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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds that results are paged and that assigned forms/users are embedded in each record, which is useful shape information, but it says nothing about permissions, result caps, or total counts.

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?

Two telegraphic fragments with zero padding, and the payload contents are front-loaded. It is efficient, though the near-noun-phrase style leaves the actual action implicit.

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 one-parameter read-only list tool with no output schema, the field enumeration is the right kind of compensation. Still missing are whether all groups are returned or scope-filtered, and whether elevated permissions are required to see group membership.

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 description coverage is 100% for the single 'page' parameter, including the 100-per-page size and the next_page hint, so the schema does the heavy lifting. 'Paged' in the description reinforces but does not extend that.

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 fragment names the resource (user groups) and enumerates the returned fields (id, name, forms and users assigned), so an agent knows exactly what it gets back. It does not distinguish itself from adjacent list tools such as gocanvas_list_department_users or gocanvas_list_users, which is the main clarity gap.

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?

There is no statement of when to reach for this tool versus the many sibling list tools, and no prerequisites or exclusions. 'Paged' only hints at the paging workflow, which the schema already documents.

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