What this skill does

# SafeExec - Safe Command Execution

Provides secure command execution capabilities for OpenClaw Agents with automatic interception of dangerous operations and approval workflow.

## Features

- 🔍 **Automatic danger pattern detection** - Identifies risky commands before execution
- 🚨 **Risk-based interception** - Multi-level assessment (CRITICAL/HIGH/MEDIUM/LOW)
- 💬 **In-session notifications** - Real-time alerts in your current terminal/session
- ✅ **User approval workflow** - Commands wait for explicit confirmation
- 📊 **Complete audit logging** - Full traceability of all operations
- 🤖 **Agent-friendly** - Non-interactive mode support for automated workflows
- 🔧 **Platform-agnostic** - Works independently of communication tools (Feishu, Telegram, etc.)

## Quick Start

### Installation (One Command)

**The easiest way to install SafeExec:**

Just say in your OpenClaw chat:
```
Help me install SafeExec skill from ClawdHub
```

OpenClaw will automatically download, install, and configure SafeExec for you!

### Alternative: Manual Installation

If you prefer manual installation:

```bash
# Using ClawdHub CLI
export CLAWDHUB_REGISTRY=https://www.clawhub.ai
clawdhub install safe-exec

# Or download directly from GitHub
git clone https://github.com/OTTTTTO/safe-exec.git ~/.openclaw/skills/safe-exec
chmod +x ~/.openclaw/skills/safe-exec/safe-exec*.sh
```

### Enable SafeExec

After installation, simply say:
```
Enable SafeExec
```

SafeExec will start monitoring all shell commands automatically!

## How It Works

Once enabled, SafeExec automatically monitors all shell command executions. When a potentially dangerous command is detected, it intercepts the execution and requests your approval through **in-session terminal notifications**.

**Architecture:**
- Requests stored in: `~/.openclaw/safe-exec/pending/`
- Audit log: `~/.openclaw/safe-exec-audit.log`
- Rules config: `~/.openclaw/safe-exec-rules.json`

## Usage

**Enable SafeExec:**
```
Enable SafeExec
```

```
Turn on SafeExec
```

```
Start SafeExec
```

Once enabled, SafeExec runs transparently in the background. Agents can execute commands normally, and SafeExec will automatically intercept dangerous operations:

```
Delete all files in /tmp/test
```

```
Format the USB drive
```

SafeExec detects the risk level and displays an in-session prompt for approval.

## Risk Levels

**CRITICAL**: System-destructive commands (rm -rf /, dd, mkfs, etc.)
**HIGH**: User data deletion or significant system changes
**MEDIUM**: Service operations or configuration changes
**LOW**: Read operations and safe file manipulations

## Approval Workflow

1. Agent executes a command
2. SafeExec analyzes the risk level
3. **In-session notification displayed** in your terminal
4. Approve or reject via:
   - Terminal: `safe-exec-approve <request_id>`
   - List pending: `safe-exec-list`
   - Reject: `safe-exec-reject <request_id>`
5. Command executes or is cancelled

**Example notification:**
```
🚨 **Dangerous Operation Detected - Command Intercepted**

**Risk Level:** CRITICAL
**Command:** `rm -rf /tmp/test`
**Reason:** Recursive deletion with force flag

**Request ID:** `req_1769938492_9730`

ℹ️  This command requires user approval to execute.

**Approval Methods:**
1. In terminal: `safe-exec-approve req_1769938492_9730`
2. Or: `safe-exec-list` to view all pending requests

**Rejection Method:**
 `safe-exec-reject req_1769938492_9730`
```

## Configuration

Environment variables for customization:

- `SAFE_EXEC_DISABLE` - Set to '1' to globally disable safe-exec
- `OPENCLAW_AGENT_CALL` - Automatically enabled in agent mode (non-interactive)
- `SAFE_EXEC_AUTO_CONFIRM` - Auto-approve LOW/MEDIUM risk commands

## Examples

**Enable SafeExec:**
```
Enable SafeExec
```

**After enabling, agents work normally:**
```
Delete old log files from /var/log
```

SafeExec automatically detects this is HIGH risk (deletion) and displays an in-session approval prompt.

**Safe operations pass through without interruption:**
```
List files in /home/user/documents
```

This is LOW risk and executes without approval.

## Global Control

**Check status:**
```
safe-exec-list
```

**View audit log:**
```bash
cat ~/.openclaw/safe-exec-audit.log
```

**Disable SafeExec globally:**
```
Disable SafeExec
```

Or set environment variable:
```bash
export SAFE_EXEC_DISABLE=1
```

## Reporting Issues

**Found a bug? Have a feature request?**

Please report issues at:
🔗 **https://github.com/OTTTTTO/safe-exec/issues**

We welcome community feedback, bug reports, and feature suggestions!

When reporting issues, please include:
- SafeExec version (run: `grep "VERSION" ~/.openclaw/skills/safe-exec/safe-exec.sh`)
- OpenClaw version
- Steps to reproduce
- Expected vs actual behavior
- Relevant logs from `~/.openclaw/safe-exec-audit.log`

## Audit Log

All command executions are logged with:
- Timestamp
- Command executed
- Risk level
- Approval status
- Execution result
- Request ID for traceability

Log location: `~/.openclaw/safe-exec-audit.log`

## Integration

SafeExec integrates seamlessly with OpenClaw agents. Once enabled, it works transparently without requiring changes to agent behavior or command structure. The approval workflow is entirely local and independent of any external communication platform.

## Platform Independence

SafeExec operates at the **session level**, working with any communication channel your OpenClaw instance supports (webchat, Feishu, Telegram, Discord, etc.). The approval workflow happens through your terminal, ensuring you maintain control regardless of how you're interacting with your agent.
