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

Annotations only say destructiveHint=true and readOnlyHint=false; the description goes much further by revealing the call is non-mutating in practice ("Calling this changes nothing"), returns a preview plus a confirmation link, and that only the merchant can complete the removal. That two-phase preview/confirm semantics is exactly the kind of context annotations cannot convey.

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 purpose is front-loaded in the first sentence and the preview/confirmation disclosure is valuable, but the middle sentence about money being integer minor units is dead weight — this tool has no monetary parameter, and it reads like boilerplate carried over from other shipping tools.

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, the description usefully states what comes back (a preview of changes and a confirmation link), which is exactly what an agent needs to know for a one-parameter tool. It could say slightly more about what happens after the merchant confirms, but coverage is solid for this complexity level.

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?

There is a single `name` parameter and schema description coverage is 100%, so the schema already documents the matching behavior (case-insensitive). The description adds no parameter-level detail, which is the expected baseline when the schema fully covers the input.

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?

"Remove a delivery method" states a specific verb and resource, and the name makes it easy to separate from sibling setters like shipping_set_method or shipping_set_zones. It stops short of explicitly contrasting itself with those alternatives, so it is clear but not sibling-differentiated.

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 explains the mechanics of the call but never says when to reach for this tool versus shipping_set_method or other shipping configuration tools, nor are there any prerequisites or exclusions. Usage is only implied by the verb.

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