What it does

Visual Style is an agent skill from calesthio/OpenMontage. Create, extract, and apply portable visual design systems via visual-style.md files. Use when: (1) Creating a visual-style.md design system from scratch, (2) Extracting a visual style from a website URL, video, or PDF brand guide, (3) Applying a visual style to HeyGen videos, HTML slides, Figma, or paper.design, (4) Browsing the gallery of pre-built visual styles (Swiss, Saul Bass, Game Boy, etc.), (5) User mentions "visual style", "design system", "brand style", or "style guide", (6) Styling a HeyGen video with…

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including reference files (for example `references/connectors/figma.md`, `references/connectors/heygen-video-agent.md` and `references/connectors/html-slides.md`).

It sits in Frontend & Design, covering UI design, Slides and decks and Logo and visual identity. It works with HeyGen and Figma. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is AGPL-3.0.

When your agent uses it

Creating a visual-style.md design system from scratch
Extracting a visual style from a website URL
PDF brand guide
Applying a visual style to HeyGen videos

Example prompts

“visual style”
“design system”
“brand style”
“/visual-style”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

Gather vibe — Ask about mood, era, references, inspiration
Define colors — Primary (2+), accent, neutrals with hex values and roles
Set typography — Display, body, caption families + weight/style rules
Layout & motion — Grid system, transitions, pacing
Generate — Output complete visual-style.md using references/templates/minimal.visual-style.md or references/templates/full.visual-style.md
Preview — Show a small HTML swatch or describe the visual result
Optionally apply — Ask if user wants to use it with a connector

What it can do on your machine

Read from SKILL.md and the folder at commit 9327439. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Visual Style loads about 1.5k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 140 tokens; SKILL.md has 490 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~140
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~21k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Visual Style

Create, extract, and apply portable visual design systems. A visual-style.md file defines colors, typography, layout, motion, and mood in one file that any AI tool can consume.

Quick Reference

Mode	Trigger	What it does
Create	"Create a visual-style.md for..."	Build a style from scratch via guided prompts
Extract	"Extract a visual-style.md from [URL/image/video]"	Analyze a source and generate a style file
Apply	"Apply this visual-style.md to [tool]"	Use a style with a specific connector
Gallery	"Show me available visual styles"	Browse and use example styles

Default Workflow

Create

Gather vibe — Ask about mood, era, references, inspiration
Define colors — Primary (2+), accent, neutrals with hex values and roles
Set typography — Display, body, caption families + weight/style rules
Layout & motion — Grid system, transitions, pacing
Generate — Output complete visual-style.md using references/templates/minimal.visual-style.md or references/templates/full.visual-style.md
Preview — Show a small HTML swatch or describe the visual result
Optionally apply — Ask if user wants to use it with a connector

Questions to batch:

What's the vibe? (mood keywords, era, references)
Any specific colors? (or derive from the vibe?)
Typography preference? (clean, editorial, technical, playful?)
What tool will you use this with? (HeyGen, slides, paper.design, Figma?)

Extract

Receive source — URL, image, video, or PDF
Load extractor — Read the appropriate extractor reference file
Analyze — Identify colors, typography, layout, motion, mood
Generate — Output complete visual-style.md with source_url set
Validate — Ensure all required fields are present

Apply

Read the style — Load the visual-style.md file
Ask which connector — Or detect from context
Load connector — Read the appropriate connector reference file
Transform — Map style fields to tool-specific format
Generate output — Produce tool-ready instructions or code

Show full SKILL.md (206 more words)Show less

Gallery

List styles — Show available styles from references/gallery/
Preview — Describe the selected style's visual character
Load — Read the full visual-style.md
Apply — Use with a connector

Format Quick Reference

Required fields

yaml

name: "Style Name"
version: "1.0"
style_prompt_short: "1-2 sentence elevator pitch"
style_prompt_full: "Detailed generation prompt — THE most important field"
colors:
  primary:
    - name: "Color Name"
      hex: "#000000"
      role: "how this color is used"

style_prompt_full is king. If a tool can only read one field, it reads this one. Everything else is structured data for tools that want finer control.

style_prompt_full is king — Always usable as a standalone generation prompt
One style, one file — No multi-style bundling
Assets are URLs — Never embed binary data
Show, don't tell — Generate previews when creating styles
Opinionated defaults, flexible extensions — Core schema is fixed; x_* for tool-specific config

Questions about Visual Style

What does Visual Style do?

Create, extract, and apply portable visual design systems via visual-style.md files. Visual Style is an agent skill from calesthio/OpenMontage.md files.

When should I use Visual Style?

Visual Style fits situations like: creating a visual-style.md design system from scratch; extracting a visual style from a website URL; PDF brand guide; applying a visual style to HeyGen videos.

How do I install Visual Style in Claude Code?

Run `npx skills add calesthio/OpenMontage --skill visual-style -a claude-code`. Or copy the skill folder (.agents/skills/visual-style in calesthio/OpenMontage) into .claude/skills/visual-style in your project. Claude Code loads it when a task matches its description.

How do I install Visual Style in Codex?

Run `npx skills add calesthio/OpenMontage --skill visual-style -a codex`. Or copy the skill folder (.agents/skills/visual-style in calesthio/OpenMontage) into .agents/skills/visual-style in your project. Codex loads it when a task matches its description.

Can I use Visual Style in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add calesthio/OpenMontage --skill visual-style -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/visual-style, .gemini/skills/visual-style, .github/skills/visual-style and .opencode/skills/visual-style in your project.

What does Visual Style need to run?

SKILL.md names no scripts, command-line tools or credentials: Visual Style is instructions for the agent only.

Does Visual Style access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Visual Style safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Visual Style use?

Visual Style is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Visual Style use?

About 1.5k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 19k tokens, read only when the agent opens those files.

What are the alternatives to Visual Style?

Skills that share tags, products or a category with Visual Style: Cc Design (ZeroZ-lab/cc-design, 827 stars), Design (Ohh-889/skyroc, 795 stars), Baoyu Design (DejavuMoe/Smoji, 114 stars) and Brand Agency (glebis/claude-skills, 389 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Visual Style?

calesthio (a GitHub user) maintains it in calesthio/OpenMontage, which has 65,101 GitHub stars. The repository holds 41 skills in this directory. The repository was last updated on October 3, 2026.

Source: calesthio/OpenMontage on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
