概要
The Context Synchronization skill solves the problem of documentation rot by ensuring high-level project files stay aligned with the actual state of the codebase. When a development track is completed, this skill analyzes the changes to determine if updates are required for the product description, technology stack, or core guidelines. It provides an interactive workflow where users review proposed diffs before changes are applied and committed to the repository, maintaining a reliable single source of truth for the entire project context.
