What it does

Validate n8n expression syntax and fix common errors.

Use when writing n8n expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors, or working with webhook data in workflows.

How it arrives

You don't install skills one by one. ClevskillSetup installs the whole curated pack, wires the safety hooks, and verifies each skill actually runs on your machine. The weekly health scan re-checks it from then on, and repairs route through your approval.

Setup

No setup needed. It works as soon as the pack is installed; no accounts, no API keys, nothing leaves your machine.

Invoke it

In Claude Code or Claude Cowork, just ask in plain language; skills trigger on intent. Things people say that make this skill run:

you: use n8n expression syntax on this
claude: [n8n-expression-syntax runs, result returned with full audit log]

A developer tool: guardrails and helpers that make AI-assisted coding safer and faster.
