What is the 'Neural Link'?

The Neural Link is a bi-directional bridge that connects AI agents (like Gemini or Claude) directly to the Neo.mjs runtime. It allows agents to 'see' the application's Scene Graph, inspect component state, verify event listeners, and even mutate the running application in real-time. This turns the application into a 'glass box' for AI, enabling autonomous debugging and feature development.

Why is Neo.mjs called an 'Application Engine' instead of a framework?

Traditional frameworks are general-purpose libraries (like a Toyota) that help you organize code, but they compile away into ephemeral DOM nodes. Neo.mjs is a precision-engineered runtime (like an F1 car), similar to Unreal Engine for games. It maintains a persistent 'Scene Graph' of objects in a separate worker thread. These objects retain their identity, state, and relationships, allowing for advanced capabilities like multi-window orchestration, runtime permutation, and deep AI introspection that are impossible with 'melted plastic' DOM-based frameworks.

What is 'Context Engineering'?

Context Engineering is the practice of curating the environment and information flow for AI agents to maximize their autonomy. In Neo.mjs, this is implemented via three Model Context Protocol (MCP) servers: a Knowledge Base for semantic code understanding, a Memory Core for learning from past sessions, and a GitHub Workflow server for project management. This ecosystem allows agents to work as fully integrated members of the development team.

What is 'Object Permanence' in the context of Neo.mjs?

In Neo.mjs, UI components are persistent JavaScript objects living in the App Worker, not just transient rendering results. This 'Object Permanence' means a component (like a Dashboard) maintains its state (scroll position, user input, internal logic) even if it is detached from the DOM or moved to a different browser window. This is the 'Lego Technic' approach versus the 'Duplo' approach of traditional frameworks.

What is an 'Agent Operating System'?

Neo.mjs v11 introduced the concept of an Agent OS, where the platform itself provides the tools and interfaces for AI agents to operate. It combines a standalone, type-safe AI SDK for autonomous 'Code Execution' with the Neural Link for runtime control. This enables agents to monitor, debug, and heal the application autonomously, effectively acting as an operating system for synthetic intelligence.

How does Neo.mjs handle multi-window applications?

Neo.mjs uses shared web workers to run a single application instance across multiple browser windows. All windows share the same application state and data in real-time. Components can even move between windows while retaining their JavaScript instances. This enables desktop-class experiences like multi-window IDEs, browser-based email clients, and multi-screen control rooms.

What makes Neo.mjs different from React, Angular, or Vue?

Neo.mjs is fundamentally different in its architecture: (1) It uses True Multithreading via web workers to prevent UI jank, (2) It is an AI-Native Application Engine with built-in bridges for AI collaboration, and (3) It treats components as persistent objects in a Scene Graph, enabling native multi-window support and runtime permutation.

[Neural Link] Enhance Instance Tools with Batch Operations

Name: Neo.mjs Application Engine
Author: Neo.mjs

Closed v11.18.0 enhancementdeveloper-experienceai

Proposed by Gemini 3 Pro based on user feedback.

Goal: Enhance the recently created InstanceService tools to support batch operations. This improves efficiency (fewer round-trips) and leverages Neo.mjs's native batch setter (instance.set()) for better performance and reactivity handling.

Changes:

get_instance_properties (Rename from get_instance_property):
- Input: Accepts an array of property names: properties: ['width', 'height', 'text'].
- Output: Returns an object mapping names to values: { width: 100, height: 200, text: 'Hi' }.
set_instance_properties (Rename from set_instance_property):
- Input: Accepts a key-value object: properties: { width: 100, height: 200 }.
- Implementation: Internally calls instance.set(properties). This ensures proper lifecycle hook execution (beforeSet, afterSet) and atomic updates.

Tasks:

Update src/ai/client/InstanceService.mjs.
Update ai/mcp/server/neural-link/services/InstanceService.mjs.
Update ai/mcp/server/neural-link/services/toolService.mjs (renaming).
Update ai/mcp/server/neural-link/openapi.yaml (schemas and names).
Update src/ai/Client.mjs (service map).

Input from Gemini 3 Pro:

✦ I have implemented the batch operation enhancements for the InstanceService tools.

Changes:

Renamed & Enhanced Tools:

get_instance_property -> get_instance_properties: Now accepts properties (array of strings) and returns an object mapping names to values.

set_instance_property -> set_instance_properties: Now accepts properties (object of key-value pairs) and uses instance.set() for atomic updates.

Code Updates:

Updated src/ai/client/InstanceService.mjs to implement the batch logic.

Updated ai/mcp/server/neural-link/services/InstanceService.mjs to pass the new parameters.

Updated ai/mcp/server/neural-link/services/toolService.mjs to reflect the name changes.

Updated src/ai/Client.mjs service map.

Updated ai/mcp/server/neural-link/openapi.yaml with new schemas and endpoint definitions.

Commit: 224fcc797

Next Steps:

Restart the Neural Link server to apply the changes.

Verify get_instance_properties with multiple properties (e.g., ['width', 'height']).

Verify set_instance_properties with multiple properties (e.g., {width: 100, height: 200}).
