What You Can Do

You can upload logs and metrics from distributed cloud services—compute, networking, storage, databases—and Claude will parse them to identify failure patterns, map service dependencies, and trace how failures cascade across your infrastructure. The skill generates prioritized remediation steps backed by forensic evidence, plus customer-ready explanations that translate technical findings into business impact.

Features

Multi-service log correlation

Parse and cross-reference logs from compute, networking, storage, and database services to surface hidden failure chains

Failure mode pattern detection

Identify specific root causes (throttling, resource exhaustion, authentication failures, configuration drift) from symptom clusters

Dependency mapping

Visualize how services depend on each other and trace failure propagation through your architecture

Prioritized remediation

Generate actionable steps ranked by impact and urgency with success criteria and validation steps

Forensic RCA documentation

Create detailed incident reports with timeline reconstruction, evidence summaries, and customer-ready explanations

Configuration drift analysis

Compare current configs against baselines to identify unintended changes that triggered incidents

Performance degradation investigation

Correlate metrics spikes with log events to pinpoint root causes of latency and throughput issues

Example Output

Example 1: Cascading Database Failure

Input: CloudWatch logs, RDS metrics, application error logs

Output:

code
ROOT CAUSE: RDS connection pool exhaustion → API request timeout → Client errors

Evidence Timeline:
- 14:23 UTC: RDS CPU spike to 87% (slow query detected)
- 14:24 UTC: Connection count exceeds pool limit (150/150)
- 14:25 UTC: API latency increases from 200ms to 8s
- 14:26 UTC: Client receives 503 Service Unavailable

Remediation (Priority Order):
1. Immediate: Terminate long-running queries blocking pool
2. Short-term: Increase RDS connection pool size to 250
3. Medium-term: Add query timeout enforcement (30s max)
4. Long-term: Implement connection pooling proxy layer

Example 2: Configuration Drift Post-Deployment

Input: Git deployment logs, security group rules, VPC flow logs

Output:

code
ROOT CAUSE: Security group rule misconfiguration post-deployment blocks internal service-to-service communication

Drift Detected:
- Expected: sg-internal allows port 5432 from app tier
- Actual: sg-internal denies all inbound (reverted during rollback)

Impact: Database unreachable → 45 failed requests/second

Fix: Restore security group rule, validate with: `nc -zv database.internal 5432`
