decomposition-planning-roadmap

What problem does it solve? Breaking a monolithic application into distributed services without a structured plan leads to missed dependencies, unrealistic timelines, and stalled migrations. This Skill assesses the current state of decomposition, prioritizes work by risk and value, and produces a phased roadmap with milestones, architecture stories, and progress tracking. ## Core Features & Use Cases - Current State Assessment: Evaluates which of the six component-based decomposition patterns (identify, gather, flatten, analyze dependencies, group domains, extract services) are complete, in progress, or not started. - Prioritization Framework: Scores work items using a formula based on value, risk, and dependencies, and maps them onto a value/risk prioritization matrix. - Phased Roadmap & Stories: Generates phased roadmaps with milestones and timelines, plus architecture stories with acceptance criteria and story-point estimates. - Use Case: An architect planning a monolith-to-microservices migration asks for a decomposition roadmap and receives a current-state assessment, a three-phase plan with weekly milestones, a prioritized work plan, and a progress dashboard. ## Quick Start Ask the agent to create a decomposition roadmap for this codebase based on the current component analysis.
