A reliability claim you have never tested is a hope. "We have a backup," "we can fail over to the secondary," "the system degrades gracefully if the cache is down," "on-call will get paged" — every one of these is an assumption until you have deliberately caused the failure and watched the system (and the humans) handle it. Untested recovery fails exactly when you need it. The discipline (Chaos Engineering — Rosenthal, Jones; Netflix; game days — Allspaw/AWS) is to find the weakness by injecting controlled failure, not by waiting for the real one.
Verify Resilience With Game Days is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/verify-resilience-with-game-days/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when reliability/recoverability is being assumed rather than proven — deliberately inject the failure (dependency down, AZ/region loss, restore from backup, failover, on-call paged) in a controlled game day or chaos experiment, so you learn the system breaks before a real outage teaches you.
The Verify Resilience With Game Days Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 117,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
