## Preamble (run first)

```bash
# === RKstack Preamble (guard) ===

# Read detection cache (written by session-start via rkstack detect)
if [ -f .rkstack/settings.json ]; then
  cat .rkstack/settings.json
else
  echo "WARNING: .rkstack/settings.json not found — detection cache missing"
fi

# Session-volatile checks (can change mid-session)
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
_HAS_CLAUDE_MD=$([ -f CLAUDE.md ] && echo "yes" || echo "no")
echo "BRANCH: $_BRANCH"
echo "CLAUDE_MD: $_HAS_CLAUDE_MD"
```

Use the detection cache and preamble output to adapt your behavior:
- **TypeScript/JavaScript** — see `detection.flowType` (web or default). If web: check React/Vue/Svelte patterns, responsive design, component architecture. If default: CLI tools, MCP servers, backend scripts.
- **Python** — backend/ML/scripts. Check PEP8 conventions, pytest for testing.
- **Go** — backend/infra. Check error handling patterns, go test.
- **Rust** — systems. Check ownership patterns, cargo test.
- **Java/C#** — enterprise. Check build tool (Maven/Gradle/.NET), framework conventions.
- **Ruby** — web/scripting. Check Gemfile, Rails conventions if present.
- **Terraform/HCL** — infrastructure as code. Plan before apply, extra caution with state.
- **Ansible** — configuration management. Check inventory, role conventions, vault usage.
- **Docker/Compose** — containerized. Check service dependencies, .env patterns.
- **justfile** — task runner present. Use `just` commands instead of raw shell.
- **mise** — tool version manager. Versions are pinned — don't suggest global installs.
- **CLAUDE.md exists** — read it for project-specific commands and conventions.
- Read `detection.stack` for what's in the project and `detection.stats` for scale (files, code, complexity).
- Read `detection.repoMode` for solo vs collaborative.
- Read `detection.services` for Supabase and other service integrations.

## Completion Status

When completing a skill workflow, report status using one of:
- **DONE** — All steps completed successfully. Evidence provided for each claim.
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.

### Escalation

It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."

Bad work is worse than no work. You will not be penalized for escalating.
- If you have attempted a task 3 times without success, STOP and escalate.
- If you are uncertain about a security-sensitive change, STOP and escalate.
- If the scope of work exceeds what you can verify, STOP and escalate.

Escalation format:
```
STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]
```

# /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 part of the
rkstack plugin).

## 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.

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:-$HOME/.rkstack}"
mkdir -p "$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."

## What's protected

See `/careful` for the full list of destructive command patterns and safe exceptions.
See `/freeze` for how edit boundary enforcement works.
