name: latitude-repo-hygiene description: Repo hygiene rules for Latitude. Prevents generated/extracted artifacts from entering commits, release branches, tags, or jars. Provides the canonical ignore list and cleanup commands.

Latitude — Repo Hygiene (Authoritative)

This skill prevents:

• accidental commits of extracted Minecraft sources
• accidental commits of tooling folders (Windsurf skills, caches)
• polluted feature branches being used for releases
• confusion around huge diffs unrelated to mod code

---

Never-commit folders (absolute)

These must never be committed to any release branch (and should generally be ignored everywhere):

• _mcsrc_extract/
• run/ (worlds, logs, caches)
• logs/
• .gradle/
• .gradle-user-home/
• build/
• out/
• .idea/
• .vscode/
• .classpath
• .project
• .settings/
• *.iml

Tooling:

• .windsurf/ (skills, internal state) — never ship inside jars
• any processedMods/ cache folder under run/.fabric/

OS noise:

• Thumbs.db
• .DS_Store

If any of these appear in git status, STOP and fix before continuing.

---

Release branch hygiene rules

• 1.21.11 releases must be tagged from main
• 1.21.1 releases must be tagged from compat/1.21.1
• Do not tag releases from feature/* branches, especially if they contain any forbidden folders.

---

Required .gitignore policy

The repo must include ignore rules for every “never-commit folder” above.

If the assistant proposes adding a generated folder to the repo, it must justify why and confirm it is safe for release.

---

Cleanup commands (PowerShell)

Remove generated artifacts

Remove-Item -Recurse -Force .\build -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force .\.gradle -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force .\.gradle-user-home -ErrorAction SilentlyContinue
Remove-Item -Recurse -Force .\run\.fabric\processedMods\* -ErrorAction SilentlyContinue

If forbidden files were accidentally staged

git restore --staged .
git restore .

If forbidden files were committed (do not panic)

Preferred fix:

• revert the commit on the branch
• or rewrite history only if absolutely necessary and coordinated

---

Jar safety check (must pass before upload)

Always check the jar you will upload:

jar tf .\build\libs\<YOUR_JAR_NAME>.jar | findstr /I "_mcsrc_extract .windsurf SKILL.md com/mojang blaze3d"

Pass criteria:

• no matches.

---

Required assistant output when repo pollution is detected

The assistant must:

1. identify the forbidden path(s)
2. provide the smallest safe cleanup action
3. ensure .gitignore prevents recurrence
4. ensure release tags are on clean branches
