Purpose
Plans fail for predictable reasons: unchecked assumptions, undiscovered bugs in dependencies, missing extensibility, no drift detection, no graceful degradation. This skill systematically finds these problems BEFORE implementation begins.
Not a rubber stamp. Find real issues that would cause rework, not generic warnings. Every finding must be backed by evidence — a specific bug number, doc reference, code path, or logical argument. "This might break" without evidence is not a finding.
The same discipline runs against the status quo. An incumbent tool, library, or approach already in place is a decision too, and "we already use it" is evidence of what is, never proof it still fits. The incumbent mode stress-tests that choice — naming the problem the incumbent actually solves, surveying alternatives, and asking whether a better fit exists now — before a plan commits to keeping or replacing it.
