SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The LLM app development skill provides a structured approach for building software that uses large language models as a core component: designing pipelines, evaluating prompts, and monitoring production features.

Core Features & Use Cases

  • Eval-driven development and prompt versioning to ensure reliable AI features
  • RAG and agent-tool patterns with safe execution models and monitoring
  • Production-grade LLM feature design, testing, and deployment gating

Quick Start

Define a new LLM feature by choosing a pattern, drafting prompts, and running the eval harness to validate it.

FAQPage Schema
How do I build reliable LLM features for production?

To build reliable LLM features for production, use an eval-driven development workflow combined with prompt versioning and risk management gates to validate behavior before deployment.

What is the best way to evaluate prompts for RAG pipelines?

Evaluating prompts for RAG pipelines requires running an eval harness to test pattern selection and drafted prompts, ensuring the retrieval and generation logic meets production-grade standards.

How does eval-driven development work for AI chatbots?

Eval-driven development for AI chatbots works by defining a feature pattern, drafting prompts, and executing an evaluation harness to validate outputs and gate deployment based on test results.

Do I need production monitoring for LLM orchestration?

Production monitoring for LLM orchestration is required to track agent tool patterns, ensure safe execution models, and maintain stability when integrating large language models into software products.

Can I use this approach to test agent tools with safe execution?

Yes, this approach supports testing agent tools with safe execution models by providing structured guidance for designing, evaluating, and monitoring production-grade LLM features.

When should I implement prompt versioning in LLM applications?

Prompt versioning should be implemented during LLM application design to track iterations, maintain reliability across features, and satisfy production deployment gating requirements.
