What problem does it solve? Keeping a vault-wide improvement backlog consistent is tedious: index entries drift from task files, completed tasks pile up, and duplicates accumulate. This Skill maintains the improvements/ directory so the backlog index and task files stay synchronized and clean. ## Core Features & Use Cases - Backlog and Task Management: Add new improvement ideas as kebab-case task files under improvements/tasks/ and register them in the improvements/backlog.md index with status, priority, and a one-line summary. - Update and Deduplication: Update existing tasks, adjust priority (高/中/低) and status (未着手/進行中/保留), and merge overlapping tasks instead of creating duplicates. - Completion Hygiene: Remove completed tasks from both the backlog and tasks directory, migrate durable decisions to README or reference docs, and verify no broken links remain. - Use Case: When you notice a recurring vault workflow problem, ask the assistant to register it as a new improvement task; it will check for duplicates, create the task file, and add a properly formatted index row. ## Quick Start Use the manage-vault-improvements skill to add a new improvement task about standardizing note templates to the backlog.
