n8n-claude-skills

Production-grade Claude Skills for building, debugging, and shipping n8n workflows — distilled from 100+ production workflows by an n8n Verified Creator.

Give Claude Code the instincts of a senior n8n engineer. No more hallucinated node types, broken expressions, or toy demos.

# 60-second install
npx n8n-claude-skills install

Then in Claude Code:

"Build me an n8n workflow that ingests leads from a webhook, enriches them via SerpAPI → Apollo waterfall, scores spam with a composite check, and writes qualified leads to Google Sheets."

Claude now builds a real, production-shaped workflow — correct node types, proper expressions, checkpoint tables, error branches, and retry logic. Not a Figma mockup of a workflow. A workflow.

What's in the box

Skill	What it does	When it fires
workflow-architect	Designs n8n workflows from requirements. Picks the right nodes, structures branches, and wires error paths.	"build a workflow that…", "design an automation for…"
chain-llm-pattern	The Groq/OpenAI chain_llm pattern for multi-step LLM reasoning (entity extraction → categorization → scoring).	"extract structured data with LLMs", "multi-step prompt chain"
enrichment-waterfall	Multi-vendor enrichment waterfalls (SerpAPI → Hunter → Apollo → LLM fallback) with cost-aware fallbacks.	"lead enrichment", "data waterfall", "Clay alternative"
mysql-checkpointing	Production MySQL patterns: batch processing, duplicate prevention, resumable pipelines, dynamic table creation.	"idempotent pipeline", "checkpoint table", "batch processing"
debug-workflow	Systematic n8n debugging: expression syntax, pinned data, sub-workflow isolation, execution log reading.	"why is my workflow failing", "debug this n8n error"

More shipping weekly. PRs welcome.

Why this exists

LLMs confidently hallucinate n8n. They invent node types (Googlesheets instead of Google Sheets), mix up expression syntax ({{$json["x"]}} vs ={{ $json.x }}), forget about sub-workflows, and ship demos that collapse the moment you plug in real data.

This pack teaches Claude the patterns that actually survive production — the ones we use in:

• Real estate financial reporting (Google Sheets → Claude API → PDF → Gmail)
• Multi-language call transcript pipelines (EN/ES/PT, Groq chain_llm)
• Composite spam scoring with Twilio retry logic
• 47-node batch processing with duplicate prevention
• WhatsApp commerce agents with Stripe + Meta Cloud API

You get the instincts, not the code.

Install

Claude Code (recommended)

# Clone and install to your user skills directory
git clone https://github.com/masteranime/n8n-claude-skills.git
cd n8n-claude-skills
./install.sh

Claude Code picks up the skills automatically.

Manual (any Skills-compatible agent)

Copy any folder inside skills/ into your agent's skills directory. Each folder is a self-contained skill with a SKILL.md and optional reference files.

Works with: Claude Code, Cursor, Codex, Gemini CLI, Opencode, and anything following the Agent Skills spec.

Quick demo

Prompt:

Build an n8n workflow that receives Stripe checkout.session.completed webhooks, looks up the customer in our MySQL orders table, sends a WhatsApp confirmation via Meta Cloud API, and retries via Twilio SMS if WhatsApp fails.

Without this pack: Claude writes pseudocode, invents Whatsapp Node, forgets the retry branch, skips the idempotency check.

With this pack: Claude produces a 14-node workflow JSON you can paste into n8n — with webhook signature verification, a MySQL processed_webhooks checkpoint, proper Meta Cloud API messages endpoint, an IF branch on WhatsApp failure feeding into Twilio with exponential backoff, and an error trigger sub-workflow.

Full example: examples/stripe-whatsapp-fallback.json

Muhammad Shaheer — n8n Verified Creator (100+ workflows), Claude Code daily user, 4+ years shipping production AI automation.

These skills are extracted from real client work — real estate finance pipelines, multi-language NLP, voice lead automation, lead enrichment waterfalls. If a pattern is in here, it shipped to a paying customer first.
