How do I use the /em:stress-test command?

Run `/em:stress-test ` inside Claude Code to start a structured analysis of a specific belief or projection about your business.

What does the stress-test skill do?

It methodically breaks down business assumptions to identify risks before they impact the market, covering revenue, growth, and competitive landscapes.

Does this skill provide financial models?

It helps model downside scenarios (Bear, Stress, Catastrophic) and calculate sensitivity, providing a structured framework for your existing financial planning.

Why is stress testing important for founders?

It counters natural optimism bias by forcing founders to confront counter-evidence and build contingency plans to ensure business survival.

What types of assumptions can I test?

You can test quantitative assumptions like CAC and revenue targets, or qualitative ones like competitive moats, hiring velocity, and customer retention.

Productivity & Workflow

Identifies and validates critical business assumptions across revenue, market size, and execution to mitigate risk before market entry.

The Stress Test skill provides a rigorous framework for founders and executives to challenge their most optimistic business assumptions. By simulating downside scenarios, searching for counter-evidence, and calculating sensitivity for key performance indicators like CAC, LTV, and hiring velocity, it helps teams move from gut-feeling projections to data-driven, resilient strategies. It is particularly useful during quarterly planning, fundraising preparation, or when launching new products where 'hidden' assumptions can lead to catastrophic failures. The skill guides the user through isolation, modeling, and hedging against high-risk business variables.
