create-permission-group

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

No annotations are present, so the description must carry the behavioral disclosure burden. It only says 'creates' and does not mention required permissions, idempotency, duplicate-name behavior, errors, or what the response contains.

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?

A single sentence with no filler: the action is stated first and the parameter source is added as a helpful cross-reference. Every part contributes.

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 complex creation endpoint with a large nested request body and no output schema or annotations, the description is too thin. It omits response expectations, error scenarios, and any guidance about the required body fields, leaving the agent to discover key operational details from the raw 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?

The description adds value by telling the agent that productId comes from the List Products endpoint, which the schema description does not provide. However, it says nothing about the requestBody, the required name field, or how the many permission flags interact, so it only partially compensates for the 50% schema coverage.

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?

States a specific action and resource: creates a new Permission Group within a Product. The verb 'creates' clearly separates it from sibling tools like get/update/delete/list-permission-groups, and productId context anchors the operation.

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?

It implies when to use the tool (to create a permission group) and provides a useful prerequisite (obtain productId from List Products), but it never states explicit alternatives or when-not-to-use compared to update-permission-group or list-permission-groups.

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