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.

Performance: Remove avatarUrl convert overhead in DevIndex Contributor Model

Closed v12.0.0/archive-v12-0-0-chunk-4 enhancementaiperformance

tobiu commented on Feb 26, 2026, 3:33 PM

The DevIndex backend spider engine fetches raw avatar_url from the GitHub REST API. Previously, the DevIndex.model.Contributor was performing an expensive convert operation on instantiation to map this into a full URL format under the avatarUrl field.

To optimize performance for 50k+ records, this ticket removes the convert overhead. The model now maps the raw ID string into the avatarUrl field directly.

Consequently, the UI components (GitHubUser, GitHubOrgs, and ProfileContainer) have been updated to smartly detect if avatarUrl is a full HTTP string or just an ID, dynamically constructing the https://avatars.githubusercontent.com/... link at render time. This maintains compatibility for both the highly optimized DevIndex app and general framework usage.

Changes:

apps/devindex/model/Contributor.mjs: Removed convert overhead for avatarUrl and organizations.
apps/devindex/view/home/ProfileContainer.mjs: Updated getAvatarUrl() to handle raw IDs.
src/component/GitHubUser.mjs: Updated URL construction logic.
src/component/GitHubOrgs.mjs: Updated URL construction logic.
src/grid/column/GitHubUser.mjs: Mapped avatarUrl from record.avatarUrl.

Input from Gemini 3.1 Pro:

✦ Successfully completed and pushed to the dev branch in commit 29bb47d1e.

Summary of Completion:

Reverted changes to apps/devindex/services/Updater.mjs to protect the backend spider logic.

Removed convert overhead for avatarUrl and organizations array inside DevIndex.model.Contributor.

Updated apps/devindex/view/home/ProfileContainer.mjs to resolve avatarUrl from raw IDs.

Refactored src/component/GitHubUser.mjs and src/component/GitHubOrgs.mjs to accept both raw IDs and full URL strings, ensuring backwards compatibility for other applications.

Adapted src/grid/column/GitHubUser.mjs to fetch avatarUrl.
