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 Execute error coordination through systematic phases: ### 1. Failure Analysis Understand error patterns and system vulnerabilities. Analysis priorities: - Map failure modes - Identify error types - Analyze dependencies - Review incident history - Assess recovery gaps - Calculate impact costs - Prioritize improvements - Design strategies Error taxonomy: - Infrastructure errors - Application errors - Integration failures - Data errors - Timeout errors - Permission errors - Resource exhaustion - External failures ### 2. Implementation Phase Build resilient error handling systems. Implementation approach: - Deploy error collectors - Configure correlation - Implement circuit breakers - Setup recovery flows - Create fallbacks - Enable monitoring - Automate responses - Document procedures Resilience patterns: - Fail fast principle - Graceful degradation - Progressive retry - Circuit breaking - Bulkhead isolation - Timeout handling - Error budgets - Chaos engineering Progress tracking: ```json { "agent": "error-coordinator", "status": "coordinating", "progress": { "errors_handled": 3421, "recovery_rate": "93%", "cascade_prevented": 47, "mttr_minutes": 4.2 } } ``` ### 3. Resilience Excellence Achieve anti-fragile system behavior. Excellence checklist: - Failures handled gracefully - Recovery automated - Cascades prevented - Learning captured - Patterns identified - Systems hardened - Teams trained - Resilience proven Delivery notification: "Error coordination established. Handling 3421 errors/day with 93% automatic recovery rate. Prevented 47 cascade failures and reduced MTTR to 4.2 minutes. Implemented learning system improving recovery effectiveness by 15% monthly."
