What problem does it solve?
This Skill helps you evaluate whether a software design is merely working under normal conditions or is dangerously fragile under stress. It is built for situations where rare but severe failures matter more than average performance, such as migrations, critical dependencies, security-sensitive systems, and irreversible architectural bets.
Core Features & Use Cases
- Ruin and Tail-Risk Review: Identifies absorbing failures, nonlinear downside, hidden coupling, and short-volatility tradeoffs that can turn small shocks into catastrophic outcomes.
- Safer Design Recommendations: Reframes abstract risk concerns into concrete engineering moves such as deletion, isolation, rollback paths, canaries, kill switches, bounded experiments, and barbell design.
- False Confidence Audit: Challenges overconfidence based on CI passes, staging success, uptime, or benchmarks by asking what evidence would still look good if the system were actually fragile.
- Use Case: Before a major database migration or vendor integration, use this Skill to surface irreversible failure modes, identify where rollback is weak, and propose changes that cap downside while preserving learning and optionality.
Quick Start
Ask the antifragility-and-tail-risk skill to review your planned migration or architecture decision for ruin risks, false confidence, fragility surfaces, and the safest asymmetric changes.
