### Error System Assessment
|
||||
|
||||
Initialize error coordination by understanding failure landscape.
|
||||
|
||||
Error context query:
|
||||
|
||||
```json
|
||||
{
|
||||
"requesting_agent": "error-coordinator",
|
||||
"request_type": "get_error_context",
|
||||
"payload": {
|
||||
"query": "Error context needed: system architecture, failure patterns, recovery procedures, SLAs, incident history, and resilience goals."
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Development Workflow

## Redis Coordination Patterns
|
||||
|
||||
For comprehensive Redis coordination patterns including error tracking, circuit breakers, retry queues, correlation
|
||||
analysis, and distributed error handling, see:
|
||||
|
||||
**Pattern Documentation:** [`docs/patterns/redis-coordination.md`](../../docs/patterns/redis-coordination.md)
|
||||
|
||||
### Quick Reference
|
||||
|
||||
**Redis MCP for Error Tracking & Recovery**
|
||||
|
||||
The error-coordinator uses **RedisMCPServer** for distributed error tracking, correlation analysis, circuit breaker
|
||||
coordination, and automated recovery orchestration.
|
||||
|
||||
**Key Capabilities:**
|
||||
|
||||
- Error event publishing via pub/sub channels
|
||||
- Chronological error logging with lists
|
||||
- Error correlation across time windows
|
||||
- Circuit breaker state management
|
||||
- Retry queue with exponential backoff and DLQ
|
||||
- Error signature deduplication
|
||||
- Post-mortem data aggregation
|
||||
|
||||
**See pattern documentation for:**
|
||||
|
||||
- Task failure event publishing
|
||||
- Training pipeline error detection
|
||||
- GPU/hardware error monitoring
|
||||
- Agent crash detection and recovery
|
||||
- Error cascade correlation
|
||||
- Circuit breaker patterns (closed/open/half-open)
|
||||
- Retry queue processing with backoff
|
||||
- Integration with performance-monitor and context-manager
|
||||
|
||||
### Production Benefits
|
||||
|
||||
By leveraging Redis MCP for error coordination, the error-coordinator achieves:
|
||||
|
||||
- **Sub-30s Error Detection**: Real-time pub/sub broadcasting
|
||||
- **90%+ Automated Recovery**: Circuit breakers and retry logic
|
||||
- **Cascade Prevention**: Error correlation within 5-minute windows
|
||||
- **Complete Error Context**: Hash-based detailed storage
|
||||
- **Scalable Error Tracking**: Handle 1000+ errors/day
|
||||
- **Flexible Retry Logic**: Exponential backoff with jitter
|
||||
- **Dead Letter Queue**: Manual intervention for retry exhaustion
|
||||
|
||||
Redis provides the high-performance, in-memory backbone for distributed error coordination across the multi-agent
|
||||
system.
