n8n-expression-syntax

n8n-expression-syntax is a Workflow automation & no-code skill for AI agents, published by czlonkowski in the n8n-mcp repository on GitHub. Skillspace rates n8n-expression-syntax F (53/100) and it passed the safety scan; the rating is based on static analysis only.

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.
