list_user_groups

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

No annotations exist, so the description must carry the full burden. 'List all' indicates a read operation without filters, but it does not disclose behavior like authentication requirements, response volume, or any side effects. The existence of an output schema helps with return format, but the description itself adds minimal behavioral insight.

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 no wasted words. It conveys the action and the resource clearly, appropriate for a tool with no parameters and a straightforward purpose.

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 zero-parameter list tool with an output schema, the description is mostly complete. It states the exact resource and scope. However, given the lack of annotations, adding one sentence about typical use cases or safety could improve completeness, though it's not critical for this simple 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?

There are zero parameters, so the schema already covers everything. The description adds value by clarifying that the scope is 'all' user groups and defining 'user groups' as 'bandwidth profiles', which is helpful context that goes beyond the schema.

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' with the resource 'user groups' and parenthetical 'bandwidth profiles' to clarify the domain. It distinguishes from siblings like list_wlan_groups or list_firewall_groups by naming a distinct resource, though it doesn't explicitly contrast with them.

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 provided on when to use this tool versus the many sibling list_* tools. The description simply states what it does without giving context or exclusions, leaving the agent to infer based on the name alone.

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