The Dennis Yang interview matters because it shows a coding-agent interface being used for PM work, not only engineering tasks.
The workflow spans PRDs, Jira tickets, Confluence-style documentation, and responses to coworkers. That is the interesting part: the agent surface is useful because the work is artifact-shaped and context-heavy, even when the artifact is not code.
For New Runtime, this supports the broader shift from coding tool to workbench. The same loop keeps appearing: gather context, draft a structured artifact, revise against constraints, and hand the result back into the team's existing system.
