add_members_by_id_api_v1_channels

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'Add Members By Id', indicating a mutation, but lacks details on idempotency, authorization requirements, error handling, or side effects such as overwriting existing members.

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 extremely short (one phrase), which is concise but severely underspecified. It sacrifices informativeness for brevity, making it insufficient for the agent to understand the tool's functionality beyond the name.

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?

Given the tool has three parameters, no output schema, and many sibling tools, the description is incomplete. It fails to explain parameter roles, return values, or how this tool fits into the channel management workflow (e.g., whether it replaces or appends members).

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?

The description does not mention any parameters. With 0% schema description coverage, the agent must rely solely on the schema, which provides names and types but no explanations of what 'id', 'group_ids', or 'user_ids' represent or how they should be used together.

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 'Add Members By Id' clearly identifies the verb 'Add' and the resource 'Members' identified by ID, distinguishing it from the sibling 'remove_members_by_id_api_v1_channels' by the action. The target object (channel) is implied from the tool name, so the purpose is unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., other channel update tools). There are no prerequisites or context about when adding members is appropriate, leaving the agent to infer from the name alone.

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