# Failure And Anti-Pattern Library

This directory captures recurring ways a skill can fail before, during, or after packaging.

Use it for three things:

- regression design
- author training
- description and boundary tuning

Current case library:

- `one-off-vs-reusable`
- `explain-not-package`
- `document-export-vs-agent-skill`
- `future-outline-vs-build`

Each family now includes a `cases.json` file so the anti-pattern can run in automated regression instead of living only as prose.
