Three sessions in, it asks which package manager you use. Again.
You are deep in a refactor and your agent has forgotten, again, where the migrations live, why the auth middleware is shaped the way it is, and which package manager you use. So you paste the same three paragraphs into the prompt one more time. With Contexel those facts live as small Markdown notes. Your agent calls get_context with the task and gets back only the ones that fit, inside its size limit, with the source stamped on each. When it learns something new mid-session it saves a note with observe, and you approve anything lasting. The third session starts as sharp as the first one ended.
