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

Annotations already declare readOnlyHint=false, openWorldHint=false, and idempotentHint=false, so the safety profile is largely covered. The description adds the confirmation-flow requirement, which is useful, but says nothing about reversibility, whether the member loses access immediately, or what happens to their data. Note that the annotation destructiveHint=false sits uneasily with an outright member removal, though the description itself does not contradict 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?

Two short sentences with the action front-loaded and the prerequisite second. Nothing is wasted, though the second sentence is thinner than it could be for a tool gated by a confirmation token.

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 mutating tool with no output schema, the definition is adequate but thin: it does not say whether the confirmToken comes from a failed call to this same tool, what happens post-removal, or what errors to expect. The critical prerequisite is named, so an agent can proceed, but with gaps.

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 100%: userId, confirmToken (with its CONFIRMATION_REQUIRED origin), and organizationId (approved workspace only) are all documented in the schema. The description's mention of confirmToken only restates what the schema already explains, so baseline 3 applies.

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: 'Remove a member from the workspace.' That is clearly distinct from siblings like invite_member, list_members, update_member_role, and revoke_invite without needing to open the schema. It stops short of explicitly naming the nearest alternative (update_member_role), so it is not a 5.

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 only usage signal is the confirmToken prerequisite, which is implied rather than explained as a workflow. There is no guidance on when to remove vs. demote (update_member_role) or when removal is inappropriate, but the intended use case is inferable.

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