m3taversal 00119feb9e leo: archive 19 tweet sources on AI agents, memory, and harnesses
- What: Source archives for tweets by Karpathy, Teknium, Emollick, Gauri Gupta,
  Alex Prompter, Jerry Liu, Sarah Wooders, and others on LLM knowledge bases,
  agent harnesses, self-improving systems, and memory architecture
- Why: Persisting raw source material for pipeline extraction. 4 sources already
  processed by Rio's batch (karpathy-gist, kevin-gu, mintlify, hyunjin-kim)
  were excluded as duplicates.
- Status: all unprocessed, ready for overnight extraction pipeline

Key Points

  • Filesystems + grep can replace naive RAG implementations
  • Database + virtual filesystem abstraction + grep is sufficient
  • Endorsement from LlamaIndex founder of the filesystem-over-RAG approach
  • References Mintlify/ChromaFS article as practical demonstration
