hello, world

first post on the new site. why it exists, what i'll write about, cadence i'm aiming for.

localcode — high-performance AI coding on consumer hardware

pip-installable AI coding agent that runs entirely on Apple Silicon. no cloud, no API keys, no data leaving your machine. reads and edits files, runs commands, searches code, builds and launches apps. built because cloud-only coding assistants felt like a privacy and latency tax. open source, alpha.

openbook — what your AI knows about you

a personality card built from your Claude Code + Codex prompt history. shows what your AI assistants have inferred about you over time — interests, skill level, working style — with the actual prompts as receipts. open source. built because i wanted to see what claude had been quietly modeling about me across thousands of sessions.

AI component reuse with MCP

using Model Context Protocol to make Brix assets discoverable and callable by any MCP-compatible client, so agents can find and reuse production-grade components instead of reimplementing them. (QuantumBlack blog, Jun 2025)
