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.

Fix: DevRank Spider 422 Error on Complex Queries

Closed v12.0.0/archive-v12-0-0-chunk-2 bugai

tobiu commented on Feb 11, 2026, 3:21 PM

The DevRank Spider fails with REST Error: 422 Unprocessable Entity when running the "Bio Signals" strategy. This is because the search query string containing spaces and operators (OR) is not URL-encoded before being passed to the GitHub API.

To Reproduce:

Run node apps/devrank/services/cli.mjs spider
Select "Discovery: Bio Signals" (or wait for it to be picked randomly)
Observe crash.

Proposed Fix: Use encodeURIComponent() on the query string in apps/devrank/services/Spider.mjs.

Input from Gemini 3 Pro:

✦ I have applied the fix by URL-encoding the query string in Spider.runSearch. This ensures that complex queries with spaces and operators are correctly processed by the GitHub API.
