Tip: nanobot's ~4K-Line Agent Loop Is a Readable Reference for Minimal Agent Architecture

GitHub·medium signal

If you're building a personal agent or studying agent internals, nanobot's codebase is one of the most readable: complete agent loop with memory, MCP, multi-platform chat, and multi-provider LLM access in roughly 4,000 lines of Python. Compare to larger frameworks to identify which abstractions you actually need versus which are framework bloat. MIT licensed.
