SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing effective prompts and validating their quality across models is complex and error-prone. Cortex-prompt provides a structured workflow to create, version, and evaluate prompts to ensure consistent results across tasks and deployments.

Core Features & Use Cases

  • Versioned prompts: manage prompts with changelogs and version history.
  • Evaluation harness: run automated test cases and scoring to quantify prompt quality.
  • Environment-aware prompts: detect LLM stacks and adapt prompts for different runtimes.
  • Production-ready packages: generate ready-to-use prompt bundles for experiments and production.

Quick Start

Create a versioned prompt package under prompts/v1 with a system prompt, user template, config, and examples, then run the evaluation harness to compare versions.

FAQPage Schema
How do I manage prompt versioning and evaluate prompt quality for LLMs?

Prompt versioning manages prompts with changelogs and version history, while an evaluation harness runs automated test cases and scoring to quantify prompt quality. This ensures repeatable, measurable results across development and production deployments.

What is the best way to automate prompt testing across different LLM environments?

Automating prompt testing uses environment detection to identify LLM stacks and adapt prompts for different runtimes. It runs automated test cases and scoring within an evaluation harness to deliver repeatable prompt quality across environments.

How do I create production-ready prompt packages for experiments?

Creating production-ready prompt packages involves generating versioned prompt bundles containing system prompts, user templates, configs, and examples. These ready-to-use bundles support both experimental evaluation and direct production deployment.

Does environment-aware prompt engineering work with different model runtimes?

Yes, environment-aware prompt engineering detects LLM stacks and adapts prompts for different runtimes. This environment detection ensures prompts remain compatible and maintain consistent performance across various development and production contexts.

Why do I need an evaluation harness for prompt engineering tasks?

An evaluation harness is needed to run automated test cases and scoring, quantifying prompt quality objectively. It validates prompt effectiveness across models before deployment, solving the error-prone nature of unstructured prompt validation.
