Engineering notes on local-first AI, developer tools, agent UX, protocol design, creative technology, and self-hosted infrastructure. Longer-form pieces live here.
When agents run locally against quantized models, the assumptions behind chat-based interfaces break down. This note explores what kind of UX actually works when latency is low, models are smaller, and the developer needs full observability into the agent loop.

Lessons from designing Relay: how protocol translation between OpenAI/Anthropic schemas and local inference servers reveals the subtle differences that break agent behaviour — from streaming semantics to tool-call accumulation strategies.

The terminal is an underrated medium for AI interfaces. This note covers the design decisions behind Synax's TUI — how to render real-time agent state without overwhelming the developer — and why transparency matters more than magic when models are local and imperfect.
