Prompt Engineering

Comprehensive prompt engineering guidance covering Claude (Anthropic), Gemini (Google), and Grok (xAI). Each model has unique strengths and optimal prompting patterns.

When to Invoke This Skill

Use this skill when:

  • Crafting prompts for Claude, Gemini, or Grok models
  • Leveraging model-specific capabilities (XML tags, system instructions, real-time knowledge)
  • Working with long-context tasks (up to 1M+ tokens)
  • Implementing extended thinking or reasoning features
  • Building agentic workflows with parallel tool use
  • Designing prompts for multimodal inputs (text, images, audio, video)
