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

Annotations already declare destructiveHint=true, so the safety profile is known, but the description adds two pieces of non-obvious behavior: access loss is immediate and workspace-wide, and the call always returns a human approval link. The latter is especially valuable since it means the removal is gated rather than instant, which an agent could not infer from annotations alone.

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?

Three short sentences, zero filler, and the destructive consequence plus the approval-link behavior are placed up front before any lower-value detail. Nothing is wasted.

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?

An output schema exists, so return values need not be explained, and the description still flags the human approval link. For a single-parameter destructive tool with full annotation coverage, this is close to complete; only the auth/permission prerequisites for performing a removal are unaddressed.

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?

Only one parameter exists, and the schema already documents it at 100% coverage ('Member id or email'). The description's parenthetical restates that same accepted identifier forms without adding syntax or format detail, so the 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+resource ('Remove a member from the workspace'), names the accepted identifier forms (member id or email), and makes the scope explicit. An agent can distinguish this from siblings like fillo_revoke_agent or fillo_remove_connection_account without opening any 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?

The description conveys the effect (immediate loss of access to every project) which implies when it is appropriate, but it never states when to prefer this over alternatives such as fillo_change_member_role or any prerequisite/permission requirement. Usage is implied rather than guided.

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