Convert Claude Code Project To Codex

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.
