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. The description adds a genuinely useful detail not in the annotations – the required purchase_orders:write scope – but says nothing about what happens to the parent purchase order, whether the delete is soft or hard, or error behavior.

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, zero filler, and the core action is front-loaded ahead of the prerequisite. Nothing is padded or repeated from the title.

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 full annotation coverage and no output schema, the description supplies purpose plus the auth prerequisite, which is close to sufficient. The remaining gap is that the effect of the removal on related records is never stated.

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?

Schema description coverage is 100% for the single 'id' parameter (UUID format, 'Purchase order link ID'), so the schema carries the semantics. The description adds no further detail about the identifier, which is the expected baseline when the schema is this complete.

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+resource ('Remove a purchase order link'), which is unambiguous against the many sibling delete_* tools that each name their own resource. It does not explicitly differentiate from delete_purchase_order or delete_purchase_order_line, but the resource noun does that work on its own.

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 name and the required write scope, so an agent can infer this is the targeted removal for a single link. There is no when-to-use/when-not guidance and no mention of list_purchase_order_links or get_purchase_order_link as the discovery step, nor of bulk alternatives.

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