Module codex_auth_import 

Import ChatGPT OAuth credentials from the Codex CLI’s ~/.codex/auth.json.

This implements the “reuse Codex auth.json” integration path described in the DeepWiki analysis of openai/codex: a third-party coding harness can read the OAuth tokens that codex login persisted and use them directly, avoiding a separate browser OAuth dance.

How it works

1. codex login stores ChatGPT OAuth tokens (id_token, access_token, refresh_token) and a derived OPENAI_API_KEY in $CODEX_HOME/auth.json (~/.codex/auth.json by default).
2. VT Code reads that file, parses the token data, and converts it into an OpenAIChatGptSession that the OpenAI provider can use directly.
3. VT Code deliberately does not rotate Codex-owned refresh tokens. Copying or redeeming them could race Codex’s refresh cycle or invalidate Codex-maintained credentials. Instead, CodexAuthJsonRefresher re-reads the auth.json file — which Codex refreshes independently — to obtain fresh tokens when VT Code’s session needs a refresh.
