Turns your Obsidian vault into a queryable knowledge base without leaving Claude. It walks up from your current directory to find config, reads hot.md for recent changes, then uses a tiered search strategy: index scan first, optional QMD semantic search if configured, then progressively deeper page reads only when needed. You can ask relationship queries and it'll check the relationships blocks in frontmatter, not just grep for keywords. There's a fast mode triggered by "quick answer" that stops at summaries without opening page bodies, and a visibility filter if you want to exclude internal or PII tagged pages from results. The protocol is explicitly cost aware, with a primitives table that stops you from doing expensive full reads when frontmatter would answer it. Works across projects as long as you've got the vault path in config.
