# System check

If you build software, Foxora checks that the tools your agents reach for are installed and current — and installs the missing ones for you, one click at a time.

## What it checks

Foxora probes your machine for common developer tools — like Node, Git, and Bun — and shows each one’s status:

- Installed — green check, with the detected version.
- Update available — yellow, with the minimum version it wants.
- Not installed — grey, with an install button.

## Installing what's missing

- 01Pick a package managerChoose the fallback package manager Foxora should use — Bun (recommended), npm, yarn, or pnpm. Projects with their own lockfile keep using it; this is just the default.
- 02Install or updateClick Install or Update next to any tool. A spinner shows progress, and if a command fails, the failing command is shown so you can run it yourself.

> Run it again laterYou can skip the check during onboarding and revisit your toolchain any time. A clean toolchain means agents can build, test, and run without hitting a missing-binary wall mid-task.
