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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered structurally. The description adds a genuine behavioral fact not in the structured data: the caller must hold the infrastructure_asset_parts:write scope. It stops short of noting side effects or reversibility, which is acceptable given the annotation coverage.

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 tight sentences: the action first, the prerequisite second. Nothing is padded or restated 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 single-parameter delete with no output schema, the definition plus annotations give an agent everything needed to invoke it: what it removes, that it is destructive but idempotent, and the required scope. Only the sibling-disambiguation angle is missing.

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 coverage is 100% and the single 'id' parameter is already documented as a UUID 'Association ID'. The phrase 'by ID' adds no meaning beyond the schema, so the baseline 3 for a fully documented schema 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) plus a precise resource: 'infrastructure asset part association', which usefully clarifies that this removes the link rather than the part itself. It does not, however, name or distinguish itself from the many look-alike delete_* siblings an agent must choose between.

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 or when-not-to-use guidance. An agent gets no signal about how this differs from delete_infrastructure_asset, delete_part, or update_infrastructure_asset_part as an alternative action on the same association.

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