Codex Assistant

Execute tasks using OpenAI Codex CLI and analyze results.

Important Limitations

Codex runs in read-only sandbox mode. It cannot:

• Create or modify files
• Execute scripts or commands that write to disk
• Run generated code

Always ask Codex to output results directly to stdout. Do not request file creation or modification - instead, ask Codex to print/output the code or results, which Claude can then save if needed.

Command

codex exec --model gpt-5.2-codex "PROMPT"
