Anecdotally in my company we have observed a far lower incident and outage rate since we moved to complete Agentic coding.

The extra velocity has meant we move considerably faster than the product team, so a lot of that extra dev capacity has been channeled into improving our tests, verifications and automated review processes - so hardly anything is slipping through the gaps.

This is the opposite of what I expected when we started working this way. One of the concerns we as a team raised was that it would lead to more bugs and lower quality but after 6 months the opposite appears to be true
