Show Payments Beneficiary

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

Annotations already provide readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds that it returns a JSON object and mentions required parameters and the endpoint, but does not elaborate on behavioral traits like pagination or rate limits beyond what annotations already convey. This adds minor 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 5 sentences, each serving a clear purpose: stating action, usage, return type, required params, and API reference. It is well-structured and front-loaded with the core purpose.

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 show endpoint with no output schema, the description states it returns a JSON object. It covers required parameters and API endpoint. However, it does not mention optional page/per_page parameters or return value structure. Given annotations cover behavioral aspects, it is mostly complete.

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?

Input schema has 100% description coverage, so the schema already documents parameters. The description lists required parameters but does not add new meaning beyond the schema. Baseline of 3 is appropriate.

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 'Show payments beneficiary' and 'fetch the full details of a specific Payments by its identifier,' specifying the resource (payments beneficiary) and action (show/fetch). It distinguishes from siblings like 'approve_payments_beneficiary' and 'list_payments_beneficiaries' by focusing on retrieving details of a single beneficiary.

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 includes 'Use this to fetch the full details of a specific Payments by its identifier,' providing context on when to use. It does not explicitly state when not to use or list alternatives, but the context of siblings and the specific focus on a single ID imply its appropriate use. Required parameters are also stated.

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