What This Skill Does
Intercepts shell commands executed by OpenClaw agents, automatically detects dangerous patterns (e.g., rm -rf, dd, fork bombs), assigns a risk level (CRITICAL/HIGH/MEDIUM/LOW), and requires user approval before execution. Supports both interactive approval workflows and non-interactive agent mode with full audit logging.
Replaces manual oversight of risky shell commands by automating danger detection, risk assessment, and approval workflows with a complete audit trail.
When to Use It
- Prevent accidental deletion of system files by intercepting rm -rf commands
- Require human approval before running disk-wiping operations like dd
- Audit all shell commands executed by an agent during automated workflows
- Block fork bombs or resource-exhausting commands from being run without confirmation
- Approve or deny pending dangerous commands from a central request queue
- Enable safe non-interactive agent automation while logging all risky operations for review
Install
$ openclaw skills install @ottttto/safe-execSafeExec - Safe Command Execution
Provides secure command execution capabilities for OpenClaw Agents with automatic interception of dangerous operations and approval workflow.
Features
- ๐ Automatic danger pattern detection - Identifies risky commands before execution
- ๐จ Risk-based interception - Multi-level assessment (CRITICAL/HIGH/MEDIUM/LOW)
- ๐ฌ In-session notifications - Real-time alerts in your current terminal/session
- โ User approval workflow - Commands wait for explicit confirmation
- ๐ Complete audit logging - Full traceability of all operations
- ๐ค Agent-friendly - Non-interactive mode support for automated workflows
- ๐ง Platform-agnostic - Works independently of communication tools (webchat, Feishu, Telegram, etc.)
- ๐ Security-focused - No monitoring, no external notifications, no network calls
Agent Mode
When called by OpenClaw agents in non-interactive environments:
- Automatic bypass of confirmation prompts - Prevents agent hanging
- Full audit logging - All executions recorded with mode label (agent_auto vs user_approved)
- Safety preserved - Danger pattern detection and risk assessment remain active
- Intended use case - Automated workflows with human oversight via audit logs
Environment variables:
OPENCLAW_AGENT_CALL- Set by OpenClaw when agent executes commandsSAFE_EXEC_AUTO_CONFIRM- Manual override to auto-approve LOW/MEDIUM risk commands
Security Note: Agent mode does not disable safety checks. CRITICAL and HIGH risk commands are still intercepted, logged, and can be reviewed in audit trail.
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:
# Clone from GitHub
git clone https://github.com/OTTTTTO/safe-exec.git ~/.openclaw/skills/safe-exec
# Make scripts executable
chmod +x ~/.openclaw/skills/safe-exec/safe-exec*.sh
# Create symlinks to PATH (optional)
ln -s ~/.openclaw/skills/safe-exec/safe-exec.sh ~/.local/bin/safe-exec
ln -s ~/.openclaw/skills/safe-exec/safe-exec-*.sh ~/.local/bin/
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 - No external network calls
- No background monitoring processes
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, fork bombs) HIGH: User data deletion or significant system changes (chmod 777, curl | bash) MEDIUM: Service operations or configuration changes (sudo, firewall modifications) LOW: Read operations and safe file manipulations
Approval Workflow
- Agent executes a command
- SafeExec analyzes the risk level
- In-session notification displayed in your terminal
- Approve or reject via:
- Terminal:
safe-exec-approve <request_id> - List pending:
safe-exec-list - Reject:
safe-exec-reject <request_id>
- Terminal:
- Command executes or is cancelled
Example notification:
๐จ **Dangerous Operation Detected - Command Intercepted**
**Risk Level:** CRITICAL
**Command:** `rm -rf /tmp/test`
**Reason:** Recursive deletion with force flag
**Request ID:** `req_1769938492_9730`
โน๏ธ 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-execOPENCLAW_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:
cat ~/.openclaw/safe-exec-audit.log
Disable SafeExec globally:
Disable SafeExec
Or set environment variable:
export SAFE_EXEC_DISABLE=1
Reporting Issues
Found a bug? Have a feature request?
Please report issues at: ๐ 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
- Execution mode (user_approved / agent_auto)
- Approval status
- Execution result
- Request ID for traceability
Log location: ~/.openclaw/safe-exec-audit.log
Security & Privacy
What SafeExec does:
- โ Intercepts shell commands before execution
- โ Detects dangerous patterns using regex matching
- โ Requests user approval for risky commands
- โ Logs all executions to local audit file
- โ Works entirely locally on your machine
What SafeExec does NOT do:
- โ No monitoring of chat sessions or conversation history
- โ No reading of OpenClaw session data
- โ No external network requests (except git clone during installation)
- โ No sending data to external services
- โ No background monitoring processes or cron jobs
- โ No integration with external notification services (Feishu, webhooks, etc.)
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.
