optimalone/build-your-own-coding-agent: Source code for the Build Your Own Coding Agent book

Engineering considerations The repository optimalone/build-your-own-coding-agent provides the reference implementation for the Build Your Own Coding Agent book, a tutorial that guides developers through constructing a terminal‑based autonomous AI coding agent in pure Python. It targets engineers and learners who want to understand the mechanics of agent loops, tool use, and context management without relying on high‑level orchestration libraries such as LangChain or vector databases. Readiness is evident from the documented requirements: Python 3.10+ and an Anthropic API key for cloud models, with optional DeepSeek keys and Ollama for local models. The README includes a quick‑start script that clones the repo, creates a virtual environment, installs dependencies, and provisions the API key, indicating that the
