Linear's engineering team reworked its continuous integration system after the CTO flagged rising costs and slow test cycles, a problem intensified by developers using AI agents to write code far faster than CI could validate it. By switching to faster third-party runners and adopting the native TypeScript compiler tsgo, along with reducing redundant setup and optimizing gating jobs, Linear cut pull request wait times from over six minutes to just over five and roughly halved runner time per test, even as its test suite nearly quadrupled in size.

A software developer recounts that their business partner used an AI coding assistant to build an entire payments backend module in a single day, then submitted a 5,236-line pull request without testing it. The developer found the endpoints didn't actually work and that documentation was riddled with obvious AI-generated filler, while missing critical details like where to obtain API keys.

Opslane is a new open-source platform that records user sessions to catch bugs beyond crash reports, including silent UX failures like unresponsive buttons or abandoned forms. It ranks issues by how many users are affected, investigates the highest-impact ones, and automatically opens verified pull requests when it can confirm a fix works in a sandbox environment. The system integrates with coding agents via an MCP server and delivers a daily Slack digest summarizing what broke and what's ready to merge.
