synsema

Synsema — the programming language for AI agents — installed from npm. This package puts the native synsema binary (Rust, single static executable) on your PATH; it is the same binary as the GitHub release, wrapped for the Node ecosystem.

npm i -g synsema          # global: `synsema run app.syn`
npx synsema run app.syn   # or per project, no global install
npx synsema init          # scaffold a project (hello.syn, .env.example, .gitignore)

How it works: synsema depends on one platform package per target (@synsema/cli-linux-x64, @synsema/cli-darwin-arm64, @synsema/cli-darwin-x64, @synsema/cli-win32-x64) as optionalDependencies with os/cpu filters, so npm installs only the binary for your machine. bin/synsema.js is a 40-line launcher that runs it with your arguments — no postinstall, no downloads at install time, works with --ignore-scripts and mirrored registries.

Updating: npm i -g synsema@latest (the binary's own synsema update notices it was installed by npm and tells you the same). Other install paths — curl -fsSL https://synsema.com/install.sh | sh, PowerShell, Docker, the WebAssembly artifacts and the embeddable @synsema/wasm — are in the docs.
