Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Upgrade a Ruby on Rails app from 5.x to 6.x — dual-boot via next_rails, Zeitwerk autoloader transition from Classic, Webpacker becoming default, ActionMailbox + ActionText shipping, parallel testing, multi-database support, the version hop sequence. Use when upgrading from Rails 5 to 6, mentions Zeitwerk, autoload paths, Classic to Zeitwerk migration, Webpacker, or asks how to leave Rails 5.

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-5-to-6' ] || [ -L ~/.agents/skills/'rails-upgrade-5-to-6' ]; then echo 'A skill folder named rails-upgrade-5-to-6 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 "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/18-rails-upgrade-5-to-6' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/18-rails-upgrade-5-to-6' ~/.agents/skills/'rails-upgrade-5-to-6' && 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-5-to-6' ~/.claude/skills/'rails-upgrade-5-to-6' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
