ray-x/copilot-agent.nvim

copilot-agent.nvim is a Neovim plugin that runs GitHub Copilot’s agentic runtime locally via a small Go HTTP service bridging to the official Copilot SDK. It’s aimed at Neovim users who want an agent (not just chat) that can read/write files, run terminals, search the web, and iterate autonomously while integrating with editor workflows. Key features: native tool execution through the SDK; four chat/oversight modes (ask, plan, agent, autopilot); session-aware permissions and persistent per-project sessions; repo-local agent/skill discovery (.github/agents, .github/skills); LSP-native code actions (fix, test, explain); state rewind (undo/restore to conversation points); streaming observability and integration with common Git plugins. Architecture: Lua UI talks to a Go HTTP service and an LSP helper. Compared to simple chat plugins or ACP bridges, it provides deeper Copilot SDK features at the cost of being Copilot-specific.
