Overview
A skill for designing and analyzing resilience experiments with explicit hypotheses, steady-state metrics, failure conditions, blast-radius controls, and recovery procedures. Use it when planning a controlled failure test with monitoring and cleanup in place. Adapt all example thresholds and scopes to the target system and its safety requirements.
What it does
Chaos Engineering Experiment Designer helps plan, implement, and analyze controlled failure experiments for distributed systems. It starts with a hypothesis about steady-state behavior, defines metrics and thresholds, selects a realistic failure condition, and sets a bounded blast radius. Use beginning with a small scope, monitoring for violations, cleaning up injected faults, and expanding only when the system recovers as expected.
The Examples include staged traffic percentages, service unavailability, network partitions, pod deletion with Litmus, network delay with Chaos Mesh, and an AWS instance termination experiment using Chaos Toolkit. They also show collecting experiment counts, steady-state results, and recovery times with Prometheus metrics. A circuit breaker example tracks errors and can stop an experiment when observed metrics cross configured thresholds.
When to use - and when NOT to
Use this skill when a team needs to test resilience assumptions in a controlled environment and has clear steady-state measures, monitoring, and recovery procedures. It can help structure experiments for service failures, network behavior, or infrastructure events and make the expected hypothesis and abort conditions explicit.
Do not inject failure without authorization, a bounded target, and a tested recovery path. Do not copy the sample thresholds, durations, traffic percentages, service names, or AWS filters as safe defaults. Examples include production experimentation as a principle, but a real production run requires the team's own safeguards, approvals, and blast-radius limits. Stop when steady state is violated or the abort mechanism activates.
Inputs and outputs
Inputs include the system's normal behavior, metrics and KPIs, a failure hypothesis, target service or resource, failure type and duration, blast-radius constraints, monitoring, and cleanup steps. Examples measure response time, availability, error rate, and recovery time.
The output is an experiment plan or configuration with a hypothesis, steady-state probes, failure action, scope, observation procedure, abort criteria, and cleanup. Results can include whether steady state held, recovery time, and experiment status. A progressive plan should capture baseline metrics, inject one controlled failure, monitor for violations, abort and clean up if needed, then recover before advancing. Document the outcome and lessons for later experiments.
Integrations
The material names Chaos Monkey, Litmus, Gremlin, Chaos Toolkit, Chaos Mesh, Kubernetes, AWS EC2, Prometheus, and Python. Examples use Litmus ChaosEngine, Chaos Mesh NetworkChaos, Chaos Toolkit probes and actions, and Prometheus Counter, Gauge, and Histogram metrics. These are example integrations; the source does not establish that a particular environment has them installed or configured.
Who it's for
This skill is for site reliability engineers, platform engineers, and teams responsible for distributed system resilience. It is useful when teams can define measurable steady state and can observe, abort, and reverse an experiment. Keep failure injection scoped and ensure monitoring and cleanup ownership are clear before execution.
