Why It's Dangerous

  • β€’Agents treat injected instructions as legitimate commands
  • β€’Can override system prompts and safety guidelines
  • β€’Enables unauthorized actions with the agent's full permissions
  • β€’Often invisible to human review

How TrustAgents Protects You

  • βœ“Real-time pattern detection
  • βœ“Semantic analysis of intent
  • βœ“<50ms scan latency
  • βœ“Blocks before agent processes

  TRUSTAGENTS /guard/tool: Scans tool descriptions before registration β›”
              

Why It's Dangerous

  • β€’Tool descriptions are treated as trusted instructions
  • β€’Can redirect agent behavior globally
  • β€’Affects all actions that use the poisoned tool
  • β€’Often bypasses prompt-level security

How TrustAgents Protects You

  • βœ“Real-time pattern detection
  • βœ“Semantic analysis of intent
  • βœ“<50ms scan latency
  • βœ“Blocks before agent processes
