Get QuokkaPix agent payment options

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

No annotations are provided, so the description carries full burden. It states it 'fetches live' payment options and explicitly says it does not sign, submit, or consume a payment, clarifying its read-only nature. It does not discuss side effects or rate limits, but for a simple fetch operation this is largely sufficient.

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?

Two sentences with no wasted words. The first sentence states the main purpose, the second lists what is fetched and what is not done. The description is front-loaded and efficient.

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 is a simple fetch with one optional parameter and no output schema, the description provides a complete overview of the purpose, usage timing, and data retrieved. It does not elaborate on output format but covers essential decision-making context for an agent.

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% as the only parameter (baseUrl) is fully described in the schema. The description adds no additional context about the parameter beyond what the schema already provides, so the baseline score of 3 applies.

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?

Description clearly states the verb 'Fetch' and the resource 'QuokkaPix agent payment options'. It lists the specific data returned (price, currency, rules, endpoints) and explicitly states what the tool does not do (sign, submit, consume payment), distinguishing it from sibling tools like explain_payment_flow and verify_unlock_token.

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?

Description explicitly says 'Use this before any paid batch/scenario run', providing clear context. It lists the kind of information discovered but does not explicitly mention when not to use it or name alternative tools. However, the 'does not' statement implies alternatives exist for payment actions.

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