The trick: Moved Ruler

AI now writes half of what goes into Linear.

Teams tripled their pull requests. Linear itself says it has no idea if any of that helped.

Issue 1524 August 20268 receipts4 min

AI now writes just under half of everything created in Linear, teams with a coding agent tripled weekly pull requests from 21 to 65, and total product development time increased anyway.

Before you read on. Your call?

Linear's own data report backs the first two numbers, verbatim. The third doesn't exist in it. What actually rose is "time spent creating, triaging, and commenting," Linear's own words, for time logged inside the issue tracker, not time-to-ship. Linear has never published a cycle-time or time-to-merge number in this report.

The twist

Linear says it plainly: "we have no way of knowing whether this increased output led to positive business outcomes." A separate dataset of 8.1 million pull requests found AI-assisted PRs merge at roughly half the rate of human-written ones, meaning tripled PR volume isn't tripled delivered work. Three more PRs a week and no faster ship date is not a contradiction. It's coordination overhead with better marketing.

Say this in tomorrow's meeting“Linear's own report says it can't tell if any of that extra output was worth anything. The "teams ship slower" headline is doing work Linear's data doesn't do.”

Context web.archive.org: AI prs merge at just 32.7%, which is less than half of that rate.
Context faros.ai: Volume is up, quality is down, and the gap between the two is widening as adoption deepens.
Context web.archive.org: manual PRS merge at about 80, 84 point half percent, so about 84% of all the unassisted prs that are open get merged
