AI summary
Auto-generated overview of what this skill does and when to reach for it.
Turns Obsidian into a self-updating AI wiki that reads sources, organizes notes, and answers questions with citations from your growing knowledge base.
Use this when
- You dump research papers, docs, or meeting notes and want them auto-organized into a searchable wiki
- You ask questions and want answers grounded in your own notes, not generic training data
- You need a persistent memory between sessions so you don’t re-explain context every time
- You want automatic cleanup of broken links, orphaned pages, and stale claims in your notes
- You’re researching a topic and want autonomous multi-round web searches that fill knowledge gaps
Don't use when
- You only need a simple chat interface over existing notes
- You prefer manual note-taking without automation
- You work in a team that doesn’t use Obsidian
Capabilities
- Auto-creates entities, concepts, and cross-references from imported sources
- Maintains a hot cache for session memory between conversations
- Runs 8-category linting (orphans, dead links, contradictions, gaps)
- Supports LYT/PARA/Zettelkasten/Generic methodology modes
- Performs 3-round autonomous research with gap-filling
- Uses hybrid retrieval (prefix + BM25 + cosine rerank) for precise answers
