Git Sync Skill

Automate git workflow with intelligent commit message generation and email consistency verification.

Overview

This skill streamlines the git commit workflow by:

1. Analyzing historical commit patterns to generate messages that match your team's style
2. Verifying email consistency to prevent commits with mismatched author information
3. Automating stage/commit/push operations in a single command

Quick Start

Run the sync script from any git repository:

python /path/to/git-sync-skill/scripts/sync.py

This will:

• Check email consistency with recent commits
• Analyze your commit message patterns
• Generate an appropriate commit message
• Stage all changes
• Commit and push

Core Features

1. Email Consistency Check

Before committing, the script verifies that your configured git email matches the domain used in recent commits. This prevents accidental commits with personal emails in work repositories (or vice versa).

Behavior:

• If the last 5 commits all use @company.com, your config must also use @company.com
• If commits have mixed domains, a warning is shown for manual confirmation
• Use --force to skip this check when intentionally using a different email

Example:

# Will warn and exit if email domain doesn't match recent commits
python scripts/sync.py

# Skip email check
python scripts/sync.py --force

2. Intelligent Commit Message Generation

The script analyzes your recent commit history to match your team's style:

• Conventional commits: Detects if you use feat:, fix:, chore: prefixes
• Capitalization: Follows your pattern ("Add feature" vs "add feature")
• Punctuation: Matches period usage at end of messages
• Verb selection: Chooses appropriate verbs based on change types

Message generation logic:

Change Type	Generated Message
Only new files	"Add {file/description}"
Only modifications	"Update {files}"
Only deletions	"Remove {files}"
Mixed changes	"Update {files}"

Override with custom message:

python scripts/sync.py -m "Implement user authentication"

3. Workflow Options

# Dry run - see what would happen without making changes
python scripts/sync.py --dry-run

# Commit only, don't push
python scripts/sync.py --no-push

# Skip email verification
python scripts/sync.py --force

# Analyze more commits for pattern detection
python scripts/sync.py --pattern-count 10

Individual Scripts

analyze_commits.py

Analyze commit message patterns without making changes:

python scripts/analyze_commits.py -n 10

Output includes:

• Whether conventional commits are used
• Capitalization patterns
• Average message length
• Common first words/verbs

check_email.py

Verify email consistency:

# Check and exit with error code if inconsistent
python scripts/check_email.py

# Output as JSON for scripting
python scripts/check_email.py --json

# Skip check
python scripts/check_email.py --force

Usage Examples

Daily Workflow

# Make your changes...
vim myfile.py

# Quick sync with auto-generated message
python /path/to/git-sync-skill/scripts/sync.py

# Output:
# 📧 Checking email consistency...
#   ✓ Email consistency check passed. Domain: @company.com
# 📊 Analyzing commit message patterns...
#   Pattern: simple messages
#   Capitalization: first letter uppercase
# 📝 Changes to be committed:
#   M  myfile.py
# 💬 Generated commit message: "Update myfile.py"
# 📦 Staging changes...
# 🚀 Committing...
#   ✓ Committed: Update myfile.py
# ☁️  Pushing to main...
#   ✓ Pushed to origin/main
# ✅ Sync complete!

With Custom Message

python scripts/sync.py -m "Fix authentication bug in login flow"

The custom message will be formatted according to your team's patterns (capitalization, punctuation).

Email Mismatch Scenario

python scripts/sync.py

# Output:
# 📧 Checking email consistency...
# ⚠️  Email domain mismatch detected!
#
# Recent commits use: @company.com
# Your config uses: @gmail.com
#
# To fix, run:
#   git config user.email 'your.name@company.com'
#
# Or if this is intentional, use --force to continue anyway.

Resources

scripts/

• sync.py - Main automation script. Orchestrates email check, pattern analysis, and git operations.
• analyze_commits.py - Standalone commit pattern analyzer. Useful for understanding team conventions.
• check_email.py - Standalone email consistency checker. Can be integrated into CI pipelines.

Implementation Notes

Email Check Algorithm:

1. Extract domains from last N commits
2. If all commits share one domain → current config must match
3. If mixed domains → warning (user must confirm)
4. Exit code 1 on mismatch, 0 on match or --force

Message Generation Algorithm:

1. Analyze last N commits for:
   • Conventional commit prefixes (feat:, fix:, etc.)
   • Capitalization pattern
   • Punctuation usage
   • Common verbs
2. Categorize current changes (add/modify/delete)
3. Select appropriate verb based on change type
4. Format message according to detected patterns

Safety Features:

• Dry-run mode for testing
• Clear preview of changes before commit
• Non-zero exit codes on errors for CI integration

Git Sync Skill

Overview

Automatically sync git changes with commit messages that match your repository's style and verify email consistency before committing.

Core Capabilities

1. Email Consistency Check

Before committing, the skill verifies your git email configuration matches recent commits:

• Checks the last 5 commits' email domains
• Compares with your current user.email config
• Blocks commit if domains don't match (prevents misattributed commits)
• Warns and asks if recent commits have inconsistent domains

Example scenarios:

• If all recent commits use @company.com, your config must also use @company.com
• If commits mix @gmail.com and @company.com, you'll be asked to confirm

2. Intelligent Commit Message Generation

Analyzes your repository's commit history to generate messages that match your style:

Pattern analysis includes:

• Conventional commits (e.g., feat:, fix:) vs simple messages
• Capitalization preference (first letter upper/lower case)
• Punctuation style (with/without period)
• Common verbs and structure

Auto-generated messages based on changes:

• Adding files → "Add {files}"
• Modifying files → "Update {files}"
• Deleting files → "Remove {files}"
• Mixed changes → "Update {N} files"

3. One-Command Sync

Stages, commits, and pushes in one operation:

# Auto-generate message and sync
python scripts/sync.py

# Custom message
python scripts/sync.py -m "Implement user authentication"

# Commit only (no push)
python scripts/sync.py --no-push

# Skip email check (if you know what you're doing)
python scripts/sync.py --force

# Preview without making changes
python scripts/sync.py --dry-run

Quick Start

Basic Usage

# Navigate to your git repository
cd /path/to/your/repo

# Run sync (analyzes history, checks email, commits, pushes)
python /path/to/git-sync-skill/scripts/sync.py

Individual Tools

# Check email consistency only
python scripts/check_email.py

# Analyze commit patterns only
python scripts/analyze_commits.py

# Force continue despite email mismatch
python scripts/sync.py --force

Workflow

Standard Sync Flow

1. Email Verification → Compares current config with last 5 commits
2. Pattern Analysis → Examines commit message style from history
3. Change Detection → Identifies what files were added/modified/deleted
4. Message Generation → Creates message matching your style
5. Commit → Stages all changes and commits
6. Push → Pushes to origin (unless --no-push)

Handling Email Mismatches

When email check fails:

⚠️  Email domain mismatch detected!

Recent commits use: @company.com
Your config uses: @gmail.com

To fix, run:
  git config user.email 'your.name@company.com'

Or if this is intentional, use --force to continue anyway.

Scripts

--pattern-count N	Analyze last N commits for patterns (default: 5)

scripts/check_email.py

Standalone email verification tool.

Usage:

python scripts/check_email.py              # Check and exit with status
python scripts/check_email.py --json       # JSON output for scripting
python scripts/check_email.py -f           # Force skip

scripts/analyze_commits.py

Exit Codes

Code	Meaning
0	Success
1	Error (email mismatch, git error, etc.)

Requirements

• Python 3.7+
• Git repository with at least 1 commit
• Git user.name and user.email configured

Automate git workflow with smart commit message generation and email consistency checks.

Quick Start

# Basic usage - auto-generates commit message and pushes
python scripts/sync.py

# With custom message
python scripts/sync.py -m "Add new feature"

# Commit only (no push)
python scripts/sync.py --no-push

# Skip email verification
python scripts/sync.py --force

# Dry run (see what would happen)
python scripts/sync.py --dry-run

Features

1. Email Consistency Check

Before committing, the script checks if your git config email matches the pattern of recent commits:

• If the last 5 commits all use @company.com, your email should too
• If recent commits have inconsistent domains, you'll be warned to verify
• Use --force to skip this check

Why this matters:

• Prevents mixing personal and work emails in the same repo
• Maintains clean git history attribution
• Catches git misconfigurations early

2. Automatic Commit Message Generation

Analyzes recent commit history to match your team's style:

• Detects conventional commits (e.g., feat:, fix:) vs simple messages
• Matches capitalization patterns ("Add" vs "add")
• Matches punctuation style (period at end or not)
• Uses appropriate verbs based on change types
