Overview
xiaoyuze88/karpathy-llm-wiki is a zero-code, pure prompt-engineering boilerplate using a “Hot.md” focus cache. It is a Tier 4 starter template in the comprehensive report — the lightest possible setup.
Key Facts
- Approach: zero-code, pure prompt engineering
- Trick: “Hot.md” focus cache to keep context warm
- Role: opinionated minimal boilerplate
- Stack: Claude Code + prompts + Hot.md
Features
Core Architecture
- Zero-code — pure prompt engineering, no scripts or tools
- Hot.md focus cache — keeps frequently accessed context warm in LLM memory
- Prompt-only — everything driven by CLAUDE.md instructions
Ingest & Processing
- Agent-driven ingest — Claude Code processes sources via prompts
- Focus cache — Hot.md maintains context across sessions
Integration
- Claude Code native — designed for Claude Code prompt system
- No dependencies — zero packages, zero databases
Data & Storage
- Markdown files — standard wiki output
- Hot.md — focus cache for context management
Relationships
- llm-wiki — (type: belongs-to) prompt-only implementation
- claude-code — (type: operates-with) driven entirely by prompts/CLAUDE.md
- ronancodes-llm-wiki — (type: sibling-of) sibling boilerplate (RonanCodes is CLI-structured; this is prompt-only)
Implications
Shows that the pattern can run with no code at all — just prompts + a focus-cache file. Relevant to the user’s “too manual” concern only partially: it removes code, but the human still drives prompts.
