create_delivery_option_generator

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

No annotations are provided, so the description carries full burden. It states the action 'Create a new...' but does not disclose additional behavioral traits such as required permissions, idempotency, side effects, return format, or error behavior. This is a significant gap for a mutation tool with no annotation coverage.

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, concise, and front-loaded with the action and resource. No unnecessary information is present; 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?

With no output schema and no annotations, the description should explain return values and additional context, but it does not. The tool has two parameters and a clear schema, yet the description fails to clarify what 'delivery option generator' means or what the functionId refers to beyond the schema. This leaves the agent without critical information for successful invocation.

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, with both functionId and metafields documented. The description adds no extra parameter semantics, but since the schema already explains all parameters, a baseline score of 3 is appropriate.

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 (create) and the resource (delivery option generator), and distinguishes it from sibling tools like update/delete/get delivery option generator. The phrase 'using a Shopify Function' adds useful context about the underlying mechanism.

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 usage: use this tool to create a new delivery option generator. However, it provides no explicit guidance on when to use it versus alternatives, no prerequisites, and no exclusions. It falls short of explicitly naming alternatives or conditions, so it only meets the 'implied usage' level.

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