An open-source project I built: 12 hands-on challenges that turn Anthropic's courses into a real, working multi-agent product. No toy examples — production patterns from challenge one. It is part of how I keep the craft I bring to clients sharp.
View on GitHub →Every lesson from Anthropic's courses becomes a real, working feature. You don't read about a pattern — you ship it.
A Claude client with automatic model fallback, business logic replaced by Claude-powered decisions, token streaming over SSE with image analysis.
A versioned prompt lab with A/B tests, 17 tools wired across 5 agents, an agentic support chatbot, production domain prompts.
A code-graded evaluation engine, Claude-judges-Claude model evals, and a promptfoo CI pipeline for continuous evaluation.
A self-improving prompt optimizer that learns from evaluation history, and a full-stack dashboard tracking progress.
Clone it, run it, learn from it. It works without an API key — graceful fallbacks everywhere.
