pixi 0.76 can now run standalone python scripts in isolated, on-demand environments. dependencies live inline via PEP 723, like uv supports, but pixi can layer on conda and system dependencies too. fun to build this with @prefix.dev folks. coming to a @marimo.io notebook near you SOON.

marimo.io/pair has a fresh landing page and some updates! for the launch, i wrote about why we moved beyond mcp and how we gave the agent @marimo.io itself as a tool through python.

marimo pair — a thinking canvas for you and your agent

Give your agent a marimo notebook. The ease of chat, the rigor of software.

i’m @pycon.us with the rest of the @marimo.io team. come say hi!

got to talk through more of the engineering behind marimo-pair, writing skills, and interactive visualization. thanks for having me on! www.youtube.com/watch?v=K791...

It was great having @manzt.sh on the show from @marimo.io! Thanks for sharing what you’ve been working on for data scientists and notebook users.

building marimo pair has been a new kind of engineering (for me). a lot changes when the consumer of your api is a model rather than another program. we’ve shipped “breaking” changes without upgrading or migrating the skill. the models just figure it out. hope you like it :)

Introducing marimo pair: a skill that drops agents like Claude Code inside a running notebook, letting them read variables, run code, and manipulate UI elements. It also lets agents use marimo as a standalone REPL. youtube.com/watch?v=VKv... (1/n)

the latest release of the @marimo.io @vscode.dev extension adds LSP diagnostics for marimo rules multiple variable definitions and dependency cycles are flagged as you type:

some of the first things new users notice and love in @marimo.io are our opinionated formatters (e.g., our table for dataframes) for v0.20.0 I worked on one aimed at AI engineers: a rich formatter for @pytorch.org `nn.Module`

We've all seen dataframe spaghetti code out there. But the remedy ... is pretty easy: just start using the pipe method! The moment you see the `.pipe()` in action, you'll never want to write pipelines without it. See the reason why here: www.youtube.com/watch?v=J0P...

i’m used to hearing from strangers when my open-source "fails" them… this made my day

still lots to do... but we're cooking on a native @vscode.dev extension for @marimo.io notebooks
