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

Annotations already declare this as destructive and non-idempotent, but the description adds critical behavioral context: no change occurs until a human approves the exact request and execute_approved_action is called, and organization-configurable MCP approvals plus business workflow approvals always apply. It stops short of describing irreversibility or failure behavior, but it substantially exceeds 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?

The description is appropriately sized and contains no irrelevant filler; the approval workflow sentences earn their place. Its first sentence is generic context before the specific action, so it is slightly less front-loaded than ideal, but the overall structure is efficient.

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 destructive mutation tool with an output schema, the description does a good job covering the delayed-approval execution model. However, it leaves parameter semantics unaddressed despite 0% schema description coverage, which is a meaningful gap for an agent that must supply exactly the correct two identifiers.

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 0% for both required UUID parameters, and the description does not explain changeRequestId versus changeRequestLineItemId. The phrase "financial change-request line item" hints at the resource, but an agent still must infer that two distinct identifiers are required and what each one represents.

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: "Remove a financial change-request line item." This distinguishes the tool from siblings like delete_change_request and delete_change_request_document by making clear it operates on a line item within a change request, not the parent record or attached document.

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?

The opening sentence gives broad context ("working with RetailHardHat change_requests records") but does not explicitly say when to use this instead of update_change_request_line_item, delete_change_request, or delete_change_request_document. The approval workflow details indicate prerequisites, but the selection guidance is only implied by the verb and resource.

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