A practical reference to the patterns, surfaces, and design principles behind AI agents — from primitives to production.
Agent Experience is an open-source reference site covering 26 patterns across five categories:
- Foundations — Mental models like tool use, ReAct, planning, and reflection
- Patterns — Concrete architectures like MCP, computer use, multi-agent orchestration, and skills
- Infrastructure — The plumbing: memory, context management, sandboxes, guardrails, and harnesses
- Surfaces — Where agents meet humans: generative UI, IDE agents, CLI agents, and chat interfaces
- Design — Making agents usable: human-in-the-loop, observability, and evaluation
Each pattern includes a description, key ideas, real-world examples, and links to go deeper.

Contributions are welcome! A few ground rules:
- This is not an advertising platform. PRs that exist primarily to promote a company or product will not be merged. We want to showcase the best, most useful examples — not the ones with the biggest marketing budget.
- PRs are not guaranteed to be merged. We review everything and prioritize quality and relevance. Don't take it personally if we pass.
- Focus on what's genuinely best-in-class. If you're adding an example, it should be something practitioners actually use and recommend. Include a URL and a concise, honest description.
- Keep descriptions factual. No superlatives, no marketing copy. Say what it does, not how great it is.
- Adding a new example that's widely adopted and genuinely useful
- Fixing outdated information (dead links, incorrect descriptions)
- Adding a missing pattern that belongs in the reference
- Improving the site's accessibility or performance
- Adding your company's product as an example when it's not widely known or adopted
- Marketing-style descriptions ("the world's leading...", "the most powerful...")
- Removing competitors' examples to make room for yours
