# Lean Integration Protocol

> USE FOR: Cross-skill integration protocol defining how all 39 skills work together. Covers the complete lifecycle from document to proof to document, inter-cluster communication, workflow templates for common tasks, and the master orchestration patterns. Use when coordinating multi-skill workflows or diagnosing cross-skill issues. DO NOT USE FOR: any single-skill execution (use that skill directly); the review council itself (use @lean-review-council); the gateway (use @lean-gateway). TRIGGERS: integration protocol, skill integration, cross-skill, skill lifecycle, inter-cluster routing.

# SK-40: Integration Protocol

Defines how all skills in the project ecosystem work together as a coherent system.

---

## Routing

- **USE FOR:** Cross-skill integration protocol defining how all 39 skills work together. Covers the complete lifecycle from document to proof to document, inter-cluster communication, workflow templates for common tasks, and the master orchestration patterns. Use when coordinating multi-skill workflows or diagnosing cross-skill issues.
- **DO NOT USE FOR:** any single-skill execution (use that skill directly); the review council itself (use @lean-review-council); the gateway (use @lean-gateway).
- **TRIGGERS:** integration protocol, skill integration, cross-skill, skill lifecycle, inter-cluster routing.

## Workflow

1. Identify the cross-skill question: which skills, what data flows, which handoffs.
2. Pick the lifecycle section of the body matching the flow (document → spec → proof → doc, or council ↔ research).
3. Produce the integration recipe — explicit sequence of skill invocations + artifact handoffs.
4. Hand off: to `@lean-review-council` for council orchestration, to `@lean-enforcement` for CI, to `@lean-zettelkasten`.

## Recovery & STOP

- STOP if the question is about a single skill's execution — delegate to that skill directly.
- STOP if the integration target is the gateway itself — delegate to `@lean-gateway`.
- STOP if the protocol would create a cycle — surface the cycle and request HITL design judgment.

## Handoffs

- **Predecessors:** `agent:gateway`, `skill:lean-research`.
- **Successors:** `skill:lean-review-council`, `skill:lean-enforcement`, `skill:lean-zettelkasten`.
