 ===== How It Works ===== ===== How It Works =====
  
-Promptfoo uses a declarative configuration approach. You define **providers** (LLM endpoints), **prompts** (templates with variables), and **tests** (input/output assertions) in a YAML config file. The tool runs each prompt through each provider with all test cases, applies assertions to score outputs pass/fail, and generates comparison reports.+Promptfoo uses a declarative configuration approach.
