## When to Use This Skill

Choose and order examples covering edge cases so the model generalizes instead of copying surface patterns.
Use it whenever a matching task appears in conversation — the agent loads these instructions on demand.

## Steps

1. Cover each output field's edge cases once: empty, unicode, long input, ambiguity
2. Order examples easy-to-hard so difficulty ramps within context
3. Match example format byte-for-byte to the required output format
4. Prefer real production samples over invented ones
5. Rotate in failure cases you fixed, turning regressions into teachers
6. Measure: remove one example at a time, drop any whose removal costs nothing
7. Include one deliberately ambiguous item with the correct tie-break label
8. Balance classes in examples; imbalance biases predictions

## Common Pitfalls

- Six near-identical easy examples teaching style but not judgment
- Whitespace mismatches between examples and instructions
