Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install migrate-deep-agents-to-harness

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 first establishes the source contract and checks the origin of the deepagents import, then builds the target from Pydantic AI primitives and Harness capabilities. It migrates and verifies each observed contract. You get an application that keeps its behaviour without copying the shape of create_deep_agent.
