Order paid TLS certificate

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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description adds context the annotations cannot: the order may become non-refundable once submitted/issued, it requires certificates:order plus paid-operation spend controls, the request must be unchanged with the same idempotencyKey and short-lived quote token, and the private key never leaves the customer. These are exactly the extra behavioral facts an agent needs before spending money.

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?

Purpose and the user-approval gate are front-loaded across five tight sentences, each carrying a distinct obligation (prerequisite, approval, unchanged request, key custody, refundability, permissions). It is dense but nothing is filler; only the permissions sentence could be seen as stacked-on detail.

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, monetary, 14-parameter tool with no output schema, the description covers preconditions, permissions, idempotency, and irreversibility well. The one gap is what the call returns (e.g., a new order UUID) and any follow-up step for validation or download, which the agent must infer.

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%, so the baseline is 3, but the description adds cross-call semantics the schema cannot: the request must be byte-identical to the quote, the idempotencyKey must be the same one used for quote_certificate, and the quote_token is exact and short-lived. It does not, however, walk through the acknowledge_exact_quote_and_payment or contact-ID fields.

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 opens with a specific verb+resource pair: confirm and pay for the exact quote from quote_certificate. It distinguishes itself cleanly from the sibling quote_certificate (which only quotes) and from order_automatic_ssl_subscription/order_automatic_ssl_domain by being the paid, quote-backed TLS order path.

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?

It states the exact precondition ('Call only after the user explicitly approves the exact final EUR total, certificate names, term, validation level, and payment method') and names the prerequisite tool (quote_certificate), so the agent knows when this tool is appropriate versus when to go back and quote first. Exclusion and ordering are both explicit.

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