FAQPage Schema
How do I run Codex CLI commands non-interactively for CI/CD automation?▼

Run Codex CLI commands non-interactively for CI/CD automation by using codex exec and codex review with explicit flags like --full-auto. This skill enforces structured execution patterns to ensure reliable, headless code analysis and prompt-driven workflows.

What is the difference between codex exec and codex review for automated code analysis?▼

Codex exec and codex review serve distinct automation roles: exec handles prompt-driven command execution while review targets code analysis across branches, commits, and working trees. This skill clarifies their semantics to ensure repeatable, safe automation outputs.

How do I automate code reviews across git branches using Codex?▼

Automate code reviews across git branches using Codex by executing codex exec review --base main --full-auto. This non-interactive pattern applies headless analysis to compare branches, commits, and working trees for reliable CI/CD integration.

When should I use base, uncommitted, or commit reviews in Codex automation?▼

Use base, uncommitted, or commit reviews in Codex automation based on your target scope: base compares against a branch, uncommitted analyzes the working tree, and commit targets specific changes. This skill provides decision trees to select the correct review mode.

Can I use Codex CLI for headless code analysis in CI pipelines without user input?▼

Yes, you can use Codex CLI for headless code analysis in CI pipelines without user input by leveraging codex exec and codex review. This skill enables non-interactive execution with stdin prompts and session resume for fully automated, prompt-driven workflows.

Why do my Codex CLI automated workflows fail or produce inconsistent results?▼

Codex CLI automated workflows fail or produce inconsistent results when lacking explicit usage patterns and version checks. This skill enforces structured command semantics and non-interactive execution rules to ensure safe, repeatable automation across branches and commits.
