Quote Automatic SSL subscription

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

Goes well beyond the annotations (which only say not-read-only, idempotent, non-destructive) by disclosing the quote is short-lived, that nothing is charged, the required 'certificates:order' scope, paid-operation/spend-cap dependence, and that the idempotencyKey is reused verbatim for confirmation. This is precisely the operational context an agent needs before invoking.

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 'no charge' distinction are front-loaded, and the sentences are individually tight. It is somewhat long and mixes identity semantics (apex/wildcard), pricing advice, and permission requirements, but nothing is pure filler.

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?

With no output schema and six required parameters, the description carries the burden well, covering the quote lifecycle, permission/idempotency prerequisites, and the pre-order pricing disclosure. The only gap is return-value specifics beyond 'short-lived', which is acceptable given no output schema is provided.

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 coverage is already 100%, so the baseline is 3, but the description adds a constraint absent from the schema: the product must be an 'acme_subscription catalog product' with its 'exact current EUR offer generation'. The www-alias/apex/wildcard note duplicates the schema's own domains description, so the gain is incremental rather than comprehensive.

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?

States a specific verb+resource ('Create a short-lived exact quote for Automatic SSL') and immediately distinguishes itself from the ordering sibling by noting 'without charging'. An agent can tell this apart from order_automatic_ssl_subscription without opening either schema.

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?

Gives clear usage context: use an acme_subscription catalog product, exact current offer generation, and disclose the VAT-inclusive total 'before ordering', implying the quote-then-order workflow. It does not, however, name the alternative quote tools (quote_automatic_ssl_domain, quote_automatic_ssl_renewal) or state when-not to use this one, so it stops short of full routing guidance.

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