Designer-Grade Poster Skill

A portable Agent Skill that turns any text into production-ready, designer-grade posters.

The input can be structured information you’ve already organized or free-form writing — it analyzes the source content, organizes the information automatically, recommends a visual style, writes a polished image prompt, and then calls an image-generation skill or tool already available to the host agent to render the final poster.

---

Features

• Content analysis - extracts headline, CTA, metadata, visual subject, tone, and information priority from markdown or raw text.
• Automatic composition - organizes information from the content, content density, visual subject, channel, and aspect ratio.
• 20 visual styles - users can specify an aesthetic direction; when unspecified, options are recommended based on your content.
• Multi-language - creates posters in Chinese, English, Japanese, and other languages.
• Multi-aspect - supports 1:1, 4:5, 2:3, 3:4, 9:16, and 16:9.
• Full audit trail - leaves a source.md -> analysis.md -> structured-content.md -> prompts/poster.md -> poster.png trail for review and iteration.

---

Requirements

The host agent must be able to call at least one image-generation capability.

Use with Claude Code

1. Install

Clone the complete repository into your Claude Code skills directory:

git clone https://github.com/howardz27/poster-generator-skill.git \
  ~/.claude/skills/poster-generator

Make sure Claude Code also has access to an image-generation skill or tool described in Requirements, then restart Claude Code so the skill is discovered.

2. Invoke

Describe what you want in natural language and paste the content directly:

/poster-generator Make me a vertical poster for this event, in English.
I. Event Basics
Dates: June 26–28, 2026
...

Or invoke the skill without arguments and paste the content:

/poster-generator

Claude Code analyzes the content, organizes the information automatically, proposes several visual styles, asks for one combined confirmation, and then generates the poster with an available image-generation capability.

You can state your preferred style (20 options listed below), aspect ratio (1:1, 4:5, 2:3, 3:4, 9:16, or 16:9), and language in natural language, e.g. “use neo-brutalist, 9:16 portrait, in English.” When not specified: style is auto-recommended (3–5 options for you to confirm); aspect ratio defaults to 2:3; language defaults to the source content’s language.
