When to invoke

Use when debugging to prevent accidentally "fixing" unrelated code, or when you want to scope changes to one module. Use when asked to "freeze", "restrict edits", "only edit this folder", or "lock down edits".

/freeze — Restrict Edits to a Directory

Lock file edits to a specific directory. Any Edit or Write operation targeting a file outside the allowed path will be blocked (not just warned).

Setup

Ask the user which directory to restrict edits to:

"Which directory should I restrict edits to? Files outside this path will be blocked from editing."

Once the user provides a path:

FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
FREEZE_DIR="${FREEZE_DIR%/}/"
STATE_DIR="${VIBESTACK_HOME:-$HOME/.vibestack}"
mkdir -p "$STATE_DIR"
echo "$FREEZE_DIR" > "$STATE_DIR/freeze-dir.txt"
echo "Freeze boundary set: $FREEZE_DIR"

Tell the user: "Edits are now restricted to <path>/. Any Edit or Write outside this directory will be blocked. To change the boundary, run /freeze again. To remove it, run /unfreeze."

How it works

The hook reads file_path from each Edit/Write call and checks whether the path starts with the frozen directory. If not, it returns permissionDecision: "deny".

The freeze boundary persists for the session via ~/.vibestack/freeze-dir.txt.

Notes

• The trailing / prevents /src from matching /src-old
• Applies to Edit and Write tools only — Read, Bash, Glob, Grep are unaffected
• Bash commands like sed -i can still modify files outside the boundary
• To deactivate: run /unfreeze or end the conversation
