codex-with-chatgpt
ChatGPT thinks. Codex works. Use ChatGPT as the planning brain while keeping the Codex harness.
Bottom line: Signal-based grade (4/7 points): very widely starred on GitHub, public source code. This reflects adoption and transparency, not a code review.

What it does
Combines ChatGPT's planning capabilities with Codex execution to enable AI agents that reason through tasks before acting. Routes complex decisions through ChatGPT while maintaining deterministic code execution through the Codex harness.
Who it’s for
Builders integrating reasoning and execution layers into AI agents, and teams wanting ChatGPT-powered planning without sacrificing code-level control. Best suited for applications requiring explainable decision-making paths.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Verify against the repo README at https://github.com/XiaoDuoYa/codex-with-chatgpt (opens external site) for current installation steps. Likely involves:
npm install codex-with-chatgpt
Then configure with ChatGPT API credentials and Codex harness endpoints per repository documentation.
Risks
- ChatGPT API credentials embedded in agent config risk exposure if harness or environment is compromised
- Prompt injection vectors at the planning layer could manipulate ChatGPT reasoning before Codex execution
- Data exfiltration risk if prompts or execution results are sent to ChatGPT containing sensitive information
- Limited transparency on how ChatGPT responses map to Codex actions; unclear guardrails between planning and execution
- Supply chain risk: repository maintenance appears inactive (0 weekly npm downloads suggests low adoption/testing)
How to stay secure
Least-privilege permissions
- Store ChatGPT API keys in a secure vault (like a locked digital safe) separate from your code, never directly in config files or code repositories
- Give the Codex execution layer only the minimum permissions needed to do its job—if it only needs to read files, don't give it write or delete access
- Restrict which systems or data sources the connector can access; segment sensitive data so the agent can't reach it unless absolutely necessary
- Rotate (change) API credentials regularly and audit who has access to them
Network isolation
- Run the connector on a dedicated, isolated network segment or server that doesn't have open access to your entire infrastructure
- Block outbound internet connections except to the specific ChatGPT API endpoints required; disable unnecessary external communication
- Use a firewall to control what data can enter or leave the system; log all network traffic for review
- If possible, route ChatGPT API calls through a proxy server you control to inspect and filter requests before they leave your environment
Monitoring
- Log every request sent to ChatGPT and every action Codex takes; keep these records for at least 90 days
- Alert your security team immediately if the connector tries to access files or systems outside its normal scope
- Track API usage patterns—sudden spikes in requests could indicate a compromise or attack
- Periodically review logs to catch unusual behavior, like requests containing sensitive data types you didn't expect
Red flags to watch for
- Any prompts or results containing passwords, tokens, personal information, or confidential business data being sent to ChatGPT
- The connector suddenly accessing new files, databases, or systems it wasn't configured to use
- Requests to update or modify the connector's permissions or configuration coming from unknown sources
- No recent security updates or maintenance from the repository maintainers; verify the code hasn't been abandoned before continued use
Alternatives
- Anthropic Claude + MCP servers (native planning + tool integration, better documented)
- LangChain Agent with tool bindings (broader framework, more community maintenance)
- OpenAI Assistants API (integrated reasoning and function calling, officially supported)
- Custom orchestration layer combining GPT-4 with your own execution engine (full control, higher complexity)
