n8n-Workflow-Patterns (czlonkowski)

Bewährte Workflow-Architekturmuster aus echten n8n-Workflows. Hilft beim Entwurf, der Optimierung und der Automatisierung mit n8n.

Was ist n8n-Workflow-Patterns (czlonkowski)?

Diese Skill-Sammlung enthält erprobte Architekturmuster für n8n-Workflows, die auf realen Implementierungen basieren. Sie deckt die wichtigsten Workflow-Kategorien ab: Webhook-Verarbeitung (mit Validierung, Fehlerbehandlung, asynchroner Verarbeitung), HTTP-API-Integration (Paginierung, Ratenbegrenzung, Authentifizierung, Fehlerwiederholungen), Datenbankoperationen (CRUD, Transaktionen, Batch-Inserts), KI-Agent-Workflows (Integration von LLMs, Memory, Tool-Use), Batch-Prozessierung (Chunking, Progress-Tracking, parallele Verarbeitung mit SplitInBatches) und geplante Aufgaben (Cron, Zeitfenster, Statusmanagement). Die Muster sind besonders nützlich beim Erstellen neuer Workflows, beim Optimieren langsamer Workflows (z.B. durch Anpassen von batchSize, NodeCount oder Wechsel von 'alle Items' zu 'pro Item'-Verarbeitung) und bei der Fehlersuche in bestehenden Automatisierungen. Jedes Muster ist als konkrete n8n-Knotenkonfiguration dokumentiert, mit Erwägungen zu Skalierbarkeit, Fehlerresistenz und Wartbarkeit. Die Sammlung unterstützt alle gängigen n8n-Plattformen (selbst gehostet, n8n Cloud, Docker) und setzt grundlegende n8n-Kenntnisse voraus.

Was macht n8n-Workflow-Patterns (czlonkowski)?

Bewährte Workflow-Architekturmuster aus echten n8n-Workflows. Verwende diese Muster beim Erstellen neuer Workflows, beim Entwerfen der Workflow-Struktur, bei der Auswahl von Workflow-Mustern, bei der Planung der Workflow-Architektur oder bei Fragen zur Webhook-Verarbeitung, HTTP-API-Integration, Datenbankoperationen, KI-Agent-Workflows, Batch-Verarbeitung oder geplanten Aufgaben. Konsultiere diese Fähigkeit immer, wenn der Benutzer darum bittet, einen n8n-Workflow zu erstellen, aufzubauen oder zu entwerfen, einen Prozess zu automatisieren oder Dienste zu verbinden – auch wenn er nicht explizit „Muster“ erwähnt. Deckt Webhook-, API-, Datenbank-, KI-, Batch-Verarbeitungs- und geplante Automatisierungsarchitekturen ab. Verwende sie auch, wenn du einen langsamen Workflow optimieren oder die Verarbeitung großer Elementanzahlen beschleunigen möchtest (Knotenanzahl, batchSize, alle Elemente vs. pro Element).

Individual skills in this repo

This repo contains 6 individual skills — each has its own dedicated page.

czlonkowski/n8n-code-javascript

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.

czlonkowski/n8n-code-python

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).

czlonkowski/n8n-expression-syntax

Validate n8n expression syntax and fix common errors. Use when writing n8n expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors, mapping data between nodes, or referencing webhook data in workflows. Use this skill whenever configuring node fields that reference data from previous nodes — expressions are how n8n passes data between nodes, and getting the syntax wrong is the most common source of workflow errors. Also use when asked whether a complex expression hurts performance.

czlonkowski/n8n-mcp-tools-expert

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.

czlonkowski/n8n-node-configuration

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.

czlonkowski/n8n-validation-expert

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.
