Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-skill-authoring-3

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 clarifies the capability, triggers and required knowledge, then chooses between a single-file skill and a skill with references. It writes the SKILL.md, checks the frontmatter and file layout, and tests the skill with the wording users are likely to use. You get a skill ready to use.
