Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install twelve-factor-app-methodology

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 51 rules covering the whole lifecycle: one codebase, explicit dependencies, environment-based configuration, backing services, build, release, run and stateless processes. You get a portable application ready for containers and CI/CD.
