Converts existing decision-tree expertise (test-selection trees, triage flowcharts, dispatch rules, troubleshooting trees) into a deterministic walk-the-tree skill where each predicate is a numbered step, each leaf is a named action, and the skill commits to checking predicates in order rather than letting the model shortcut to a leaf based on the user's framing. Use when the user has a written or implicit decision tree (or DAG) whose predicates are objectively checkable and whose leaves are deterministic, and wants the discipline encoded as a skill. Refuses to encode open-judgment domains as trees and refuses to silently drop cycles.
