My session with Claude Code and PRDs
A beach day bundles light, movement, immersion and attention into one unusually easy package. Here is what the evidence supports, and what it does not.
One panel flagged my creatinine above range and put my eGFR at 74, which reads as stage 2 kidney disease. The test that settles it came back this morning. Same kidneys, same morning, 47 points apart.
Every new Claude model now embeds an invisible statistical mark in its text output, worldwide. Here is how it works, why code is the worst case for it, and the asymmetry nobody is going to read carefully enough.
The most expensive code your agents write is clean, tested, documented and unnecessary. A working 2026 protocol for finding what to remove, before it hardens into architecture.
