Our review

Expert prompt engineering skill for crafting effective prompts for LLM coding agents across multiple tools, producing strategy documents and ready-to-use prompt artifacts.

Strengths

  • Adapts prompts to target tool conventions (Claude Code, Cursor, Codex, etc.)
  • Uses proven techniques from prompting research
  • Provides strategy documents and ready-to-use artifacts
  • Can iterate and refine using reference docs

Limitations

  • May require understanding of specific tool context
  • Effectiveness depends on clarity of user intent
  • Might not cover tool-specific quirks outside documented conventions
When to use it

Use when you need to create highly effective prompts for coding agents, especially when adapting to different tool interfaces or complex tasks.

When not to use it

Avoid when simple direct prompts suffice, or when the tool's built-in prompt patterns are adequate.

Security analysis

Safe
Quality score80/100

The skill only provides meta-level guidance on writing prompts for AI coding tools. It uses read-only and search tools (Read, Glob, Grep, WebFetch, WebSearch) and has no ability to execute commands or modify system state.

Examples

Cursor Prompt for Feature Implementation
Create an expert prompt for Cursor to implement a user authentication system using JWT. The prompt should follow Cursor's conventions and include step-by-step instructions, error handling, and testing guidelines.
Claude Code Strategy Document
Write a strategy document and ready-to-use prompt for Claude Code to refactor a legacy Python module. Include research-based prompting techniques and ensure the prompt is tailored to Claude Code's capabilities.
Multi-Tool Prompt Adaptation
I need a prompt that works for both Claude Code and Codex to generate unit tests for an API. Adapt the prompt to each tool's conventions and provide two versions.
