Introduction
HTMA Measure is a portable agent skill for estimating uncertain quantities when a decision depends on the answer. It works for project costs, budgets, vendor quotes, rates, risks, ROI, market size, revenue, and similar questions where a precise-looking guess would be misleading.
The skill converts a vague question into a measurement memo with:
- a precise decision and threshold;
- an explicit quantity, unit, and time horizon;
- confirmed facts separated from assumptions and inference;
- a low / central / high decomposition;
- a calibrated confidence interval;
- the uncertainty most worth reducing next;
- a recommendation tied to the decision; and
- a machine-readable

The key difference
Section titled “The key difference”HTMA Measure does not ask, “What number sounds plausible?” It asks, “What range is defensible, what decision changes across that range, and what evidence is worth buying next?”
That distinction prevents three common failures:
- False precision: a single number disguises uncertainty.
- Research without a stopping rule: the agent gathers easy facts that cannot change the decision.
- Simulation laundering: Monte Carlo output makes weak assumptions look rigorous.
What HTMA means here
