# Knowledge base This folder is the builder agent's long-term memory of **this company and product** — short markdown notes, not code. The agent reads these at the start of every session and updates them as it learns durable facts: domain concepts, decisions and the reasons behind them, preferences, and anything that makes the agent more personalised over time. Suggested notes (create as needed): - `product.md` — what the product is, who it's for, the core problem it solves - `glossary.md` — the company's own terms and what they mean - `decisions.md` — choices made together and why - `preferences.md` — style, scope, and things to avoid Keep notes concise and current. Do not store secrets or credentials here.
