This is a working catalog of agentic systems — the patterns behind them and the demos that prove them out. There are two ways to use it.

Learn by concept

The concept index is a learning path, from fundamentals to production concerns:

1. Foundations — what an agent actually is, and how it uses tools.
2. Reasoning & orchestration — workflows, routing, and multiple agents working together.
3. Tools & protocols — MCP, A2A, and agent registries.
4. Memory & knowledge — memory and retrieval (RAG).
5. Interfaces — browser/computer use, voice, accessibility, multimodal.
6. Quality — evaluation and reusable skills.

Each concept links to the demos that demonstrate it.

See the work

The gallery lists every demo, filterable by concept and by access level:

• Public — code is on GitHub; jump straight in.
• Private — no public code, but a case study shows what it does and how it’s built.
• Local — lives on a laptop for now; a write-up or video stands in until it’s promoted.
