AutoXPP™ is a professional-grade autonomous execution engine for X++ development. It parses requirements, decomposes tasks, generates code, builds, deploys, validates, and iterates — deterministically, inside your IDE.

This is the same discipline experienced architects enforce manually — now executed autonomously.

What AutoXPP Does

An autonomous runtime that handles the full development loop

Requirement Parsing

Understands what you need built and decomposes it into structured development tasks aligned with D365 F&O patterns.

Code Generation

Generates production-ready X++ code, metadata artifacts, and configurations following verified platform patterns.

Build Execution

Triggers builds and catches compilation errors before they reach your environment.

UDE Deployment

Deploys to your Unified Developer Experience environment automatically.

Test Validation

Runs validation against expected behavior and catches regressions.

Iterative Correction

When validation fails, diagnoses the root cause and corrects — repeating until the requirement passes.

Engine Capabilities

What the autonomous runtime includes

IDE-Native Execution

Runs directly in your development environment. No cloud dependency for the execution loop.

D365 F&O Pattern Library

Verified patterns for forms, posting, batch processing, security, extensions, and more.

Deterministic Orchestration

Structured task execution with explicit decision trees, not probabilistic guessing.

AI Client Compatibility

Works with Claude Code, Cursor IDE, and other AI coding clients that support agent integration.

Continuous Engine Updates

Patterns and orchestration logic evolve monthly. Updates are delivered automatically.

Private GitHub Repository

Subscribers receive access to the AutoXPP engine repository for IDE integration.

How AI Is Guided in Real X++ Projects

See how AutoXPP applies structured guidance to real D365 F&O development scenarios

Quality Gates

Enforced Development Guardrails

Agents pause before extending standard code, verify understanding of existing patterns, and follow standard implementations whenever possible. This prevents the common loop of guess-fail-debug-repeat.

Best Practices

Extension Decision Logic

AI agents analyze how standard code handles scenarios, whether standard patterns already solve the problem, and when deviations are justified. This ensures extensions align with Microsoft-recommended practices.

Smart Detection

AutoXPP-Enabled AI Coding

When enabled, AI agents detect the D365 F&O workspace structure, confirm required session variables, and apply engine guidance before generating or modifying code. This results in more accurate, context-aware X++ output.

AI Workflows

Error Diagnosis and Fix Workflow

Agents follow structured flows to assess whether root causes are known, apply fixes directly when patterns exist, and trigger knowledge acquisition when uncertainty remains. This avoids hallucinated fixes.

These examples represent real AutoXPP engine behavior during D365 F&O development sessions.
