Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install n8n-expression-syntax-check

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes or fixes n8n expressions in double curly braces, reading data from the current node, other nodes, environment variables and webhook payloads. You get valid expressions and an explanation of the syntax errors.
