    Example session with this skill installed

    Audit my customer support agent's prompt. It failing to extract JSON from long transcripts, and I need a fix that improves the parse rate without breaking the classification accuracy.

    AUDIT FINDING: Brittle JSON Extraction
    ROOT CAUSE: Input nesting exceeding 3 levels causing token attention drift.
    REWRITE: Moved extraction policy to system header; simplified schema.
    EVAL: Re-run of 50 tests shows 100% parse rate (up from 72%). No regressions in classification accuracy.

    About this skill

    What it does

    Prompt Engineer Pro is a production-grade system for teams shipping AI workflows into business-critical environments. Unlike basic prompting assistants, this skill treats prompts as software assets that require governance, audit trails, and regression testing. It helps you build, audit, and harden prompt stacks for complex tasks involving multiple models, tool-use agents, and structured data extraction.

    Why use this skill

    Engineering prompts for production requires more than just "good phrasing." This skill provides a structured framework for handling provider migrations (e.g., GPT-4 to Claude 3.5), hardening JSON/XML output contracts, and designing tool-call policies that prevent agent hallucinations. It moves your workflow from "trial and error" to an evidence-based evaluation harness.

    Key Capabilities

    • Prompt Audits: Identifies root-cause failures in existing prompt stacks and provides prioritized fixes.
    • Structured-Output Hardening: Ensures prompts reliably feed downstream APIs and automation.
    • Provider Migration: Manages the transition between model families without silent regressions.
    • Tool-Call Policy Design: Establishes clear decision rules and safety boundaries for agentic actions.
    • Evaluation & Triage: Sets up regression gates and release conditions to ensure launch readiness.

    The output is not just a rewritten prompt; it is a professional audit memo, a prioritized failure taxonomy, and a verified test plan designed for engineering teams.
