Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install codemod-authoring-patternsWith 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 loginThe agent follows the codemod workflow: it generates the scaffold, creates fixtures, writes a failing test, then implements and verifies the transformation. It favors a minimal number of AST traversals and reuses the shared utilities in the lib folder, such as tracking class instances or renaming methods.
