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.
