--- name: git-operator description: Rules and procedures for Git operations (add, branch, commit, push). Use when performing git add, git commit, git push, or creating branches. --- # Git Operator This skill defines rules and procedures for Git operations. ## Prohibited Operations The following operations must never be performed. ### git commit --amend Do not modify commits once created. Address issues with new commits. ```bash # Prohibited git commit --amend git commit --amend -m "..." ``` ### git push --force Force push is prohibited. ```bash # Prohibited git push --force git push -f git push --force-with-lease ``` ### Other History-Rewriting Operations The following operations are also prohibited. - `git rebase` operations that rewrite history - `git reset --hard` operations that erase history - Any other operations that modify pushed commits These operations rewrite Git history and cause problems in collaborative work: other developers' work may be lost, history integrity may be compromised, and merge conflicts become more likely. Once a commit is pushed, fix issues with new commits instead of modifying history. --- ## Staging Stage only task-related files. Do not use `git add .` or `git add -A` without explicit confirmation. ```bash git status # Run this first git add # Stage specific files ``` Before staging, verify: - No secrets (.env, credentials.json, API keys) - No unrelated changes included ## Branch Creation Branch names must be in kebab-case. Good: `add-user-authentication`, `fix-login-bug`, `update-readme` Bad: `addUserAuthentication`, `Add_User_Auth`, `ADD-USER-AUTH` ```bash git switch -c ``` ## Commit Follow Conventional Commits format. ``` (): [optional body] ``` ### Types - `feat`: New feature - `fix`: Bug fix - `docs`: Documentation only changes - `style`: Changes that do not affect the meaning of the code - `refactor`: Code changes that neither fix a bug nor add a feature - `perf`: Code changes that improve performance - `test`: Adding or modifying tests - `build`: Changes that affect the build system or external dependencies - `ci`: Changes to CI configuration files or scripts - `chore`: Other changes (not modifying src or test) ### Procedure Analyse staged changes to create a message focusing on "why" rather than "what". ```bash git diff --cached # Review staged changes git commit -m "(): " ``` Good example: ``` fix(auth): prevent session timeout on mobile Users reported being logged out after 5 minutes on mobile. Root cause was incorrect token refresh interval. ``` Bad example: ``` fixed bug ``` For multi-line messages, use HEREDOC: ```bash git commit -m "$(cat <<'EOF' (): EOF )" ``` ## Push ### Pre-push Verification Run these commands before pushing: ```bash git log --oneline -5 # Verify recent commits git branch -vv # Verify current branch and tracking git status # Ensure working directory is clean ``` Proceed only after reviewing the output. ### Procedure For new branches: ```bash git push -u origin ``` For existing remote tracking branches: ```bash git push ```
