ccc-pro-chaos

ccc-pro-chaos is a skill for Claude Code from KevinZai/commander. It costs 18 tokens per session (516 once invoked), scanned A, original, MIT.

A resilience-testing scaffolding pack that introduces controlled failures into services and checks whether they recover. It includes patterns such as timeouts, retries, circuit breakers, degraded responses, and dependency failures.

In plain words
What is it for?
Use it to build fault-injection tests, simulate dependency outages, test graceful degradation and load shedding, and prepare controlled resilience exercises.
Why use it?
It helps reveal how an application behaves when networks, databases, or external APIs are slow, unavailable, or overloaded.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ccc-pro-chaos scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this pack will do

  • Scaffold network partition simulation: DNS failure, TCP timeout, latency injection middleware
  • Generate circuit breaker implementation (half-open state, threshold config, per-dependency)
  • Add bulkhead pattern: thread-pool isolation per dependency, queue depth limits
  • Scaffold retry-with-jitter: exponential backoff + full jitter (AWS best practice)
  • Generate chaos test harness: controlled fault injection in test env, assertion on recovery
  • Add dependency kill switch: feature-flag-gated dependency disablement for safe drills
  • Scaffold graceful degradation paths: cached responses, stale-while-revalidate, stub data
  • Generate load shedding middleware: request queuing, priority lanes, shed-at-threshold
  • Add database failure simulation: connection pool exhaustion, query timeout, replica lag
  • Scaffold external API failure handling: mocked failure responses for Stripe, Twilio, SendGrid
  • Generate GameDay runbook templates: scenario → hypothesis → inject → observe → recover
  • Add chaos engineering CI gate: resilience regression tests on every deploy
  • Scaffold timeout budget propagation: context deadlines through async call chains
  • Generate failure mode catalog per service: FMEA (failure mode and effects analysis) template

Why Pro-only

Chaos engineering patterns require both infrastructure access and deep understanding of failure modes specific to each architectural layer. Naive fault injection can cause cascading failures in test environments. The scaffolding here encodes production-safe patterns used by teams at Netflix, AWS, and Google — not theory.

Coming in v4.2

This skill is scaffolded. Full implementation ships in v4.2. Sign up at commanderplugin.com/pro to get notified and receive early access.

Tier check

This skill checks isPro() from commander/cowork-plugin/lib/license.js before running. If your license tier is starter, it surfaces an upgrade prompt and exits cleanly — no partial scaffolding, no silent failure.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ccc-pro-chaos is a skill published in the GitHub repository KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 516 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
