Restricts Claude's Edit and Write operations to a single directory for the duration of a session. Any attempt to modify files outside the allowed path is blocked outright. Useful when debugging or making targeted changes where touching unrelated code would be a problem.
Rather than relying on discipline or post-hoc diffs to catch stray edits, it enforces a hard boundary at the tool level so out-of-scope writes never happen in the first place.
When to use it
- Scoping a refactor to one module without risking changes to shared utilities
- Debugging a specific package while keeping the rest of the codebase untouched
- Reviewing a PR's changed directory without accidentally editing unrelated files
- Onboarding to a codebase by limiting writes to a sandbox folder
- Isolating config changes to a single service directory during incident response
