Now that I have my legacy CodeIgniter 2.1 environment set up, I was able to work with Claude.AI again today to do some problem solving with it. Today’s experiment was using some post controller hook based benchmark logging to diagnose a slow controller action.

I used Claude.AI to build a controller and view that summarized statistics for the benchmarking and share the results with the rest of the team. I knew enough of the shape of what I was looking for to get an index page with summary daily stats with an SVG graph and daily views with hourly stats. I had a few security concerns with how Claude.AI put this together, but through prompts and reading through code - was able to get something suitable for use in our environment.
