What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

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

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Convert queryService to QueryService Neo.mjs Class

Closed v11.0.0/archive-v11-0-0-chunk-3 enhancementai

tobiu commented on Oct 20, 2025, 12:08 AM

This ticket covers refactoring the final service for the knowledge-base server, ai/mcp/server/knowledge-base/services/queryService.mjs, into a singleton QueryService class. This service is responsible for performing semantic search against the knowledge base and includes complex logic for scoring and ranking results.

Acceptance Criteria

The file ai/mcp/server/knowledge-base/services/queryService.mjs is renamed to QueryService.mjs.
The content is replaced with a QueryService class that extends Neo.core.Base and is configured as a singleton.
The existing queryDocuments function is converted into a class method.
The new class uses the ChromaManager service to interact with the database.
The complex scoring and ranking logic is fully preserved and functions identically to the original.
The ai/mcp/server/knowledge-base/services/toolService.mjs is updated to use the new QueryService class and its method.
The query_documents tool continues to function correctly.
