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.

mdx-corpus: a tiny package that turns an MDX directory into a retrieval-ready corpus
While building Kev-O I kept rewriting the same parse-and-chunk step for MDX content. So I pulled it out into a small npm package that does file-in / JSON-out and gets out of the way. No embeddings, no vector store, no LLM. Three responsibilities, sharp boundaries.

streamfield: a small library for AI streams that don't look broken
When the Vercel AI SDK streams a structured response, the fields flicker and snap into place as they arrive. streamfield is a tiny React library that fixes that. One component, four props, no dependencies.

Building tablesalt: a CSV agent where the answer IS the UI
tablesalt is an in-browser data agent. You drop a CSV, ask a question, and the agent renders the answer as the right kind of UI: a chart, a stat card, a table, or a list. No chat bubbles.

Building grant-pilot: a multi-turn agent that orchestrates three sub-agents over real federal data
A multi-turn agent that finds federal grants for small businesses and nonprofits. A planner orchestrates three sub-agents (discovery, eligibility, drafter) over real federal data, with a hard daily budget cap, atomic spend reservation, and a planner that never throws. Here's what I built and what shipping it taught me.
