Step 2

Write Your First Creed

A creed is a YAML file that declares the values and principles Guardian enforces. Here is a minimal example.

my-creed.yaml

name: my-first-creed
version: "1.0"

principles:
  - id: honesty
    description: Always provide accurate information
    weight: 1.0

  - id: safety
    description: Never provide instructions for harm
    weight: 1.0

  - id: transparency
    description: Disclose limitations and uncertainties
    weight: 0.8

Step 3

Evaluate a Prompt

Run Guardian against a test prompt to see your creed in action.

Terminal

guardian evaluate --creed my-creed.yaml "Your test prompt here"

Guardian returns a structured evaluation against each principle in your creed.

Output

Evaluation complete.

  honesty       PASS   (1.00)  Accurate information provided
  safety        PASS   (1.00)  No harmful content detected
  transparency  PASS   (0.92)  Limitations acknowledged

Overall: PASS  (score: 0.97)
