rails-upgrade-6-to-7

Fine to try.

By MadBomber/experiments (GitHub) · other · 11 stars · scanned at commit 8139ff6

Upgrade a Ruby on Rails app from 6.x to 7.x — dual-boot via next_rails, the Zeitwerk autoloader transition (was already in 6.0 but became mandatory), Sprockets-to-importmap or jsbundling decision, Hotwire arriving, encrypted attributes via Active Record Encryption (7.0+), the version hop sequence. Use when the user is upgrading from Rails 6 to 7, mentions Zeitwerk, Webpacker removal, importmap-rails, Hotwire migration, encrypted attributes, or asks how to get off Rails 6.

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-6-to-7' ] || [ -L ~/.agents/skills/'rails-upgrade-6-to-7' ]; then echo 'A skill folder named rails-upgrade-6-to-7 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 "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/17-rails-upgrade-6-to-7' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/17-rails-upgrade-6-to-7' ~/.agents/skills/'rails-upgrade-6-to-7' && 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-6-to-7' ~/.claude/skills/'rails-upgrade-6-to-7' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
