n8n 표현식 문법을 검증하고 일반적인 오류를 수정합니다. n8n 표현식 작성, {{}} 문법 사용, $json/$node 변수 접근, 표현식 오류 문제 해결, 노드 간 데이터 매핑, 또는 워크플로에서 웹훅 데이터 참조 시 사용하세요.
이 스킬은 n8n 노드 간 데이터를 전달하는 핵심 메커니즘인 표현식 문법을 검증하고 오류를 수정하는 데 특화되어 있습니다. n8n 워크플로에서 가장 흔한 오류 원인은 잘못된 표현식 문법이며, 이 스킬은 {{}} 구문, $json, $node 변수 접근, 복잡한 표현식의 성능 영향 평가 등을 다룹니다. Claude Code, Cursor, Codex 등 주요 AI 에이전트 플랫폼에서 사용할 수 있으며, 사용자가 n8n 표현식 문제를 겪거나 이전 노드 데이터를 참조해야 할 때 자동으로 활성화됩니다. SKILL.md 문서를 기반으로 하여 실제 표현식 예제와 함께 구체적인 수정 방법을 제시하며, 표현식이 워크플로 성능에 미치는 영향에 대한 질문에도 답변할 수 있습니다.

n8n 표현식 문법을 검증하고 일반적인 오류를 수정합니다. n8n 표현식 작성, {{}} 문법 사용, $json/$node 변수 접근, 표현식 오류 문제 해결, 노드 간 데이터 매핑, 또는 워크플로에서 웹훅 데이터 참조 시 사용하세요. 이전 노드의 데이터를 참조하는 노드 필드를 구성할 때마다 이 스킬을 사용하세요. 표현식은 n8n이 노드 간 데이터를 전달하는 방식이며, 문법 오류는 워크플로 오류의 가장 흔한 원인입니다. 또한 복잡한 표현식이 성능에 영향을 미치는지 묻는 경우에도 사용하세요.
This repo contains 6 individual skills — each has its own dedicated page.
Write JavaScript code in n8n Code nodes. Use when writing JavaScript in n8n, using $input/$json/$node syntax, making HTTP requests with this.helpers / the $helpers global, working with dates using DateTime, troubleshooting Code node errors, choosing between Code node modes, or doing any custom data transformation in n8n. Always use this skill when a workflow needs a Code node — whether for data aggregation, filtering, API calls, format conversion, batch processing logic, or any custom JavaScript. Covers SplitInBatches loop patterns, cross-iteration data, pairedItem, and real-world production patterns. Also use when asked why a Code node or workflow is slow, which execution mode is faster, or how to cut per-item overhead on large datasets. EXCEPTION — for the AI-agent-callable Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode, a tool attached to an AI Agent), use the n8n-code-tool skill instead; it has a different runtime contract.
Write Python code in n8n Code nodes. Use when writing Python in n8n, using _input/_json/_node syntax, working with standard library, or need to understand Python limitations in n8n Code nodes. Use this skill when the user specifically requests Python for an n8n Code node. Note — JavaScript is recommended for 95% of use cases — only use Python when the user explicitly prefers it or the task requires Python-specific standard library capabilities (regex, hashlib, statistics). EXCEPTION — for Python in the AI-agent-callable Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode), use the n8n-code-tool skill instead (input is _query, return must be a string).
Expert guide for using n8n-mcp MCP tools effectively. Use when searching for nodes, validating configurations, accessing templates, managing workflows, managing credentials, auditing instance security, or using any n8n-mcp tool. Provides tool selection guidance, parameter formats, and common patterns. IMPORTANT — Always consult this skill before calling any n8n-mcp tool — it prevents common mistakes like wrong nodeType formats, incorrect parameter structures, and inefficient tool usage. If the user mentions n8n, workflows, nodes, or automation and you have n8n MCP tools available, use this skill first.
Operation-aware node configuration guidance. Use when configuring nodes, understanding property dependencies, determining required fields, choosing between get_node detail levels, or learning common configuration patterns by node type. Always use this skill when setting up node parameters — it explains which fields are required for each operation, how displayOptions control field visibility, and when to use patchNodeField for surgical edits vs full node updates.
Interpret validation errors and guide fixing them. Use when encountering validation errors, validation warnings, false positives, operator structure issues, or need help understanding validation results. Also use when asking about validation profiles, error types, the validation loop process, or auto-fix capabilities. Consult this skill whenever a validate_node or validate_workflow call returns errors or warnings — it knows which warnings are false positives and which errors need real fixes.
Proven workflow architectural patterns from real n8n workflows. Use when building new workflows, designing workflow structure, choosing workflow patterns, planning workflow architecture, or asking about webhook processing, HTTP API integration, database operations, AI agent workflows, batch processing, or scheduled tasks. Always consult this skill when the user asks to create, build, or design an n8n workflow, automate a process, or connect services — even if they don't explicitly mention 'patterns'. Covers webhook, API, database, AI, batch processing, and scheduled automation architectures. Also use when optimizing a slow workflow or speeding up large-item-count processing (node count, batchSize, all-items vs per-item).
Gemini CLI one-shot prompts, summaries, generation, skills, hooks, MCP, or Gemma routing.
Fetch GitHub issues, select candidates, spawn background fix agents, open PRs, and optionally process PR review comments.
Create, edit, audit, tidy, validate, or restructure AgentSkills and SKILL.md files.
Search, install, update, sync, or publish agent skills with the ClawHub CLI and registry.
Delegate coding work to Codex, Claude Code, or OpenCode as background workers; not simple edits or read-only code lookup.
List, configure, authenticate, call, and inspect MCP servers/tools with mcporter over HTTP or stdio.
