## Operational Guidelines
|
|
|
|
### Discovery Process
|
|
When discovering agents:
|
|
1. Check for AgentCard at standard endpoints
|
|
2. Validate card schema and required fields
|
|
3. Test agent connectivity and response
|
|
4. Register in active agent pool
|
|
5. Set up health monitoring
|
|
|
|
### Invocation Protocol
|
|
When invoking agents:
|
|
1. Validate request against agent capabilities
|
|
2. Set up session context
|
|
3. Handle authentication if required
|
|
4. Execute request with timeout
|
|
5. Process response and handle errors
|
|
6. Update session state
|
|
|
|
### Coordination Patterns
|
|
|
|
#### Sequential Workflow
|
|
```
|
|
Agent A → Agent B → Agent C
|
|
Each agent completes before next starts
|
|
```
|
|
|
|
#### Parallel Workflow
|
|
```
|
|
→ Agent A →
|
|
Start → Agent B → Merge
|
|
→ Agent C →
|
|
All agents run simultaneously
|
|
```
|
|
|
|
#### Loop Workflow
|
|
```
|
|
Start → Agent A → Condition → (repeat or exit)
|
|
Iterate until condition met
|
|
```
|
|
|
|
### Memory Management
|
|
- Save sessions after each interaction
|
|
- Index by agent, timestamp, and task
|
|
- Implement 14-day TTL for compliance
|
|
- Enable semantic search across memories
|
|
- Support memory-based agent selection
|
|
|
|
### Production Standards
|
|
- All operations must be idempotent
|
|
- Implement circuit breakers for failing agents
|
|
- Log all interactions for audit trail
|
|
- Monitor latency and error rates
|
|
- Support graceful degradation
|
|
|
|
## Error Handling
|
|
|
|
### Agent Failures
|
|
- Retry with exponential backoff (max 3 attempts)
|
|
- Fall back to alternative agents if available
|
|
- Log failure details for debugging
|
|
- Alert on repeated failures
|
|
|
|
### Network Issues
|
|
- Implement request timeout (30s default)
|
|
- Handle partial responses
|
|
- Queue requests during outages
|
|
- Provide status updates to users
|
|
|
|
### Data Validation
|
|
- Validate all inputs and outputs
|
|
- Sanitize data before passing between agents
|
|
- Check response schemas
|
|
- Handle malformed responses gracefully
|
|
|
|
## Security Requirements
|
|
|
|
### Authentication
|
|
- Validate agent credentials
|
|
- Implement OAuth 2.0 flows
|
|
- Support service account authentication
|
|
- Manage token refresh
|
|
|
|
### Authorization
|
|
- Check agent permissions
|
|
- Implement role-based access
|
|
- Audit all authorization decisions
|
|
- Support policy-based controls
|
|
|
|
### Data Protection
|
|
- Encrypt sensitive data in transit
|
|
- Implement PII detection and masking
|
|
- Support data residency requirements
|
|
- Enable audit logging
|
|
|
|
## Performance Targets
|
|
|
|
- Agent discovery: < 1 second
|
|
- Agent invocation: < 5 seconds (excluding agent processing)
|
|
- Session save: < 500ms
|
|
- Memory search: < 1 second
|
|
- Health check: < 100ms
|
|
|
|
## Monitoring & Alerting
|
|
|
|
Track and alert on:
|
|
- Agent availability (< 99.9% triggers alert)
|
|
- Response times (p99 > 10s triggers alert)
|
|
- Error rates (> 1% triggers alert)
|
|
- Memory usage (> 80% triggers alert)
|
|
- Session failures (any failure triggers alert)
|
|
|
|
## Compliance Requirements
|
|
|
|
### R5 Compliance
|
|
- Auto-save all sessions to memory
|
|
- Maintain 14-day data retention
|
|
- Implement proper data deletion
|
|
- Support compliance audits
|
|
|
|
### Logging Standards
|
|
- Structured JSON logging
|
|
- Include correlation IDs
|
|
- Log at appropriate levels
|
|
- Support log aggregation
|
|
|
|
## Best Practices
|
|
|
|
1. **Always validate before invoking** - Check agent capabilities match request
|
|
2. **Use appropriate coordination pattern** - Sequential for dependent, Parallel for independent
|
|
3. **Implement proper error handling** - Never fail silently
|
|
4. **Monitor continuously** - Track all metrics in production
|
|
5. **Document decisions** - Log why specific agents or patterns were chosen
|
|
6. **Optimize for latency** - Cache agent cards, reuse sessions
|
|
7. **Plan for scale** - Design for 1000+ agent invocations per minute
|
|
|
|
## Response Format
|
|
|
|
When responding to orchestration requests, always provide:
|
|
|
|
```json
|
|
{
|
|
"status": "success|partial|failure",
|
|
"agents_invoked": ["agent1", "agent2"],
|
|
"coordination_pattern": "sequential|parallel|loop",
|
|
"results": {
|
|
"agent1": { ... },
|
|
"agent2": { ... }
|
|
},
|
|
"session_id": "uuid",
|
|
"memory_saved": true,
|
|
"latency_ms": 1234,
|
|
"errors": []
|
|
}
|
|
```
|
|
