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

The annotations already declare this is a read-only, non-destructive, closed-world operation. The description adds useful context about what the groups contain (member counts and template association), but it does not mention ordering, pagination, empty results, or access constraints. With annotations covering safety, this is a reasonable but not rich behavioral disclosure.

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 two concise sentences and is front-loaded with the key information about what is listed. The second sentence adds domain context rather than call-critical detail, but it is brief and does not create clutter.

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 listing tool with no output schema, the description should clarify the shape of returned data. It states that each group includes teammate count and template, but it does not mention group identifiers or names, which an agent would need to follow up with update_group or delete_group. It is adequate but incomplete.

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 tool takes zero parameters, so the baseline is 4 per the rubric. There are no parameter semantics to clarify in the description, and the schema is empty by design.

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 identifies the resource (groups in the workspace) and what each entry includes (teammate count and associated template). It does not explicitly distinguish itself from related siblings such as list_teammates or get_workspace, which prevents a perfect score.

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?

Usage is implied by the tool name and the description's focus on listing groups, but there is no explicit guidance on when to choose this over alternatives like get_workspace, list_teammates, or get_workspace_template. It is adequate but leaves the agent to infer the right context.

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