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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description's only extra behavioral note is the approval-requirement boilerplate, which is arguably irrelevant for a read-only list operation and adds little actionable context.

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?

The description is short and the usage cue is front-loaded. The final sentence about configurable MCP approvals is boilerplate filler that doesn't earn its place for a read-only list tool, slightly diluting otherwise efficient prose.

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?

Complexity is low (single param) and an output schema exists so return values needn't be explained. However, the description omits mention of the required changeRequestId input and pagination/scope behavior, leaving gaps an agent must fill from the schema alone.

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?

There is one required parameter (changeRequestId) and schema description coverage is 0%, but the description never mentions it, its UUID format, or that it scopes the listing to a single change request. The required ID is only weakly inferable from the tool name, so the description fails to compensate for the coverage gap.

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 ('Read') and resource ('change-request line-items') and anchors it to the RetailHardHat change_requests context. It is clear what the tool does, though it doesn't explicitly distinguish itself from siblings like list_change_requests or get_change_request beyond the resource name itself.

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?

'Use this when working with RetailHardHat change_requests records' implies a use context but gives no when-not guidance or alternatives (e.g., versus list_change_request_documents or get_change_request). Usage is only inferable from the tool name and resource.

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