ThoughtDAG argues the wires between nodes should be the context window.

chenxiachan/thoughtdag reached 136 points and 61 comments on Show HN with one rule: on an infinite canvas of question/answer nodes, only wired upstream nodes get sent to the model. Shows token counts per request before you send, lets you branch, merge, prune, and rebuild the graph, and imports existing ChatGPT and Claude exports so old threads become editable graphs. Local-first, Ollama or any OpenAI-compatible endpoint, and it deliberately refuses agent autonomy: "human in the loop, model on the wires, no autonomous agent redrawing your graph." A direct counter-position to the auto-compaction every major coding agent now does invisibly.
