cart_rule_create

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

The disclosure mentions validation is left to Voog and that invalid combos return a 422, adding context beyond annotations. Annotations show it's not read-only, destructive, or idempotent, but description adds behavioral nuance.

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?

Two sentences are concise and front-loaded with the main action. The second sentence adds structural details, though it could be slightly more streamlined.

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?

No output schema is provided, and the description does not mention return values. For a tool with 10 parameters and nested objects, more detail on response or side effects would be helpful.

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?

Despite 0% schema coverage, the description explains the inner structure of conditions and result, but only covers 2 of 10 parameters (conditions, result). Required fields are listed but not described individually.

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 explicitly states 'Create a cart rule' and provides the endpoint. It clearly distinguishes from sibling tools like cart_rule_delete, cart_rule_get, cart_rules_list, and cart_rule_update.

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 implies when to use (to create a cart rule) but does not state when not to use or provide alternatives. It gives details on the structure but lacks explicit usage guidance.

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