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

Annotations already declare destructiveHint=true and idempotentHint=true, so safety profile is covered. The description adds genuinely new behavioral context by naming the required authorization scope (service_areas:write), which annotations do not convey. It does not contradict anything, though it stops short of describing the effect on related records.

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 with zero filler; the action and its scope requirement are front-loaded and nothing is wasted.

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, un-nested delete with no output schema and annotations covering destructiveness and idempotency, the description supplies the missing piece (required scope). It is nearly complete, lacking only any note on failure behavior or what remains after deletion.

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 fully documented parameter (schema coverage 100% for the 'id' UUID), the schema already carries the semantic load, so baseline 3 applies. The description's phrase 'system class link' reinforces what the ID refers to but adds no format or resolution detail beyond the schema.

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 ('Remove') and a precise resource ('a system class link from a service area'), which unambiguously distinguishes it from siblings like delete_service_area, delete_system_class, and delete_service_area_site. An agent can identify the exact join-record deletion without opening the 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?

The description never says when to use this versus alternatives, nor does it note prerequisites such as the link having to exist or the parent service area/system class needing to remain. 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.
