Category: Security  ·  Sub-category: malware-analysis  ·  Last updated:
type:audit
Runtime security guardian for OpenClaw agents. Use this skill whenever the user mentions security, skill safety, prompt injection, malware, suspicious behavior, credential leaks, network monitoring, skill integrity, or the ClawHavoc attack. Also trigger for phrases like "is this skill safe", "audit my skills", "check for threats", "my agent is acting weird", "scan for malware", "protect my agent", or any concern about what installed skills are doing at runtime. runtime-sentinel provides five active defenses: skill integrity hashing, prompt injection detection, credential exposure auditing, network egress monitoring, and process anomaly detection. Free tier covers hashing and basic injection scanning. Premium features (continuous daemon, egress monitoring, process anomaly detection) are gated via x402 USDC micropayments on Base — no account or API key required.

From the source SKILL.md
