Chaos Engineer

When to Use This Skill

Designing and executing chaos experiments
Implementing failure injection frameworks (Chaos Monkey, Litmus, etc.)
Planning and conducting game day exercises
Building blast radius controls and safety mechanisms
Setting up continuous chaos testing in CI/CD
Improving system resilience based on experiment findings

Core Workflow

System Analysis - Map architecture, dependencies, critical paths, and failure modes
Experiment Design - Define hypothesis, steady state, blast radius, and safety controls
Execute Chaos - Run controlled experiments with monitoring and quick rollback
Learn & Improve - Document findings, implement fixes, enhance monitoring
Automate - Integrate chaos testing into CI/CD for continuous resilience

Reference Guide

Load detailed guidance based on context:

Topic	Reference	Load When
Experiments	`references/experiment-design.md`	Designing hypothesis, blast radius, rollback
Infrastructure	`references/infrastructure-chaos.md`	Server, network, zone, region failures
Kubernetes	`references/kubernetes-chaos.md`	Pod, node, Litmus, chaos mesh experiments
Tools & Automation	`references/chaos-tools.md`	Chaos Monkey, Gremlin, Pumba, CI/CD integration
Game Days	`references/game-days.md`	Planning, executing, learning from game days

Safety Checklist

Non-obvious constraints that must be enforced on every experiment:

Steady state first — define and verify baseline metrics before injecting any failure
Blast radius cap — start with the smallest possible impact scope; expand only after validation
Automated rollback ≤ 30 seconds — abort path must be scripted and tested before the experiment begins
Single variable — change only one failure condition at a time until behaviour is well understood
No production without safety nets — customer-facing environments require circuit breakers, feature flags, or canary isolation
Close the loop — every experiment must produce a written learning summary and at least one tracked improvement

Output Templates

When implementing chaos engineering, provide:

Experiment design document (hypothesis, metrics, blast radius)
Implementation code (failure injection scripts/manifests)
Monitoring setup and alert configuration
Rollback procedures and safety controls
Learning summary and improvement recommendations

Concrete Example: Pod Failure Experiment (Litmus Chaos)

The following shows a complete experiment — from hypothesis to rollback — using Litmus Chaos on Kubernetes.

Step 1 — Define steady state and apply the experiment

# Verify baseline: p99 latency < 200ms, error rate < 0.1%
kubectl get deploy my-service -n production
kubectl top pods -n production -l app=my-service

Step 2 — Create and apply a Litmus ChaosEngine manifest

# chaos-pod-delete.yaml
apiVersion: litmuschaos.io/v1alpha1
kind: ChaosEngine
metadata:
  name: my-service-pod-delete
  namespace: production
spec:
  appinfo:
    appns: production
    applabel: "app=my-service"
    appkind: deployment
  # Limit blast radius: only 1 replica at a time
  engineState: active
  chaosServiceAccount: litmus-admin
  experiments:
    - name: pod-delete
      spec:
        components:
          env:
            - name: TOTAL_CHAOS_DURATION
              value: "60"          # seconds
            - name: CHAOS_INTERVAL
              value: "20"          # delete one pod every 20s
            - name: FORCE
              value: "false"
            - name: PODS_AFFECTED_PERC
              value: "33"          # max 33% of replicas affected

# Apply the experiment
kubectl apply -f chaos-pod-delete.yaml

# Watch experiment status
kubectl describe chaosengine my-service-pod-delete -n production
kubectl get chaosresult my-service-pod-delete-pod-delete -n production -w

Step 3 — Monitor during the experiment

# Tail application logs for errors
kubectl logs -l app=my-service -n production --since=2m -f

# Check ChaosResult verdict when complete
kubectl get chaosresult my-service-pod-delete-pod-delete \
  -n production -o jsonpath='{.status.experimentStatus.verdict}'

Step 4 — Rollback / abort if steady state is violated

# Immediately stop the experiment
kubectl patch chaosengine my-service-pod-delete \
  -n production --type merge -p '{"spec":{"engineState":"stop"}}'

# Confirm all pods are healthy
kubectl rollout status deployment/my-service -n production

Concrete Example: Network Latency with toxiproxy

# Install toxiproxy CLI
brew install toxiproxy   # macOS; use the binary release on Linux

# Start toxiproxy server (runs alongside your service)
toxiproxy-server &

# Create a proxy for your downstream dependency
toxiproxy-cli create -l 0.0.0.0:22222 -u downstream-db:5432 db-proxy

# Inject 300ms latency with 10% jitter — blast radius: this proxy only
toxiproxy-cli toxic add db-proxy -t latency -a latency=300 -a jitter=30

# Run your load test / observe metrics here ...

# Remove the toxic to restore normal behaviour
toxiproxy-cli toxic remove db-proxy -n latency_downstream

Concrete Example: Chaos Monkey (Spinnaker / standalone)

# chaos-monkey-config.yml — restrict to a single ASG
deployment:
  enabled: true
  regionIndependence: false
chaos:
  enabled: true
  meanTimeBetweenKillsInWorkDays: 2
  minTimeBetweenKillsInWorkDays: 1
  grouping: APP           # kill one instance per app, not per cluster
  exceptions:
    - account: production
      region: us-east-1
      detail: "*-canary"  # never kill canary instances

# Apply and trigger a manual kill for testing
chaos-monkey --app my-service --account staging --dry-run false

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Dependency or permission surface needs review
Permission surface may require sandboxing
Reference examples contain intentionally destructive commands (e.g., AWS instance termination, pod deletion, CPU injection); these are appropriate for chaos engineering but could be dangerous if copied without the skill's own safety checklist.
The SKILL.md excerpt appears to end mid-command in the monitoring example, so verify the full file is not truncated in the repository.

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
