What problem does it solve? It prevents architecture decisions made without evidence by enforcing a structured research-and-decide phase that turns Phase 1 analysis findings into a documented solution strategy with justified decisions and ADRs. ## Core Features & Use Cases - Structured Strategy Document: Creates a solution-strategy.md from a template with five mandatory sections: Key Ideas, Fundamental Decisions, Technology Stack, Architecture Patterns, and Quality Goals. - Research Before Deciding: Requires listing unknowns, investigating alternatives with pros/cons, and justifying each choice with evidence before committing. - Constraint & ADR Compliance: Verifies decisions against existing ADRs, constitution.md, and Phase 4 constraints, and creates new ADRs for major architectural choices. - Use Case: After completing discovery and constraints analysis for a work package, run this phase to produce skill-activation-solution-strategy.md, present the key decisions at a human gate, and only proceed to planning after explicit approval. ## Quick Start Ask the assistant to start Phase 5 STRATEGY for the active work package and produce the solution-strategy document with Key Ideas and ADRs.
