wb-flow vs Spec Kit

Dimension	wb-flow	Spec Kit
Execution (plan → parallel verified changes)	✓	partial
Planning (intent → executable task graph)	✓	✓
Artifact traceability (task → explain/execute/validate links)	✓	—

Architecture

GitHub Spec Kit optimizes for a standardized spec methodology backed by a large ecosystem (including numerous integrations and a workflow engine). It converts standard specs into plans and tasks efficiently. wb-flow focuses more directly on composable planning, model routing, explicit wave execution, and the artifact graph that links explanations and validations for each task.

Decision Framework

• Choose Spec Kit if: you have a standard spec → plan → tasks workflow and want to leverage a huge ecosystem where the workflow engine natively handles loops and fan-out.
• Choose wb-flow if: you need full engineering traceability, composable planning, and explicit wave-based execution.
