whatsms_admin_create_voucher

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It only says 'create a new voucher', which implies a mutation but does not explain side effects, required authorization, potential failures, or what happens to existing vouchers. This is insufficient for a create operation.

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 concise sentence with no wasted words. It clearly states the verb and resource. While it could be more detailed, it is appropriately short for a simple create action, though slightly under-specified.

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?

Given there are no annotations and no output schema, the description is too sparse. It does not explain what a voucher is, what fields or values are expected, or any behavioral outcomes. The complexity is low due to zero parameters, but a create operation typically needs more context to be useful to an agent.

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?

The input schema is empty with additionalProperties true, meaning there are zero defined parameters. Per the baseline for 0 parameters, the description does not need to explain individual parameters. However, the description does not clarify that the schema accepts arbitrary properties, but since no parameters exist, a baseline of 4 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 a specific action (create) on a specific resource (voucher) in the WhatSMS system. It distinguishes from sibling tools like delete_voucher, get_vouchers, and redeem_voucher by implying the creation action. However, it lacks additional scope details such as what kind of voucher or any constraints.

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?

No guidance is given on when to use this tool versus alternatives. There is no mention of prerequisites, differences from create_package/create_role, or any context that would help an agent decide to use this tool. The description is a bare statement without usage context.

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