SkyNot

SkyNot is an open-source npx tool from the tarsgate organization that installs the Pi coding agent on a local Linux or macOS system under its own dedicated unix user. Running npx skynot guides the user through setup, asks for sudo at each step that needs it, and explains what it is doing. The latest release listed is v0.0.755.

What It Is

SkyNot is a CLI installer and launcher generator for Pi (pi-coding-agent). Instead of a cloud deployment or guardrail extensions, it relies on the unix user model: Pi runs as a separate user with its own home directory where its git repositories live. The project describes this as a middle path between complex cloud deploys and plugins that may give a false sense of security.

How the Setup Works

The installer checks for wget, creates an aidev user and an aiteam group, and adds both the aidev user and the current user to that group. It writes a sudoers file so the current user can impersonate aidev without a password, and configures umask and ACLs so both users can share files. It then downloads Pi into the aidev home, adds the agent's binary directory to the aidev user's PATH, configures git for shared repositories, and creates a Work directory owned by aidev:aiteam. Finally it creates a launcher script at $HOME/bin/spi.

Launch Checks and Options

Each time spi runs, it verifies the current directory is inside ~aidev/Work, checks that the user's directories are not readable or writable by aidev, and offers to shield any that are, before launching Pi as aidev. Flags cover model credentials, git identity, SSH key copying, npm-based installation, a paranoid mode that does not cache the sudo password, updating Pi, verbose output, and a destroy option that removes the user, its data, and the group.

Requirements

The README lists Linux or macOS, Node.js v22.x, npx, git 2.46 or newer, and the setfacl command on Linux.
