How to Build a Prompt‑Optimizer Skill for Claude Using AI Coding Tools

Problem

Users often write prompts that are incomplete, ambiguous, or lack a suitable prompt framework. Existing prompt‑optimization tools tend to generate generic, overly‑structured prompts and support only a few large‑language models.

Solution – prompt-optimizer Skill

Selects the most appropriate professional prompt framework (over 50 top‑tier frameworks) based on the user’s described scenario.

Detects missing, ambiguous, or erroneous information and actively confirms with the user.

Automatically applies the chosen framework to generate an optimized prompt.

Allows the user to choose any preferred large‑language model.

Material Preparation

Collect a collection of professional prompt frameworks, for example from https://juuzt.ai/knowledge-base/prompt-frameworks/, and store them in a directory that will be added to the Claude skills repository.

Tool Packaging

Claude Skills

The skill follows Anthropic’s Skill specification. The official Anthropic Skills repository ( https://github.com/anthropics/skills) provides examples and the skill-creator utility for generating new skills.

/plugin marketplace add chujianyun/skills

/plugin install prompt-engineering-skills@chujianyun/skills

After installing the plugin, users can invoke the skill by name, provide their original prompt, and receive a clarified, framework‑based optimized prompt.

Chrome Extension

The skill can be packaged as a Chrome extension. The repository https://github.com/chujianyun/prompt-optimizer-extension contains the extension code, which reads the framework summaries, matches the best framework, clarifies user intent, and outputs the refined prompt.

Installation and Usage

Clone the skill repository: git clone https://github.com/chujianyun/skills Add the prompt-optimizer folder to the skills directory of the Claude Skills repo.

In Claude Code, install the skill:

/plugin install prompt-engineering-skills@chujianyun/skills

Describe the task and paste the original prompt. The skill will confirm ambiguities, select the appropriate framework, and return the optimized prompt.

Key Code Snippets (Skill Specification)

我希望你按照 Skill 规范，帮我把“提示词框架”这个文件夹改造成 “提示词优化专家”（需要改成英文）的 skill。当用户想要优化提示词时启用该功能。

流程：用户直接发送需求或者原始提示词，AI 需要从中选择最匹配的场景，然后匹配最适合的框架名称，读取对应的框架描述文件，判断用户的需求或原始提示词是否存在歧义或缺失，和用户进行核对，核对清楚以后，按照匹配的最佳提示词框架产出最终提示词。

Progressive Loading Considerations

When the number of prompt frameworks grows to dozens or hundreds, Claude’s progressive loading may require summarizing all available frameworks first, then using the summary to identify the most relevant framework before loading its full description.
