Those are per-tool and static (only for claude). they are dumped into context every session whether relevant or not, and they are not structured. DecisionNode is tool-agnostic and retrieval is explicit: the AI searches when it needs context, not on every session. Also works across Claude Code, Cursor, Windsurf simultaneously from one store. i still use both claude.md AND decisionnode during development, each one serves a different purpose in my workflow, they complement each other pretty well
