Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install slack-block-kit-layouts

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 establishes the target Slack surface, then composes blocks, elements and interactions to that surface's schema while keeping the existing payload contract. Plain text replies do not need blocks.
