Codex Image — OAuth Image Generation

What it does

Provides a reproducible flow for generating images through the Codex CLI's built-in image_gen tool (gpt-image-2) using Codex OAuth authentication. Automates auth checks, argument parsing (size, quality, count, output), safe timestamped file naming, and instruction to display generated images via the Read tool. Includes error handling for auth expiration, model access, timeouts, and rate limits.

When to use it

Use this skill when you want to create images from prompts without a direct OpenAI API key, particularly in interactive developer workflows where Codex CLI is available and OAuth login is preferred. Useful for prototyping assets, adding generated imagery to projects, or automating image creation in local developer environments.

What's included

• Scripts: no separate scripts detected (has_scripts=false) but the skill contains detailed CLI commands and flow examples
• References: links to expected Codex behavior and example file paths are included in the skill body
• Instructions: step-by-step checks for codex installation/login, argument parsing, generation command, result display, and follow-up guidance.

Compatible agents

Developer-facing agents with Bash and filesystem access (Codex/Copilot/Claude Code style) that can run codex exec or surface instructions to a user.
