Literature reviews, market scans, due diligence, fact checks and personal knowledge bases.
You have a folder of interlinked markdown pages with an index and a change log, built from your sources, that you can read in Obsidian and query through the agent, with every change reviewable in git.
You get a screening log, an evidence table with one row per included paper, a synthesis that cites only papers you hold, and a reference list where every entry resolves to a real record.
You get a report where every factual claim links to a source that loads and says what the report claims, plus a table of the claims you cut or changed.
Each weekday you get one message with the few new papers and releases that match your interests, each with a link, a one-line reason it matters, and a clear note when nothing new appeared.
