One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.
We have a Rust function returning Option<User> from an in-memory lookup. We need to convert a missing user into a custom AppError::NotFound variant and extract their age. Show how to chain this in Rust without manual match statements.
| Checked | Without skill | With skill |
|---|---|---|
| Uses ok_or_else to convert Option into Result with a lazy error closure | Missed | Passed |
| Chains map to transform the inner User struct into the age field | Passed | Passed |
The instructions your model reads when the skill loads.
Build resilient applications with robust error handling strategies that gracefully handle failures and provide excellent debugging experiences.
