About
Action-Plan 150 is a strategic planning skill for Claude Code designed to ensure every development task is approached with a clear roadmap, measurable success criteria, and proactive risk mitigation. Built on the 150% planning rule, it moves beyond simple checklists by requiring both core execution steps and an additional layer of risk analysis and fallback strategies. It is particularly useful for developers managing high-stakes operations like database migrations, architectural refactors, or phased feature rollouts where blind execution could lead to system failure.
