# Claude-Codex Switch Skill Convert coding-agent sessions between **Claude Code** and **Codex** so you can switch frameworks mid-task without losing context — typically because one side's quota ran out. Both directions are supported: - **Claude → Codex**: reads `~/.claude/projects/<slug>/<id>.jsonl`, writes a Codex `rollout-*.jsonl` under `~/.codex/sessions/YYYY/MM/DD/`, and registers the session in `~/.codex/state_5.sqlite` so Codex lists it in history. - **Codex → Claude**: reads `~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`, writes a Claude-compatible JSONL into `~/.claude/projects/<slug>/`, and injects a `migration_boundary` system message so Claude's transcript shows the origin clearly. ## When to use The user says any of: - "Convert this Claude session to Codex" / "把这次 Claude 会话转给 Codex" - "Convert my Codex session to Claude" / "把 Codex 会话转成 Claude" - "I hit my Codex quota, switch me to Claude with the same context" - "Import this Claude rollout into Codex" - "Migrate the session to the other agent" ## Migrated session title Both directions produce a title with the pattern: ``` From Claude - <original session name> - YYYY-MM-DD HH:MM:SS From Codex - <original session name> - YYYY-MM-DD HH:MM:SS ``` The original session name comes from: - Claude → Codex: the first non-synthetic user message in the Claude session. - Codex → Claude: the `title` column in Codex's `threads` table (looked up by session id), falling back to the first user message.
