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 structurally. The description still adds two items beyond that: the required infrastructure_asset_parts:write scope and the fact that it removes the association rather than the part itself. It does not cover not-found behavior or error semantics, keeping it short of a 5.

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 sentences, zero filler, with the operation front-loaded before the prerequisite scope. Every clause carries information.

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 single-parameter delete with annotations covering destructiveness and idempotency and no output schema, the description supplies what an agent needs: the target, the key, and the required permission. It omits failure/not-found behavior and confirmation of whether deletion is recoverable, which is a minor 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?

Schema description coverage is 100% and the single 'id' parameter is documented as 'Association ID' with uuid format. The description's 'by ID' adds nothing beyond the schema, so the baseline 3 for fully-covered schemas 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 (Delete) and a precise resource (an infrastructure asset part association), plus the keying mechanism (by ID). The domain-specific naming inherently separates it from delete_asset_part and delete_part, but the description never explicitly names a sibling, so it lands just short of a 5.

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?

No when-to-use guidance, no exclusions, and no pointer to alternatives such as update_infrastructure_asset_part (to edit the association) or delete_infrastructure_asset (to remove the whole asset). The agent must infer usage purely from the name.

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