Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install elixir-phoenix-antipatterns

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 reviews your Elixir or Phoenix code and flags the catalog's anti-patterns: errors as exceptions instead of values, business logic in LiveViews, N+1 queries with Ecto. It proposes the corrected version of each case.
