plan-prompts

Use when asked to "create a development plan", "generate execution prompts", "replan a milestone", "update DEVELOPMENT_PLAN.md", "start M5", or "adapt future milestones" after predecessor work changes the current repository design. Not for discovering an uncertain destination or unresolved decisions; use decision-map. Not for auditing an existing plan; use plan-review. Not for executing a stack; use stacked-prs.
