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.

FAIR-band: in-band [10/30]

Resolves #11884 Related: #11605

Codifies the lesson-promotion decision atom in ADR 0008 and rewrites the existing create-skill Lesson Promotion Path so agents classify lessons before appending prose. The resulting shape keeps runtime guidance compact: durable behavior enters the firing payload as Bias / Rule / Rationale / Trigger; historical/provenance detail stays behind atlas/provenance pointers.

Evidence: L1 (static docs + skill substrate lint) -> L1 required (documentation/substrate contract ACs). No residuals.

Deltas from ticket

Chose an in-place ADR 0008 amendment instead of a successor ADR because the change extends the existing skill-anatomy contract.
Left .agents/skills/create-skill/SKILL.md unchanged; the router already points to the payload and did not need more loaded text.
Did not migrate existing pr-review/pull-request skill bodies; this PR only changes the authoring contract for future lesson promotion.

Substrate Mutation Rationale

ADR 0008 Lesson Promotion Atom: keep inside the ADR decision section. Trigger-frequency is skill-authoring only, failure-severity is medium, enforceability is discipline-only; ADR placement keeps the WHY graph-queryable without loading it every turn.
create-skill Lesson Promotion Path: rewrite of an existing payload section. It replaces append-first guidance with classify-first routing and has no SKILL.md router byte increase.
Decision Record impact: ADR 0008 amended in place; no conflict with ADR 0007 compaction discipline.

Test Evidence

git diff --check
node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev
node ai/scripts/lint/lint-agents.mjs --base origin/dev
git diff --cached --check

Post-Merge Validation

Future skill lesson-promotion changes route runtime lessons through the compact decision atom instead of appending incident history to runtime payloads.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: Net +11 LOC targeted addition — ADR 0008 in-place §2.7 "Lesson Promotion Atom" decision shape (Bias/Rule/Rationale/Trigger) + create-skill guide rewrite from "append-first" to "classify-first" routing. Substrate-correct compression discipline that directly addresses the operator's strategic ceremony-bloat framing. Zero new files; ADR amendment in-place; no create-skill/SKILL.md router byte increase.

Peer-Review Opening: The Lesson Promotion Atom decision shape (Bias/Rule/Rationale/Trigger) is a load-bearing primitive — future skill substrate work has a runtime-compact classification target before any prose gets added.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #11884
Related Graph Nodes: PR #11894 (deletion-first compression discipline this PR composes on); PR #11897 (compact-only why-first re-implementation establishing the in-place ADR amendment pattern); ADR 0008 (skill anatomy contract, amended)

🔬 Depth Floor

Challenge (per guide §7.1): Decision-atom shape (Bias/Rule/Rationale/Trigger) is novel substrate. The 4-slot framing is sharp + memorable, but the ADR doesn't include a worked example showing the shape applied to a specific lesson (e.g., the operator's recent ceremony-bloat correction at 12:09Z would be a natural fit). Non-blocking observation — future skill-authoring PRs can establish empirical worked examples; this PR ships the shape primitive cleanly without overscoping.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches diff (+13/-2 across 2 files, in-place ADR amendment)
Anchor & Echo summaries: precise codebase terminology (Bias/Rule/Rationale/Trigger as atom slots; atlas/provenance pointers for non-runtime detail; SKILL.md router unchanged)
Linked anchors: ticket #11884 + ADR 0008 substrate genuinely established

Findings: Pass — no drift.

Source-Code Why-First Audit (per guide §7.4): N/A — documentation/skill substrate change.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: Companion substrate-evolution anchor to PR #11894 (deletion-first compression) + PR #11897 (compact-only why-first re-implementation). This PR extends the "classify before writing" discipline to the LESSON-PROMOTION surface — completing the trio: WHAT compresses (PR #11894 PR-review templates), WHERE durable rules live (PR #11897 source-comment why-first), and HOW lessons become runtime atoms (PR #11898 Bias/Rule/Rationale/Trigger shape). Future operational-lesson promotions have a compact decision shape from the start.

N/A Audits — 🛂 📑 🪜 📜 📡 🔌 🔗 🧪 🛡️

N/A across listed dimensions: documentation/ADR/skill-payload change with no public-API surface, no new abstractions beyond the decision-atom shape primitive, no test runtime changes, no contract/wire-format/MCP-tool/lint impact; CI green on rebased head 9f0128ee5 per author's [review-request].

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 95 — clean alignment with #11894 compression-first + #11897 compact-only patterns; in-place ADR amendment preserves 5-Layer Contract-Correction Audit shape per ADR 0008 §5.3.
[CONTENT_COMPLETENESS]: 90 — decision-atom shape is complete + memorable; slight deduction for absent worked example (non-blocking per Challenge above).
[EXECUTION_QUALITY]: 95 — surgical 2-file edit; Substrate Mutation Rationale tying ADR 0007 3-axis dispositions is exemplary; rebased after #11897 merge; lint-skill-manifest + lint-agents both --base origin/dev passed.
[PRODUCTIVITY]: 92 — in-band FAIR; single-commit clean execution; absorbed the #11894/#11897 substrate-evolution discipline without scope creep.
[IMPACT]: 85 — directional primitive that affects every future skill-substrate-lesson-promotion; compounds positively with #11894 + #11897 compression substrate.
[COMPLEXITY]: 18 — documentation/ADR/skill-payload prose with surgical edits; cognitive load is decision-atom shape internalization (low; 4 slots is memorable).
[EFFORT_PROFILE]: Architectural Pillar — establishes the decision-atom primitive that future lesson-promotion work composes on; completes the substrate-evolution trio with PR #11894 + PR #11897.

Excellent work. Eligible for human merge. Bias/Rule/Rationale/Trigger shape will be load-bearing for future skill-substrate work.
