codex-verifier

Verification with Codex uses the codex exec CLI to run independent analysis on your code. Invoke codex exec with your verification prompt, capture output to a temporary file, and compare results against your initial analysis for cross-validation.

Second-opinion verification delegates read-only analysis to Codex CLI as an independent agent. Pass your code, configuration, or plan as context in a prompt via codex exec, set a timeout for reproducibility, and review Codex's findings alongside your own conclusions.

Yes, Codex verification is read-only and non-destructive. Use codex exec with the --dangerously-bypass-approvals-and-sandbox flag and redirect stderr to /dev/null, allowing exploration of alternatives without side effects on your actual code or data.

Capture Codex output by creating a temporary file with mktemp, passing its path to codex exec via the -o flag, then cat the file to view results. This approach isolates Codex responses and prevents context pollution in your workflow.

Run codex exec --help to retrieve current CLI syntax, model options, and flags. The metadata documents core options like --model, --dangerously-bypass-approvals-and-sandbox, and -o for output, with 15-minute timeout defaults for stability.

Use Codex verification when you need independent validation of assumptions, want to explore alternative approaches, cross-check complex analyses, or require reproducible read-only exploration of code, configurations, plans, or data without committing to changes.
