Convert Claude Code Project To Codex - Convert project from Claude Code to Codex with Claude Skill

by•
Session Handoff Skill for Claude Code turns a coding session into a clear handoff.md file so another agent, like OpenAI Codex CLI, can continue the same project without starting from scratch. In the demo, Claude builds a Mini Bug Tracker Dashboard, runs /session-handoff, then Codex reads the handoff and edits the same files. It is not memory sync; the project folder carries the code, and handoff.md carries the context.

Hi Product Hunt, I built Session Handoff Skill for Claude Code while testing a real workflow between Claude Code and OpenAI Codex. I wanted a cleaner way to move a coding project from one agent to another without relying on messy copy-pasted chat summaries. In the demo, Claude Code builds a Mini Bug Tracker Dashboard first. Then a custom Claude skill creates handoff.md with the project state, key files, verification notes, and next steps for Codex. After that, Codex runs from Node.js Command Prompt in the same project folder, reads handoff.md, and continues editing the same files. To make the demo easy to verify, Codex adds a small “Continued by Codex” badge to the app header. What the workflow includes: - Claude Code builds the first version - A project-level skill lives in .claude/skills/session-handoff/SKILL.md - /session-handoff creates a structured handoff.md file - Codex reads handoff.md before editing - Codex continues in the same project folder - A visible UI change proves both agents worked on the same files I would love to hear do you have the same problem with Claude Code, and if this workflow helps you!
