Ready up Jira tickets for refinement, including brand-new not-yet-keyed backlog items, by gathering context from linked incidents or interviewing the user when no incident exists, populating a YAML template against the project's 'ready for refinement' standard, validating it against a JSON schema plus gap-detection heuristics for testability and vagueness, and generating a structured markdown document. Use when asked to ready up, prepare for refinement, draft a new backlog ticket, or write up a specific ticket key.
