Update Payments Beneficiary Classification

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

Annotations already indicate the tool is readOnlyHint=false, destructiveHint=false, idempotentHint=false. The description adds that it returns the modified object, but does not disclose additional behavioral traits such as permission requirements, side effects, or error conditions. With annotations covering the basics, the description 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 concise with 3 sentences plus API endpoint info. It is front-loaded with the main action and required parameters. However, the phrase 'Updates the specified Payments and returns the modified object on success' is somewhat redundant given the tool name and purpose. Overall, it is 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?

There is no output schema, and the description only states 'returns the modified object' without specifying the response structure or fields. For a mutation tool, the agent would benefit from knowing what the response contains. This lack of detail reduces completeness for a tool with 3 parameters and no output schema.

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%, so the baseline is 3. The description lists required parameters but does not add semantics beyond what is in the schema. It does not explain the purpose of each parameter or provide examples. The description adds no additional meaning.

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 verb 'Updates' and specific resource 'early pay classification for a payments beneficiary'. It specifies the action and the resource, distinguishing it from other payment-related tools like approve_payments_beneficiary. The inclusion of required parameters and API endpoint adds precision.

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 tells when to use the tool ('to update an existing Payments') and notes that only supplied fields are changed, but it does not provide explicit guidance on when not to use it or alternatives. Given the large sibling list, more explicit differentiation would be helpful, but the description is adequate.

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