isw_initialize_payment

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

No annotations exist, and the description fails to disclose key behavioral traits such as side effects (e.g., creating a payment record), idempotency, or required permissions. It mentions that the endpoint receives kobo and requires confirm, but does not explain why confirm must be true or what happens upon success/failure.

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 extremely concise: two sentences with no redundancy. Every word 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 10 parameters, 3 required, a nested object (extra), no output schema, and no annotations, the description is far too minimal. It omits expected behavior, return value, and prerequisites. For a payment initialization tool, this is severely lacking.

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 low (30%), and the description only adds clarity for the conflicting amountNaira/amountKobo parameters by stating the endpoint uses kobo. Other critical parameters like customerId, transactionRef, and redirectUrl remain unexplained beyond their schema types.

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 initializes a Quickteller payment, specifying the payment provider. It provides the verb 'initialize' and resource 'Quickteller payment', but could be more precise about what 'initialize' entails versus completing a 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?

No guidance on when to use this tool versus alternatives like isw_pay_bill or isw_single_transfer. The only usage hint is 'Requires confirm: true', which is more a requirement than a usage context.

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