remove_broadcast_members

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

With no annotations provided, the description carries the full burden of behavioral transparency. It only states the basic action without mentioning permissions, idempotency, irreversibility, or side effects—similar to the 'update_drive' example, which scored 2 for lacking such details.

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?

The description is a single concise sentence that earnestly states the core functionality without unnecessary words or filler. It is appropriately sized and front-loaded.

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 simple 2-parameter mutation with no output schema, the description is minimally viable. It clearly identifies the action, but lacks behavioral caveats (e.g., cannot remove the owner, restrictions on removal) that would improve completeness for an agent unfamiliar with the tool's constraints.

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 100%, with both parameters (list_id and member_ids) adequately described. The tool description adds no extra semantic meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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?

The description clearly states the action: 'Removes members from a broadcast list.' It specifies the verb (removes), resource (members), and target (broadcast list), effectively distinguishing it from sibling tools like 'add_broadcast_members' or 'list_broadcast_members'.

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 provides no explicit guidance on when to use this tool versus alternatives. The only implicit signal is the presence of siblings like 'add_broadcast_members', suggesting usage for removal rather than addition, but no explicit conditions or exclusions are given.

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