purpose. Every sentence adds value, though it could briefly mention the output structure for completeness.

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?

With 6 parameters and no output schema, the description lacks detail on the full return structure and prerequisites. It does not explain potential errors or safety considerations for a money-moving operation, making it incomplete.

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?

All parameters are described in the schema (100% coverage), so the description adds little beyond clarifying that amount is in PKR and that MWALLET uses CNIC digits. This is adequate but not transformative.

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 verb 'Create' and the specific resource 'CNIC-enabled JazzCash Mobile Account payment', including the MWALLET detail and last 6 CNIC digits. This distinguishes it from sibling tools like create_payment.

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 provides no explicit guidance on when to use this tool versus alternatives like create_payment or refund_payment. It mentions 'Money-moving and non-idempotent' but does not clarify context or exclusions.

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