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

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered. The description adds the precondition that the target must be an active member, which is useful, but it does not state permission requirements or whether admin promotion/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?

A single efficient sentence with the key action front-loaded and no filler. Nothing is wasted, though the sentence is terse enough to leave meaning implicit.

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 destructive 3-parameter mutation with no output schema, the description covers the action space but omits prerequisites, permissions, and irreversibility. Annotations carry the safety signal, so the remaining gap is moderate rather than severe.

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 carries the full burden. It maps the two enum values to intent ('make an admin' / 'remove'), which is marginally helpful since the enum names are already self-documenting, but it says nothing about organizationId or userId beyond their self-evident names.

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+resource ('Make an active Team member an admin or remove a member from the Team'), covering both enum actions clearly. It is distinguishable from invite_team_member and update_team_invite by scoping to existing members, but it never names or contrasts those siblings explicitly.

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 description implies a precondition ('active Team member') but gives no explicit when-to-use guidance, no alternatives, and no exclusions. An agent cannot tell from this text alone when to choose update_team_member over invite_team_member or update_team.

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