+# /careful — Destructive Command Guardrails
+
+Safety mode is now **active**. Every bash command will be checked for destructive
+patterns before running. If a destructive command is detected, you'll be warned
+and can choose to proceed or cancel.
+
+```bash
+mkdir -p ~/.gstack/analytics
+echo '{"skill":"careful","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
+```
+
+## What's protected
+
+| Pattern | Example | Risk |
+|---------|---------|------|
+| `rm -rf` / `rm -r` / `rm --recursive` | `rm -rf /var/data` | Recursive delete |
+| `DROP TABLE` / `DROP DATABASE` | `DROP TABLE users;` | Data loss |
+| `TRUNCATE` | `TRUNCATE orders;` | Data loss |
+| `git push --force` / `-f` | `git push -f origin main` | History rewrite |
+| `git reset --hard` | `git reset --hard HEAD~3` | Uncommitted work loss |
+| `git checkout .` / `git restore .` | `git checkout .` | Uncommitted work loss |
+| `kubectl delete` | `kubectl delete pod` | Production impact |
+| `docker rm -f` / `docker system prune` | `docker system prune -a` | Container/image loss |
+
+## Safe exceptions
+
+These patterns are allowed without warning:
+- `rm -rf node_modules` / `.next` / `dist` / `__pycache__` / `.cache` / `build` / `.turbo` / `coverage`
+
+## How it works
+
+The hook reads the command from the tool input JSON, checks it against the
+patterns above, and returns `permissionDecision: "ask"` with a warning message
+if a match is found. You can always override the warning and proceed.
+
+To deactivate, end the conversation or start a new one. Hooks are session-scoped.

+# /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).
+
+```bash
+mkdir -p ~/.gstack/analytics
+echo '{"skill":"freeze","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
+```
+
+## Setup
+
+Ask the user which directory to restrict edits to. Use AskUserQuestion:
+
+- Question: "Which directory should I restrict edits to? Files outside this path will be blocked from editing."
+- Text input (not multiple choice) — the user types a path.
+
+Once the user provides a directory path:
+
+1. Resolve it to an absolute path:
+```bash
+FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
+echo "$FREEZE_DIR"
+```
+
+2. Ensure trailing slash and save to the freeze state file:
+```bash
+FREEZE_DIR="${FREEZE_DIR%/}/"
+STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}"
+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` or end the session."
+
+## How it works
+
+The hook reads `file_path` from the Edit/Write tool input JSON, then checks
+whether the path starts with the freeze directory. If not, it returns
+`permissionDecision: "deny"` to block the operation.
+
+The freeze boundary persists for the session via the state file. The hook
+script reads it on every Edit/Write invocation.
+
+## Notes
+
+- The trailing `/` on the freeze directory prevents `/src` from matching `/src-old`
+- Freeze applies to Edit and Write tools only — Read, Bash, Glob, Grep are unaffected
+- This prevents accidental edits, not a security boundary — Bash commands like `sed` can still modify files outside the boundary
+- To deactivate, run `/unfreeze` or end the conversation

+# /guard — Full Safety Mode
+
+Activates both destructive command warnings and directory-scoped edit restrictions.
+This is the combination of `/careful` + `/freeze` in a single command.
+
+**Dependency note:** This skill references hook scripts from the sibling `/careful`
+and `/freeze` skill directories. Both must be installed (they are installed together
+by the gstack setup script).
+
+```bash
+mkdir -p ~/.gstack/analytics
+echo '{"skill":"guard","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
+```
+
+## Setup
+
+Ask the user which directory to restrict edits to. Use AskUserQuestion:
+
+- Question: "Guard mode: which directory should edits be restricted to? Destructive command warnings are always on. Files outside the chosen path will be blocked from editing."
+- Text input (not multiple choice) — the user types a path.

+1. Resolve it to an absolute path:
+```bash

+STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}"
+mkdir -p "$STATE_DIR"
+echo "$FREEZE_DIR" > "$STATE_DIR/freeze-dir.txt"
+echo "Freeze boundary set: $FREEZE_DIR"
+```
+
+Tell the user:
+- "**Guard mode active.** Two protections are now running:"
+- "1. **Destructive command warnings** — rm -rf, DROP TABLE, force-push, etc. will warn before executing (you can override)"
+- "2. **Edit boundary** — file edits restricted to `<path>/`. Edits outside this directory are blocked."
+- "To remove the edit boundary, run `/unfreeze`. To deactivate everything, end the session."
