I moved my entire Claude Code environment into a containerized setup. Now I can run in yolo mode with more peace of mind. The exercise also forced me to deal with how many of my workflows had hardcoded paths and implicit dependencies.
Containerized everything. The single biggest change this week. All my Claude Code workflows now run inside a devcontainer. Still working out some rough edges.
Data visualization as a quality standard. I created my own version of Tufte principles as a skill that agents can reference during notebook development. Then extended it with a few other profiles from people whose work I have on my bookshelf (Bertin, Few, Wilkinson, Cairo). Skills are not a moat.
Data marketplace guides as agent context. Built more structured guides for public data models so agents can reference schema, lineage, and best practices during analysis projects.
Programmatic slide decks. Rolled my own HTML to PPTX converter to produce presentations directly from notebook data. Charts export as SVGs, data tables render cleanly, and the whole thing rebuilds from source. Still fiddly (font sizes, annotation placement), but the goal is to never touch PowerPoint or Google Slides again.
The Tufte Test — Randal Olson encoded Tufte’s visualization principles into an API, pointed an AI agent at it, and watched it self-correct from a generic chart to a genuinely good one in two prompts. Also learned that he is a moderator of my favorite dataviz subreddit (r/dataisbeautiful).
Lenny’s open data play — Lenny released his entire newsletter archive (350+ posts) and podcast transcripts (300+ episodes) as AI-friendly Markdown, plus an MCP server. Damn. Now I need to read everything.
gstack — Garry Tan’s “run your entire company” stack. Pretty baller that he is doing this while also running YC full-time.
