GSD is the lifecycle execution engine and Superpowers provides useful helper disciplines. Silver Bullet sits above them as an Agentic Process Orchestrator: it composes the task-specific path, routes across plugins, adds quality and release gates, and enforces traceability through hooks where the runtime supports them.
Scores are weighted by feature priority: Critical = 5×, High = 3×, Medium = 2×, Low = 1×. A higher score means broader, more important coverage.
Silver Bullet leads as the orchestration layer. GSD leads in lifecycle execution. Superpowers contributes selected craft-discipline helpers when SB routes to them.
