Generates professional designer-grade posters, flyers, campaign visuals, event posters, and product posters. Use when the user asks for 海报, poster, flyer, campaign visual, event poster, product poster, promotional visual, or high-end marketing key visual.

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

# Poster Generator

Choose from 20 visual styles. The skill organizes the poster composition automatically from the content, channel, and aspect ratio.

This skill creates polished, modern, practical posters with production-ready image prompts.

## Usage

```bash
/poster-generator path/to/content.md
/poster-generator path/to/content.md --style swiss-editorial
/poster-generator path/to/content.md --aspect 4:5 --lang zh
/poster-generator "新品发布会，6月30日，上海" --style luxury-minimal
/poster-generator  # then paste content
```

## Options

| Option | Values |
|--------|--------|
| `--style` | 20 options, default: swiss-editorial |
| `--aspect` | 1:1, 4:5, 2:3, 3:4, 9:16, 16:9; default: 2:3 |
| `--lang` | en, zh, ja, etc.; default: source language |
| `--renderer` | name of an installed image-generation skill or MCP tool to use for rendering (e.g. `image-gen`, `baoyu-image-gen`). Default: auto-discovered at runtime. |
| `--backend` | passed through to the chosen renderer when it supports sub-backends (e.g. `jimeng`, `banana`, `gpt-image-2` for `image-gen`). Default: renderer's own default. |
| `--quality` | 1K, 2K, 4K where the renderer supports it |

How to install

The exact contents, by fingerprint
mdr add howardz27/poster-generator-skill/poster-generator@sha256:5c1df2ce51ad0635

The line at the top of this page pins the label git:20260924.fa2a40b, 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.
