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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds only the returned field surface (description, attachments, processing status); it says nothing about behavior when the ID is unknown or stale, so with annotations doing the heavy lifting a 3 is right.

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?

One front-loaded sentence with no filler; the verb and resource lead and the field enumeration follows. It is efficient, though the field list is the only content and the sentence does little more than that.

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?

No output schema exists, so the description usefully names the returned content, and for a single-ID getter that is close to sufficient. It omits error/not-found behavior and any note on related tools, keeping it short of fully complete.

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 100% schema description coverage and a single 'id' parameter documented as 'Work request ID' with a UUID pattern, the schema fully carries the parameter burden. The description adds no format, sourcing, or lookup guidance beyond it, so the 3 baseline 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 states a specific verb and resource ('Get detailed work request information') and enumerates the payload (description, attachments, processing status), which separates it from create/update/delete_work_request. It does not explicitly distinguish itself from the sibling list_work_requests, so it stops short of the 5 bar.

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 only implied: 'detailed work request information' plus a required UUID id signals a single-record lookup versus the list tool, but there is no explicit when-to-use, when-not-to-use, or named alternative. Adequate but with a clear gap.

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