cigchat_subscriber_cart

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

With no annotations provided, the description carries the full burden. It does disclose an authentication requirement (Manage Flow scope), which is useful behavioral context. However, it does not explicitly confirm the operation is read-only, nor does it describe response behavior or edge cases, though 'Get' implies a read operation.

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 sentence that front-loads the core purpose ('Get subscriber shopping cart detail') and then adds the necessary auth scope. It is concise, with no filler or irrelevant information.

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 simplicity of the tool (one parameter, no nested objects, no output schema), the description is mostly adequate. It states the purpose and auth requirement. However, it does not describe the return format or any limitations, which an agent might need to know, but for a simple GET this is a minor gap.

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 schema already documents the single parameter 'user_ns' with a clear description ('Subscriber user_ns'), and schema coverage is 100%. The description adds no further meaning about the parameter, so it does not improve on the schema but also does not need to.

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 ('Get') and the resource ('subscriber shopping cart detail'), with the endpoint for reference. This distinguishes it from sibling tools that add, remove, or empty the cart, and from other subscriber-related actions.

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. The description does not mention related sibling tools (e.g., subscriber_add_to_cart, subscriber_remove_from_cart) or any conditions for choosing this tool, leaving the agent to infer usage purely from the name.

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