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

Annotations already flag destructiveHint=true, non-idempotent and non-read-only, so the safety profile is covered. The description adds real context beyond that: the concrete consequence (loss of sign-in access) and the role-based precondition that blocks removing owners. It does not mention reversibility or re-invitation, but the key behavioral constraint is disclosed.

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, effect stated first and the precondition second, with no filler. The second sentence is slightly redundant in phrasing ('never removes an owner; the only Owner is never removed'), costing a point.

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 one-parameter destructive tool with annotations covering the safety profile and no output schema, the description supplies the two things an agent most needs: the effect on the member and the rule that owners cannot be removed. Return-value or error-shape details are not needed here.

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?

With a single parameter at 100% schema coverage, the schema already documents user_id and points to list_the_team as its source. The description adds no format or sourcing detail beyond what the schema provides, so the baseline of 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 ('take a person off this workspace') and immediately scopes the effect ('they can no longer sign in to it'). This clearly separates it from neighboring tools like change_a_members_role and invite_a_person without needing the schema.

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?

Provides a concrete when-not rule: owners are never removed by an admin, and the sole Owner can never be removed. It stops short of naming the alternative (change_a_members_role) for role adjustments, but the exclusion is explicit and actionable.

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