INTRODUCING CUSTOM AGENTS

Summary from the TLDR AI newsletter

Google has introduced Custom Agents in Antigravity 2.0 and the Antigravity CLI, with the Antigravity IDE following shortly. Custom Agents are specialized, file-based configurations that define a particular role with its own scoped instructions, tools, and constraints. The system keeps users' active contexts clean, minimizes token overhead, and gives them a predictable partner for specific tasks. Custom agents don't replace skills and dynamic subagents - they just provide even more customizability for another level of optimization.
