Cross-CLI skill turning a vault into an AI-first knowledge base with hybrid semantic search and self-maintaining notes (~3.5k stars).Our read
Why it ranks #3
The existing source records roughly 3.5k GitHub stars, showing credible niche interest in an AI-first Obsidian workflow but substantially less adoption than the leading vault and RAG projects.Here is the catch
Smaller community means fewer independent reliability signals
Embedding and index setup add local complexity
Automated note maintenance can make surprising changes without strict review
Does this well
Hybrid search addresses limitations of filename or keyword lookup alone
Cross-agent design avoids locking the workflow to one CLI
Markdown vault remains portable and user-controlled
