Logbooks, notebook computing for coding agents

Logbooks adapts some ideas from structured notebook computing environments like nbdev and Papermill for Claude Code and other coding agents. This is a pattern I found myself repeating across a few recent projects, and thought I'd try to formalize it and reflect on it a bit. Research and scientific computing rely on notebooks because they often consist of complex sequences of one-off variations, and demand both flexibility and reproducibility.

Logbooks adapts some ideas from structured notebook computing environments like nbdev and Papermill for Claude Code and other coding agents. This is a pattern I found myself repeating across a few recent projects, and thought I'd try to formalize it and reflect on it a bit. Research and scientific computing rely on notebooks because they often consist of complex sequences of one-off variations, and demand both flexibility and reproducibility. But my experience using Cursor and Claude Code with Jupyter has been quite poor. What I've found here is that creating a "notebook", naively, as a parameterized markdown file that is instantiated upon each execution, worked much better than I had expected it to, and I'm interested in figuring out what the limits of this approach are. I would welcome any ideas or feedback!
