Git Workflow

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Git Workflow Guidelines

Auto-activate when: Working with .gitignore, .gitattributes, .git/, or when user mentions commit, push, git, version control, pull request, branch, merge, staging changes, filter-branch, rebase, reset, or history rewrite. Should also activate when bash commands contain git (requires conversation parsing).

Comprehensive git workflow principles for all git operations.

Critical Rules

Push Behavior

MUST NOT push without explicit "push" keyword. Examples: "commit my changes" → NO push, "commit and push" → YES push. After committing without push, inform: "Changes committed locally. Run 'git push' to push to remote."

When to Commit

Only commit when explicitly requested. MUST NOT commit proactively.

Security First

MUST scan for secrets. If found, STOP and refuse to commit.

Critical patterns:

• AWS keys (AKIA, ABIA, ACCA, ASIA prefixes)
• GitHub tokens (ghp_, gho_, ghu_, ghs_, ghr_)
• Anthropic keys (sk-ant-)
• OpenAI keys (sk-proj-, sk-)
• Generic API keys (API_KEY=, APIKEY=, api_key=)
• Tokens (TOKEN=, ACCESS_TOKEN=, Bearer )
• Passwords (PASSWORD=, pwd=, passwd=, secret=)
• Private keys (-----BEGIN, -----BEGIN RSA, -----BEGIN OPENSSH)
• Connection strings (mongodb://, postgres://, mysql://)
• High-entropy strings (32+ char random alphanumeric)

If detected:

1. Show files/lines
2. Suggest .gitignore
3. Recommend env vars or secret manager
4. Refuse even if insisted

Git-Crypt Exception

Files marked with filter=git-crypt in .gitattributes are exempt from security scanning.

Why safe:

• Automatically encrypted before commit
• Plaintext in working directory, encrypted in repository
• Explicit protection declaration

Detection: Check if file matches patterns in .gitattributes with filter=git-crypt directive.

Example .gitattributes:

secrets/*.json filter=git-crypt diff=git-crypt
*.key filter=git-crypt diff=git-crypt
.env.production filter=git-crypt diff=git-crypt

Validation:

• Verify git-crypt is initialized: git-crypt status
• If not initialized, warn user but don't block

Commit Organization

Types (Conventional Commits)

Breaking Changes

Use ! after type: feat!: remove deprecated API Or add footer: BREAKING CHANGE: description

Atomic Commits

Each commit should:

• Do ONE thing only
• Leave codebase in working state
• Be independently revertable
• Use git add -p to stage partial files

Grouping Strategy

• Single commit: All changes closely related
• Multiple commits: Different types or purposes
• Follow project's existing commit style (check git log)

Commit Message Format

Use HEREDOC for multi-line messages:

git commit -m "$(cat <<'EOF'
type: concise summary

Optional details focusing on why, not what
EOF
)"

Focus on "why" rather than "what". Keep summary to 1-2 sentences.

Human-Like Commit Style

To avoid obvious AI patterns (while keeping good documentation):

• No emojis: MUST NOT use ✅❌⚠️ℹ️ or any emojis in commits
• Natural grammar: Use natural phrasing, don't worry about perfect grammar
• Avoid excessive structure: Limit section headers (one "Changes:" section is fine, but avoid multiple like "Technical improvements:", "Benefits:", "Result:", etc.)
• Detail when needed: Include relevant details, but focus on what and why, not exhaustive documentation of every file

Code Comment Guidelines

When writing code in commits, avoid AI patterns:

• No border comments: Don't use # ===...=== or # ---...--- style separators
• No "WHY" labels: Instead of "# WHY: reason", just explain naturally: "# Reason for this..."
• No emojis in code: MUST NOT use ✅❌⚠️ℹ️ in comments or strings
• Brief explanations: Comment purpose, not every detail
• Casual tone: "This handles..." not "This implementation provides comprehensive handling of..."

Workflow Process

1. Security scan - Check for secrets first
2. Analyze - Run git status, diff, log in parallel
3. Group - Organize by commit type
4. Commit - Use HEREDOC format
5. Verify - Ensure clean status
6. Push - Only if explicitly requested

Safety Rules

• MUST NOT skip hooks (--no-verify) without explicit request
• Only amend your own unpushed commits
• MUST check authorship before amending
• If pre-commit hooks modify files, only amend if safe

Force Push - AVOID

Never use git push --force or --force-with-lease unless explicitly requested by user.

Why force push is dangerous:

• Rewrites published history others may have pulled
• Can cause collaborators to lose work
• Breaks CI/CD pipelines referencing old commits
• Makes debugging harder (commit SHAs change)

Common mistakes that lead to force push:

• Amending after push → just make a new commit instead
• Rebasing a pushed branch → merge instead, or only rebase unpushed commits
• "Cleaning up" commit history → leave it alone once pushed

If you pushed a commit, it's done. Fix mistakes with new commits, not by rewriting history.

Destructive Operations - BANNED

MUST NOT Use These Commands

• git filter-branch - BANNED (deprecated by git project, use git-filter-repo)
• git gc --prune=now - BANNED (bypasses 14-day safety window)
• git gc --aggressive - BANNED (makes recovery harder)
• git reset --hard - BANNED without explicit user request
• git clean -fd - BANNED without explicit user request
• git add -f on gitignored files - BANNED (causes data loss later)

If User Asks to Remove Files from Git History

1. STOP - Do not use filter-branch (it is deprecated)
2. Tell user: "git-filter-repo is the recommended tool. It requires a fresh clone."
3. Ask: "Do you have backups? Assume any secrets are already compromised."
4. Suggest: Rotate credentials first, then rewrite history
5. If proceeding: User must install git-filter-repo and work on fresh clone
6. MUST NOT run gc --prune after - default 14-day window allows recovery

If File is in .gitignore But Needs Committing

1. STOP - Do not use git add -f
2. Better: Add exception to .gitignore using ! prefix

   # In .gitignore:
   *.log
   !important.log  # Exception - this file WILL be tracked
   

3. Or: Remove file pattern from .gitignore entirely
4. Then: git add <file> normally

Undo Accidental Force-Add

git rm --cached <file>  # Removes from git, keeps on disk

Recovery Options (before gc --prune=now)

git reflog                    # Find lost commits
git fsck --unreachable        # Find orphaned objects
git fsck --lost-found         # Recover to .git/lost-found/

Philosophy

This skill defines the principles. The /commit command implements the procedural execution. Security always comes first, commits require explicit request, and pushes require the "push" keyword.
