Rebuild the knowledge base vector index
Ingest raw documents into the knowledge base pipeline
Initialize a new knowledge wiki in the current directory
Run health checks on the knowledge base wiki
Autonomously compiles all pending inbox items into atomic wiki notes with dedup, wikilinks, and index refresh
Analyzes wiki knowledge gaps and autonomously researches and creates notes to fill them
Reviews recently compiled notes for accuracy, consistency, proper tagging, and connection quality
Reduces orphan rate by scanning notes and adding wikilinks to connect related content

A collection of Claude Code plugins for personal knowledge management.
| Plugin | Description | Install |
|---|---|---|
| karpathy-llm-wiki | Karpathy-style knowledge wiki — ingest, compile, search, and maintain a semantic knowledge base | claude plugin add cajias/second-brain-plugins --plugin karpathy-llm-wiki |
These plugins implement different strategies for building and maintaining a personal knowledge base using Claude Code as the engine. Each plugin is a self-contained system with its own workflow, data model, and commands.
The goal: turn your scattered notes, articles, papers, and conversations into a structured, searchable, interconnected knowledge graph — with AI doing the heavy lifting.
# Install a plugin
claude plugin add cajias/second-brain-plugins --plugin karpathy-llm-wiki
# Initialize a wiki in any directory
cd ~/my-wiki
/kb-init
# Start building knowledge
/kb-ingest file paper.pdf

npx claudepluginhub cajias/second-brain-plugins --plugin karpathy-llm-wikiTrue Zettelkasten for Claude Code - atomic notes, semantic search, and automatic hubs
Enforces proper AWS authentication via isengardcli. Prevents direct aws/cdk/deploy commands without credentials. Uses environment variables (DEV, GAMMA, PROD) for account selection with color-coded warnings for non-dev environments.
Development workflow tools - README generation, code review, and more
Continuous learning system that extracts reusable skills from Claude Code sessions. Uses multi-hook architecture with breakthrough scoring, TF-IDF duplicate detection, user/project skill taxonomy, and unified knowledge detection (corrections + teaching patterns).
Automated PR monitoring with Stop hook that auto-resumes Claude Code when new commits are detected
Upstash Context7 MCP server for up-to-date documentation lookup. Pull version-specific documentation and code examples directly from source repositories into your LLM context.
Comprehensive C4 architecture documentation workflow with bottom-up code analysis, component synthesis, container mapping, and context diagram generation
AI-powered wiki generator for code repositories. Generates comprehensive, Mermaid-rich documentation with dark-mode VitePress sites, onboarding guides, deep research, and source citations. Inspired by OpenDeepWiki and deepwiki-open.
Documentation generation, code explanation, and technical writing with automated doc generation and tutorial creation
Claude + Obsidian knowledge companion. Sets up a persistent, compounding wiki vault (Karpathy's LLM Wiki pattern). v1.7 "Compound Vault" + v1.8 methodology modes close 5 of 5 priority gaps from the May 2026 compass artifact. Ships: substrate alignment with kepano/obsidian-skills, default Obsidian CLI transport, hybrid retrieval (contextual prefix + BM25 + cosine rerank per Anthropic's Sept 2024 research), per-file advisory locking for multi-writer safety, pre-commit verifier agent, AND methodology modes (LYT / PARA / Zettelkasten / Generic) for first-class organizational support no other Claude+Obsidian competitor offers. v1.7.x audit closure: every BLOCKER + HIGH + MEDIUM + LOW finding from the v1.7.0 audit is CLOSED or DEFERRED-with-rationale. Optional DragonScale Memory extension (log folds, deterministic addresses, semantic tiling lint, boundary-first autoresearch).
Complete AI coding workflow system. Self-correcting memory + persistent FTS5-indexed research wikis + auto-research loop + multi-LLM council on a single SQLite store. 33 skills, 8 agents, 22 commands, 37 hook scripts across 24 events. Cross-agent via SkillKit.
