List every variable, map which ones constrain or influence others, then resolve them in dependency order from most-constrained to most flexible. This Skill automates that process and produces a structured decision tree with a final recommendation.

Use it when a decision has more than three interacting variables and choosing one option changes what is valid for the others. For single-dimension or linear problems, a simpler problem-solving approach is more efficient.

A two-way door decision is reversible with low switching cost, so it deserves light analysis and a review date. A one-way door decision is irreversible and high-stakes, requiring full sequential analysis including second-order effects and bias checks.

It cross-checks for three biases: anchoring (did the first resolved variable over-constrain the rest), status quo (was the current approach unfairly favored), and overconfidence (are confidence levels justified). Detected biases are reported with their impact on the recommendation.

The cycle is flagged explicitly and broken by treating one variable as a fixed assumption. The analysis then proceeds in dependency order from that assumption, and the assumption is noted in the final report.

It is stateless with no memory between calls, and it is inefficient for simple linear problems. When more than eight variables exist, related ones must be grouped into composite variables to keep the analysis tractable.
