create_automatic_discount_free_shipping

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

Discloses automatic application without code and criteria-based eligibility, but no annotations exist. Does not address combining discounts, overriding behavior, or side effects of setting destinationAll vs. countryCodes.

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 sentence is concise and front-loaded with key info. Could be slightly longer to include more context without becoming verbose.

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 10 parameters, no output schema, and no annotations, the description is too brief. Lacks explanation of response, required criteria logic, and limitations like maximum one free shipping discount per order.

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 coverage is 60% (6/10 params have descriptions). The description adds no additional parameter meaning; does not explain how criteria like minimumSubtotal and destinationAll interact or whether they are exclusive.

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?

Clearly states verb 'create' and resource 'automatic free shipping discount'. Distinguishes from siblings like create_automatic_discount_basic (not free shipping) and create_code_discount_free_shipping (requires code).

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 on when to use this tool versus alternatives like create_automatic_discount_basic or create_code_discount_free_shipping. Missing context about prerequisites or typical use cases.

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