Conflux Release: A Spec-Driven Orchestrator for Parallel AI Development

It is a tool designed to move an entire AI coding workflow forward — implementation, acceptance, archiving, and beyond — with spec-driven development as the foundation. Tools like Claude Code , Codex , and OpenCode have made “writing code” itself much easier. But in real development, the harder problems are different: how to keep the specification in front, how to run multiple changes safely in parallel, and where to place acceptance judgment.

OpenSpec is simply the current concrete means I use for that; the real point is the spec-driven approach itself. Conflux was built to fill that gap. It is not about one-off code generation. It is an orchestration layer for steadily growing a substantial fi
