Who owns this file?
Our template for new Shopify projects contains no theme code at all, and the most useful thing in it turned out to be the part that says which files we own, which ones belong to the client, and which ones should never have been copied in.
It's never the prompt
The prompting turns out to be the least interesting part of my Claude Code setup, and most of what's actually doing the work is a handful of files I wrote once and then stopped thinking about.
Keep the last three
How our Shopify deploys at work moved off DeployBot and into one repo of shared GitHub Actions workflows, and the backup cleanup that took three wrong versions before I stopped overthinking it.
Exit 0 means allow
Porting an internal Claude Code safety tool from Linux to macOS took about six weeks, and nearly every failure I found on the new platform failed in the permissive direction while printing a checkmark on the way out.
Blank on purpose
A client's homepage sat blank for a second and a half before it painted anything, and the code holding it there came from the tool they had bought to make the site convert better.
It wasn't just my machine
Getting the local environment running on my Windows machine took most of my first week and hours of the lead developer's time, and I spent all of it assuming the problem was me.
