AgentGuard - Security Monitoring Skill

Version: 1.0.0

Category: Security & Monitoring

Overview

AgentGuard is a comprehensive security monitoring skill that watches over agent operations, detecting suspicious behavior, logging communications, and providing actionable security reports.

Usage Examples

Start Full Monitoring

agentguard start

Enables all monitoring features with default config.

Check Current Security Status

agentguard status

Returns current threat level, active monitors, recent alerts.

Investigate Specific Activity

agentguard investigate --timerange "last 2 hours" --type file_access

Generate Immediate Report

agentguard report --now

Review Alert History

agentguard alerts --last 24h --severity high

Whitelist a Domain

agentguard trust add api.newservice.com --reason "Required for X integration"

Alert Severity Levels

Level

Color

Meaning

Example

INFO	🔵	Normal logged activity	File read in workspace
LOW	🟢	Minor deviation	Slightly elevated API calls
MEDIUM	🟡	Notable anomaly	Access to .env file
HIGH	🟠	Potential threat	Bulk credential access
CRITICAL	🔴	Immediate action needed	Data exfiltration pattern

Integration Points

With Clawdbot

• Receives file/API operation hooks
• Sends alerts via configured channels
• Integrates with heartbeat for periodic checks

With Other Skills

• Shares threat data with other security skills
• Can block operations (if configured)
• Provides audit logs for compliance skills

Privacy & Security

• No external data transmission - All processing is local
• Sensitive data hashing - Credentials are never logged in plain text
• Configurable retention - Auto-delete old logs
• Encrypted storage - Optional AES encryption for logs

---

Troubleshooting

High false positive rate

→ Increase baseline learning period or reduce sensitivity

Missing file events

→ Check file_watch_dirs config covers target directories

Reports not generating

→ Verify report_time format and timezone settings

Author Notes

AgentGuard is designed with defense-in-depth principles. It assumes agents can be compromised or manipulated, and provides visibility into their operations.

For maximum security, run AgentGuard in a separate process with limited write access to prevent a compromised agent from disabling monitoring.
