feat: generated Factory Droid skill output (.factory/skills/)

29 skills generated for Factory Droid with:
- user-invocable: true on all skills
- disable-model-invocation: true on 6 sensitive skills
- .factory/skills/ paths (no .claude/skills/ references)
- $GSTACK_ROOT env vars for runtime root detection
- Tool name translation (Claude tool names → generic phrasing)

Committed to git for CI freshness checks and direct consumption.

+  Safety guardrails for destructive commands. Warns before rm -rf, DROP TABLE,
+  force-push, git reset --hard, kubectl delete, and similar destructive operations.
+  User can override each warning. Use when touching prod, debugging live systems,
+  or working in a shared environment. Use when asked to "be careful", "safety mode",
+  "prod mode", or "careful mode".

+> **Safety Advisory:** This skill includes safety checks that check bash commands for destructive operations (rm -rf, DROP TABLE, force-push, git reset --hard, etc.) before execution. When using this skill, always pause and verify before executing potentially destructive operations. If uncertain about a command's safety, ask the user for confirmation before proceeding.
+
+
+# /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.
