    Example session with this skill installed

    My support-ticket triage prompt on GPT-4o-mini keeps tagging billing complaints as "technical" and sometimes answers in prose instead of JSON. The prompt is: "You are a helpful assistant. Read the ticket and categorize it. Categories: billing, technical, account, other. Be accurate." Please fix it.

    • Read your context and instructions
    • Compiled the prompt engineering specialist
    • Generated the UI component

    The prompt fails on three components: no category definitions, no output contract, and no examples for the billing/technical overlap.

    CategoriesLabels onlyDefinitions plus a tie-break

    ExamplesNoneTwo cases on the billing/technical boundary

    Rewritten prompt

    You classify support tickets. Reply with JSON only:
    {"category": "billing|technical|account|other", "reason": "<10 words max>"}
    
    billing: charges, refunds, invoices, plans, payment failures
    technical: product errors, bugs, outages, integrations
    account: login, password, profile, permissions
    other: anything else
    
    Tie-break: if money or a charge is mentioned, choose billing.
    
    Ticket: "I was charged twice after the app crashed at checkout."
    {"category": "billing", "reason": "duplicate charge"}
    
    Ticket: "Export to CSV throws error 500."
    {"category": "technical", "reason": "export error"}
    
    Ticket: {{ticket_text}}

    Next steps

    • Run R1 to R4 plus 20 real tickets before and after.
    • Turn on the API's JSON response format as a second guard.
    • Add each future misroute to the set.

    About this skill

    Production prompts grow by accretion — every failure gets another appended rule until the prompt is two thousand words of contradictions that the model navigates unpredictably. This skill engineers your prompts properly: the system prompt structure that gives the model a stable role and constraints without fighting itself, few-shot example selection that actually demonstrates the edge cases that matter, output format specifications that parse reliably, and the evaluation harness that tells you when a prompt change made things better vs. just different. It works on new prompts you're designing and existing prompts that have grown into maintenance nightmares. Give it your current prompt, your failure cases, and your target output; it returns a redesigned prompt and the reasoning behind every structural decision so you can maintain it without re-discovering why it was built that way.
