Use when the user runs /ruby-upgrade-toolkit:audit or asks to audit their project before an upgrade, find what will break, check gem compatibility, or assess the scope of an upgrade. Read-only — never modifies files. Accepts ruby:X.Y.Z and optional rails:X.Y arguments.
Use when the user runs /ruby-upgrade-toolkit:fix or asks to apply upgrade fixes, bump Ruby/Rails versions, fix deprecations, fix RSpec failures after upgrading, or fix RuboCop issues. Accepts `next` (read target from the task list) OR explicit ruby:X.Y.Z, optional rails:X.Y, and optional scope:path arguments. Applies all changes, iterates until green, verifies, prompts for commit, and ticks off the matching task.
Use when the user runs /ruby-upgrade-toolkit:plan or asks to plan a Ruby or Rails upgrade, generate an upgrade roadmap, or understand what phases are involved in bumping versions. Accepts ruby:X.Y.Z and optional rails:X.Y arguments. Produces a phased, project-specific upgrade plan with estimates AND creates a TodoWrite task list that /fix next and /upgrade consume.
Use when the user runs /ruby-upgrade-toolkit:rules or asks to add, list, validate, show, remove, disable, enable, or explain project-specific upgrade rules — gem pins, gem swaps, private-source substitutions (Rails LTS, Sidekiq Pro), verification gates (Brakeman, Reek), policy overrides. Reads and writes .ruby-upgrade-toolkit/rules.yml at the project root.
Use when the user runs /ruby-upgrade-toolkit:status or asks for the current upgrade status, upgrade progress report, whether the upgrade is complete, or a summary of what's done and what's remaining. No arguments — detects everything from the project state. Produces a RED/YELLOW/GREEN health report.
Use when the user runs /ruby-upgrade-toolkit:upgrade or wants a fully automated Ruby/Rails upgrade pipeline. Orchestrates a phased upgrade by delegating per-phase execution to the fix skill and verification to the status skill. Keeps a live task list, pauses on RED verification, and lets the user continue, retry, or abort. Accepts ruby:X.Y.Z and optional rails:X.Y arguments.
