Elisa is a block-based visual IDE where kids design software by snapping blocks together and AI agents build it. Users compose specs using seven primitives; Goals, Requirements, Minions (Agents), Skills, Rules (Hooks), Portals (MCP/CLI/hardware connectors), and Deployments, then hit Go. A meta-planner decomposes the spec into a task DAG, and Builder, Tester, and Reviewer agents execute it with live visibility into planning, coding, testing, and deployment. A teaching engine surfaces age-appropriate programming concepts as agents work.

Built solo in one week, entirely with Claude Code. I architected and spec'd; Claude wrote every line. 39,000 lines of TypeScript/Python/React. 1,500 tests. 76 commits. The primary artifacts of software creation are shifting from source code to specs and tests. Elisa makes that future accessible to the next generation.
