What kind of assumptions can I stress test?

You can test any specific business assumption including revenue projections, market size (TAM/SAM/SOM), customer retention rates, competitive moats, and hiring velocity.

What is a 'hedge' in this context?

A hedge is a recommended action—such as a pilot program or an early-warning indicator—designed to protect the business if the primary assumption proves to be incorrect.

How does the stress-test command work?

Simply use the command '/em:stress-test ' within Claude Code. Claude will then analyze the statement, find counter-evidence, and model potential downsides.

Is this skill only for startup founders?

While optimized for leadership, it is highly valuable for product managers, developers, and strategists who need to validate the business logic behind their technical roadmap.

Evaluates and challenges business assumptions through rigorous counter-evidence, downside modeling, and sensitivity analysis.

This skill acts as an executive mentor within Claude Code, helping founders and leaders pressure-test their most critical business assumptions. By moving beyond optimism, it isolates specific variables like market size, customer behavior, and revenue projections to identify potential points of failure. The skill provides a structured methodology to surface counter-evidence, model bear-case scenarios, and propose strategic hedges, ensuring business models are resilient and calibrated before they face real-world market conditions.
