Writing
Engineering notes from building Murmell
Four things we had to work out to run several coding agents on one directory, each written from the code that does it. The measurements are our own and are stated as such.
What stops Claude Code on its first launch in a container
The three prompts that block a fresh Claude Code agent in a container, measured through a real pty.
Reserving a file before you write it
Why several agents on one directory have to claim a path first, and what the server does when one of them does not.
The machine that runs the agents holds no secrets
Why the half of the server that executes model-written code is kept away from the database, and what the separation cost to build.
What we found when we put agents on a cloud sandbox
What a managed cloud sandbox platform allows and refuses, measured against a probe pool rather than read in a document.
