Frequently Asked Questions

FAQPage Schema

How to install phase?▼

Run `npx skills add phase-rs/phase --all -g -y` in your terminal to install all skills in this collection globally.

What does the phase skill collection do?▼

It provides step-by-step workflows for adding cards, keywords, triggers, and effects to a Magic: The Gathering rules engine, plus testing, review, and release procedures.

Can I contribute a card without knowing Rust?▼

Yes. Hand the provided prompt to your coding assistant and it follows the engine-implementer skill end to end, opening a pull request when done.

How do the skills prevent wrong game rules?▼

Every rules citation must be verified against the official Comprehensive Rules document, and each change requires runtime tests that fail if the fix is reverted.

Do these skills work with Claude Code and Codex?▼

Yes. All skills follow the standard SKILL.md format and run in Claude Code, Codex, Cursor, and other compatible coding assistants.
