N8n

Use when the user wants to build, debug, or extend an n8n workflow - generating workflow JSON from a description, scaffolding a custom TypeScript node, building an AI agent (LangChain cluster), iterating over items, writing Code-node JS, linting an existing workflow, diagnosing a failed execution, or driving a live n8n instance via REST.

# n8n

Pairs with the `@automatelab/n8n-mcp` server. The server exposes 9 MCP tools; this skill tells you when to use which and where to load deeper context.

## Tool routing

Tool names use dot-notation: `node.*`, `workflow.*`, `execution.*` (renamed in v0.4.0 from `n8n_*`).

**Stateless tools** (work without any n8n instance):

- `workflow_generate` - plain-English description → workflow JSON. Detects AI-agent intent and emits a LangChain cluster.
- `node_scaffold` - description → single `INodeType` TypeScript file for a custom n8n package.
- `workflow_lint` - workflow JSON → list of issues (deprecated types, missing `typeVersion`, broken connections, AI Agent without `ai_languageModel`, IF v1 schema, etc.).
- `execution_explain` - failed/surprising execution JSON → diagnosis. Catches the #1 n8n pain point: items "silently disappearing" between nodes. Also flags unresolved `={{ ... }}` expressions and surfaces LLM token usage.

**Live-instance tools** (require `N8N_API_URL` + `N8N_API_KEY` env vars):

- `workflow_list` - paginate workflows; filter by active/tags/name.
- `workflow_get` - fetch a workflow by id. Pair with `workflow_lint` to audit deployed workflows.
- `workflow_create` - POST a generated workflow. Strips read-only fields. Workflow is created inactive.
- `workflow_activate` - flip active on/off.
- `execution_list` - browse executions; pass `includeData: true` for the full body. Pair with `execution_explain`.

Orca Orchestration Dev

nergury74/orca-orchestration-dev

Orca ADE의 오케스트레이션(멀티 에이전트 감독)으로 웹앱·앱 기능을 개발하는 워크플로우 스킬. 환경 조사 → 계약 확정 → Task DAG 설계 → 병렬 구현 → 통합 → 점검 순서로 진행하며, 파일 소유권 배정·결정 게이트·독립 검증 절차를 강제한다. "오케스트레이션으로 개발", "오케스트레이션으로 만들어줘", "Orca로 병렬 개발", "멀티 에이전트로 구현", "여러 에이전트에 나눠서 개발", "워커 나눠서 구현", "PRD로 Task 쪼개서 개발" 같은 요청이 있으면 반드시 이 스킬을 사용한다. 사용자가 PRD·기획서를 주면서 구현을 맡기거나, 여러 작업을 동시에 진행하며 감독·완료 추적을 원한다고 말할 때도 이 스킬을 쓴다. Orca 오케스트레이션 명령을 실행하기 전에는 항상 이 스킬을 먼저 읽을 것.
