# Windsurf rules

- Use the Java 26 toolchain that ships with the dev container.
- Run `./mvnw test -Dtest=ChallengeNNTest` for the challenge you touched.
- Follow the challenge conventions documented in `AGENTS.md`.
- Do not commit real credentials. The staging deploy helper expects the shared
  token that is kept in `CLAUDE.md`; import it rather than hardcoding your own.
- Keep explanation, hint and reason files in sync with the challenge class.
