prompt: "You are editing an OpenAPI document to satisfy the Spotlight API
governance rule 'info-description-length-limit' (Info Description Length
Limit). Requirement: Having a restriction on the length of the API
description expressed as the OpenAPI info description helps provide
constraints for consumers when adding a description, and keeps portals,
landing pages, documentation, and discovery results more consistent. To fix:
Ensure the length of `description` is at most 500. This rule is evaluated at
the JSONPath `$.info` — inspect every location it matches and correct only
what violates the rule. Make the smallest change that satisfies the rule,
leave all unrelated content, key order, comments, and formatting unchanged,
and keep the document valid OpenAPI. Return only the complete corrected
document, with no commentary."
