cigchat_subscriber_create_many

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

With no annotations, the description carries the full burden. It discloses the required auth scope and the phone/email requirement, which are useful behavioral constraints. However, it does not describe potential outcomes (e.g., partial failures, duplicate handling, idempotency) or what the response contains, which is important for a bulk creation tool.

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?

One sentence, front-loaded with the action, and includes only essential additional info (auth requirement and input constraint). No wasted words or repetition of schema details.

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?

The schema provides rich descriptions for the users parameter, and the description covers the core action and scope. However, for a complex bulk-creation tool with no annotations and no output schema, the description lacks details on behavior under edge cases, error handling, and return values. It is minimally viable but not fully complete.

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 the baseline is 3. The description adds meaningful semantics by clarifying that 'phone or email is required' (at least one), which is clearer than the schema's confusing anyOf/required structure. This directly helps the agent construct valid requests.

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 states the action ('Create new subscribers') and the resource clearly. It includes a key constraint ('phone or email is required') and the endpoint. However, it does not explicitly distinguish from the sibling tool cigchat_subscriber_create, relying on the tool name's 'many' to imply bulk operation.

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 a prerequisite (requires 'Manage Flow' scope) but no guidance on when to use this tool versus alternatives like cigchat_subscriber_create for single creation. There is no mention of alternatives or exclusions, only an implicit bulk capability from the name.

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