Minimal access
Why this level
- The skills only add knowledge to the agent, and changes to workflows come from n8n-mcp tools if the user connected them.
Install
- Works in
In your terminal, with SkillFoxx CLI
npx skillfoxx add skills/antigravity-n8n-skillsDetects the agents on your machine, shows the access level and pins the version.

What it does
antigravity-n8n-skills is a port of the n8n-skills set, built for Claude Code, to Google Antigravity. It holds 15 skills: 14 for workflow development and one always-on router. The agent learns correct expression syntax in `{{ }}`, how to choose n8n-mcp tools, common workflow patterns, how to read validation errors and how to configure nodes per operation. Separate skills cover JavaScript and Python in Code nodes, the Code Tool called by an agent, binary data handling, subworkflows, error and retry handling, multiple n8n instances and self-hosted deployment. Skills activate on their own when a request touches n8n, for example a question on reading a webhook body through `$json.body`.
Who it is for. People who build n8n automation with a Google Antigravity agent and want it to know nodes and expressions.
Good fit when
- The agent writes an expression for webhook data and must remember it lives in `$json.body`.
- Workflow validation fails and the error catalog and false positives must be sorted out.
- A Python Code node needs awareness of limits: external libraries such as `pandas` are absent.
- A self-hosted n8n server is deployed with several instances.
Not a fit when
- You work in Claude Code: the original n8n-skills set exists for it.
- You need n8n-mcp itself: the skills only teach how to use its tools.
- A license check is required: none is stated in the repository.
Example request
How do I read the incoming webhook body in an n8n expression and configure an HTTP Request node correctly?Limitations
The set targets Google Antigravity and goes into `~/.gemini/antigravity/skills` or the project's `.agent/skills`. For validation and template tools the agent needs a connected n8n-mcp, which the skills do not install. The repository has no license file, and the project is described as a port of someone else's work. The skills capture n8n practices at the time of writing and do not track node updates. The last commit in the repository was made in October 2026.
How to disable. Delete the skill folders from `~/.gemini/antigravity/skills` or the project's `.agent/skills` and restart Antigravity.
FAQ
How do I install the set globally?
Open `~/.gemini/antigravity/skills` and run `git clone https://github.com/WilkoMarketing/antigravity-n8n-skills.git .`. The skills become available in all conversations and workspaces.
How do I install it for one project only?
Create `.agent/skills` in the project root and clone the repository into that folder with `git clone https://github.com/WilkoMarketing/antigravity-n8n-skills.git .agent/skills`.
Do I have to invoke the skills manually?
No. They activate automatically when a question touches n8n, and the always-on router points the agent to the right skill.
What is the Code Tool in n8n?
It is a code node an AI agent calls. It must return a string, and input arrives in `query` or `_query`.
Where does the set come from?
It is a port of the n8n-skills project, built for Claude Code, to Google Antigravity.

README in short
The repository consists of 15 folders with `SKILL.md` and supporting files: agent patterns, binary data, JavaScript and Python code, error handling, subworkflows and self-hosting. A separate `using-n8n-mcp-skills` skill acts as the router.

name: n8n-expression-syntax
description: 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.

# n8n Expression Syntax
Expert guide for writing correct n8n expressions in workflows.
---
## Expression Format
All dynamic content in n8n uses **double curly braces**:
```
{{expression}}
```
**Examples**:
```
✅ {{$json.email}}
✅ {{$json.body.name}}
✅ {{$node["HTTP Request"].json.data}}
❌ $json.email (no braces - treated as literal text)
❌ {$json.email} (single braces - invalid)
```
---
## Core Variables
### $json - Current Node Output
Access data from the current node:
```javascript
{{$json.fieldName}}
{{$json['field with spaces']}}
{{$json.nested.property}}
{{$json.items[0].name}}
```
### $node - Reference Other Nodes
