Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install claude-agent-sdk-to-pydantic-ai

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 identifies the real entry point (query() or ClaudeSDKClient), chooses the smallest Pydantic AI target, then migrates one vertical slice with prompts, tools, sessions and approvals. It does not cover the plain Messages API or managed agents. You get a migration verified against your callers' behaviour.
