SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the inconsistency and unpredictability of LLM outputs by providing a systematic framework for prompt design, testing, and failure diagnosis.

Core Features & Use Cases

  • Instruction Design: Standardizes the creation of roles, constraints, and output contracts to ensure reliable model behavior.
  • Systematic Evaluation: Provides a methodology for measuring prompt performance against a set of real-world inputs to prevent regressions.
  • Use Case: When a customer support classifier is miscategorizing 15% of technical tickets, this skill guides you through testing hypotheses, refining boundary examples, and verifying accuracy improvements.

Quick Start

Use the prompt-engineering skill to evaluate my current support ticket classifier against a set of 40 test cases and identify why it is misclassifying technical messages.

FAQPage Schema
How do I stop my LLM from misclassifying support tickets?

To fix LLM misclassification, evaluate your prompt against a defined set of test cases to systematically measure accuracy, diagnose failure points, and iteratively refine instructions. This structured evaluation prevents regressions by verifying improvements on real-world inputs.

What is the best way to evaluate prompt quality for production features?

The best way to evaluate prompt quality is to measure performance against a defined evaluation set of inputs and expected outputs. This systematic testing methodology isolates failure points, tests hypotheses, and verifies accuracy improvements before deploying to production.

Can I use chain-of-thought prompting to improve model reliability?

Yes, chain-of-thought prompting is a technique applied within the instruction design phase to standardize roles, constraints, and output contracts. This systematic framework ensures reliable model behavior by structuring the reasoning process.

Why does my prompt stop working after migrating to a new LLM?

Prompts often fail after model migration due to differences in how new LLMs interpret instructions and constraints. A systematic evaluation framework measures prompt performance against your existing test cases to diagnose failures and iterate on prompt design for the new model.

Do I need few-shot examples to get consistent LLM outputs?

While few-shot examples help guide behavior, consistent LLM outputs require standardizing instruction design with clear roles, constraints, and output contracts. A structured framework tests whether your few-shot prompts actually improve accuracy across your evaluation set.
