What it does

Chaos is an agent skill from softspark/ai-toolkit. Injects controlled faults for resilience testing on non-prod. Triggers: chaos, fault injection, latency injection, dependency kill, resilience test.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Chaos engineering. The repository describes itself as: Professional-grade AI coding toolkit: 94 skills, 44 agents, multi-platform (Claude, Cursor, Windsurf, Copilot, Gemini, Cline, Roo Code, Aider, Augment, Antigravity, Codex CLI… The licence is Apache-2.0.

When your agent uses it

Tasks that involve Chaos engineering

Example prompts

“Use the chaos skill to inject controlled faults for resilience testing on non-prod”
“/chaos”

Requirements

Docker
Pre-approved tools (allowed-tools): Bash, Read

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

Safety Check: Verify env != PROD.
Baseline: Check system health is green.
Inject: Run the fault injection.
Observe: Monitor logs/metrics for 60s.
Recover: Restore system health.
Report: Did we survive?

What it can do on your machine

Read from SKILL.md and the folder at commit d64db2b. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash
- Read
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- docker
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Chaos loads about 579 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 266 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~39
When it runs · the whole SKILL.md, loaded when a task matches: ~579

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
```
allowed-tools: Bash, Read
```

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Chaos Command

$ARGUMENTS

Triggers a controlled resilience experiment.

Usage

bash

/chaos <experiment> [target]
# Example: /chaos latency backend-api
# Example: /chaos kill redis

Protocol

Safety Check: Verify env != PROD.
Baseline: Check system health is green.
Inject: Run the fault injection.
Observe: Monitor logs/metrics for 60s.
Recover: Restore system health.
Report: Did we survive?

Rules

MUST verify target environment is non-production before injecting
NEVER run against a system without a healthy baseline
CRITICAL: abort immediately if recovery does not complete within the observation window
MANDATORY: log every injected fault with timestamp and scope

Gotchas

NODE_ENV=production on a developer's machine is common — checking that env var alone is not enough proof of non-prod. Combine with kubeconfig context, cloud account ID, or a project-specific env file check before injecting.
docker stats reports cached values; the first sample immediately after injection is often pre-fault. Wait at least 5 seconds before reading metrics.
Kubernetes liveness probes may self-heal the faulted pod inside the 60s observation window — the report shows green while the workload is still flapping. Check pod restart counters, not just health endpoints.
Latency injected with tc (Linux traffic control) persists across container restarts on the host and across SIGTERM. Always pair the inject step with an explicit tc qdisc del dev <iface> root cleanup in the recover step — the fork context will not undo it for you.

When NOT to Use

In production without an explicit, written runbook — use /workflow incident-response for real incidents
When the system has no observability (no metrics, no logs) — fix observability first
For load testing — use dedicated load-test tooling, not chaos injection
During an active incident — stabilize first with /panic, then investigate

Questions about Chaos

What does Chaos do?

Injects controlled faults for resilience testing on non-prod. Chaos is an agent skill from softspark/ai-toolkit. Injects controlled faults for resilience testing on non-prod.

When should I use Chaos?

Chaos fits situations like: tasks that involve Chaos engineering.

How do I install Chaos in Claude Code?

Run `npx skills add softspark/ai-toolkit --skill chaos -a claude-code`. Or copy the skill folder (app/skills/chaos in softspark/ai-toolkit) into .claude/skills/chaos in your project. Claude Code loads it when a task matches its description.

How do I install Chaos in Codex?

Run `npx skills add softspark/ai-toolkit --skill chaos -a codex`. Or copy the skill folder (app/skills/chaos in softspark/ai-toolkit) into .agents/skills/chaos in your project. Codex loads it when a task matches its description.

Can I use Chaos in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add softspark/ai-toolkit --skill chaos -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/chaos, .gemini/skills/chaos, .github/skills/chaos and .opencode/skills/chaos in your project.

What does Chaos need to run?

Going by SKILL.md and its folder, Chaos needs the command-line tools its instructions call (docker). Our summary lists: Docker. Its frontmatter pre-approves these tools: Bash, Read.

Does Chaos access the network?

SKILL.md contains no URLs. Its commands use docker, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Chaos safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Chaos use?

Chaos is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Chaos use?

About 579 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Chaos?

Skills that share tags, products or a category with Chaos: Executing Distributed System Tests (shenli/distributed-system-testing, 231 stars), Audit Review (testflows/TestFlows-GitHub-Hetzner-Runners, 102 stars), Chaos Dr Test (harness/harness-skills, 115 stars) and Chaos Experiment (harness/harness-skills, 115 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Chaos?

softspark (a GitHub user) maintains it in softspark/ai-toolkit, which has 179 GitHub stars. The repository holds 112 skills in this directory. The repository was last updated on October 7, 2026.
