Order human-run real-device app tests from your coding agent; verified bugs return as fix prompts.
AI SKILLS · Software engineering
Evaluate AI systems
Define representative tests and measure the errors that matter for a specific workflow.
Why this skill matters
A good demo does not establish reliability on unfamiliar inputs.
What to learn
- Build a representative test set
- Choose metrics for the cost of errors
- Compare versions against a baseline
Before you begin
Basic statistics and test design
PUT IT INTO PRACTICE
Build a work sample
Create a small labeled classification dataset. Compare two approaches and explain false positives and false negatives.
Evidence of progress
An evaluation report showing failure examples and a justified acceptance threshold.
