# czlonkowski/n8n-skills: Claude Code Skills for Building n8n Workflows

> A set of 14 Claude Code skills plus a router and hooks layer that teaches Claude to build n8n workflows through the n8n-mcp server. It is a prompt-and-convention pack, not a workflow engine, and it only pays off if you already run n8n-mcp.

## The problem: n8n workflows are easy to describe and hard to build correctly

n8n is a workflow automation tool, and the repository assumes you already know that. The skills exist because building n8n workflows programmatically goes wrong in repeatable ways. The README lists the failures it targets: using MCP tools incorrectly or inefficiently, getting stuck in validation error loops, not knowing which workflow patterns to use, and misconfiguring nodes and their dependencies. Each of those is a different kind of mistake, and each has its own skill.

The audience is narrow and specific. You need Claude Code, and you need the n8n-mcp MCP server, which lives in a separate repository by the same author. The skills are instructions and conventions for the assistant, not a runtime. Nothing here executes a workflow. If you are looking for a library that calls the n8n API from your own code, this is the wrong repository. The README also states that the author sells n8n automation audits and builds through AiAdvisors, which is worth knowing when you read the marketing around the project.

## How the skills are structured: a router, 14 specialists, and a hooks layer

The repository layout shows a skills/ directory, a hooks/ directory, a .claude-plugin/ directory, and an mcp.json alongside an .mcp.json.example. The README describes the contents as 14 complementary Claude Code skills plus an always-on router skill and a hooks enforcement layer. That router is the architectural centre: instead of loading every skill into context, an always-on skill decides which specialist applies and routes to it.

Each specialist is scoped to a trigger condition. The expression syntax skill activates when you write {{}} expressions or troubleshoot them. The MCP tools skill activates when you search for nodes or validate configurations. The validation skill activates when validation fails. The error handling skill activates when you build webhook or API workflows, wire error outputs, set retries, or chase silent failures. The README marks the MCP tools skill as the highest priority of the set.

Some skills carry distinctions that are easy to get wrong without them. The Code Tool skill separates the AI-agent-callable Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode) from the regular Code node: different node type, different return format, different sandbox. The Code node returns [{json: {...}}]; the Code Tool returns a string, with JSON.stringify() for structured output. The README also notes that $fromAI() does not work in the Code Tool, and that the sandbox there has no $input, $helpers, $json or $getWorkflowStaticData, and no state across calls. Those are the kinds of facts that are cheap to write down and expensive to rediscover.

## Installing the plugin and getting a first workflow out of it

The repository ships .claude-plugin/ and mcp.json, which is how a Claude Code plugin is packaged. The README does not print a step-by-step install command, so treat the plugin directory and the example MCP config as the entry points. Start by checking what the plugin manifest declares, then copy the example MCP configuration into place.

```bash
git clone https://github.com/czlonkowski/n8n-skills.git
cd n8n-skills
ls .claude-plugin/ mcp.json .mcp.json.example
```

The listing should show the plugin manifest, a committed mcp.json, and an example variant. The example file is the one to read first, because it shows the shape the MCP entry expects without committing anything.

```bash
cat .mcp.json.example
```

Once n8n-mcp is reachable through that configuration, a first real use is a validation pass rather than a build. Ask Claude to validate the node configuration you already have. The validation skill is designed for exactly that moment, and the MCP tools skill documents the validation profiles (minimal, runtime, ai-friendly, strict) so you can pick one deliberately instead of accepting whatever default the server applies.

```bash
# inside Claude Code, with the plugin loaded and n8n-mcp connected
# ask for node search first, then validate the configuration
```

The README does not document rollback, nor does it describe an uninstall path for the plugin. If you need to back out, you are editing Claude Code's plugin configuration by hand.

## Where the skills stop: sandbox limits, missing libraries, and no runtime

The Python skill states plainly that JavaScript should be used for 95% of use cases, and that Python Code nodes have no external libraries: no requests, no pandas, no numpy. That is a real constraint on the node, not on the skills, but the skill is honest about it and points to standard library workarounds instead of pretending the gap does not exist.

The JavaScript skill has a similar correction. It documents this.helpers.httpRequest() as the supported path and notes that the bare $helpers global is undefined in the task-runner sandbox, recommending the HTTP Request node for non-trivial or authenticated calls. If you have old n8n code using $helpers, the skill will steer you away from it.

The larger limitation is architectural. These skills shape what Claude writes; they do not verify it against a live n8n instance by themselves. Validation runs through n8n-mcp, so an unreachable or misconfigured MCP server turns the whole set into advice with no feedback loop. The README also flags false positives in the validation skill, which means a clean validation result is not proof the workflow is correct. If you do not use Claude Code, none of this applies to you at all.

## Compared with writing your own n8n prompt context

The obvious alternative is a hand-written system prompt or a project-level CLAUDE.md that you maintain yourself. The difference is upkeep. A personal prompt drifts: n8n changes node behaviour, and nobody tells you your prompt is stale. This repository versions its knowledge, and the release history shows it moving with the platform. v1.30.0 added queue-mode environment parity to the self-hosting skill, v1.31.0 added managed OAuth via credential overwrites, and v1.34.0 added official-MCP tools and routed workflow operations.

That cadence is the actual product. The last push was on 2026-09-03, so the repository is current, and the releases are dated within weeks of each other. The trade-off is that you inherit someone else's opinions about how n8n should be used, including a preference for JavaScript Code nodes and a specific set of five workflow patterns drawn, per the README, from 2,653+ n8n templates. If your team has settled on different conventions, a short internal prompt may fit better than a 14-skill pack you have to argue with.

## Licence, upgrade cost, and what maintenance actually means here

The licence is MIT, and the repository carries NOTICES and NOTICES-APACHE-2.0.txt at the top level. The Apache notice matters: it means some bundled or referenced material comes under Apache 2.0 terms, so if you redistribute the package, read those two files rather than assuming MIT covers every file. This is a description of what the files say, not legal advice.

Upgrade cost is low but not zero. The skills are Markdown and scripts, so pulling a new version is a git operation, but each release can change the conventions Claude follows. A team that has tuned its own prompts around the old behaviour will notice v1.34.0's routed workflow operations and official-MCP tools. Budget a re-read of the changelog per release rather than a silent pull.

Maintenance status is straightforward: the repository is not archived, and the most recent push recorded is 2026-09-03. That is recent enough to treat the project as live, and the release notes show feature work rather than typo fixes. What the repository does not show is a contributor base, a support channel, or a deprecation policy. The README documents the author's commercial services, which is the closest thing to a support path it offers.

## Conclusion

Adopt it if you already build n8n workflows through Claude Code and n8n-mcp, because the skills encode expression syntax, validation profiles and node configuration rules that are otherwise learned by trial and error. Do not adopt it if you expect it to author workflows without n8n-mcp installed, or if you are not a Claude Code user, since the package is a skill set for that client. Verify first that your Claude Code version loads plugin skills from .claude-plugin/ and that mcp.json points at a working n8n-mcp instance.

## FAQ

### What is n8n-skills?

It is a Claude Code plugin containing 14 skills, an always-on router skill and a hooks enforcement layer that teach Claude how to build n8n workflows through the n8n-mcp MCP server. The repository also covers deploying the self-hosted n8n that runs those workflows.

### What n8n skills does Claude have?

The README lists 14, including expression syntax, MCP tools, workflow patterns, validation, node configuration, JavaScript and Python Code nodes, the Custom Code Tool, error handling, and binary and data handling. An always-on router skill decides which one activates.

### How do n8n skills and MCP fit together?

The skills are instructions for the assistant; n8n-mcp is the separate MCP server that supplies node search, validation and workflow operations. The README states the skills teach Claude to build workflows using that server, so the skills depend on n8n-mcp rather than replacing it.

### Is n8n a good skill to learn?

The repository does not discuss n8n as a career skill. It assumes you already work with n8n and addresses a narrower problem: building workflows programmatically without falling into MCP misuse, validation loops and node misconfiguration.

### What are the prerequisites to learn n8n?

For this repository specifically, the prerequisites are Claude Code and a working n8n-mcp connection. The README does not state general n8n learning prerequisites, and the skills assume familiarity with nodes, expressions and workflow structure.

### What does n8n actually do?

The README treats n8n as the workflow automation platform the skills build for, covering webhook processing, HTTP API, database, AI and scheduled patterns. It does not give a general product description beyond that.
