概要
The apex:plan skill manages the critical transition between research and code implementation within the Apex workflow. Acting as a specialized 'Architect' role, it requires Claude to validate research evidence, generate three distinct architectural solutions via Tree of Thought analysis, and rigorously apply YAGNI principles. By enforcing five mandatory design artifacts—including pattern selection rationale and a 'Chain of Draft' evolution—it ensures that developers receive a validated, low-risk roadmap with clear implementation sequences and validation plans before any production code is written.
