codex-imagegen

Use this skill for raster image generation requests. Do not use it for SVG, vector-only, or code-native assets unless the user explicitly wants a raster export.

The extracted extension implementation is kept with this skill under scripts/ for reference and future edits:

• scripts/index.ts — tool registration/background task orchestration
• scripts/generate.ts — standalone CLI runner/smoke test for these scripts
• scripts/codex-exec.ts — Codex backend command construction
• scripts/icon.ts — icon batch detection, prompt rules, slicing script
• scripts/transparent.ts — transparent-background detection/conversion script
• scripts/prompts/ — prompt snippets/instructions
• scripts/utils.ts — path, slug, MIME, shell helpers

Standalone script smoke test

You can run the extracted implementation without loading the pi extension:
