etsy_payment_get

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

The annotation readOnlyHint: true is present, so the description's 'Get' aligns. However, the description adds no further behavioral context such as side effects, error conditions, or output structure. Since annotations already declare read-only, the description does not contradict but adds minimal extra value.

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 a single concise sentence with no wasted words. However, it is under-specified; it could benefit from additional context without becoming verbose. It is adequate but not exemplary.

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?

For a tool with two required parameters and no output schema, the description lacks completeness. It does not explain what constitutes a 'payment', what fields are returned, or any usage constraints. This is insufficient for confident use compared to the richer sibling descriptions (assuming they exist).

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?

With 0% schema description coverage, the description should compensate. It mentions 'by ID' but does not explain the two required parameters (shop_id and payment_id) or their roles beyond the field names. The description adds little meaning beyond what the schema names imply.

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 'Get a specific payment by ID' clearly states the verb (get) and resource (payment) and the method (by ID). However, it does not explicitly differentiate from sibling tools like etsy_payments_list or etsy_payments_by_receipt, which also deal with payments but with different scopes.

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 guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., having a payment ID) or scenarios where other tools might be better suited.

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