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

Annotations already declare destructiveHint=true, readOnlyHint=false and non-idempotent, so the safety profile is covered. The description adds useful context beyond that: the permission requirement (owner or admin) and that a user may remove themselves. It does not discuss consequences for the removed member or whether the removal is reversible.

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?

One compact sentence with the permission constraint front-loaded and no filler. Every clause carries information.

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 two-parameter mutation with no output schema, the description covers permission and self-leave but leaves parameter formats and post-removal behavior unstated. Adequate but with clear gaps given the total lack of schema descriptions.

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 coverage is 0% and both parameters are required with no descriptions anywhere. The description doesn't clarify whether 'group' and 'member' are IDs, handles, or names, nor what format is expected, so the semantics gap is unaddressed.

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?

States a specific verb and resource ('take a member out of the group') plus the self-leave variant, so the action is unambiguous. It does not explicitly contrast with nearby siblings like group_members (listing) or group_invite_revoke, so it stops short of full differentiation.

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?

Adds an actor precondition ('Owner or admin') and notes the self-leave case, which implies context of use. However, it never says when to prefer this over group_invite_revoke or how to check membership first, so guidance is implied rather than explicit.

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