How to Share Context Between Claude Code and Codex

Teams using multiple AI coding assistants often struggle with fragmented instructions, session histories, and decisions because each tool stores context separately. The piece recommends standardizing project rules in a shared AGENTS.md file, which Codex reads directly and Claude Code can use when no CLAUDE.md exists, while noting that skills directories may still require separate maintenance or symlinks. It distinguishes persistent rules from task-specific team context, arguing that decisions, experiments, and prior work should be stored outside individual agent harnesses so they remain available across tools and collaborators. As a proposed solution, SageOx’s open-source Ox CLI integrates with several coding agents to record sessions and provide a shared, version-controlled Git-based memory, with configurable recording and local secret filtering. The article presents this approach as a way for teams to switch among Claude Code, Codex, Gemini CLI, and other agents without repeatedly reconstructing institutional knowledge.
