"""
Evaluate Skill Output -- LayerLens + OpenClaw
==============================================
Evaluates the output quality of an OpenClaw skill by running a set of
test prompts, uploading each execution as a LayerLens trace, and scoring
with safety, accuracy, and helpfulness judges.

Workflow:
  1. Define test prompts that exercise a specific skill.
  2. Execute each prompt via OpenClaw.
  3. Upload each execution as a trace.
  4. Evaluate all traces with three judges.
  5. Print a quality report with pass rates per judge.

Prerequisites:
    pip install layerlens --index-url https://sdk.layerlens.ai/package openclaw
    export LAYERLENS_STRATIX_API_KEY=your-api-key

Usage:
    python evaluate_skill_output.py
