approveOrder

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

Annotations already indicate readOnlyHint=false, and the description confirms a mutating action. However, it adds no further behavioral context such as success/failure outcomes, idempotency, or permission requirements. Without annotations, the description would be insufficient.

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 extremely concise with two sentences, the first stating the purpose and the second providing a useful hint. No redundant information.

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 simple approval tool, the description covers the basics. However, it lacks any mention of return values or side effects, and the sibling submitOrderApproval might require differentiation. Given no output schema, more detail could help.

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?

The schema already describes all parameters with 100% coverage. The description adds only a single hint about the source of workflow_instance_id. Since baseline is 3 for high coverage, this is adequate but not additive.

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 clearly states the tool approves or rejects an order in DMS, specifying the action and resource. It does not explicitly differentiate from the sibling tool 'submitOrderApproval', but the purpose is specific and unambiguous.

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 description provides a useful hint that workflow_instance_id comes from getOrderInfo, guiding usage. However, it offers no guidance on when to prefer this tool over alternatives like submitOrderApproval, and does not mention any conditions or prerequisites.

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