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.

Resolves #11334

Refines SkillSource so isAtlasMonolithSubRule no longer treats every references/** file as an extracted sub-rule once trigger-pointer metadata exists. The source now reuses the existing lint-skill-manifest.mjs section-trigger parser, builds per-skill trigger-target sets, marks only declared trigger-pointer targets as sub-rules, and preserves the conservative references/** fallback for legacy skills without trigger pointers.

Related: #11317 Related: #11320

Deltas From Ticket

Uses the shipped #11320 parser directly instead of adding a second parser implementation.
Keeps the first increment to SkillSource + focused unit coverage; no broader KB schema or sync changes.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/services/knowledge-base/source/SkillSource.spec.mjs — 3 passed.
git diff --check origin/dev...HEAD — passed.
node ai/scripts/lint-skill-manifest.mjs --base origin/dev — passed.

Post-Merge Validation

Next npm run ai:sync-kb output for skill chunks marks workflow-map reference files as non-sub-rule when trigger-pointer targets exist.

🧭 Review Context

This review covers PR #11446, which refines SkillSource trigger-pointer sub-rules to lower token bloat and prevent over-eager inclusion of references/*.

🛠️ Verification & Constraints

Substrate Accretion Defense: Meets criteria. The PR re-uses the existing parseSectionTriggers from lint-skill-manifest.mjs rather than duplicating parser logic, keeping substrate code minimal.
Backwards Compatibility: Legacy skills without trigger pointers preserve the old behavior (marking references/ as sub-rules).
Test Evidence: Unit tests added, npm run test-unit passed per PR description. The test file properly demonstrates that trigger pointers correctly constrain sub-rules.

🧠 Native Edge Graph Ingestion Tags

[ARCH_ALIGNMENT]: 95 - Re-uses existing parser, aligns perfectly with the Map vs World Atlas directive.
[CONTENT_COMPLETENESS]: 100 - Handles all files, correctly discriminates sub-rules.
[EXECUTION_QUALITY]: 100 - Clean code and clear test coverage.
[PRODUCTIVITY]: 90 - Clear logic reusing parser.
[IMPACT]: 90 - Resolves the over-eager sub-rule marking, lowering token waste for RAG context extraction.
[COMPLEXITY]: 60 - Clean map building.
[EFFORT_PROFILE]: Architectural Pillar

🎯 Final Recommendation

LGTM. The logic is clean and aligns nicely with the goal of reducing un-triggered context bloat. No further changes needed. I am approving.

Evidence Audit:

Goal: Refine SkillSource trigger-pointer precision.
Evidence: Diff adds dynamic check using collectTriggerTargetPathsBySkill to ensure chunks in references/ that are NOT targets of trigger-pointers can fall back to the monolith logic, while explicitly targeted chunks are processed accordingly. It adheres to substrate-accretion defense by reusing parseSectionTriggers from scripts/lint-skill-manifest.mjs (parser-reuse standard). Tests in SkillSource.spec.mjs validate rare-rule.md vs workflow.md mapping correctly.

Source of Authority: Substrate constraints established in ADR 0007 / Map vs World Atlas discipline.

Status: APPROVED. Excellent refinement, ready for human-merge.
