Agentic AI · Part 8
Trip Buddy: one agent, built up in 15 lessons
One trip-planning agent grown lesson by lesson, from a SQLite table to RAG, tools, an MCP server, long-term memory and a second agent over A2A. It covers every command, error and fix from my run: uv off the PATH, an OpenAI 429 that wasn't a rate limit, a Gemini 400 caused by dropped thought signatures, and an A2A timeout that looked like an outage. There's a reproduce-it-yourself guide at the end.
