◇ Could this help me?
Yes. The durable part of this is sound: plain markdown with front matter that states what a file is and what it links to, plus a scheduled pass that folds recent work in and prunes stale notes, is what keeps an agent-readable knowledge base useful rather than decorative. Treat the specific clipper and graph products as optional additions to research before installing, since the value sits in the structure and the maintenance routine and not in any one tool. This is a general practice.
Set up an agent-readable knowledge base in this repo. Create a top-level notes folder, define a front matter schema for every note stating what it is, what it links to, and what to read next, and write a maintenance routine that can run weekly to scan recent sessions and decisions, fold the durable parts into the notes, and flag stale entries for removal. Do not install any browser extension or third-party tool as part of this. If one would genuinely help, name it and summarize what it does and who maintains it so the decision can be made separately.
