Internal skill — normally invoked by backbone-tasks, not directly. Writes and optionally creates full-scope Jira stories in the Backbone (BB) project for larger development work — new reports, features spanning multiple pages, multi-persona workflows, or anything derived from a PRD or detailed requirements. Uses the 6-section story template and auto-generates BE + FE subtasks. Prefer routing through backbone-tasks unless the user explicitly invokes this skill by name (e.g., '/backbone-tasks-full-story'). Do NOT trigger on small dev work — use backbone-tasks-light-story for those. Do NOT trigger on bug reports — use backbone-tasks-bugs for those.
