100-word summary
OpenAI released Symphony, an open-source spec that turns every Linear ticket into an autonomous coding agent. Internally, the system delivered 500% more merged pull requests within three weeks. Each agent runs continuously in its own workspace, automatically restarting if it crashes and picking up new work without human prompting. The breakthrough isn't technical sophistication but architectural simplicity: tickets now represent larger chunks of work instead of single PRs, so agents can ship multiple pull requests or run analysis tasks unsupervised. Non-engineers can now create tickets that spawn working code, bypassing traditional developer bottlenecks. Symphony is a reference implementation, not a maintained product, which means teams will need to adapt it...

Why it matters
Symphony is a reference implementation, not a maintained product, which means teams will need to adapt it rather than install it.
