# CodexShift

CodexShift is a standalone Codex data-migration and index-maintenance tool: when switching official accounts or third-party APIs, it also syncs Provider references on historical tasks so old sessions do not become orphans, duplicates, or vanish from history after a switch. It does not depend on other Provider managers and does not read or modify their data. Features — Built-in "OpenAI official account (native)" entry to restore saved official login credentials or return to the native login flow. Create, edit, delete third-party API configs. Probe API Key and endpoint connectivity and auto-discover models from OpenAI-compatible /models. Switch configs and auth credentials, auto-cleaning conflicting account fields. Auto-detect the current user's CODEX_HOME / ~/.codex, with manual path selection. Historical task index sync (core): scan rollout files, unify model_provider inside them, update state_5.sqlite, and backfill missing root-task indexes so historical sessions stay visible and openable after switches. Selective bidirectional chat migration by project and session between Codex and DeepSeek Harness, auto-creating matching projects and restoring visible user/assistant context.
