Consult Codex

Multi-turn consultation with Codex CLI. Maintains a conversation across multiple turns using session persistence, unlike single-shot /codex-exec.

Step 1: Gather Context

Identify the 2-5 files most relevant to the problem. Formulate a clear, specific question. Include what has been tried and relevant constraints.

Step 2: Start Session

Run codex exec with -o to capture the response cleanly. Default to -s read-only for safety. Use -s workspace-write when the consultation requires running code or reading files outside the workspace.

All codex Bash calls require dangerouslyDisableSandbox: true (network access to OpenAI API). Use .turbo/ as the temp directory — it is in the working directory (sandbox-writable), gitignored, and avoids $TMPDIR path mismatches between sandbox and non-sandbox mode.

Non-piped codex exec invocations require < /dev/null to avoid hanging on stdin. Codex reads from stdin whenever stdin is non-TTY, and in subprocess contexts the harness leaves stdin connected to a pipe that never EOFs — codex blocks forever, printing only Reading additional input from stdin.... The piped form (cat file | codex exec "...") is safe — cat closes the pipe after the file.

Generate a random session tag at the start to keep files unique for parallel use:
