GitHub Copilot Dynamic Workflows public preview: code-defined multi-agent orchestration across CLI, app, and SDK
GitHub’s 2026-10-01 Changelog launched Dynamic Workflows in public preview for Copilot CLI, the Copilot app, and the SDK: code-defined reusable orchestration (sequential/parallel steps, pause checkpoints, subagent cross-checks)—unlike Autopilot or /fleet, where Copilot invents the plan each run. CLI needs --experimental or /experimental on; available on all Copilot plans.
Key Takeaways
- Anchors: Oct 1 Changelog + docs concepts + how-to pages linked above
- Code defines steps/conditions/handoffs; agents handle judgment. Distinct from Autopilot and /fleet
- Surfaces: CLI workflow run + /workflows; App Workflows button; SDK/extension canvases; share via personal or repo extensions
- Limits: max concurrent/total subagents, timeoutSeconds, approx maxAiCredits; prompt > workflow code > personal defaults
- Public preview; CLI experimental flag; no published agent-bench deltas—don’t conflate with HydraFusion or Computer Use
