Obsidian Source Ingestion & Wiki Synthesis
Integrate sources into an Obsidian wiki with traceable claims, duplicate checks, explicit contradictions, and updated synthesis.
Before & after
Same prompt, same agent — the only difference is the skill.
Building a personal knowledge base is a great idea. Many people use tools like Obsidian to organize notes and then manually link ideas together. You could set up a folder structure, create pages for key concepts, and gradually build out connections between them. The challenge is keeping it updated and making sure the relationships stay meaningful over time. You might also look into existing second-brain templates to get started. It's really more about your personal workflow—what matters is finding a system that works for you and sticking with it.
SECOND BRAIN SETUP VAULT STRUCTURE → Create an Obsidian vault with three folders: entities (people, companies, concepts), sources (papers, articles, interviews), and synthesis (your compiled insights and cross-references) INCREMENTAL INGESTION → Send Claude a link or text block; it extracts key claims, entities mentioned, and connections to existing pages → Claude auto-proposes new entity pages or updates to existing ones → You review before pages commit to the vault KNOWLEDGE GRAPH GROWTH → Each source ingestion adds backlinks: "data consistency (see also: database integrity, CAP theorem)" → Synthesis pages pull from multiple sources: "Why databases choose consistency over availability—three case studies" → Obsidian graph view shows your emerging clusters of related concepts QUERY FROM MEMORY → Instead of re-reading sources, ask Claude questions grounded in your vault → Claude cites which entity or synthesis pages answer your question → Example: "Which databases handle write conflicts best?" → Claude returns your schema comparison page + linked sources
About this skill
Your second brain keeps collecting article summaries, but its concept pages still say what they said months ago. This skill integrates new evidence into your Obsidian wiki, preserving where claims came from and showing when a new source actually changes your understanding.
What it does
- Matches names, aliases, and source identifiers before creating pages.
- Extracts claims with conditions and citations instead of copying whole summaries into every note.
- Updates existing entity and concept pages while preserving your commentary.
- Separates genuine contradictions from differences in definitions, populations, or measurement.
- Maintains useful cross-references and revises the topic synthesis in place.
- Checks changed links and reports applied edits separately from proposed patches.
What you get
Updated source, concept, entity, and synthesis notes, plus a concise change report listing conflicts and verification results. Without vault access, you receive concrete Markdown patches with assumptions clearly marked.
Best for
Researchers, students, writers, and builders who already use Obsidian and want accumulated reading to improve a connected body of knowledge across sessions.

description: Integrate sources into an Obsidian knowledge base by matching existing pages, attaching evidence to claims, recording contradictions, maintaining cross-references, and revising topic synthesis. Use when the user says "add this paper to my wiki", "ingest this article", "update my second brain", "my notes keep duplicating concepts", "these sources disagree", "refresh my research synthesis", or "connect this reading to my existing notes".
