Create JazzCash Hosted Checkout

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

No annotations are provided, so the description carries the full burden. It discloses that the tool returns a form and that amount is in paisa, but it does not describe side effects, idempotency, or authentication requirements. Some behavioral context is given but insufficient for a 4.

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, front-loaded with the core action, and contains no redundant phrases. Every sentence contributes to understanding the tool's purpose and key detail (paisa conversion).

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 10 parameters and no output schema, the description is incomplete. It does not describe the return structure beyond mentioning action URL and hidden fields, nor does it cover potential errors, required configuration, or consequences of invoking the tool. The tool's complexity demands more context.

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 description coverage is only 20%, with only two parameters having descriptions. The description adds that amount is in PKR paisa (already in schema) and that txn_ref_no defaults to T+timestamp (beyond schema), but does not explain the ppmpf_1-5 fields or return_url. The description adds minimal value.

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 builds a signed Hosted Checkout form that redirects the customer to JazzCash to pay, and returns action URL and HTML snippet. This verb+resource combination uniquely identifies the tool among siblings like charge mobile wallet or inquire transaction.

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 checkout scenarios but does not explicitly state when to use it versus alternatives, nor does it mention when not to use it. No comparison to sibling tools or prerequisites are provided.

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