+# Agent Guidelines for QuickGit
+
+This document provides coding agents with essential information about the QuickGit codebase, including build commands, code style, and architectural conventions.
+
+---
+
+## Project Overview
+
+**QuickGit** is a modular CLI Git management tool written in Python 3.6+. It simplifies Git operations through an interactive menu system with colorful console output.
+
+**Key Technologies:**
+- Pure Python 3.6+ (no external dependencies)
+- Standard library only: `subprocess`, `os`, `datetime`, `sys`
+- Cross-platform support: Windows, Linux, macOS
+- ANSI escape codes for colorful console output
+
+---
+
+## Build, Run, and Test Commands
+
+### Running the Application
+
+```bash
+# Recommended: Run the modular version
+python quickgit.py        # Windows
+python3 quickgit.py       # Linux/macOS
+
+# Platform-specific launchers:
+run.bat                   # Windows (sets UTF-8 encoding)
+./run.sh                  # Linux/macOS (first run: chmod +x run.sh)
+
+# Legacy: Run the single-file version
+python mengya_git_manager.py
+```
+
+### Testing
+
+**No formal test suite exists yet.** Manual testing workflow:
+
+1. **Test in a clean directory:**
+   ```bash
+   cd /path/to/test/directory
+   python E:\SmyProjects\Python\脚本\萌芽一键Git管理\quickgit.py
+   ```
+
+2. **Test each menu option:**
+   - Option 1: Initialize Git repo
+   - Option 2: Commit and push (requires changes)
+   - Option 3: Pull from remote
+   - Option 4: View status
+   - Option 5: Manage remotes
+   - Option 6: Exit
+
+3. **Verify console output:**
+   - Check colors render correctly
+   - Ensure ASCII dividers align (60 chars wide)
+   - No encoding errors with Chinese characters
+
+### Linting and Code Quality
+
+```bash
+# No formal linting configured yet
+# Recommended tools for future use:
+# pip install pylint black mypy
+
+# Type checking (Python 3.10+ syntax used):
+# mypy quickgit/
+
+# Formatting:
+# black quickgit/ --line-length 100
+
+# Linting:
+# pylint quickgit/
+```
+
+---
+
+## Code Style Guidelines
+
+### File Organization
+
+**Module Structure:**
+```
+quickgit/
+├── __init__.py          # Package init (empty)
+├── config.py            # Configuration constants
+├── utils.py             # Utilities (Colors, CommandExecutor, OutputFormatter, InputValidator, PlatformUtils)
+├── git_operations.py    # Git command wrapper
+├── remote_manager.py    # Remote repository management
+└── ui.py                # User interface and menu system
+```
+
+**Principle:** Each module has a single, well-defined responsibility.
+
+### Import Conventions
+
+**Order:**
+1. Standard library imports
+2. Relative imports from `quickgit` package
+
+**Style:**
+```python
+# Standard library
+import os
+import sys
+from datetime import datetime
+
+# Internal modules (relative imports preferred)
+from .utils import CommandExecutor, OutputFormatter, Colors
+from .config import Config
+```
+
+**Lazy imports for circular dependency avoidance:**
+```python
+def some_function():
+    from .utils import Colors  # Import inside function if needed
+    print(f"{Colors.CYAN}Message{Colors.ENDC}")
+```
+
+### Type Hints
+
+**Required for all function signatures:**
+
+```python
+# Good
+def run(command: str, show_output: bool = True) -> tuple[bool, str]:
+    """Execute command and return (success, output)"""
+    pass
+
+def get_remotes(self) -> list[str]:
+    """Get all remote repositories"""
+    pass
+
+def confirm(prompt: str, default: bool = False) -> bool:
+    """Get user confirmation"""
+    pass
+```
+
+**Note:** Uses Python 3.10+ syntax (`list[str]`, `tuple[bool, str]`). For Python 3.6-3.9 compatibility, use:
+```python
+from typing import List, Tuple
+def get_remotes(self) -> List[str]: ...
+```
+
+### Naming Conventions
+
+- **Classes:** `PascalCase` (e.g., `GitOperations`, `RemoteManager`)
+- **Functions/Methods:** `snake_case` (e.g., `add_github_remote`, `show_main_menu`)
+- **Constants:** `UPPER_SNAKE_CASE` (e.g., `DEFAULT_BRANCH`, `GITEA_HOST`)
+- **Private methods:** Prefix with `_` (e.g., `_create_gitignore`, `_add_remote`)
+- **Module-level:** Avoid global variables; use `Config` class for constants
+
+### Formatting and Whitespace
+
+- **Line length:** Aim for 100 characters max (not strictly enforced)
+- **Indentation:** 4 spaces (no tabs)
+- **Blank lines:** 2 between top-level definitions, 1 between methods
+- **Strings:** Use double quotes `"` for user-facing text, either for code strings
+
+### Error Handling
+
+**Always provide user-friendly feedback:**
+
+```python
+# Good
+try:
+    with open('.gitignore', 'w', encoding='utf-8') as f:
+        f.write(Config.GITIGNORE_TEMPLATE)
+    OutputFormatter.success(".gitignore文件创建成功")
+except Exception as e:
+    OutputFormatter.error(f".gitignore文件创建失败: {str(e)}")
+```
+
+**Command execution pattern:**
+
+```python
+success, output = self.executor.run("git status", show_output=False)
+if success:
+    OutputFormatter.success("操作成功")
+else:
+    OutputFormatter.error("操作失败")
+    return False
+```
+
+**Never swallow exceptions silently.** Always log errors via `OutputFormatter.error()`.
+
+---
+
+## Console Output Guidelines
+
+### Critical Rules
+
+1. **NO EMOJI CHARACTERS** - They cause Windows console encoding errors
+2. **NO UNICODE BOX-DRAWING** (`┌─┐│└┘╔═╗║╚╝`) - They misalign across terminals
+3. **Use ASCII only:** `=`, `-`, `·` for dividers
+4. **Status indicators:** `[√]`, `[×]`, `[i]`, `[!]`, `[>]` instead of Unicode symbols
+5. **Fixed width:** All dividers are exactly 60 characters wide
+
+### Color Usage
+
+**Color scheme:**
+```python
+Colors.BRIGHT_GREEN    # Success messages
+Colors.BRIGHT_RED      # Errors
+Colors.BRIGHT_CYAN     # Info/prompts
+Colors.BRIGHT_YELLOW   # Warnings/section headers
+Colors.BRIGHT_MAGENTA  # Main headers
+Colors.WHITE           # General text
+```
+
+**Always reset colors:**
+```python
+print(f"{Colors.BRIGHT_GREEN}Success{Colors.ENDC}")  # ENDC resets to default
+```
+
+### Output Formatting Functions
+
+```python
+OutputFormatter.header("Title")          # Top-level header (cyan/magenta)
+OutputFormatter.section("Section")       # Section header (yellow/blue)
+OutputFormatter.divider()                # 60-char line: ----------
+OutputFormatter.success("Done!")         # [√] Green success
+OutputFormatter.error("Failed!")         # [×] Red error
+OutputFormatter.info("Note...")          # [i] Cyan info
+OutputFormatter.warning("Warning!")      # [!] Yellow warning
+OutputFormatter.step(1, "Step one")      # [1] Step indicator
+OutputFormatter.menu_item(1, "Option")   # [1] Menu item
+```
+
+---
+
+## Git Operations Patterns
+
+### SSH Configuration
+
+- **GitHub:** `git@github.com:shumengya/{repo}.git`
+- **Gitea:** `ssh://git@repo.shumengya.top:8022/{user}/{repo}.git`
+
+All remote operations use SSH (no HTTPS).
+
+### Command Execution
+
+**Pattern for all Git commands:**
+
+```python
+# 1. Show status indicator
+OutputFormatter.status('running', "Pushing to remote...")
+
+# 2. Execute command (capture output)
+success, output = self.executor.run("git push origin main", show_output=True)
+
+# 3. Provide feedback
+if success:
+    OutputFormatter.success("Push successful")
+else:
+    OutputFormatter.error("Push failed")
+
+return success
+```
+
+---
+
+## Adding New Features
+
+### Checklist for New Functionality
+
+1. **Determine the module:** Where does this feature belong?
+   - Git operations → `git_operations.py`
+   - Remote management → `remote_manager.py`
+   - UI/menus → `ui.py`
+   - Config/constants → `config.py`
+   - Utilities → `utils.py`
+
+2. **Add type hints** to all functions
+
+3. **Use OutputFormatter** for all user-facing messages
+
+4. **Test manually** in a clean directory
+
+5. **Update README.md** if adding user-facing features
+
+---
+
+## Common Gotchas
+
+1. **Windows path handling:** Use `os.path` or `pathlib` for cross-platform paths
+2. **Encoding:** All file I/O must specify `encoding='utf-8'`
+3. **Subprocess:** Always use `encoding='utf-8', errors='ignore'` in `subprocess.run()`
+4. **Git output:** Some commands have localized output; parse carefully
+5. **Empty commits:** Check `git status --short` before committing
+6. **Divider width:** Always use exactly 60 characters for consistency
+7. **Platform differences:**
+   - Use `python3` on Linux/macOS, `python` on Windows
+   - Shell scripts: `.sh` for Unix, `.bat` for Windows
+   - Clear screen: Use `PlatformUtils.clear_screen()` for cross-platform support
+
+---
+
+## Platform-Specific Notes
+
+### Windows
+- Use `run.bat` launcher to set UTF-8 encoding (`chcp 65001`)
+- ANSI colors supported on Windows 10+ by default
+- Python command: `python` (not `python3`)
+
+### Linux/macOS
+- Use `run.sh` launcher (requires `chmod +x run.sh` first time)
+- Ensure terminal supports UTF-8 encoding
+- Python command: `python3` (not `python`)
+- Shell uses bash (shebang: `#!/bin/bash`)
+
+### Cross-Platform Code
+- Use `PlatformUtils.is_windows()`, `is_linux()`, `is_mac()` for platform detection
+- Use `PlatformUtils.clear_screen()` instead of `os.system('cls')` or `os.system('clear')`
+- Always use `os.path.join()` or `pathlib.Path` for file paths
+
+---
+
+## Future Development Notes
+
+**Planned features (not yet implemented):**
+- Branch management
+- Tag management
+- Conflict resolution assistance
+- Custom configuration file support
+- Batch operations for multiple repositories
+- Formal test suite (pytest recommended)
+- CI/CD pipeline
+
+**When implementing these:**
+- Follow the existing modular architecture
+- Add to appropriate module (or create new module if needed)
+- Maintain the colorful, user-friendly console output style
+- Keep Windows compatibility in mind
