codex123 is an independent, unofficial local enhancement tool for Codex. It is intended for personal development workflows and open-source study. It is not intended for attacks, abuse, account-permission bypass, or evading platform safety mechanisms.

The project currently focuses on the latest macOS Apple Silicon release. Windows builds, when present, are development artifacts and are not considered fully verified.

Please report security-sensitive issues privately when possible. If GitHub private vulnerability reporting is available for this repository, use it. Otherwise, open a minimal public issue without secrets and state that you need to share security details privately.

Do not include:

• API keys or relay keys.
• auth.json tokens.
• ChatGPT account emails.
• Private Base URLs.
• Full local paths containing personal information.
• Unredacted logs.

codex123 does not modify the original Codex App installation files and does not patch app.asar. Enhancements are applied through an external launcher, manager configuration, and Chromium DevTools Protocol injection.

Remote-control-compatible relay mode is designed to avoid breaking the official ChatGPT login state by keeping relay credentials out of auth.json OPENAI_API_KEY. It cannot guarantee mobile ChatGPT remote-control access, because account eligibility and remote session availability are controlled by OpenAI.

Before sharing diagnostics or opening an issue, redact:

sk-...
OPENAI_API_KEY
access_token
refresh_token
id_token
Bearer ...
experimental_bearer_token

The manager diagnostics are designed to redact secrets, but manual review is still required before posting logs publicly.
