# Agent capabilities are being distributed across specialized workers and shared tool interfaces

## Retrieval answer

Antigravity adds custom agents that can act, verify, and run in parallel, while Spotify’s Portal routes bulk reads and predictable generation to worker modes and keeps high-judgment work on a frontier model.

Antigravity adds custom agents that can act, verify, and run in parallel, while Spotify’s Portal routes bulk reads and predictable generation to worker modes and keeps high-judgment work on a frontier model. The MCP roadmap’s emphasis on stateless servers and pre-connection discovery adds shared infrastructure for connecting capabilities. Builders can compose specialized agents and tools instead of routing every task through one general agent.
