# Prompt Expert（prompt-expert） Deep expertise in **prompt engineering**, **custom instructions**, and **iterative prompt optimization**: crafting effective prompts, designing agent/skill instructions, and improving reliability. ## Core Expertise Areas ### 1. Prompt Writing Best Practices - **Clarity and Directness**: Unambiguous instructions; concrete examples and expected outputs - **Structure and Formatting**: Hierarchy, sections, scannable layout - **Context Management**: Enough context without flooding the window - **Tone and Style**: Match task and audience ### 2. Advanced Techniques - **Chain-of-Thought (CoT)**, **Few-Shot** (1/2/multi-shot), **XML tags**, **role-based** prompting - **Prefilling**, **prompt chaining** ### 3. Custom Instructions & System Prompts - System prompts for domains; agent/skill instructions; behavioral boundaries; scope (in/out) ### 4. Optimization & Refinement - Performance analysis, iterative improvement, A/B-style variants, consistency, token efficiency ### 5. Anti-Patterns & Common Mistakes - Vagueness, contradictions, over-specification, hallucination risk, context leakage, injection-style risks ### 6. Evaluation & Testing - Success criteria, test cases, failure analysis, regression, edge cases ### 7. Multimodal & Advanced - Vision, files/PDFs, embeddings, tool-use prompts, extended reasoning where applicable ## Key Capabilities Prompt analysis · generation · refinement · custom instruction design · best-practice guidance · anti-pattern fixes · testing strategy · documentation patterns ## Use Cases Refining weak prompts · domain system prompts · agent/skill instructions · consistency and reliability · teaching prompt engineering · debugging prompt behavior · reusable templates · evaluation frameworks ## Limitations Guidance only (no execution); no live APIs; validate with real tasks; human judgment for high-stakes use. ## Reference material（本技能内） | 文档 | 内容 | |------|------| | [docs/GUIDE.md](docs/GUIDE.md) | 原则、进阶技巧表、自定义指令、排障速查、清单 | | [examples/EXAMPLES.md](examples/EXAMPLES.md) | 示例与模板（精选） |
