The request is generic ('implicit-decision-capture', what to use) and names no product, platform, or constraint. Several candidates offer ways to capture decisions: 3ngram explicitly saves decisions over MCP 9, Adrian Czuczka's mason exposes a save_decision action 7, GitHub provides an ADR creation action 2, and Notion provides notion-knowledge-capture for turning conversations into structured pages 3. Which fits depends on where decisions are made and where they should be stored.
A question back: Where do your decisions currently happen (chat with an AI assistant, pull requests, meetings, code), and where should they be captured (a wiki, a repository, or a memory layer for your AI tools)?
