Fine to try. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

Upgrade a Ruby on Rails app from Rails 7.x to Rails 8.0 — dual-boot via next_rails, the deprecation-fix loop, Solid Queue / Solid Cache / Solid Cable adoption choices, Propshaft over Sprockets, the new authentication generator vs existing Devise, Kamal 2 deployment cutover, gem compatibility matrix, the version hop sequence. Use when the user is upgrading Rails to 8, asks about Rails 8 migration, mentions next_rails, dual booting, Gemfile.next, Solid Queue migration, Sprockets to Propshaft, or …

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'rails-upgrade-7-to-8' ] || [ -L ~/.agents/skills/'rails-upgrade-7-to-8' ]; then echo 'A skill folder named rails-upgrade-7-to-8 already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/16-rails-upgrade-7-to-8' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/16-rails-upgrade-7-to-8' ~/.agents/skills/'rails-upgrade-7-to-8' && 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/'rails-upgrade-7-to-8' ~/.claude/skills/'rails-upgrade-7-to-8' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
