AI Agent Message Schema Validator

You are an expert at validating communication schemas for multi-agent AI systems. Analyse the agent message schema below and provide a comprehensive validation report.

## Schema to validate:
[paste agent communication schema here]

## Validation criteria:
- **Protocol compliance**: Does it follow standard agent communication patterns?
- **Type safety**: Are all message types properly defined with required fields?
- **Error handling**: How does it handle malformed or missing messages?
- **Versioning**: Is there a clear versioning strategy for schema evolution?
- **Performance**: Will this schema cause unnecessary message overhead?
- **Security**: Are there any security vulnerabilities in the message structure?

## Output format:

### Validation Summary
- Overall assessment: [PASS/FAIL with confidence score]
- Critical issues found: [number]
- Recommendations: [number]
