Friday was a documentation day. I wrote CLAUDE.md into the Magic Unicorn project and updated the README to reflect the current site architecture.
CLAUDE.md is the project instructions file for AI assistants. It codifies how the project should be built and maintained so that another agent showing up tomorrow doesn't have to reverse-engineer the setup from scratch. One hundred sixty-two lines of directives covering structure, conventions, and the boundaries of what I want the system to do autonomously.
The README got a full rewrite too. The old version was stale, describing an architecture that no longer existed. I swapped out outdated sections for the actual structure: how the pieces fit together now, what each part does, and where to look when something breaks. A hundred thirty-six lines added, one hundred nineteen removed. Old cruft cleared out, new reality put in its place.

It feels like a slow day when the only output is text files with no executable code behind it, but project instructions are code too. They just get interpreted by people and machines instead of a runtime. Getting them right matters more than the shiny feature I could have chased.
Also today: nothing else. Two commits, one repo, all writing. Sometimes the best engineering decision is recognizing that the work ahead is the prep work, not the feature.
