Summary¶
AI engineer and YouTuber who adapted Karpathy's LLM Wiki pattern from external data ingestion to internal data — building a self-evolving memory system for Claude Code that captures conversation logs and extracts structured knowledge.

Extended the LLM Wiki pattern to codebase memory:
- Claude Code Hooks — uses session start, pre-compact, and session end hooks to automatically capture conversation summaries
- Daily logs — equivalent to the
raw/folder; stores summarized takeaways from every Claude Code session - Daily flush process — extracts concepts and connections from logs, populates the wiki
- Claude Agent SDK — runs behind the scenes to summarize conversations without requiring API key setup
- Hot cache (
hot.md) — ~500-character cache of most recent context for quick access - Fully customizable prompts for compilation and flushing; the system can improve itself
Notable insight: the system gives Claude Code a memory that evolves with the codebase, remembering decisions made and how the project evolved over time.
