What problem does it solve? When debugging or working in a large codebase, it is easy for an AI assistant to accidentally modify files outside the intended scope. This Skill enforces a hard boundary so Edit and Write operations outside a chosen directory are blocked, not just warned about. ## Core Features & Use Cases - Directory-scoped edit enforcement: A PreToolUse hook intercepts every Edit and Write call and denies any operation targeting a file outside the frozen directory. - Fail-closed design: Unparseable tool payloads, missing helpers, or unexpected hook failures all result in a deny decision, so the boundary never silently fails open. - Symlink-aware path resolution: Paths are resolved through their final component, so an in-boundary symlink pointing outside the boundary is checked against its real target. - Use Case: While debugging a bug in the src/auth module, freeze edits to that directory so the assistant cannot accidentally "fix" unrelated code elsewhere in the repository. ## Quick Start Ask the assistant to freeze edits to the directory you are working in, for example by saying "freeze edits to src/auth so nothing outside it can be modified".
