Installation

Requirements

• VS Code 1.93+
• A chat language model provider — e.g. GitHub Copilot, or any provider that exposes VS Code’s Language Model API. Skiller runs your skills through whatever model VS Code chat offers; it does not ship a model of its own.
• MCP servers configured in VS Code — optional, only needed for tool steps and tool-using llm steps.
• Node.js (LTS) + npm — only if you install from source (below); not needed for the Marketplace install.

From the Marketplace

ext install tivaliy.skiller

Or search for Skiller in the Extensions view, or open the Marketplace listing.

From source

git clone https://github.com/tivaliy/skiller.git
cd skiller
npm install
npm run package
code --install-extension skiller-*.vsix

Check a model is available

After installing, open the Chat view and run:

@skiller /models

If one or more models are listed, you’re ready to go. If it’s empty, set up a provider first — for example, sign in to GitHub Copilot — then run /models again.

The model you pick in the chat model dropdown is the one skills use. Skills can also declare their own model in skill.yaml; for how that interacts with your dropdown choice, see Use & override models.
