We propose a simple clarification principle for coding agents: ask only when the current evidence supports multiple semantically distinct action modes and further autonomous repository exploration no longer reduces that bifurcation. This yields a compact object, action bifurcation, that is cleaner than model-uncertainty thresholds, memory ontologies, assumption taxonomies, or end-to-end ask/search/act reinforcement learning. The method samples multiple commit-level actions from a frozen strong agent, clusters them into semantic modes, measures ambiguity from cross-mode mass and separation, and estimates reducibility by granting a small additional self-search budget before recomputing ambiguity. The resulting stopping rule is: ask when ambiguity is high and reducibility is low. We position this as a method and evaluation proposal aligned with ambiguity-focused benchmarks such as Ambig-SWE, ClarEval, and SLUMP.
