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

The description goes well beyond the annotations by disclosing the two-step approval workflow: 'Returns an AurasPay approval URL first' and 'No change occurs until separate human approval.' It also explains idempotent result retrieval by saying to reuse the identical requestId and details, enriching the idempotentHint annotation with concrete retrieval behavior.

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?

Three front-loaded sentences cover purpose, the approval URL behavior, and the idempotent reuse pattern with no filler. Every sentence adds operationally relevant 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 mutating, approval-gated operation, the description covers the core workflow and idempotency semantics, and an output schema exists to describe the return shape. It is slightly incomplete only in directly mapping the requestId/details parameters to their roles in the schema.

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?

Input schema has 0% description coverage, and the description does not formally explain details.id or details.status, though 'Close or reopen' implies status mapping and the ticket phrase implies id. It does add useful meaning by stating that requestId and details must be reused identically to retrieve the result, but the two required parameters are only minimally compensated.

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 opening clause 'Close or reopen one owned support ticket' names a specific verb, resource, and scope, making the operation immediately identifiable. It also distinguishes this from sibling ticket tools such as ticket_create, ticket_get, and ticket_reply by focusing exclusively on status mutation of an owned ticket.

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 establishes the clear usage context: this tool is for closing or reopening a ticket the caller owns. It does not explicitly name alternative tools or state when not to use it, but the 'owned' restriction and the close/reopen action provide enough context for an agent to select it among the ticket siblings.

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