Automatically updates a codebase to a new language version, framework version, or library update while ensuring all tests still pass.

What this skill can do

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

if [ -e ~/.agents/skills/'test-guided-migration-assistant' ] || [ -L ~/.agents/skills/'test-guided-migration-assistant' ]; then echo 'A skill folder named test-guided-migration-assistant already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ArabelaTso/Skills-4-SE' "$d" && git -C "$d" checkout --quiet '4f38503747e0617504bce5329283ef837d375c09' -- 'skills/test-guided-migration-assistant' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/test-guided-migration-assistant' ~/.agents/skills/'test-guided-migration-assistant' && 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/'test-guided-migration-assistant' ~/.claude/skills/'test-guided-migration-assistant' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
