Purpose: This article shows how to reliably hand off work between Claude Code and Codex using SpecKit with a simple project-level governance layer.
AI coding works well inside a single session. It breaks when work moves between agents. The context gets lost, decisions drift, and each agent starts re-figuring out what was already known. Frankly, it becomes annoying, fast. This is not a model problem, but a system problem.
What you need is a way to make context durable so any agent can pick up exactly where the last one left off. That’s where SpecKit helps, but only if you add a missing layer, and wire up with your coding agent.
