# /codex-imagegen — image generation via the local Codex CLI (no API key) Generate or edit raster images by driving the **already-installed, already-logged-in** OpenAI Codex CLI and triggering its **built-in `image_gen` tool**. This piggybacks on the user's **ChatGPT Plus/Pro session tokens** that Codex stores in `auth.json` — there is **no `OPENAI_API_KEY`** and **no manual HTTP / internal-route work**. The image model under the hood is OpenAI's `gpt-image` (gpt-image-2). ## How this actually works (read once) - Codex ships two image paths. **(1) the built-in `image_gen` tool** — server-side, runs on whatever auth Codex has (ChatGPT login *or* key), **needs no key**. **(2) a Python fallback CLI** (`image_gen.py`) — needs `OPENAI_API_KEY`. **This skill uses path (1) only** and must steer the agent away from path (2). - We invoke it through `codex exec "<prompt>"` (non-interactive). The prompt instructs the Codex agent to call the built-in `image_gen` tool and generate N images. - **Where files land:** the built-in tool has **no path argument** — it writes to `$CODEX_HOME\generated_images\<session-id>\ig_*.png`. The agent's own "now copy it to your folder" step is **unreliable and frequently hallucinated** (it prints `DONE` + a fake path while the real PNG sits in `generated_images`). So **the helper script does the copy itself**: it snapshots `generated_images` before the run, finds the new file after, and copies it into `-OutDir` with a friendly name. Ne
