HOW WE BUILT A SOFTWARE FACTORY TO DRIVE ASTRO'S GITHUB ISSUE COUNT TO ZERO

Summary from the TLDR Dev newsletter

The Astro team automated GitHub issue triage with isolated AI subagents running in GitHub Actions that reproduce bugs, diagnose root causes, and ship preview releases for reporters to verify. They drove open issues from 200+ down to about 30, with zero expected within a month. The pipeline works as a state machine driven by issue labels, and agent failures are treated as signals of underlying problems in the codebase like opaque abstractions or missing tests.
