Brad Frost's Atomic Design methodology for UI component hierarchies: atoms (indivisible elements), molecules (small groups of atoms), organisms (complex sections of molecules), and templates (page layouts). Enforces bottom-up composition (never skip levels), presentational components (data via props, events via callbacks, no data fetching), design tokens for all visual properties, and composition over inheritance. Use when building user interfaces, creating component libraries, organizing frontend code, designing form systems, or structuring any UI. Triggers on: "build a component", "component hierarchy", "design tokens", "presentational components", "composition over inheritance", "React/Vue/SwiftUI components", "atomic design". Applies to any UI framework.

Run Karpathy-style autonomous ML search on a real training repository. Use when the user needs to set up or operate `karpathy/autoresearch`, choose the right run mode (setup, `program.md`, bounded loop, result interpretation, or constrained-hardware adaptation), and preserve the immutable `prepare.py` / 300-second / `val_bpb` contract. Not for prompt evaluation, LLM app observability, or repo-local `SKILL.md` optimization — route those to LangSmith, Promptfoo, Braintrust, or `skill-autoresearch`. Triggers on: autoresearch, autonomous ML experiments, `program.md`, `train.py`, `val_bpb`, overnight GPU loop, fixed eval harness.
