freeze

You can restrict file edits to a specific directory by setting a boundary that blocks Edit and Write operations outside a designated path. A PreToolUse hook validates the file_path against your defined boundary before any action proceeds.

Yes, preventing accidental changes outside your project scope is done by freezing a directory for the session. This on-demand scoping isolates debugging or module-focused changes to a single folder so no unintended modifications occur elsewhere.

A PreToolUse hook enforces directory boundaries by comparing the requested file_path against a user-defined boundary stored in the session state. If the target path falls outside the allowed directory, the Edit or Write operation is denied immediately.

The best way to lock a single module for isolated code modifications is to interactively define a boundary at runtime. Once the directory path is set, all subsequent edits are confined strictly to that module, preventing cross-project interference.

No external dependencies are needed to set up edit boundaries in your workspace. The boundary enforcement operates entirely through the built-in PreToolUse hook mechanism, requiring only an interactive prompt to designate the target directory path.

Your file writes are being denied because the active boundary restricts operations to a single designated directory. When you attempt to edit files outside the frozen path, the hook intercepts and blocks the Write or Edit action to protect the broader workspace.
