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

Annotations already declare destructive=true and non-idempotent, and the description earns credit beyond that by documenting the authorization requirement (current owner only, `workspaces:write` scope) and the counterintuitive semantics that the departing owner keeps a retained access level. It does not state whether the transfer is reversible or what happens to the departing owner's other permissions, leaving a real gap for a destructive mutation.

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?

Four tightly packed sentences, front-loaded with the action and the two preconditions before the parameter caveat. There is minor redundancy between "the numeric access-level id the CURRENT (departing) owner will keep" and "typically a regular admin/member level," but no filler.

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, non-idempotent mutation with no output schema, the description covers preconditions, auth scope, and the ambiguous parameter — enough to call it correctly. It omits what the response contains and what happens to the departing owner's sessions/other grants, which would be useful for a destructive operation.

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%, so baseline is 3; the description adds genuine disambiguation by stressing in caps that `resultingOwnerAccessLevelId` is the level the CURRENT/departing owner retains — an easy-to-invert semantic — and by naming a discovery endpoint for its values. It adds no help for the `account` and `workspace` parameters, but those are already fully documented in the schema.

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 ("Transfer workspace ownership") plus the exact constraint that the recipient must be an "existing member," which separates it from generic role-change tools like pm_change_member_role. It never names an alternative sibling by name or says what it is NOT, so it stops short of full sibling 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?

Gives clear preconditions: only the current owner may invoke it and the target must already be a member, which tells the agent when the call is valid and what failure modes to expect. It also routes the agent to /v1/workspaces/{ws}/access-levels to obtain a required id, but it does not contrast with alternatives such as pm_change_member_role or pm_remove_workspace_member.

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