Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langsmith-evaluation-datasets

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 picks the dataset type (final response, single step, trajectory, RAG), builds examples from exported traces or with the SDK, then uploads them to LangSmith. It then manages datasets and examples through the CLI. You get an evaluation dataset ready to use.
