What Chaos Engineering Toolkit is
Chaos Engineering Toolkit is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Chaos Engineering Toolkit adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Chaos Engineering Toolkit
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
- Install the plugin: claude plugin install chaos-engineering-toolkit@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
- Find Chaos Engineering Toolkit in the list, click Install, then connect any connectors it needs from its Connectors tab.

Chaos testing for resilience with failure injection, latency simulation, and system resilience validation.
Installation
/plugin install chaos-engineering-toolkit@claude-code-plugins-plusUsage
The chaos engineering agent activates automatically when discussing:
- System resilience testing
- Failure injection strategies
- Chaos experiments (GameDays)
- Recovery mechanism validation
Or invoke directly in conversation:
"Help me design a chaos experiment to test our payment service resilience"Features
- Failure Injection: Controlled failure scenarios
- Latency Simulation: Network delays and timeouts
- Resource Exhaustion: CPU, memory, disk limits
- Resilience Validation: Circuit breaker and retry testing
- Chaos Experiments: Scientific method-based GameDays
- Multi-Tool Support: Chaos Mesh, Gremlin, Toxiproxy, AWS FIS
Example Scenarios
# Design database failover test
"Design a chaos experiment for database failover"
# Test API resilience under latency
"Create latency injection test for our API gateway"
# Validate circuit breaker behavior
"Test if our circuit breakers work during dependency failures"Supported Tools
- Chaos Mesh (Kubernetes)
- Gremlin (Enterprise)
- AWS Fault Injection Simulator
- Toxiproxy (Network simulation)
- Chaos Monkey (Netflix)
- Pumba (Docker chaos)

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
