Your Perfectly Organized System Is Making Things Harder to Find

When content changes constantly, your perfectly organized indexes become traps. Claude Code abandoned RAG for three ‘dumb’ tools β€” glob, grep, read β€” and it worked better. The lesson: exploration cost isn’t always bad. It depends on whether what you’re exploring is stable. In fast-moving environments, a living search beats a dead map every time.

Your AI Knowledge Base Is Just an Expensive Digital Junkyard

You have 200 articles in your AI knowledge base and can’t recall any of them when it matters. I built that same prison. The dirty secret: processing is not understanding, and LLM-summarized insights are not yours. I spent six months rebuilding an Obsidian system around a brutal truth β€” the only knowledge worth keeping is born from friction between machine processing and human judgment. Before you build that RAG pipeline, ask if your ‘knowledge’ is actually yours.

The Obsidian Plugin That Will Change How You Think About AI (And Why Karpathy Would Hate It)

The real value isn’t his knowledgeβ€”it’s the friction that builds your own mental models. A local knowledge graph turns passive fear into active mastery.
