Create new prose with Sepia's write operation.
Creates new prose by routing the request to Sepia's write operation.
When to use it
Use when the user explicitly requests Sepia write to create new prose.
Give it a request for new prose; it routes to Sepia's write operation and asks for a target if none was supplied.
Requires Sepia co-installed at the exact sibling path ../sepia/SKILL.md; stops if that file is absent or unreadable.
