Frequently Asked Questions about codex-cli-runner

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run the Codex CLI non-interactively for automated tasks?▼

You can run the Codex CLI non-interactively by using a runner to execute custom prompts without an interactive session. This approach handles file-based prompts and writes the execution results directly to an output file.

What's the best way to automate prompt execution with the Codex CLI?▼

Automating prompt execution with the Codex CLI is best handled by passing file-based prompts to a non-interactive runner. This method processes custom tasks and automatically saves the generated output to a specified file.

Does non-interactive Codex CLI execution support system instructions from files?▼

Yes, non-interactive Codex CLI execution supports loading both custom prompts and system instructions from files. This allows you to fully configure the task context before running the automated execution.

Why does non-interactive prompt execution fail with transient errors?▼

Transient errors during non-interactive prompt execution occur due to temporary network or service issues. You can resolve these by using a runner that implements retries with exponential backoff to handle the failures automatically.

Do I need the Codex CLI installed to use a non-interactive runner?▼

Yes, you must have the Codex CLI installed and properly configured on your system to use a non-interactive runner. The runner acts as a wrapper that executes the CLI commands for your custom prompts.

Can I output Codex CLI results to a specific file for later analysis?▼

Yes, you can output Codex CLI results to a specific file for later analysis. The non-interactive execution runner writes the generated task output directly to a file path you specify.
