Field notes
The Vivary blog.
Why this exists, what it's for, and what we're learning about agent harnesses, agent-native workspaces, and running it all locally.
Run Vivary with local models
Vivary is plain files and standard-library CLIs, so it doesn't care where the model runs. Here's how to use it entirely with local models, and how to get good results from smaller ones.
Harnesses, explained
The model writes the words. The harness decides what the model sees, what tools it can use, and what happens to its output. Here's what that means, and why Vivary stays harness-neutral.
What is an agent-native workspace?
A folder of Markdown is not an agent-native workspace. The difference is structure an agent can navigate, verify, and trust, and it changes how reliably an agent can work.
Why I built Vivary
Every serious AI-agent project ends up rebuilding the same five things by hand. Vivary is what happens when you stop rebuilding them and ship the layer instead.
