Create a user group

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the description doesn't need to restate that this is a write operation. The phrase 'Adds a team to the workspace' adds minimal context about scope, but it doesn't disclose potential error behavior, idempotency, or permission requirements. The description adds limited value beyond the annotations.

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 no fluff or repetition. It is front-loaded and efficient, but the use of 'team' instead of 'user group' slightly detracts from precision. Overall, it is concise without being under-specified to the point of uselessness.

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 create tool with two well-documented parameters and no output schema, the description is minimally adequate. It communicates the core action and workspace scope, but it leaves gaps such as what happens if a group with the same name exists, whether admin rights are needed, and how success is reported. Given the tool's simplicity, this is acceptable but not exceptional.

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 both parameters ('Group name' and 'Workspace id' with fallback details), so the schema already explains them fully. The description does not add any additional meaning or context for the parameters, resulting in the baseline score.

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 states a specific action ('Adds a team') and target ('workspace'), which aligns with the create_user_group function. However, it uses 'team' instead of 'user group', which could cause slight ambiguity when compared to the tool name and title, though the intent is still clear.

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 guidance on when to use this tool versus alternatives like clockify_update_user_group or clockify_add_user_to_group. There is no mention of prerequisites, use cases, or exclusions, leaving the agent without clear direction.

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