    Search for specific patterns

    Search for keywords like 'structured', 'expert', 'technical' to find prompts that match your communication style. Look for prompts with high quality examples and clear output formats.

  3. 3

    Adapt for your context

    Copy a prompt and modify the instructions to fit your specific project. Change example outputs, add domain-specific terminology, and specify output format (JSON, markdown, plain text) that your pipeline expects.

  4. 4

    Test and iterate

    Run the adapted prompt against your actual use case (code snippets, documents, etc.). Compare outputs from different prompt variations to find the one that produces the most useful results.
