 **A local-first, provider-aware coding agent for the terminal.**
 
 Conduit began as a Go port of Claude Code. It still keeps that compatibility where it matters: Claude OAuth, Anthropic wire format, the familiar tool surface, project memory, sessions, plugins, and MCP. It has also grown into its own agent runtime: Conduit-owned config, multi-account switching, role-based model assignment, OpenAI-compatible providers such as Gemini, and local/MCP-backed models can all live in one TUI.
