CrewAI Research Team Demo - Real LLM with Tenuo Protection

Demonstrates what makes Tenuo unique for multi-agent systems:

1. HIERARCHICAL DELEGATION: Manager → Researcher → Writer with narrowing scopes
2. PROMPT INJECTION DEFENSE: LLM can be "tricked" but warrant blocks unauthorized actions
3. CONSTRAINT ENFORCEMENT: Subpath blocks path traversal, UrlSafe blocks SSRF
4. REAL LLM INTEGRATION: See CrewAI agents make tool calls protected by Tenuo
5. ATTACK SIMULATION: Watch attacks get blocked in real-time

1. Prompt injection remains a critical vulnerability in LLM-based agents
2. Cryptographic authorization (like Tenuo) provides defense-in-depth
3. Traditional guardrails can be bypassed through adversarial prompts
4. Multi-agent systems require careful capability delegation

Recommendations:
- Use warrant-based authorization for tool access
- Implement principle of least privilege
- Monitor and audit all agent actions
