Prerequisites

Tools that the GravionLabs skills and their scripts depend on. Check your machine with the repo-local check-prerequisites skill:

pwsh .github/skills/check-prerequisites/scripts/Check-Prerequisites.ps1          # core tools
pwsh .github/skills/check-prerequisites/scripts/Check-Prerequisites.ps1 -Full    # plus optional tools
pwsh .github/skills/check-prerequisites/scripts/Check-Prerequisites.ps1 -AutoInstall

-AutoInstall uses winget (Windows), brew (macOS) or apt-get / dnf (Linux).

Core (every group)

Tool	Version	Why
PowerShell	7.4+	All skill scripts are pwsh scripts. detect-techstack has a manual fallback, but scaffolding and report scripts need it.
Git	2.40+	Branching, commits, diffs in every workflow skill
Node.js	22+	npx skills installs and updates the skills

Install PowerShell:

winget install Microsoft.PowerShell        # Windows
brew install powershell/tap/powershell     # macOS
# Linux: https://learn.microsoft.com/powershell/scripting/install/install-linux

Per group

Group	Tools
github, delivery	GitHub CLI gh 2.40+, authenticated (gh auth status). github-release installs git-cliff itself when the changelog is generated.
ts	Node.js 22 LTS, npm; pnpm for ts-pnpm-workflow (the skill installs it)
ng	Node.js 22 LTS, Angular CLI 21+ (npm i -g @angular/cli)
py	Python 3.14, uv
dotnet	.NET SDK 10 (libraries multi-target net10.0;net9.0;net8.0)
shared, skill-tooling	PowerShell and Git only

Install the runtimes with your platform's package manager, for example:

winget install OpenJS.NodeJS.LTS GitHub.cli Microsoft.DotNet.SDK.10 Python.Python.3.14 astral-sh.uv   # Windows
brew install node gh dotnet-sdk python@3.14 uv                                                        # macOS

Optional

jq, yq, curl and ast-grep are checked by -Full. A few scripts use jq and curl when present; none of the current skills require yq or ast-grep.

Language servers for Copilot CLI are described in LSP configuration.
