Monitors active development in real-time to detect and prevent architectural drift and scope creep.
Plan Guardian is a sophisticated background monitoring agent for Claude Code designed to keep development cycles on track. By continuously sampling work-in-progress and comparing it against a structured 'plan digest,' the skill identifies misalignments with the original PRD, technical constraints, or architectural patterns before they require costly rework. Whether you are building an MVP or maintaining a complex system, Plan Guardian acts as an automated project manager that enforces consistency and adherence to your defined technical vision.
