Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install prompt-versioning-templates

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 gathers scattered prompts into a module, publishes them to the LangSmith hub and pulls them by commit hash in production. It proposes XML conventions for Claude, example selectors and extraction schemas. You get versioned prompts, a possible rollback and an A/B test ready to run.
