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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds only that the record is a single "part association," and says nothing about behavior on a missing/invalid ID, permissions, or auth requirements.

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?

A single front-loaded sentence with no filler; the operation and its scoping are conveyed in the fewest words possible.

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 read tool with full schema coverage, annotations carrying the safety profile, and no output schema, the description covers the essentials. It lacks only edge-case behavior (e.g., not-found handling), which is a minor omission.

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 required parameter (id, uuid) is fully documented in the schema. The description's "by ID" restates the schema rather than adding format, constraint, or source-of-ID detail, so 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?

The description names a specific verb (Get) and resource (infrastructure asset part association) scoped to a single record by ID, which distinguishes it from the list_* and create/delete/update siblings. It stops short of explicitly contrasting itself with get_asset_part or list_infrastructure_asset_parts, so sibling differentiation is only implicit.

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?

"by ID" implicitly signals the usage condition (you already hold the identifier) versus the list_* variants, but the description never states when to prefer this tool or what to use when you only have a parent asset. Nothing is misleading, but guidance is inferred rather than stated.

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