Claude Wiki — AI skill for Claude Code

Claude Wiki

**Persistent knowledge base for Claude Code projects.** Based on the [LLM Wiki](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f) methodology by Andrej Karpathy.

The Problem

Every time you start a new Claude Code session, your AI assistant starts from zero. No memory of what was discussed yesterday. No knowledge of decisions made last week. No awareness of lessons learned last month.

**Claude Wiki fixes this.** One command. 30 seconds. Your project has a brain.

What It Does

Claude Wiki bootstraps a structured wiki inside your project — interlinked Markdown files with YAML frontmatter, cross-references, and automatic mirroring to [Obsidian](https://obsidian.md/) via MCP.

Instead of rediscovering context from scratch each session, Claude builds and maintains a cumulative knowledge base:

• Ingests sources — articles, docs, notes dropped into raw/
• Extracts entities — technologies, libraries, APIs, services
• Maps concepts — patterns, architectures, methodologies
• Records decisions — context, options considered, trade-offs
• Preserves learnings — bug fixes, insights, root causes
• Answers queries — synthesized responses with citations to wiki pages

 You write       Claude          Co-evolved
 Claude reads    owns this       between you
 NEVER modifies  entirely        and Claude

**Three layers:**

1. raw/ — Immutable source material. You drop files here. Claude reads but never modifies
