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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered and the bar is lower. The description adds an authorization requirement (manufacturers:write scope) that annotations do not convey, which is the kind of auth-context the rubric credits. It stops short of describing cascade/blocked-delete behavior for a referenced entity.

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?

Two short sentences, front-loaded with the action and immediately followed by the permission prerequisite. Nothing is padded or restated, so every sentence 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?

For a one-parameter delete tool with no output schema and annotations carrying the destructive/idempotent profile, the description covers the essentials. It omits the practically important case of a manufacturer still referenced by parts or assets, which is where a delete attempt would fail or cascade, leaving a real decision gap.

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 parameter with 100% schema description coverage ("Manufacturer ID", uuid format). The description's "by ID" merely echoes the schema and adds no format or sourcing detail, so the baseline 3 applies.

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 ("Delete a manufacturer") and narrows scope with "by ID", so an agent can distinguish it from get_manufacturer, update_manufacturer, and list_manufacturers without opening a schema. It does not differentiate itself from the many other delete_* siblings, but the resource name is specific enough to be unambiguous.

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?

Usage is implied by the verb plus the stated prerequisite ("Requires manufacturers:write scope"), which is genuinely useful for deciding whether the call is permitted. However, there is no explicit when-to-use/when-not guidance, no mention of alternatives (e.g., update_manufacturer or deactivating rather than removing), and no note on behavior when the manufacturer is referenced elsewhere.

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