n8n-skills is a collection of Claude Code skills and hooks that guide AI assistants in creating, validating, and deploying n8n workflows through the n8n-mcp server. Developers use it to automate workflow construction, configure nodes and expressions, resolve validation errors, and operate self-hosted n8n. The catalogue entries are its skills, hooks, plugins, and instruction.

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 | $0.02904 | $0.02904 |
| Opus 5.5 | $0.01162 | $0.01162 |
| Sonnet 5.5 | $0.00581 | $0.00581 |
| Haiku 4.5 | $0.00290 | $0.00290 |
Grade A, and why
n8n-skills CLAUDE.md scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
This is the n8n-skills repository - a collection of Claude Code skills designed to teach AI assistants how to build flawless n8n workflows using the n8n-mcp MCP server.
Repository: https://github.com/czlonkowski/n8n-skills
Purpose: 14 complementary skills that provide expert guidance on using n8n-mcp MCP tools effectively for building n8n workflows, plus deploying the self-hosted n8n that runs them.
Architecture:
- n8n-mcp MCP Server: Provides data access (800+ nodes, validation, templates, workflow management)
- Claude Skills: Provides expert guidance on HOW to use MCP tools
- Together: Expert workflow builder with progressive disclosure

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.
