Markdown is not agent memory. It's a sticky note.

Everyone's doing it. A MEMORY.md in the project root. A context.md the agent reads at session start. A few bullet points about past decisions. Maybe a CLAUDE.md if you watched Karpathy's video. for one person running local agents? It works Karpathy's setup is clever and clean. But the moment you try to do anything serious with agents, markdown falls apart. Here's how: The file has no concept of confidence: "We use Postgres" and "I think the retry logic might be buggy" look identical. Both are just sentences. Your agent treats them the same way.
