Behavior2/5

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

Annotations declare readOnlyHint: false, indicating a mutation. The description confirms creation but adds no further behavioral context—e.g., whether the operation is reversible, what happens to existing groups, or if it returns the created group. It does not contradict annotations but provides minimal value beyond the read-only hint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single brief phrase, but brevity here is under-specification, not effective conciseness. It contains no front-loaded key details and every sentence (there is one) adds no value beyond the tool name. It is not structured to aid agent comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complex schema with nested objects and custom fields, alongside a large sibling set with many group-related operations, this description is grossly inadequate. It does not cover required fields, typical usage patterns, or any behavior that would help an agent use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description provides no parameter information whatsoever. It fails to explain the required pathParams (format enum) or the bodyParams group object, including fields like name, user_ids, custom_fields, and custom_field_values. An agent would have no insight into what these parameters mean or how to construct them.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create group' is essentially a restatement of the tool name. It names a verb and resource but provides no elaboration on what a group is or what distinguishes creation from updating or deletion. It does not explicitly differentiate from siblings like updateGroup or deleteGroup, relying solely on the verb to imply purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool instead of alternatives such as updateGroup, deleteGroup, or addUserToGroup. No context is given about typical scenarios, prerequisites, or conditions that would make this the appropriate choice.

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