Sentinel - AI Agent State Guardian

Use this skill to protect AI agent workspaces from corruption, accidental changes, and data loss. Sentinel hashes your critical files, detects unexpected changes, creates rolling backups, and restores from backup when corruption is detected.

When to Use This Skill

Invoke this skill when:

• A user wants to protect their agent workspace from accidental overwrites
• You need to detect if critical files (agent config, memory/, state files) were modified unexpectedly
• Auto-backup is needed before any destructive operation
• You need to restore a workspace to a known-good state after corruption
