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

With no annotations, the description carries the full disclosure burden, and it does deliver one critical fact: the tool never charges a card itself and defers approval to a human. Beyond that it is silent on side effects that matter for an order-creating tool, including whether orders persist, how long the payment link stays valid, and whether repeated calls create duplicate orders.

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?

Two short sentences, both front-loaded with the critical constraint (payment link for human approval) sitting alongside the core action. Nothing is redundant or padded.

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?

Given 0% schema coverage, a nested buyer object, and no output schema, the description is too thin for the tool's complexity: it never touches parameters, error/failure behavior, or what the returned link looks like. The human-approval guarantee is the only substantive behavioral coverage.

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%, so the description must compensate, and it does not: product_id, qty, and the nested buyer object (email, country) are never mentioned or explained. With a nested object and a default-behavior qty, the absence of any semantic guidance is a meaningful 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 uses a specific verb+resource ("Create an order") and adds the outcome ("get a payment link"), so an agent knows exactly what the call produces. It does not, however, differentiate itself from the closely related siblings quote_order and buy_by_answer, which an agent could plausibly confuse with it.

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 phrase "for the human to approve" implies the intended flow: use this when a human must confirm payment before anything is charged. That is useful implied guidance, but there are no explicit when-to-use/when-not rules and no naming of alternatives such as quote_order (for pricing) or buy_by_answer (for direct purchase).

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