get_payment_customization

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Fetch' and does not mention error handling, return format, permission requirements, or side effects. This is a significant gap for a tool without annotation support.

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 sentence with a clear verb and object, front-loaded with the core action. There is zero wasted wording, making it highly 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?

For a simple one-parameter getter, the description is adequate: it identifies the operation and the schema fully documents the parameter. However, with no output schema, it does not describe the return structure, but the tool is straightforward enough that this is not critical.

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 100% because the 'id' parameter has a detailed description with an example. The description adds no extra parameter semantics beyond 'by ID', which is already implied by the tool's name and schema.

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 uses the specific verb 'Fetch' with the resource 'payment customization' and the qualifier 'by ID', making it clear this tool retrieves a single object. This distinguishes it from siblings like get_payment_customizations (plural, list) and create/update/delete operations.

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 'by ID' qualifier establishes a clear context for single-object retrieval. However, it does not explicitly mention alternatives (e.g., 'use get_payment_customizations to list all') or when-not-to-use conditions, so a small gap remains.

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