What problem does it solve? Long book editing sessions with AI assistants lose track of which draft is current, what was edited last, and what to do next. This Skill provides structured project management with automatic checkpointing, backup tracking, and keyword search so editing state is never lost across sessions. ## Core Features & Use Cases - Project Initialization: Creates a standardized directory structure (current draft, backups, checkpoints, notes) for any book project, optionally importing an existing manuscript. - Session Management: Start and end editing sessions with automatic backups, word count tracking, and checkpoint summaries that record what was done and what comes next. - Content Search & Chapter Detection: Search the manuscript for keywords with surrounding context, or list all detected chapter headings with line numbers. - Backup & Restore: List timestamped backups and restore any version, with the current draft automatically preserved before restoring. - Use Case: An author editing a 90,000-word novel across many sessions runs a session-start command to see the last checkpoint and priority, edits the manuscript, then ends the session with a summary so the next session resumes exactly where it left off. ## Quick Start Initialize a book project with my manuscript file, then start an editing session and show me the current word count and last checkpoint.
