Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install legacy-strangler-migration

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 assesses the existing system, maps its dependencies and risks, then sets up test coverage and integration contracts. You get a progressive replacement plan, component by component.
