create_cart_transform

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

No annotations are provided, and the description only restates the creation intent without disclosing side effects, permissions, idempotency, or return behavior. It does not add behavioral context beyond the action itself.

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?

Single concise sentence that is front-loaded with the action and resource, with no wasted words. It 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?

For a simple create tool with a fully described schema, the description is minimally adequate. However, it lacks usage guidance and behavioral transparency, and the absence of an output schema means return values are unexplained, but the low complexity keeps the gap moderate.

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 input schema has 100% description coverage for both functionId and metafields, so the baseline is 3. The description's phrase 'using a Shopify Function' maps to functionId but adds no additional semantics or format details.

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 uses the specific verb 'Create' with resource 'cart transform' and adds 'using a Shopify Function', clearly distinguishing from sibling update/delete/get cart transform tools. It is direct and 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?

The description implies the tool is for creating new cart transforms but does not explicitly state when to choose it over update_cart_transform or delete_cart_transform. No alternatives are named, and prerequisites like needing an existing functionId are not mentioned.

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