A reference for building n8n v2.0 workflows, which are automated sequences connecting apps and services. It covers workflow JSON, approval waits, API credentials, expressions, and common workflow patterns.

Use it to create, import, troubleshoot, and improve n8n workflows, including approval steps, sub-workflows, API connections, and JavaScript-based file handling.

It helps avoid unsupported n8n nodes and common setup or workflow errors. It also explains how to handle file operations when the default n8n container lacks the Execute Command node.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.01279
Opus 5	$0.00031	$0.00639
Sonnet 5	$0.00012	$0.00256
Haiku 4.5	$0.00006	$0.00128

Security

Grade A, and why

claude scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

n8n v2.0 Workflow Development (Claude Code)

This is the Claude Code-specific version of the n8n-v2-workflow skill. References point to the shared references/ and ../code-snippets/ directories in the parent skill folder.

Critical: No Execute Command Node

The n8n-nodes-base.executeCommand node is NOT available in the default n8n container image. Do NOT use it in any workflow.

Instead, use Code nodes (JavaScript) with the Node.js fs module for all file operations:

fs.readdirSync() instead of find / ls
fs.readFileSync() instead of cat
fs.writeFileSync() instead of echo >
fs.renameSync() instead of mv
fs.existsSync() instead of test -f

Overview

Comprehensive reference for building n8n workflows using v2.0 patterns and best practices. This skill provides complete documentation for nodes, expressions, patterns, troubleshooting, and production-ready examples.

Quick Start Guide

1. Test APIs First

curl -X GET "https://api.example.com/endpoint" \
  -H "Authorization: Bearer $TOKEN"

2. Create Workflow JSON

Generate workflow JSON with nodes and connections.

3. Import into n8n

n8n UI > Settings > Import from File

4. Configure & Fix

Replace Execute Sub-Workflow nodes (if needed)
Configure credentials
Test each node

5. Test Execution

Use MCP server mcp__n8n__execute_workflow or manual trigger

Core Concepts

n8n MCP Server Integration

What it CAN do:

✅ Search workflows
✅ View workflow details
✅ Execute workflows

What it CANNOT do:

❌ Create workflows
❌ Modify workflows
❌ Manage credentials

Workaround: Generate JSON files, import via UI

Node Library

Complete reference for all n8n nodes:

Trigger Nodes: Manual Trigger, Execute Workflow Trigger Data Processing: Code, Set, Merge, Filter, Split in Batches Flow Control: IF, Wait Integration: HTTP Request, RSS Feed Read Action: Execute Workflow, Respond to Webhook

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claude is a skill published in the GitHub repository S3YED/appie-kit (7 stars, last pushed 10d ago), licensed MIT. It adds 62 tokens to every session and 1,279 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
