x-cli-name
`x-cli-name` appears on operations. Its value is a string. Used by a single provider across 20 OpenAPI documents. Observed values include `subscriptions:apm-list`, `accounts:find`, `accounts:application-mark-recent`, `accounts:application-star`. Consistent with cli — this is inferred from where the key appears and what it carries, not from any published definition.

Why this is not in OpenAPI
Extensions exist because a provider needed something the specification would not carry. Most of what they hold is not the API contract at all — it is operational metadata about the contract: documentation, lifecycle, policy, provenance, and now agents. That metadata is usually better placed alongside the contract, in an Overlay or an APIs.json index, than crammed inside it. See everything else doing the cli job.
