Install with the CLI

In a terminal, from the folder you want:

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

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 applies 46 rules ranked by impact: metadata, descriptions that trigger the right skill, progressive disclosure and trigger testing. You get more reliable skills and clearer MCP tool descriptions.
