Notes from the field.

Working notes on the craft — engineering at scale, the AI-era developer experience, frontend that most teams leave on the table, and whatever else has my attention this week.

Building anchor: dual-surface product pages, agents.json, delegated-authority checkout, and AEO instrumentation
Anchor is an open-source AI-native product catalog. Every product has a human page AND three statically-cached LLM-facing endpoints. A /.well-known/agents.json descriptor publishes capabilities in the Agentic Commerce Protocol shape. A delegated-authority checkout endpoint runs an eight-check pipeline. AEO instrumentation classifies 13 LLM crawlers and logs every fetch through a proxy so cache hits stay observed. Here are the design choices that mattered.

Loom: durable AI commerce with Vercel Workflows, exactly-once side effects, and a bounded agent gate
Loom is an open-source backend that demonstrates the patterns required to let an LLM influence real money movement safely. Four Vercel Workflows run end-to-end with durable sleep, exactly-once side effects, saga compensation, Stripe webhook drift reconciliation, and a deterministic authorization gate that bounds every agent decision. Ships with an adversarial eval harness and a failure-injection harness. Built on Vercel Workflows (GA), the Vercel AI SDK, Anthropic, Stripe, and Upstash.

Building Forge: a multi-agent debugging concierge in production-grade TypeScript
Forge is an open-source multi-agent debugging concierge. Point it at a stack trace and four specialist subagents fan out in parallel, each with a focused tool set, before a coordinator merges their structured findings into ranked hypotheses with calibration-weighted confidence. Built on the Vercel AI SDK plus Anthropic. This post walks the architecture: parallel agent orchestration, durable resumable sessions, cross-instance abort, Brier-score calibration as a feedback loop, and what production deployment would change.

Building Kev-O: a grounded RAG chatbot trained on my own writing
Kev-O answers questions about my work using only the public corpus I've written. Hybrid BM25 plus cross-encoder rerank, Claude streaming through the Vercel AI SDK, a daily USD cap so it can't blow up my API bill. Three surfaces, one brain. Here's what I built and what choices ended up mattering.
