What to watch — open questions

  • Does the harness runtime's now-stable orchestration patterns extend beyond Microsoft's own ecosystem (Copilot, Claude Agent SDK) to other agent frameworks?
  • Do independent "harness" projects like Go Micro converge toward Microsoft's terminology and APIs, or does the term stay contested across vendors?
