Insight

Gemini CLI now enables a built-in “generalist” sub-agent by default, giving users an always-available, tool-rich delegate that runs with the main system prompt in non-interactive mode. This shifts delegation from opt-in to baseline: the CLI treats sub-agent execution as a normal workflow path, designed to keep the main session lean while offloading long or noisy tasks.

Evidence

  • The commit adds/updates the generalist agent definition with tool registry access and a non-interactive prompt configuration.
  • Registry tests now expect the generalist agent to be registered by default.

Why it matters

This is a product-level stance: Gemini CLI is signaling that “agent delegation” is no longer experimental; it’s a first-class, default capability. It also frames sub-agents as a performance tool — shrinking main context while letting a separate agent churn through heavy tasks.
