Computer Setup

This is a sanity check, not the primary install path. Onboarding runs the install.sh one-liner before the agent session ever opens, and that script already installs the dev tools (and the cofounder skills). So by the time a session exists, a package manager, mise, podman, and GH CLI should all be present. This skill verifies that — and if a tool is somehow missing, it points the user back at the same one-liner to repair the install. Idempotent — safe to re-run.

1. Detect platform

uname -s 2>/dev/null || echo Windows

• Darwin → follow macOS / Linux (one-liner)
• Linux → follow macOS / Linux (one-liner)
• MINGW64_NT* / MSYS_NT* or similar → follow Windows
