marimo-pair is an open-source extension for marimo reactive notebooks that lets you drop AI agents directly into live, running notebook sessions. Unlike traditional AI coding assistants that only see static code, these agents can execute cells, inspect in-memory variables, read dataframes, manipulate UI components, and iterate on your actual live state — not a static snapshot. The tool plugs into Claude Code via a marketplace plugin and supports any agent implementing the Agent Skills standard. An agent that can see and run your notebook opens up genuinely new workflows: "explore this dataframe and tell me what's anomalous," "run this hypothesis test on the data already in memory," or "generate a chart for each of these 12 conditions." It's the difference between an assistant that reads your code and one that works alongside you in your actual environment. Marimo itself is already a compelling React-based replacement for Jupyter — every cell tracks its dependencies so the notebook is always consistent. marimo-pair makes that reactive model collaborative with AI, enabling a new style of human-AI pair programming where the agent shares your full computational context.

SkyPilot Research-Driven Agents is a new open-source technique and accompanying framework that dramatically improves autonomous coding agent performance by adding a literature-review phase before the coding loop begins. Instead of diving straight into code, agents first read relevant papers and competing open-source implementations, then develop a research-grounded plan before writing a single line. In a published benchmark, the research-driven loop produced a 15% speed improvement on llama.cpp inference with only $29 in total cloud compute spend — using SkyPilot to spin up and tear down cloud VMs for parallel agent tasks. The framework is open-sourced in the SkyPilot repository and works with any coding agent runtime including Claude Code and Codex. The insight is straightforward: coding agents fail less when they have domain context. A literature review phase that reads the top 3 papers and top 2 competing GitHub repos before touching the codebase gives agents the same contextual grounding a senior engineer gets from months on a project. The SkyPilot cloud orchestration layer makes the compute cost of running these longer-horizon agents tractable.
Reviewer scorecard
“The gap between 'AI sees your code' and 'AI runs in your environment with live data' is enormous for data science work. I've wasted hours explaining context to LLMs that could have just looked at the dataframe. This closes that loop completely.”
“+15% on llama.cpp for $29 is a remarkable return. The research-first pattern is something every senior engineer already does intuitively — formalizing it into the agent loop is obvious in retrospect. Add this to any performance-optimization agent workflow now.”
“Giving an agent the ability to execute arbitrary cells in a live environment with production data is a security nightmare waiting to happen. The v0.0.11 version flag means this is still early — wait until there's a proper permissions/sandbox model before trusting it with real data.”
“The llama.cpp benchmark is a well-studied domain with abundant public literature — ideal conditions for a research-first approach. Try this on an obscure internal codebase with no papers to read and see what happens. The gains likely don't generalize as cleanly.”
“Reactive notebooks with agent context sharing is the architecture for AI-native scientific computing. This isn't just a tool — it's a prototype for how researchers will work with AI in 2027: not prompting from outside, but collaborating inside the live computational environment.”
“This is how agents get to expert-level performance in specialized domains — not just bigger models, but better information-gathering architectures. The research-first pattern will become standard for any agent doing non-trivial technical work. SkyPilot is just the first to publish the recipe.”
“For creative data analysis and visualization work, being able to tell an agent 'make this chart more readable' while it can actually see the rendered output is a quantum leap over copy-pasting code. Marimo's reactive model makes iterating on designs feel instant.”
“Not directly relevant to creative workflows, but the underlying principle — give agents context before asking them to create — absolutely is. Interesting to watch how this pattern evolves outside pure coding tasks.”
