Exec Display

Structured, security-aware command execution with color-coded output.

Why This Skill?

Raw command execution lacks:

• Visibility: Output can be verbose or hidden
• Classification: No indication of command risk level
• Consistency: Different commands, different formats
• Auditability: Hard to track what was executed and why

This skill enforces:

• 4-line max output with summarized results
• Security levels (🟢 SAFE → 🔴 CRITICAL)
• Color-coded ANSI output for terminal visibility
• Purpose documentation for every command

Security Levels

Level	Emoji	Color	Description
SAFE	🟢	Green	Read-only information gathering
LOW	🔵	Blue	Project file modifications
MEDIUM	🟡	Yellow	Configuration changes
HIGH	🟠	Orange	System-level changes
CRITICAL	🔴	Red	Potential data loss, requires confirmation

Usage

Basic Format

python3 {baseDir}/scripts/cmd_display.py <level> "<command>" "<purpose>" "$(<command>)"

Examples

SAFE - Information gathering:

python3 {baseDir}/scripts/cmd_display.py safe "git status --short" "Check repository state" "$(git status --short)"

LOW - File modifications:

python3 {baseDir}/scripts/cmd_display.py low "touch newfile.txt" "Create placeholder file" "$(touch newfile.txt && echo '✓ Created')"

MEDIUM - Config changes:

python3 {baseDir}/scripts/cmd_display.py medium "npm config set registry https://registry.npmjs.org" "Set npm registry" "$(npm config set registry https://registry.npmjs.org && echo '✓ Registry set')"

HIGH - System changes (show for manual execution):

# HIGH/CRITICAL commands should be shown, not executed
python3 {baseDir}/scripts/cmd_display.py high "sudo systemctl restart nginx" "Restart web server" "⚠️ Requires manual execution"

With Warning and Action

python3 {baseDir}/scripts/cmd_display.py medium "rm -rf node_modules" "Clean dependencies" "✓ Removed" "This will delete all installed packages" "Run npm install after"

Output Format

🟢 SAFE: READ-ONLY INFORMATION GATHERING: git status --short
✓  2 modified, 5 untracked
📋 Check repository state

With warning:

🟡 MEDIUM: CONFIGURATION CHANGES: npm config set registry
✓  Registry updated
📋 Set npm registry
⚠️  This affects all npm operations
👉 Verify with: npm config get registry

Agent Integration

MANDATORY RULES

1. ALL exec commands MUST use this wrapper - no exceptions
2. Classify EVERY command by security level before execution
3. Include purpose - explain WHY you're running the command
4. Summarize output - condense verbose output to one line
5. HIGH/CRITICAL commands - show for manual execution, do not run

Classification Guide

🟢 SAFE (execute immediately):

• ls, cat, head, tail, grep, find
• git status, git log, git diff
• pwd, whoami, date, env
• Any read-only command

🔵 LOW (execute, notify):

• touch, mkdir, cp, mv (within project)
• git add, git commit
• File edits within project scope

🟡 MEDIUM (execute with caution):

• npm install, pip install (dependencies)
• Config file modifications
• git push, git pull

🟠 HIGH (show, ask before executing):

• System service commands
• Global package installs
• Network configuration
• Anything affecting system state

🔴 CRITICAL (NEVER execute directly):

• rm -rf on important directories
• sudo commands
• Database drops
• Anything with data loss potential

Customization

Adding to SOUL.md

Add this to your agent's SOUL.md:

## Command Execution Protocol

ALL shell commands MUST use the exec-display wrapper:

1. Classify security level (SAFE/LOW/MEDIUM/HIGH/CRITICAL)
2. Use: `python3 <skill>/scripts/cmd_display.py <level> "<cmd>" "<purpose>" "$(<cmd>)"`
3. HIGH/CRITICAL: Show command for manual execution, do not run
4. Summarize verbose output to one line
5. No exceptions - this is for transparency and auditability

Colors Reference

The script uses ANSI color codes for terminal output:

• Green (32): Success, SAFE level
• Blue (34): LOW level
• Yellow (33): MEDIUM level, warnings
• Bright Yellow (93): HIGH level
• Red (31): CRITICAL level, errors
• Cyan (36): Purpose line

Limitations

This skill provides instructions and tooling for consistent command display. True code-level enforcement requires an OpenClaw plugin with before_tool_call hooks.

For maximum enforcement, also add these rules to your AGENTS.md or workspace config.
