whatsms_admin_get_vouchers

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

No annotations are provided, so the description carries the burden. It adds behavioral context by specifying that the operation is a 'List' (implying read-only) and mentions 'optional pagination', which is useful. However, it does not disclose pagination mechanics, response format, or any safety guarantees beyond the verb.

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, front-loaded sentence that states the action and resource immediately. Every word is informative, with no redundancy or filler.

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 list tool with no output schema or annotations, the description adequately covers the core behavior ('List all vouchers') and notes the existence of pagination. It lacks deeper details like return structure or default page size, but these are not critical for a basic admin listing operation.

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 zero defined parameters in the schema, the baseline is 4. The description adds a meaningful hint by referencing 'optional pagination', indicating that a pagination parameter may exist, even though it doesn't name the parameter or describe its format.

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 action ('List all') and the resource ('vouchers in the WhatSMS system'), making it specific and distinct from sibling tools like get_users or get_packages. This leaves no ambiguity about what the tool does.

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 intended usage is implied by the verb 'List' and the resource 'vouchers', but the description offers no explicit guidance on when to prefer this over alternatives or how to handle pagination. No exclusions or alternative tool references are provided.

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