I left cmux for herdr at the start of June because its remote support did not fit how I work.

Most of my last couple of weeks have been spent on code reviews and planning.

I use Pi and Claude Code day to day, and I run them in two places.

TL;DR Each MCP tool puts a contract in the model’s context.

I disqualified a 30B vision model for being too slow, and I was wrong about why.

TL;DR A guaranteed JSON schema tells you the shape is right, not that the content is any good.

TL;DR A typed FastMCP tool takes a few lines.

The argument I keep hearing is that skills have made MCP servers redundant.

Specs rot for a reason: we link them to code by file path and line number, and code moves.

If you’re thinking about getting into software engineering right now, the vibes are terrible.

This post is for the mids, seniors, and principals trying to work out what our jobs look like now that the machine writes the code.

TL;DR Open weights didn’t catch the frontier in 2026, but they got close enough for most of the work I do day to day.

My personal coding setup is a remote Ubuntu box that I connect to via ssh.

I built a PR reviewer called lgtmaybe, which is the joke I wanted in the name before I’d even started writing the code.

A few things I’ve built or am still tinkering with. lgtmaybe # A PR reviewer that works with six model providers behind one --provider flag.

A few blogs and people worth your time.

The morning coffee, my first priority!
