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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the description does not need to restate safety. It adds domain semantics (the pickup location and the printed/cut readiness condition) but says nothing about the identity/verification gate or the need_verification response path, which are behavioural traits an agent should anticipate.

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?

A single 22-word sentence with the readiness condition front-loaded and zero filler. Every clause earns its place.

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 read-only status tool with no output schema, the description conveys what state is being reported and at which stage. It leaves the return shape and the verification/6-digit-code path to the schema property descriptions, which do cover them, so the definition is largely but not entirely self-sufficient.

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 100% and every property (token, order_id, order_name, line_item_id, customer_email) is documented in-schema, including the token/email verification flow. The description adds no parameter-level detail, so the baseline 3 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 check: whether an order or line items is ready for pickup at Derrimut VIC, and pins down what 'ready' means (printed and cut, before dispatch). That is a clear verb+resource with scope, but it never names or contrasts with the adjacent status siblings (vivid_fulfilment_order_status, vivid_fulfilment_production_stage, vivid_fulfilment_shipping), so an agent has to infer which status tool to reach for.

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: 'before dispatch' hints this is the pre-shipping stage answer, but there is no explicit when-to-use, when-not, or alternative named. With four sibling status/fulfilment tools available, the absence of routing guidance is a real gap, though the pickup-specific framing does narrow intent.

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