validate_beneficiary

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

No annotations provided, so description must disclose behavior. It states it returns validation errors and implies it is non-destructive (validation step), but lacks details on side effects, security requirements, or whether it modifies state.

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?

Single sentence is concise but lacks structure: no front-loading of key information, no separation of purpose from details. Every sentence earns its place but could be structured better.

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?

With 11 parameters, no output schema, and no annotations, the description is inadequate. It does not explain parameter dependencies, required combinations, or validation rules, leaving the agent underinformed for complex inputs.

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 0%; description provides no explanation for any of the 11 parameters, leaving the agent to infer meaning solely from names and schema. This is a critical gap.

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?

Clearly states it validates beneficiary parameters before creating, distinguishing it from sibling tools like 'create_beneficiary' and 'verify_beneficiary'. Uses specific verb 'validates' and resource 'beneficiary parameters'.

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?

Explicitly says 'before creating', guiding the agent to use this tool prior to creation. However, no explicit when-not-to-use or alternatives among siblings for validation of other resources.

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