Generates images and polished raster art (logos, mascots, hero images, icons, characters, sprite sheets, illustrations, product mockups) by driving Codex CLI's $imagegen skill. This is the default image generator, use it for any request to generate or create an image or visual asset, including "generate an image", "create a hero image", "make a mascot", "design a logo", "draw an icon", "generate a sprite sheet", or "make an illustration". Requires the `codex` CLI installed and authenticated…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex Imagegen: Illustrated Asset Generation via Codex CLI Generate polished, professionally-illustrated raster art (mascots, hero images, logos, sprite sheets, product mockups) by driving Codex CLI's `$imagegen` skill. Use this instead of hand-drawing shapes in SVG/CSS/SwiftUI when the asset needs to look designed, not programmatically constructed. ## Scope check (do this first) This skill wraps a multi-minute, credit-billed Codex run and is the default handler for image-generation requests: - **Architecture/flow/sequence diagram** → tell the user to use `docs-diagram` instead and stop here. - Otherwise, continue: the cost gate in Phase 2 decides whether to confirm before running. ## Ground rules - **Single-quote the whole prompt.** `$imagegen` must reach `codex` literally, not be shell-expanded: a double-quoted or unquoted prompt containing `$imagegen` breaks. - **Never fabricate a model ID.** `gpt-6-sol` (agent) and GPT Image 2.5 Sunburst (`gpt-image-2.5-sunburst`, images) are this recipe's known-good defaults at time of writing; if `codex` rejects one, check `codex --version`/`codex exec --help` for a current one rather than guessing a replacement. …

How to install
mdr add mgiovani/cc-arsenal/codex-imagegen@sha256:8674e90e80e6031bThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
