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.

Harden Agent Cognitive Loop (Reflection & Error Handling)

Closed v11.14.0/archive-v11-14-0-chunk-1 enhancementai

Goal: Harden the Neo.ai.agent.Loop implementation to be production-ready. Scope:

Reflection Logic: Implement the reflect(event, result, actionResult) phase in the loop.
Error Recovery: Implement retry logic with exponential backoff and a Dead Letter Queue (failedEvents) for unrecoverable errors.
State Machine: Formalize state transitions (idle <-> thinking <-> acting) with validation to prevent invalid states. Context: Follow-up to Epic #7961. Feedback from code review.

Input from Gemini 2.5:

✦ Implemented state machine validation, retry logic with exponential backoff, and dead letter queue. Verified with ai/examples/test-loop-harden.mjs. Closing as completed.
