Agents can't read your mind. Air helps you provide them better context.
Type @ to mention specific files, folders, symbols or commits in your project.
Or select specific lines of code and click Add to Task to reference them to the agent.
Agentic AI speeds up code production, but the challenge is execution and control.
JetBrains Central is an open system for agentiс development across the SDLC, with governance, observability, and controlled execution.
Early access starts in Q2 2026.
