## Nauti's Take

Karpathy tweets, the world ships — we know the pattern. But CacheZero is more than a weekend vibe-coding project: repurposing Claude Code as a 'knowledge compiler' rather than a code assistant shows how agent tooling is hitting unexpected use cases. The fragility around SCHEMA.md is honestly communicated, which is refreshing. Anyone already in the Obsidian ecosystem should try it; for everyone else, it sits at the productive edge of the PKM hype cycle — worth watching, not yet worth betting on.
