cigchat_subscriber_remove_from_cart

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

No annotations are present, so the description carries the transparency burden. It does add the required 'Manage Flow' scope and the DELETE HTTP method, which is useful context. However, it does not disclose behavior when variant_id is omitted, idempotency, or error handling, so it is only moderately transparent.

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?

A single, front-loaded sentence communicates the action, resource, endpoint, and auth requirement without fluff. Every word earns its place.

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 operation is simple, but the optional variant_id creates ambiguity about whether the tool removes a specific item or the entire cart. No return format is described, and the description does not clarify the consequences of calling it with only user_ns. Given the lack of annotations, this is a noticeable 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?

Schema description coverage is 50%: user_ns has no description and variant_id only shows an example. The description's phrase 'Remove item' does not explain how the parameters map to the operation, leaving the required user_ns and optional variant_id semantically unclear.

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 ('Remove item') and the resource ('subscriber shopping cart'), with the HTTP endpoint making the operation explicit. It distinguishes itself from sibling tools like add_to_cart and empty_cart by naming the specific removal action.

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 such as add_to_cart, empty_cart, or cart. The description does not mention use cases, prerequisites beyond the scope line, or exclusions, 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.
