Prompt

Convert this diagram into a hand-drawn, whiteboard-style illustration:

Style requirements:
- Sketchy, slightly wobbly lines — nothing perfectly straight
- Warm cream or off-white background, like paper
- Three color-coded columns: amber/orange for Planning, green for Building, purple/violet for Runtime
- Rounded boxes with visible hand-drawn strokes
- Clear downward arrows within each column, dashed arrows connecting columns left-to-right
- Casual handwritten font, large enough to read clearly
- Decorative small stars or doodles in the margins
- The overall feel should look like a talented person sketched this on a whiteboard

Diagram content:

Title: "How we used Claude"

PLANNING column (amber/orange):
  Box 1: "CLAUDE.md brief" — Hackathon rubric fed into Claude's context
  Box 2: "Plan iteration" — LLM-PLAN1 → PLAN4, Claude pushes back and refines
  Box 3: "Claude picks best plan" — All team ideas compared, Claude selects and explains
  Box 4: "Per-person Plan Mode" — Each member picks a role, Claude writes their spec

BUILDING column (green):
  Box 1: "5 parallel Claude agents" — One per layer (chips: Rust engine, Eval generator, Backend, Frontend, Tester)
  Box 2: "Claude writes all the code" — Every file written and reviewed with Claude
  Box 3: "Interface contract" — Rust↔Python spec designed with Claude, committed before build started

RUNTIME column (purple):
  Box 1: "① Interpret" — Maps your words into chess concepts
  Box 2: "② Generate" — Writes evaluate(board) live, from scratch
  Box 3: "5-gate validation" — syntax · safety · sanity · determinism · variance
  Box 4: "③ Narrate" — After every move, Claude narrates in the personality's voice
