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

With no annotations, the description must disclose behavioral traits on its own. 'List' implies a read-only operation but does not explicitly state that it makes no changes, nor does it mention authentication requirements, error behavior, or output format. This is insufficient for a tool with no annotation support.

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 with zero wasted words. It delivers the essential information efficiently.

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 one-parameter list tool, the description is passable but minimal. It lacks context about what the output will look like (users list, IDs, etc.) and does not mention prerequisites like being logged in or the access group needing to exist. Given no output schema or annotations, this is a clear gap.

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 schema covers the only parameter ('group') with a description, and the tool description reinforces its meaning ('in an access group'). However, no additional details are provided beyond the schema, such as naming conventions or whether the group name is case-sensitive. Baseline of 3 is appropriate due to 100% 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?

The description uses a specific verb ('List') and resource ('users in an access group'), clearly distinguishing it from sibling tools like ibmcloud_iam_access_groups (which lists access groups) and ibmcloud_iam_access_group_user_add (which adds a 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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or reference sibling tools such as the access group user add tool. Usage must be inferred solely from the tool name and description.

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