Claude Opus 4.5: bugs are almost non-existent

I’ve been coding with Claude Opus 4.5 almost daily for the last couple of months.

Today I found a genuine bug in the code (incorrect formatting of datetime values when integrating Orion transactions to Salesforce).

I actually had to stop for a minute and try to remember when I’d last seen a bug that Opus 4.5 created.

It pretty much just doesn’t happen.

Yes, I have to plan the work and maintain strict design and QA control. But with that in place, bugs are almost non-existent.

It’s quite something. 😳
