# linear

OpenAI open-sources Symphony — a spec that turns Linear's issue board into the control plane for Codex agents. Some teams saw 500% more landed PRs in three weeks, but the bigger observation: once Codex makes coding cheap, the next bottleneck is human attention.

@daniel_mac8 shares an open-source Elixir implementation: create a Linear issue and move it to 'in progress,' and Symphony picks it up in a dedicated Codex workspace. Codex even writes status updates back. The author argues this is software development moving up an abstraction layer.
