Operate any Obsidian vault as a living, AI-first second brain: 45 slash commands across vault management, thinking tools, a research toolkit, and scheduled agents.
Plugin obsidian-second-brain from marketplace obsidian-second-brain in cirobarone78/Brain. Commands read from the repo's manifest — 1 month ago.
This plugin runs code on your machine — its hooks fire automatically on events like tool use and it starts local MCP servers. The exact commands are listed below; read them before installing.
obsidian-second-brainOperate any Obsidian vault as a living, self-rewriting second brain (an evolution of Karpathy's LLM Wiki pattern: sources rewrite existing pages, contradictions reconcile automatically, scheduled agents maintain the vault while you sleep). Use this skill whenever the user asks Claude to read, write,
/obsidian-second-brain:create-commandCreate a new obsidian-second-brain command via interview - zero markdown editing required
/obsidian-second-brain:idea-discoverySurface 3-5 next-direction candidates by reading ungraduated ideas, open project questions, and orphan research notes - what is worth working on next
/obsidian-second-brain:notebooklmVault-first source-grounded research via Gemini File Search. One command, no browser. The grounded parallel to /research-deep (which is open-web via Perplexity).
/obsidian-second-brain:obsidian-architectScan a codebase and write a maintained set of architecture notes into the vault - overview, per-module notes, key decisions. Re-run to refresh without clobbering your edits
/obsidian-second-brain:obsidian-board-hygieneBulk-triage a kanban board - surface stale items and archive, reschedule, or mark them done in one pass
/obsidian-second-brain:obsidian-boardShow or update a kanban board - flags overdue items, updates from conversation
/obsidian-second-brain:obsidian-brainstormMulti-turn Socratic brainstorm - one question per turn until the idea converges, then a design note with named alternatives and one recommendation
/obsidian-second-brain:obsidian-calendarOne calendar command with four modes - agenda (read a snapshot), reconcile (vault vs calendar gaps), meeting (event to note), schedule (task to event)
/obsidian-second-brain:obsidian-captureQuick idea capture - zero friction, saves to your ideas folder and mentions in daily note
/obsidian-second-brain:obsidian-catchupReview and process everything captured on the go from the Telegram journal bot - voice, text, images, PDFs, links - waiting in the catchup queue. You pull it when you are back at the laptop; nothing is processed autonomously.
/obsidian-second-brain:obsidian-challengeRed-team your current idea against your own vault history - finds contradictions, past failures, and flawed assumptions
/obsidian-second-brain:obsidian-connectBridge two unrelated domains using your vault's link graph - forces creative friction to spark new ideas
/obsidian-second-brain:obsidian-dailyCreate or update today's daily note - pulls calendar events, overdue tasks, and conversation context
/obsidian-second-brain:obsidian-decideRecord decisions - lightweight by default (logged to project notes), or a full ADR record with --formal
/obsidian-second-brain:obsidian-distillCondense a long note or source into key claims, each tagged with provenance back to the exact source block it came from
/obsidian-second-brain:obsidian-emergeSurface unnamed patterns from your recent notes - recurring themes, hidden connections, and conclusions you haven't explicitly stated
/obsidian-second-brain:obsidian-exportExport a clean structured snapshot of the vault that any agent or tool can consume - flat JSON, markdown index, or an OKF (Open Knowledge Format) bundle
/obsidian-second-brain:obsidian-findSmart vault search - returns results with context, not just filenames
/obsidian-second-brain:obsidian-graduatePromote an idea fragment into a full project spec with tasks, board entries, and structure
/obsidian-second-brain:obsidian-healthRun a vault health check - grouped by severity, detects contradictions, concept gaps, stale claims, and structural issues
/obsidian-second-brain:obsidian-ingestIngest a source into the vault - the vault rewrites itself around new knowledge. Every ingest updates entities, rewrites stale claims, synthesizes new concepts, and resolves contradictions.
/obsidian-second-brain:obsidian-initScan your vault and generate a _CLAUDE.md operating manual, index.md catalog, and log.md pointer
/obsidian-second-brain:obsidian-learnReview vault learnings, prune stale ones, surface active patterns - the vault's lessons compound or expire
/obsidian-second-brain:obsidian-logLog this work or dev session to the vault - infers project from context
/obsidian-second-brain:obsidian-panelConvene a panel of distinct perspectives on a decision - one independent verdict per lens, then a synthesis. A multi-persona complement to /obsidian-challenge
/obsidian-second-brain:obsidian-personCreate or update a person note from conversation context
/obsidian-second-brain:obsidian-projectCreate or update a project note - adds to board and daily note automatically
/obsidian-second-brain:obsidian-projectsLive project status from git + local docs - infers all context from vault notes, no config required
/obsidian-second-brain:obsidian-recapSummarize a time period from the vault - today, week, or month
/obsidian-second-brain:obsidian-reconcileFind and resolve contradictions in the vault - the vault maintains its own truth
/obsidian-second-brain:obsidian-recurringTrack a recurring obligation (payment, filing, ops) with a cadence and a computed next-due date
/obsidian-second-brain:obsidian-retrieval-evalMeasure how well vault search finds the right note for a natural-language question - recall@k and MRR, with the concrete failures
/obsidian-second-brain:obsidian-reviewGenerate a structured weekly or monthly review note from vault history
/obsidian-second-brain:obsidian-saveSave everything worth keeping from this conversation to the vault
/obsidian-second-brain:obsidian-synthesizeAutomatic synthesis - scans the vault for unnamed patterns and writes synthesis pages without being asked
/obsidian-second-brain:obsidian-taskAdd a task to the right kanban board with inferred priority and due date
/obsidian-second-brain:obsidian-visualizeGenerate a visual canvas map of your vault - see the shape of your second brain and how knowledge connects
/obsidian-second-brain:obsidian-worldLoad your identity, values, priorities, and current state in one shot - with progressive context levels to avoid burning tokens
/obsidian-second-brain:podcastExtract metadata, transcript, and summary from a podcast episode, saved as an AI-first note in the vault
/obsidian-second-brain:research-deepVault-first deep research - scans the vault, fills gaps (Perplexity + Grok when keyed, free key-less sources otherwise), synthesizes a delta, then propagates updates across people/projects/ideas via /obsidian-save
/obsidian-second-brain:researchWeb research with citations - Perplexity Sonar when an API key is set, free key-less sources (Wikipedia, HackerNews, arXiv, Reddit, and more) otherwise. Deep dossier with summary, facts, timeline, players, contrarian views, open questions
/obsidian-second-brain:vault-deep-synthesisDeep cross-reference of everything the vault knows about one topic - agreements, contradictions, stale claims, and coverage gaps. Pure vault, no network
/obsidian-second-brain:x-pulseScan X for what's trending in a topic - themes, voices, hooks, and post ideas powered by Grok + Live Search
/obsidian-second-brain:x-readDeep-read an X (Twitter) post via Grok + Live Search - verbatim post, thread, TL;DR, claims, reply sentiment, voices to watch
/obsidian-second-brain:youtubeExtract transcript, metadata, and top comments from a YouTube video - summarized via Gemini (free tier) or Grok and saved to vault. Add --visual to also read the video's frames (scene detection)
