Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install openai-to-anthropic-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 maps OpenAI and Anthropic endpoints, swaps the SDK with before and after code, then flags the key differences: required max_tokens, system as a top-level parameter, alternating messages, response path and streaming events. You get a migration located file by file.
