    8: Prompting Techniques
    TECHNIQUEWHEN TO USE
    Be SpecificAlways. “Clean this CSV” → “Remove rows where column B is empty, dedupe on email”
    Give ExamplesWhen output format matters. Show 1-2 examples of what you want.
    Chain StepsComplex tasks. “First analyze, then summarize, then create action items”
    Set ConstraintsQuality control. “Max 500 words” or “Only use data from 2024”
    Assign RolesExpertise needed. “Act as a data analyst reviewing this dataset”
    Use /clear OftenBetween unrelated tasks to reset context

    Pro Pattern: Checkpoint + Iterate

    1. Ask Claude to make a plan first
    2. Review the plan before execution
    3. Let it create checkpoint
    4. Rewind (Esc twice) if something goes wrong
    5. Iterate with specific feedback
