Claude Code finds hidden bug by designing chaos experiments

An experiment using Claude Code to design chaos engineering scenarios for a payment service revealed a previously undetected six-month-old bug. The AI proposed four experiments, three of which ran without issue in staging, but the fourth caused a complete outage. This incident highlighted a production pattern of pool exhaustion leading to retry storms and rate limiter self-denial-of-service, which had been observed but not reproducible for months. The author outlines three new requirements for AI-driven chaos experiment design. AI

IMPACT Demonstrates AI's capability to uncover complex, long-standing bugs in production systems through simulated stress testing.

RANK_REASON The article describes the use of an AI model (Claude Code) with a specific tool (Steadybit MCP server) to perform chaos engineering, which is a product-focused application rather than a core AI release.

    I Let Claude Design 4 Chaos Experiments via MCP. The 4th Took Down Staging and Found a 6-Month-Old Bug.

    <p>Every experiment in this post ran in staging. Production was double-locked: a <code>## Chaos Rules</code> block in CLAUDE.md forbidding production targets, and a <code>PreToolUse</code> hook that exits 2 if <code>--env=production</code> shows up in any chaos command. I'll show…
