Obs
Manage Obsidian vaults from the terminal using obs CLI. Search notes, manage tags, properties, links, tasks, daily notes, templates, bookmarks, plugins, canvas, and bases. Use when the user works with Obsidian vaults, markdown notes, or wants to query/modify vault content from the command line.
Ingest
Ingest source material (URLs, PDFs, images, repos, papers, YouTube transcripts) into the vault's `raw/` directory as clean markdown. Use when the user says 'add this to my knowledge base', 'ingest this article', 'clip this page', 'import this paper', or drops a link/file to be filed. Part of the knowledge-base pack implementing Karpathy's raw→compiled-wiki workflow.
Act
Turn thinking into doing with Obsidian vaults. Get focused next actions, make decisions using your own notes, or promote buried ideas into standalone notes. Use when the user has ideas but needs help prioritizing, deciding, or organizing for action.
Obsidian Brain Vault
Brain Vault — the free, community-built Karpathy LLM-Wiki for Obsidian. CLI + MCP-ready. Claude Code skill pack included. obs + obs-mcp.
Review
Daily and weekly review rituals for Obsidian vaults. Morning planning, evening wrap-up, and weekly reflection using your vault data. Use when the user wants structured review habits or asks about their day/week.
Lint
Health-check a markdown knowledge base. Find broken links, orphan notes, missing frontmatter, inconsistent facts, duplicate concepts, and suggest new articles to fill gaps. Use when the user says 'lint my wiki', 'check my KB health', 'find inconsistencies', 'what should I write next'. Part of the knowledge-base pack.
Render
Render knowledge-base content into shareable artifacts: Marp slide decks, matplotlib charts, printable briefs, Mermaid diagrams, and concept-graph visualizations. Output files land in the vault's outputs/ folder and re-open in Obsidian. Use when the user says 'turn this into slides', 'chart this data', 'build a deck from my notes', 'visualize the concept graph'. Part of the knowledge-base pack.
Connect
Discover hidden relationships between ideas in Obsidian vaults. Find how two topics bridge, trace an idea's evolution, or surface recurring themes. Use when the user senses connections but can't articulate them, or wants to find patterns in their notes.
Clarify
Articulate and clarify rough thoughts in Obsidian notes. Rewrite messy notes clearly, expand short ideas into full thoughts, or simplify tangled notes to core points. Use when the user has notes that need refining or when they know what they mean but can't say it.
Compile
Incrementally compile the vault's raw/ directory into a structured wiki of concept pages, summaries, and backlinks. Use when the user says 'compile my knowledge base', 'update my wiki', 'fold in new research', or finishes a batch of ingests. Part of the knowledge-base pack implementing Karpathy's raw→wiki workflow.
Reflect
See your own thinking patterns in Obsidian vaults. Find emerging project clusters, challenge your assumptions, or track how your views have changed. Use when the user wants meta-awareness of their notes and thinking.
Qa
Ask complex questions against a compiled markdown wiki. The LLM searches relevant notes, synthesizes an answer, and files the result back into outputs/ as a linked markdown report. Use when the user asks 'what does my vault say about X', 'research Y using my notes', 'summarize everything I know about Z'. Part of the knowledge-base pack implementing Karpathy's raw→wiki→Q&A workflow.
Capture
Brain dump and quick capture tools for Obsidian vaults. Stream-of-consciousness dumps, one-liner captures, and rapid-fire note creation. Use when the user wants to quickly get thoughts out of their head and into their vault.
