106 cross-runtime skills and 7 specialist agents for Claude Code, Codex, and multi-agent workflows — validated, cataloged, and organized into job-shaped workflows.
npx skills add majiayu000/spellbook --skill frontend-design --skill app-ui-design --skill ui-design-system --skill figma-to-reactOne source tree installs into both Claude Code and Codex. Write a skill once, use it from any coding agent.
Every installable skill is checked by the registry validator before it ships — structure, frontmatter, dependencies.
Larger skills ship references, templates, scripts, and evals — not one giant prompt that eats your context.
Engineering, operations, product, UI, content, and agent workflows — one catalog, battle-tested in production.
Every skill is a directory with hard rules, practical examples, and verification checklists. Pick a school, or install them all.
