ArtCraft Agent Skills

Thirteen evidence-verified agent skills — plain SKILL.md files following the agentskills.io standard — that teach AI coding agents to drive the ArtCraft creative suite. Built for Claude Code, OpenAI Codex & ChatGPT desktop, OpenCode, Devin, CommandCode, ZCode, Google Antigravity and Gemini CLI.

ArtCraft is the open-source, pure-Rust, clean-room creative suite from the storytold organization (Photoshop-, Illustrator-, Premiere-, Lightroom-, Acrobat-, After Effects-, InDesign-, Figma-, Word-, Pro Tools-, PowerPoint-, AutoCAD- and Excel-style apps, all installable via the ArtCraft Launcher).

Each skill teaches an AI coding agent what one app can really do, what it cannot do yet, and how to drive it correctly — through the app's first-class automation surface (headless CLI, MCP (Model Context Protocol) server, localhost JSON control channel) rather than blind GUI automation. Mention an app or one of its file formats — .psd, .pptx, .xlsx, .docx, .dxf — and the matching skill triggers.

Works with: any agent that implements the agentskills.io SKILL.md standard — Claude Code, OpenAI Codex & ChatGPT desktop, OpenCode, Devin, CommandCode, ZCode, Gemini CLI, Google Antigravity and more. One command per agent:

The SKILL.md files are plain Markdown + shell, so any agent that can read files can use them. Full per-agent options are under Install below.

Install

Clone once, then pick the target that matches your agent:

git clone https://github.com/midasmatterhorn/artcraft-skills.git
cd artcraft-skills

One paste: let your coding agent do it

Copy this into your agent (Claude Code, Codex, ChatGPT, OpenCode, Devin, CommandCode, ZCode, or any coding agent):

Clone https://github.com/midasmatterhorn/artcraft-skills.git into a temporary directory, then install the skills for the agent I'm using now:
- Windows: run `.\install.ps1`; if you are Claude Code use `.\install.ps1 -Claude`, if you are OpenCode use `.\install.ps1 -OpenCode`, if you are Gemini CLI use `.\install.ps1 -Gemini`, if you are Antigravity use `.\install.ps1 -Antigravity`, and add `-Force` to overwrite existing installs.
- OpenCode (macOS/Linux): run `bash install.sh --opencode`, which installs into ~/.config/opencode/skills/.
- Claude Code (macOS/Linux): run `bash install.sh --claude`, which installs into ~/.claude/skills/.
- Gemini CLI (macOS/Linux): the default install works — Gemini CLI scans ~/.agents/skills/ too; use `bash install.sh --gemini` to scope it to ~/.gemini/skills/ instead.
- Google Antigravity (macOS/Linux): run `bash install.sh --antigravity`, which installs into ~/.gemini/config/skills/, Antigravity's global skills directory.
- Everyone else (OpenAI Codex, ChatGPT desktop, ZCode, Devin, CommandCode, or any other SKILL.md-standard agent): run `bash install.sh`; the default target is ~/.agents/skills/, which those agents scan natively.
Verify the install: all 13 skill directories must be present under the target directory, each containing SKILL.md and agents/openai.yaml. Print the target directory you used.
Then tell me to restart my agent session so the new skills are discovered.

Works as-is in Claude Code, Codex, OpenCode, Devin, CommandCode, ZCode, Gemini CLI and Antigravity; any SKILL.md-standard agent can follow it too.

Standard agents (Codex, ChatGPT, ZCode, Devin, CommandCode)

bash install.sh            # default target: ~/.agents/skills/

~/.agents/skills/ is the shared directory that OpenAI Codex, ChatGPT desktop, ZCode, Devin, CommandCode and Gemini CLI all scan natively (ZCode also reads ~/.zcode/skills/; CommandCode also reads ~/.commandcode/skills/; Gemini CLI treats ~/.agents/skills/ as an alias for ~/.gemini/skills/ and prefers the alias within that tier). Every skill ships an agents/openai.yaml sidecar so the Codex/ChatGPT UI shows the proper display name and description. CommandCode users can alternatively install natively with cmd skills add midasmatterhorn/artcraft-skills --global.

Invoke a skill explicitly with $photocraft (or $wordcraft, …), or let implicit triggering fire when you mention an app or an extension like .psd, .pptx, .xlsx, .docx or .dxf. If a freshly installed skill doesn't show up, restart your agent.

Claude Code

bash install.sh --claude   # copies all 13 skills into ~/.claude/skills/

--claude targets Claude Code's user-scoped ~/.claude/skills/ directory (a project-scoped .claude/skills/ works the same way). Prefer symlinks when you want git pull to keep skills current:

ln -s "$PWD/photocraft" ~/.claude/skills/photocraft   # repeat for each skill

OpenCode

bash install.sh --opencode   # copies all 13 skills into ~/.config/opencode/skills/

--opencode targets OpenCode's global skills directory ~/.config/opencode/skills/, where they are discovered for every project. To scope skills to a single project instead, symlink them into that project's .opencode/skills/ directory:

ln -s "$PWD/photocraft" .opencode/skills/photocraft   # repeat for each skill

As with Claude Code, symlinks mean git pull keeps the installed skills current.

Gemini CLI

bash install.sh --gemini   # copies all 13 skills into ~/.gemini/skills/

--gemini targets Gemini CLI's user-scoped ~/.gemini/skills/ directory. Gemini CLI also scans the shared ~/.agents/skills/ (preferring it within the same tier), so the default install already works — use --gemini only when you want the skills scoped to Gemini alone. For a single project, symlink into that project's .gemini/skills/ (or its .agents/skills/ alias):

ln -s "$PWD/photocraft" .gemini/skills/photocraft   # repeat for each skill

Google Antigravity

bash install.sh --antigravity   # copies all 13 skills into ~/.gemini/config/skills/

--antigravity targets Antigravity's global skills directory ~/.gemini/config/skills/, discovered across the Antigravity app, IDE and CLI. For a single project, symlink into the repo's .agents/skills/ directory, which Antigravity scans at workspace level:

ln -s "$PWD/photocraft" .agents/skills/photocraft   # repeat for each skill

claude.ai / Claude Desktop

Zip a skill folder and upload it via Settings → Capabilities → Skills:

cd artcraft-skills && zip -r photocraft.skill.zip photocraft

Windows (PowerShell / WSL)

Native Windows: after cloning, run the PowerShell installer (install.ps1):

powershell -ExecutionPolicy Bypass -File .\install.ps1   # or .\install.ps1 in an existing PowerShell session

-Claude targets Claude Code's %USERPROFILE%\.claude\skills, -OpenCode targets OpenCode's %USERPROFILE%\.config\opencode\skills, -Gemini targets Gemini CLI's %USERPROFILE%\.gemini\skills and -Antigravity targets Antigravity's %USERPROFILE%\.gemini\config\skills; the default is %USERPROFILE%\.agents\skills (scanned natively by Codex, ChatGPT desktop, ZCode, Devin, CommandCode and Gemini CLI on Windows), and -Force overwrites existing installs.

On WSL or Git Bash the bash installer works unchanged (bash install.sh, --claude, --opencode, --gemini, --antigravity) — no need for install.ps1 there. The skill folders are plain Markdown; only the paths inside the docs are written macOS-first (see the Platforms note below).

Manual / other agents

Copy or symlink any skill folder into the directory your agent reads — the format is the portable SKILL.md standard, so nothing here is Claude-, Codex- or OpenCode-specific. install.sh also accepts --force to overwrite existing installs (e.g. bash install.sh --force).

Skills trigger automatically when you mention an app or its file formats (.psd, .pptx, .xlsx, .docx, .dxf, .deckcraft, .scraft, …), or force one in-session with /photocraft (Claude Code) or $photocraft (Codex).

Platforms: Installing works the same on macOS, Linux and Windows (targets above), and the SKILL.md format itself is OS-agnostic. The skill bodies, however, were authored against macOS app installs: launch and paths sections cite /Applications/<App>.app and ~/Library/Application Support/.... The apps ship native Windows and Linux builds with the same CLI/MCP/command surfaces (binary names gain .exe on Windows; config and log paths move under %APPDATA%/%LOCALAPPDATA% on Windows and ~/.local/state etc. on Linux) — so treat the macOS paths as the conceptual location and check the app's own docs/output for exact equival
