Jev in practice: typed decisions, scoped authority
Tenuo Engineering ·September 21, 2026 Building safe agent delegation with Jev, LangGraph, and Tenuo TL;DR: safe-upgrade is a dependency upgrade agent built on Jev, LangGraph, and Tenuo. Jev turns repository evidence into typed probabilistic decisions. LangGraph carries those decisions through a durable workflow. Tenuo gives each resulting action a task-scoped warrant. The design rule: keep […]
The GitHub wiki is an anti-pattern
The “should I use the wiki or a docs folder on GitHub?” discussion comes up every 6 months or so, and following Shawn Wang’s three strikes rule I thought it was about time I wrote something down about it. The initial version of this post opened with “You can use the wiki or a docs […]
I Don’t Want the Details
A few months ago I was dragged into a call with my engineering counterpart and their boss (who happens to be our SVP of engineering). Something had gone wrong that shouldn’t have. Nothing catastrophic, but important enough that I was now on a call with an SVP. I started to explain how it happened when […]

Claude Code reads AGENTS.md only when telemetry is on
Claude Code 2.1.277 announced support for AGENTS.md. In a project with no CLAUDE.md, it is supposed to read AGENTS.md instead. I keep telemetry off in my shell, and in my repos the file never loaded. Issue #95690 explains why, and I added my own measurements to it. This post collects them in one place. Where […]

The darker side of being a doctor
I’m a surgeon. I’d like to think that I’m resilient and well adjusted, having gone through medical school and rigorous surgical training. I’ve been a doctor for 13 years and much of that period has been spent training to be as good a surgeon as I could ever be. I have great family support, a […]
Tokens Too Cheap to Meter
The price of using machine learning intelligence is decreasing by several orders of magnitude a year and shows no signs of slowing. We are likely to see LLMs integrated into every part of computing as infrastructure, not just as a product, in the next year or two. We are likely to see LLMs running locally […]
