shipping_methods_list

Read-onlyIdempotent

Retrieve a complete list of all shipping methods, including nested options for parcel-machine carriers such as Omniva and SmartPost.

Instructions

List all shipping methods (GET /admin/api/ecommerce/v1/shipping_methods). Read-only. Response includes the full options[] nested list for parcel-machine carriers (Omniva, SmartPost, …) — expect multi-KB payloads per method.

Behavior4/5

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint. Description adds valuable context about response containing full options[] nested list and expected multi-KB payloads, which helps agent anticipate performance implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences: first states purpose and endpoint, second provides crucial behavioral note. No filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequately covers purpose and response characteristics for a simple list tool, but fails to document the sole required parameter 'site', which is a significant gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 0% description coverage for the single required 'site' parameter. Description does not explain what 'site' represents, leaving agent to guess its purpose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states action 'List' and resource 'shipping methods', includes endpoint path. Differentiates from siblings as no other tool targets shipping methods.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description implies usage for reading shipping methods but does not provide explicit guidance on when to use vs alternatives or when not to use.

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