Scaffold the Mimas agent instruction file tree for any repository — AGENTS.md at root, subdomain CONTEXT.md files, and the full agents-docs/ hierarchy (a sibling of any existing docs/, kept separate so human-maintained project docs stay untouched). Every file is tailored to the repo's actual tech stack, git platform, and conventions. Use this skill whenever someone wants to set up agent instructions, onboard a repo for AI-assisted development, add AGENTS.md / CONTEXT.md files, create engineering docs for agents, or mentions "set up agentic repository" or "mimas template". Even if they just say "set up this repo for agents" or "add agent docs", this is the skill to use.
First-run setup wizard for Remotion Superpowers. Checks dependencies, scaffolds a Remotion project if needed, installs and updates Remotion's 12 official Agent Skills (a required companion), walks through API key configuration, and verifies MCP server connections.
Set up a repository for the other skills using your chosen tracker, asking where tickets live when that choice is missing. Supports GitHub Issues, Linear, Jira, markdown files under .scratch/, or a tracker you describe in a paragraph. Detects and writes the configuration and a pointer block in CLAUDE.md or AGENTS.md. Run once per repo, and again to refresh configuration or switch trackers. Use when asked to set up mana, set up this repo for the skills, choose the issue tracker, connect Linear or Jira, point the skills at a tracker, or /setup-mana.
Complete workflow for migrating an existing frontend application to SGDS web components. Use this skill when a user wants to migrate from another UI library (MUI, Chakra UI, shadcn/ui, Ant Design, Vuetify, Angular Material, Bootstrap, etc.) to SGDS, or asks how to start using SGDS in an existing project. Covers four phases: (1) scan the current frontend tech stack, (2) install and configure SGDS with font, foundation CSS, and utilities, (3) migrate tests (Path A: Vitest + Playwright, or Path B: patch existing Jest/RTL), (4) replace old styling systems with SGDS v3 utilities, plus a post-migration verification checklist. React fully supported.
Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI, including chat interfaces. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", "switch to --preset", and for building a design system or applying a DESIGN.md or brand spec to shadcn/ui.

Rewrites over-engineered Ruby and Rails classes (stateless service objects, behaviorless value objects, class-method-only classes, deep inheritance, needless metaprogramming) as Data, Struct, Hash, modules, or pure functions, after finding every caller and getting a green test baseline, or reports findings when asked to review. Use when the user says "simplify this Ruby", or when asked to refactor, simplify, review, or cut boilerplate from a Ruby or Rails class, value object, service object, gem, or branch diff (hand-written initialize, readers, ==, eql?, or hash; call-only classes; Struct vs Data), or when tests need heavy mocking. Not for a broad Rails tech-debt audit; use auditing-rails-tech-debt.
