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

gemini's free tier is pretty generous, and no credit card required to use the free api. however OpenAI embeddings support is on the roadmap if u checked the repo!
