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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered; the description usefully adds what is *not* destroyed ("SKUs it already generated stay on the products") and the bearer-token auth requirement. It stops short of saying whether deletion is permanent/undoable or what happens to an unknown ID, which keeps it out of 5 territory.

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?

Three short sentences, zero filler, with the action and the ID scoping front-loaded before the side-effect caveat. Nothing repeats what the annotations say.

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 one-parameter destructive delete with no output schema, the description covers action, side effect on generated SKUs, and auth. It leaves out permanence/undo and not-found behavior, which an agent would want before firing a destructive call, so it isn't fully complete.

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?

With a single parameter at 100% schema description coverage, the schema already defines "id" as the “SKU template ID to remove”; the description's "by its ID" restates it without adding format, range, or sourcing guidance. Baseline 3 applies since the schema does the work.

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?

States a specific verb and resource ("Remove a SKU template by its ID") that unambiguously maps to one row of the delete-* sibling family; an agent can tell it apart from delete-segment, delete-store-category, and from get-sku-template without opening a schema.

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?

There is no when-to-use guidance, no statement of prerequisites beyond the auth note, and no pointer at alternatives (e.g., editing a template instead of deleting it) or at how to enumerate IDs first via get-sku-templates. The only context is the ID requirement, which the schema already carries.

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