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

No annotations are provided, so the description carries the full burden. It does not state that removal is destructive/irreversible, what permissions are required, whether the member loses access immediately, or what happens to resources they owned — all critical 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?

A single short sentence with the scope front-loaded and no filler. It is efficient, though the parenthetical is slightly elliptical ('id de account.members' is terse rather than explanatory).

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 tool with no annotations and no output schema, the description should cover required permissions, irreversibility, and the result of the call. None of that is present, leaving an agent to guess at the consequences of invoking it.

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 the single parameter 'user_id' has no description in the schema. The description partially compensates by pointing to 'account.members' as the source of the id, but it does not specify the expected format (UUID, email, numeric id) or whether it is the membership id versus the user id.

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?

Names a specific verb ('Tira' / removes) and resource ('um membro do workspace'), so the operation is unambiguous. It does not explicitly contrast with the sibling invite_member, but the verb alone makes the direction of the operation clear.

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?

There is no guidance on when to use this versus alternatives, no prerequisites (admin role?), and no note about what happens to the removed member. The only usage hint is the parenthetical about where the id comes from, which is parameter guidance rather than tool selection guidance.

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