remove_group_members

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

With no annotations, the description must disclose behavioral traits. It states the mutation ('Remove') but offers no details on idempotency, error handling, permissions, side effects, or what happens to non-existent members. The agent is left without knowledge of important behaviors beyond the basic action.

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?

A single sentence with no redundancy. The verb and resource are front-loaded, and there is zero wasted wording. For a tool of this simplicity, the length is appropriate.

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 mutation tool with two parameters and no output schema, the description is minimal. It does not mention return values, success/failure indicators, or edge cases, which could be important for an agent to handle correctly. The basic purpose is clear, but behavioral context is lacking.

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 input schema provides descriptions for both parameters (group_id and members) with 100% coverage. The description adds no extra parameter information, so the schema fully handles parameter meaning. This meets the baseline for high schema coverage.

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 states 'Remove one or more members from a group' – a specific verb and resource. It differentiates from the sibling 'add_group_members' via the verb 'remove', though it does not explicitly name the alternative or expand on scope.

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 provided on when to use this tool versus alternatives or any exclusions. The description simply states the action without context, prerequisites, or conditions for use. There is no mention of when to prefer this over adding members or other operations.

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