removeUserFromGroup

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

The annotation readOnlyHint=false already indicates this is a mutating operation, and the description aligns with that. However, the description adds no additional behavioral context such as permission requirements, reversibility, side effects, or failure modes. With annotations only covering the read-only hint, the description carries responsibility for deeper disclosure and fails to provide it.

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 extremely short and efficiently phrased, but the brevity crosses into under-specification. It is not a model of concise clarity; it omits critical usage and parameter information, making it more of a placeholder than a helpful description.

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 tool with a nested parameter structure and no output schema, the description is grossly incomplete. It does not explain the meaning of format, how to provide identifiers, or what the response looks like. Even basic operational context is missing, leaving an agent without sufficient information to succeed.

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 0%, so the description must compensate by explaining parameters, but it does not. The schema requires format, groupId, and userId inside pathParams, none of which are mentioned. An agent relying on the description alone would have no idea how to construct the call correctly.

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 'Remove user from group' uses a specific verb and resource, clearly distinguishing the core action from siblings like addUserToGroup. It is not a tautology and immediately conveys the operation's intent.

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 given on when this tool should be used versus alternatives. The sibling list includes addUserToGroup and getGroup, but the description does not mention any conditions, prerequisites, or exclusions that would help an agent choose this tool over others.

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