Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install rails-37signals-coding-conventions

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 applies 56 rules ranked by impact: vanilla Rails without superfluous gems, REST controllers, rich models, concerns, custom authentication and Minitest tests. You get lean Rails code in the style of the Fizzy codebase and 37signals projects.
