Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install n8n-expression-data-references

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 checks your expressions, replaces fragile $json references with named references to the source node and formats dates with Luxon. You get parameters that stay correct when the workflow changes.
