freeze

To restrict file edits to a specific directory during debugging, you establish a freeze boundary that validates all modification requests against an approved path. This enforces edit boundaries by blocking any out-of-scope Write operations.

Directory boundary enforcement for workflow safety is a mechanism that stores a persistent path scope and denies file modifications outside that target. It prevents unintended edits by validating every applicable request against the approved directory.

You prevent unintended modifications to unrelated files by applying session scoping to your target module. This ensures focused development by denying out-of-scope file changes while still allowing permitted operations within the approved boundary.

Yes, Claude Code supports edit restriction for isolated module development through validation hooks that intercept file modification operations. These hooks check against a stored freeze boundary to deny any out-of-scope file changes.

A limitation of using a freeze boundary for file scope control is that it requires persistent boundary state handling and validation hooks to function correctly. It strictly denies out-of-scope edits, meaning any cross-directory refactoring will be blocked.

You need to apply an edit boundary when debugging a single component within a large codebase or working on isolated modules. This ensures that only that component's files can be changed while unrelated areas remain completely protected.
