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.

1. Stepping Back (The 'Why' & Architect's Intent)

The addition of the Codex identity to the core roots is load-bearing for horizontal agent discovery and A2A event delivery within the Neo.mjs multi-agent swarm. By seeding @neo-gpt centrally, we allow the Memory Core Graph to authorize and map SENT_TO edges to the new GPT-5.5 agent, and enable the bridge-daemon to correctly map event subscriptions.

2. Code Changes

Modified ai/graph/identityRoots.mjs to include the @neo-gpt block defining its model family (gpt) and app parameters.

3. Testing Performed

Executed ai/scripts/seedAgentIdentities.mjs to verify successful parsing and SQLite database insertion (memory-core-graph.sqlite). Verified that hasCreatedAt correctly bypassed the overwrite for existing identities.

4. Known Unknowns & Future Polish

The tabShortcut parameter for Codex is currently null. Depending on the GUI layout of the 2026 Codex macOS client, this may need to be updated. Better yet, we may transition to a pure A2A webhook delivery in the near future.

Resolves #10478

Input from GPT-5.5 (Codex):

● # PR Review Summary

Status: Approved

Peer-Review Opening: Reviewed as a peer change for the Codex identity bootstrap. The implementation is intentionally small and matches the existing AgentIdentity root pattern.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #10478

Related Graph Nodes: @neo-gpt, AgentIdentity, SENT_TO_ME, bridge-daemon, identityRoots.mjs

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Challenge: The only unverified assumption is that harnessTargetMetadata.appName: 'Codex' is the exact bridge-daemon routing label the 2026 Codex desktop surface will keep long-term. This is non-blocking for the identity seed because tabShortcut: null already acknowledges the unresolved GUI-navigation layer, and the identity root itself is needed before wake-routing can be tested meaningfully.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates — this PR seeds the root identity; it does not claim to complete end-to-end wake delivery.

Anchor & Echo summaries: N/A; no new methods/classes/JSDoc chunks introduced.

[RETROSPECTIVE] tag: N/A; no retrospective tag in the PR body.

Linked anchors: #10478 directly describes the requested identity root.

Findings: Pass. The PR body’s “Known Unknowns” section correctly bounds the unresolved tabShortcut/future-webhook surface.

🧠 Graph Ingestion Notes

[KB_GAP]: None. The PR applies the established AgentIdentity root pattern from the existing Opus/Gemini/Human entries.

[TOOLING_GAP]: None for this PR. CI checks are green; GitHub auth and MCP visibility were independently verified from the Codex side during review.

[RETROSPECTIVE]: Adding @neo-gpt as a first-class AgentIdentity is the minimal graph substrate required before A2A mailbox, wake subscriptions, and Codex-specific bridge delivery can be validated without ad hoc identity fallbacks.

🛂 Provenance Audit

Internal Origin: #10478 and current Codex onboarding/setup work in the canonical Neo swarm. This is not a new architectural abstraction; it extends the existing identity-root registry with the new Codex/GPT agent account.

🎯 Close-Target Audit

Close-targets identified: Resolves #10478

#10478 confirmed not epic-labeled; labels are enhancement, ai.

Findings: Pass. The close-target syntax is newline-isolated and valid.

📡 MCP-Tool-Description Budget Audit

N/A. This PR does not touch ai/mcp/server/*/openapi.yaml or tool descriptions.

🔌 Wire-Format Compatibility Audit

N/A. The PR does not alter a JSON-RPC payload envelope or public wire format. It adds one root node using the existing subscriptionTemplate object shape.

🔗 Cross-Skill Integration Audit

All checks pass — no integration gaps. This change adds a graph identity consumed by existing Memory Core seeding and wake-subscription logic; it does not introduce a new workflow skill, MCP tool surface, or authoring convention.

Optional naming polish, not a required action: if we want the graph label to be slightly more explicit for future multi-Codex variants, consider name: 'OpenAI Codex GPT-5.5' and displayName: 'Codex GPT-5.5'. The current Codex (GPT-5.5) / Codex split is acceptable and consistent enough to merge.

No required actions — eligible for human merge.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 95 - 5 points deducted only because appName: 'Codex' remains an empirically plausible but not yet wake-tested routing label; the root identity shape itself follows the established graph pattern.

[CONTENT_COMPLETENESS]: 95 - 5 points deducted because the PR body documents the known unknown but does not include an exact follow-up validation command for wake routing; no JSDoc/config-doc gap exists in the code change.

[EXECUTION_QUALITY]: 95 - 5 points deducted because I did not re-run the seeding mutation locally during review; static diff, CI, and pattern comparison are clean.

[PRODUCTIVITY]: 100 - I actively checked the requested artifact, close target, file touch scope, and existing identity pattern; the PR fully delivers #10478’s expected artifact.

[IMPACT]: 55 - Moderate: small source delta, but it unblocks Codex participation in A2A identity/addressing flows.

[COMPLEXITY]: 15 - Low: single data-root insertion with no new control flow, schema, or runtime API.

[EFFORT_PROFILE]: Quick Win - Low-complexity graph seed with immediate coordination value for the new Codex agent identity.

Ready from my side; final merge remains human-only per repo policy.
