My research agent now runs six specialists in parallel. It used to do them one at a time.
Multi-agent orchestration just hit public beta. I upgraded the digest from #023. Six subagents, one lead, half the time.
I have been doing agentic engineering this whole time. Sort of.
Andrej Karpathy drew a line between vibe coding and agentic engineering. Here is why that distinction matters, where I land, and what it means for the software we build.
I built an agent that researches AI news for me while I sleep.
Claude Managed Agents, a Memory Store, and one email in my inbox every few days. Here is why I built it and what I want it to become.
I refused to believe Claude Code got worse. It had.
Plus Mythos Preview, Claude Design, Managed Agents memory, and the Vercel breach. A running log of three weeks I did not post.
Andrej Karpathy published LLM Wiki. Here is why I think RAG still makes sense for some things.
A pattern that went viral in April 2026. My instinct is that RAG and LLM Wiki solve different problems. I shared that thought on X and the conversation was interesting.
Contentful webhooks mean I never push to Supabase manually. Claude Code wrote it in 15 minutes.
The RAG search index now updates itself every time I publish a Field Note. One endpoint, one webhook, done.
I built RAG search on a headless CMS. The CMS did more work than the vector database.
Semantic search is live on fieldnotes-ai.com. Voyage AI, Supabase pgvector, Claude Sonnet. But the interesting part is what Contentful contributed.
I haven’t built AI search yet. But I already found what would have broken it.
While preparing to build RAG search for fieldnotes-ai.com, I audited 17 Field Notes and found 84 headings written as plain paragraphs. Claude Code fixed all via Contentful MCP.
I'm adding search to this site. It will understand what you mean, not just what you typed.
I'm building RAG-powered semantic search for fieldnotes-ai.com. Before writing any code, here's the two-pipeline architecture and every decision behind it.
Supabase emailed me at 9 PM. All my tables were publicly accessible.
I shipped a production app with Row Level Security disabled. Anyone with my project URL could read, edit, and delete everything. I didn't notice. Supabase did.
