Why Your AI Coding Agent Forgets Everything (and 3 Ways to Fix It)

Every AI coding agent starts each session with an empty short-term memory, so it repeats mistakes you already corrected. This video explains why, and three ways to fix it: a CLAUDE.md file done properly, Claude Code's auto memory, and Hindsight, an open-source memory system that learns from past sessions. Plus an everyday example, with and without memory, for anyone who is not a developer.
