AutoXPP for Codex

Autonomous D365 Finance & Operations development engine — for OpenAI Codex.

AutoXPP brings AI-powered X++ development to Codex: X++ coding, Visual Studio 2022 build & deploy, test authoring and execution, and browser automation — delivered as a Codex plugin of reusable skills backed by the AutoXPP MCP server.

This is the Codex edition of AutoXPP. The skill content is kept in sync with the Claude Code edition; only the packaging and a few tool-specific skills differ.
