llm-wiki-skill — Multi-Platform Knowledge Base Builder

Skill by ara.so — Daily 2026 Skills collection.

Build a persistent, interlinked personal knowledge base from URLs, PDFs, markdown files, and raw text. Based on Karpathy's llm-wiki methodology: knowledge is compiled once and maintained, not re-derived from raw docs on every query.

What It Does

• Ingests articles, tweets, PDFs, YouTube transcripts, WeChat posts, and plain text
• Routes each source type to the best extraction tool automatically
• Generates structured wiki pages with [[bidirectional links]]
• Produces entity pages, topic pages, source summaries, and comparisons
• Outputs Obsidian-compatible local markdown files
• Detects orphaned pages, broken links, and contradictions via health checks
