Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install elixir-staff-level-practices

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 design decisions specific to Elixir: when a process is warranted, letting processes crash instead of rescuing, avoiding N+1 with Ecto and bounding concurrent tasks. It also covers LiveView rules and data access. You get simpler, sturdier code on the BEAM.
