Utilisation de "error-diagnostics-error-analysis". Error: Database connection timeout after 30s in order-service
RĂ©sultat attendu:
- Analysis: Connection pool exhaustion detected
- Root cause: Long-running queries holding all connections
- Recommended fix: Implement query timeout and optimize N+1 patterns
- Prevention: Add circuit breaker and connection pool monitoring
Utilisation de "error-diagnostics-error-analysis". Intermittent 502 errors in API gateway
RĂ©sultat attendu:
- Pattern: Errors occur during peak traffic windows
- Correlation: New autoscaling policy deployed yesterday
- Root cause: Backend services scaling slower than load balancer
- Recommendation: Adjust scaling parameters and add health check validation
Audit de sécurité
SûrAfter evaluating 108 static findings, all detections are false positives. The scanner misinterpreted markdown documentation patterns as security issues: backticks in code blocks were flagged as shell execution, example URLs were flagged as network exfiltration, and environment variable reads in example error-tracking code were flagged as credential access. The sensitive data deletion code (lines 751-752) is a security best practice that removes cookies/authorization headers before sending error reports. This is a legitimate error diagnostics skill providing observability documentation.

Ce que vous pouvez construire
Investigate Production Incidents
Analyze production errors, correlate with deployments, and identify root cause using distributed tracing and log analysis.
Debug Application Errors
Examine stack traces, identify error patterns, and implement fixes for application-level errors.
Improve System Observability
Design and implement comprehensive error tracking, monitoring, and alerting solutions for better incident detection.
Essayez ces prompts
Analyze this error message and stack trace. Identify the likely cause and suggest a fix: $ERROR_MESSAGE
Debug this distributed system error. The error occurred in service $SERVICE_NAME with trace ID $TRACE_ID. Examine the distributed trace and identify which upstream service caused the failure.
Conduct a post-incident review for this outage. Error pattern: $ERROR_PATTERN. Timeline: $TIMELINE. What were the contributing factors and what preventive measures would you recommend?
Design an observability implementation for a Node.js/Express application. Include error tracking setup with Sentry, distributed tracing with OpenTelemetry, and alerting rules for critical errors.
Bonnes pratiques
- Always correlate errors with deployments, configuration changes, and external events
- Implement structured logging with correlation IDs for distributed tracing
- Create retry logic with exponential backoff for transient failures
- Establish error budgets and alerting thresholds based on user impact
Ăviter
- Ignoring intermittent errors - they often indicate systemic issues
- Implementing generic error handling without context-specific recovery
- Sending raw error data to external systems without scrubbing sensitive information
- Setting alerting thresholds too low, causing alert fatigue
