The first open-source harness builder for AI coding. Make AI coding deterministic and repeatable.

A workflow engine that lets you define AI-powered software development processes (planning, coding, testing, review) as YAML files and run them reliably with Claude Code.

Context engineering is the new vibe coding - it's the way to actually make AI coding assistants work. Claude Code is the best for this so that's what this repo is centered around, but you can apply this strategy with any AI coding assistant!

A starter template that helps AI coding assistants produce better results by giving them structured context about your project before they write any code.

All the open source AI Agents hosted on the oTTomator Live Agent Studio platform!

Skill to give Claude Code (and any coding agent) the ability to generate beautiful and practical Excalidraw diagrams.

Run all your local AI together in one package - Ollama, Supabase, n8n, Open WebUI, and more!

Follow along with my AI Agents Masterclass videos! All of the code I create and use in this series on YouTube will be here for you to use and even build on top of!

Web Crawling and RAG Capabilities for AI Agents and AI Coding Assistants

Give Claude Code a memory that evolves with your codebase. Hooks automatically capture sessions, the Claude Agent SDK extracts key decisions and lessons, and an LLM compiler organizes everything into structured, cross-referenced knowledge articles - inspired by Karpathy's LLM Knowledge Base architecture.
