What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'msbuild' ] || [ -L ~/.agents/skills/'msbuild' ]; then echo 'A skill folder named msbuild already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/microsoft/testfx' "$d" && git -C "$d" checkout --quiet '8dd78e1347417e400c3ef8d786059a8bb346162f' -- '.agents/skills/msbuild' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/msbuild' ~/.agents/skills/'msbuild' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'msbuild' ~/.claude/skills/'msbuild' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
