AI image generation: Gemini and Nano Banana backends; single/series/batch workflows with prompt-to-disk.
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
# image-gen
Backend-agnostic image generation: single images, series with anchor-chain consistency, batch pipelines. Two backends: Gemini (API) and Nano Banana (local scripts with post-processing).
## Deep References
| Signal | Load | Content |
|---|---|---|
| Gemini backend selected | `references/backends/gemini.md` | Models, env vars, flag table, examples, error codes |
| Nano Banana needed (post-processing, series, JSON batch, style-match) | `references/backends/nano-banana.md` | Subcommands, flags, aspect ratios, prompt patterns by asset type |
## Phase 1: Detect Backend
```bash
python3 skills/content/image-gen/scripts/detect-backend.py
```
- `gemini` -- load `references/backends/gemini.md`
- `ask` -- no key found; ask the user to set `GEMINI_API_KEY`
**Gate**: backend confirmed.
## Phase 2: Write Prompt Files
Write all prompts to disk before any API call. Prompt files are the generation record and anchor-chain input for series.
File naming: single `prompts/YYYY-MM-DD-{slug}.md`, series `prompts/{series-name}-01.md` through `-NN.md`.

How to install
mdr add notque/vexjoy-agent/image-gen@sha256:a32cf71cba3ed7daThe line at the top of this page pins the label git:20260919.28d30f9, 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.
