Frequently Asked Questions About Graham Mackie
FAQPage SchemaWhat tasks can I accomplish with gmackie's skill collection?▼
You can build and release Expo/React Native apps (EAS Build, Submit, TestFlight, OTA updates), develop on Cloudflare (Workers, D1, Durable Objects, Pages), apply Supabase Postgres best practices, run Playwright browser tests, and execute structured engineering playbooks for debugging, code review, triage, and architecture design.
Who is the target audience for these skills?▼
Full-stack and mobile engineers using AI coding agents in Cursor, Claude Code, or Codex. The collection suits developers shipping Expo mobile apps, Next.js SaaS products on Cloudflare, and teams wanting disciplined review, verification, and planning loops inside agent-driven sessions.
How do I install and run these skills?▼
Skills are Markdown frontmatter files sourced from public GitHub repos (expo/skills, cloudflare/skills, cursor/plugins, mattpocock/skills). Copy the skill folder into your agent's skills directory; invocation is either user-triggered via slash commands like /figure-it-out or model-triggered automatically by matching task descriptions.
Are these skills open source and what do they cost?▼
Nearly all skills carry the MIT license and are free to use. However, several Expo skills depend on EAS, a paid hosted service (EAS Build, Submit, Hosting, Observe, Simulator), so the skill content is free while the underlying cloud services may require a paid Expo plan.
What prerequisites do these skills require?▼
Prerequisites vary: Unity skills need Unity Editor and unity-mcp; ESP32 skills need ESP-IDF; SaaS bootstrapping needs Node.js 18+, pnpm, and Turbo; Stripe integration needs a Stripe account; React UI skills need Tailwind and shadcn/ui; Cloudflare skills assume Wrangler configuration in the repo.
