What problem does it solve? When debugging or working in a large codebase, AI-assisted edits can accidentally touch unrelated files, causing unintended side effects. This Skill restricts all Edit and Write operations to a single directory you choose, so changes stay scoped to the module you are working on. ## Core Features & Use Cases - Edit Boundary Enforcement: A PreToolUse hook inspects every Edit/Write call and denies any operation targeting a file outside the frozen directory. - Session-Persistent State: The freeze boundary is stored in a state file and persists for the entire session until explicitly removed. - Path Safety: Trailing-slash normalization prevents sibling directories like /src-old from matching a /src boundary, and symlink/relative path resolution stops bypass attempts. - Use Case: While debugging a payment module, freeze edits to src/payments/ so the assistant cannot accidentally "fix" unrelated code in other parts of the repository. ## Quick Start Ask the assistant to freeze edits to a specific directory, for example: restrict all edits to the src/payments folder for this session.
