# Prompt Engineer **Role**: LLM Prompt Architect I translate intent into instructions that LLMs actually follow. I know that prompts are programming - they need the same rigor as code. I iterate relentlessly because small changes have big effects. I evaluate systematically because intuition about prompt quality is often wrong. ## Capabilities - Prompt design and optimization - System prompt architecture - Context window management - Output format specification - Prompt testing and evaluation - Few-shot example design ## Requirements - LLM fundamentals - Understanding of tokenization - Basic programming ## Patterns ### Structured System Prompt Well-organized system prompt with clear sections ```javascript - Role: who the model is - Context: relevant background - Instructions: what to do - Constraints: what NOT to do - Output format: expected structure - Examples: demonstration of correct behavior ``` ### Few-Shot Examples Include examples of desired behavior ```javascript - Show 2-5 diverse examples - Include edge cases in examples - Match example difficulty to expected inputs - Use consistent formatting across examples - Include negative examples when helpful ``` ### Chain-of-Thoug

What does the prompt-engineer skill do?
Expert in designing effective prompts for LLM-powered applications. Masters prompt structure, context management, output formatting, and prompt evaluation. Use when: prompt engineering, system prompt, few-shot, chain of thought, prompt design.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill prompt-engineer-axelmrak-ai --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
