List a Scaleway IAM User's grace periods

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 the explanation that grace periods are 'post-lock/deletion data-access windows' which clarifies the concept, but does not disclose additional behavioral traits such as pagination, ordering, or any side effects beyond what annotations already indicate.

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 sentence with a parenthetical clarification. It is front-loaded with the action and resource, and every word adds value without redundancy.

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?

The tool is simple (one required parameter, no output schema). The description explains the concept of grace periods and the read-only nature. However, it does not specify what the response contains (e.g., a list of objects with start/end dates) which could aid agent reasoning, making it minimally 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?

Schema coverage is 0%, so description carries full burden for parameter documentation. The description does not mention the user_id parameter, its format, or how to obtain it. While the title and context imply the parameter is the user's ID, explicit guidance is absent.

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 verb 'Read' (interpreted as list), the resource 'User's grace periods', and explains what grace periods are (post-lock/deletion data-access windows). This distinguishes it from sibling tools like scaleway_iam_list_api_keys or scaleway_iam_get_user.

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 implies usage context through its title and explanation, but does not explicitly state when to use this tool versus alternatives. For example, no mention that for general user details one should use scaleway_iam_get_user, or that grace periods are a specific concept only available via this endpoint.

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