  • Multi-agent parallel work
  • Cross-IDE / cross-repo workflows

Recommended options

Cursor

AI-first VS Code fork with agent mode, tab completion, and BugBot review. Mature pick if you want AI inside the editor.

Claude Code

How to switch from GitHub Copilot cleanly

Keep Copilot for in-editor completions; layer Agentastic for delegated multi-agent work — the two combine cleanly.

Common questions

Can Agentastic replace Copilot?

For completions, no. For delegated work where you ask "build feature X", yes.
