Linear: AI Coding Made CI the Bottleneck
Linear rebuilt its CI pipeline after agents started generating changes faster than the system could check them. Without the fixes, tests would now take about 11 minutes instead of 5.5.
Linear rebuilt its CI system (the automated code verification pipeline) because agents started writing code faster than CI could process it. Without those changes, tests would take around 11 minutes today instead of the current 5.5.
CI became a bottleneck for me around the same time Claude Code became part of my daily work. Linear published specific numbers: switching to tsgo sped up TypeScript builds by 52–73%, and linting by 68%. I would take this breakdown as a checklist for my own CI.
