Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install claude-prompt-writing-improvement

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 the techniques Anthropic recommends: clear instructions, XML tags, step-by-step reasoning, prefilling and examples. You get a structured prompt and a list of common mistakes avoided.
