Single-image generation skill for posters, key art, and editorial illustrations. Defaults to gpt-image-2 but is provider-agnostic — the same workflow drives Flux, Imagen, or Midjourney via the active upstream tooling. Output is one or more PNG/JPEG files saved to the project folder.
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 Poster Skill Produce **one** finished image asset per turn unless the user asks for variations. Image generation rewards a tight, structured prompt — your job is to assemble that prompt from the user's brief, then dispatch. ## Resource map ``` image-poster/ ├── SKILL.md ← you're reading this └── example.html ← what the resulting card looks like in Examples ``` ## Workflow ### Step 0 — Read the project metadata The active project carries `imageModel`, `imageAspect`, and (optional) `imageStyle` notes. Use them as the upstream model + canvas + style anchor. When a value is not provided, infer a safe default from the brief and media contract. Ask only when the choice would materially change the requested result and no safe default can be inferred. ### Step 1 — Compose the prompt Plan in this exact order before calling any tool: 1. **Subject + composition** — what is in the frame, where, at what scale; eye-line and crop. 2. **Lighting + mood** — natural / studio / moody; warm / cool; key plus rim plus fill; time of day if outdoor. 3. **Palette + textures** — hex anchors when the user gave a brand …

How to install
mdr add muselinn/musepi/image-poster@sha256:20769996ade6c165The line at the top of this page pins the label git:20261007.83a0e3e, 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.
