chaos-infrastructure-faults

chaos-infrastructure-faults is a skill for Claude Code from dungnotnull/hybrid-harness-chaos-process-prm. It costs 101 tokens per session (3,259 once invoked), scanned C, original, MIT.

A guide for running controlled chaos experiments—deliberately causing infrastructure problems such as node failures, full disks, high CPU or memory use, network failures, and cloud outages.

In plain words
What is it for?
Planning and executing infrastructure fault tests on Kubernetes clusters and cloud resources, with defined limits, monitoring, and runnable Litmus YAML experiment files.
Why use it?
It helps reveal whether systems keep working when the underlying infrastructure fails, without designing each test from scratch.

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 C, and why

chaos-infrastructure-faults scanned grade C with 1 finding 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 12d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

chaos-infrastructure-faults is a skill published in the GitHub repository dungnotnull/hybrid-harness-chaos-process-prm (19 stars, last pushed 3mo ago), licensed MIT. It adds 101 tokens to every session and 3,259 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
