+# Gitzone CLI - Development Hints
+
 * the cli of the git.zone project.
+
+## Project Overview
+
+Gitzone CLI (`@git.zone/cli`) is a comprehensive toolbelt for streamlining local development cycles. It provides utilities for:
+- Project initialization and templating (via smartscaf)
+- Code formatting and standardization
+- Version control and commit management
+- Docker and CI/CD integration
+- Meta project management
+
+## Architecture
+
+### Core Structure
+- Main CLI entry: `cli.ts` / `cli.child.ts`
+- Modular architecture with separate modules in `ts/mod_*` directories
+- Each module handles specific functionality (format, commit, docker, etc.)
+- Extensive use of plugins pattern via `plugins.ts` files
+
+### Configuration Management
+- Uses `npmextra.json` for all tool configuration
+- Configuration stored under `gitzone` key in npmextra
+- No separate `.gitzonerc` file - everything in npmextra.json
+- Project type and module metadata also stored in npmextra
+
+### Format Module (`mod_format`) - SIGNIFICANTLY ENHANCED
+
+The format module is responsible for project standardization:
+
+#### Current Modules:
+1. **cleanup** - Removes obsolete files (yarn.lock, tslint.json, etc.)
+2. **copy** - File copying with glob patterns (fully implemented)
+3. **gitignore** - Creates/updates .gitignore from templates
+4. **license** - Checks dependency licenses for compatibility
+5. **npmextra** - Manages project metadata and configuration
+6. **packagejson** - Formats and updates package.json
+7. **prettier** - Applies code formatting with batching
+8. **readme** - Ensures readme files exist
+9. **templates** - Updates project templates based on type
+10. **tsconfig** - Formats TypeScript configuration
+
+#### Execution Order (Dependency-Based):
+- Modules are now executed in parallel groups based on dependencies
+- Independent modules run concurrently for better performance
+- Dependency analyzer ensures correct execution order
+
+### New Architecture Features
+
+1. **BaseFormatter Pattern**: All formatters extend abstract BaseFormatter class
+2. **FormatContext**: Central state management across all modules
+3. **FormatPlanner**: Implements plan → action workflow
+4. **RollbackManager**: Full backup/restore capabilities
+5. **ChangeCache**: Tracks file changes to optimize performance
+6. **DependencyAnalyzer**: Manages module execution order
+7. **DiffReporter**: Generates diff views for changes
+8. **FormatStats**: Comprehensive execution statistics
+
+### Key Patterns
+
+1. **Plugin Architecture**: All dependencies imported through `plugins.ts` files
+2. **Streaming**: Uses smartstream for file processing
+3. **Interactive Prompts**: smartinteract for user input
+4. **Enhanced Error Handling**: Comprehensive try-catch with automatic rollback
+5. **Template System**: Templates handled by smartscaf, not directly by gitzone
+6. **Type Safety**: Full TypeScript with interfaces and type definitions
+
+### Important Notes
+
+- `.nogit/` directory used for temporary/untracked files, backups, and cache
+- `.nogit/gitzone-backups/` stores format operation backups
+- `.nogit/gitzone-cache/` stores file change cache
+- Templates are managed by smartscaf - improvements should be made there
+- License checking configurable with exceptions support
+- All features implemented: `ensureDependency`, copy module, etc.
+
+## Recent Improvements (Completed)
+
+1. **Plan → Action Workflow**: Shows changes before applying them
+2. **Rollback Mechanism**: Full backup and restore on failures
+3. **Enhanced Configuration**: Granular control via npmextra.json
+4. **Better Error Handling**: Detailed errors with recovery options
+5. **Performance Optimizations**: Parallel execution and caching
+6. **Reporting**: Diff views, statistics, verbose logging
+7. **Architecture**: Clean separation of concerns with new classes
+
+## Development Tips
+
+- Always check readme.plan.md for ongoing improvement plans
+- Use npmextra.json for any new configuration options
+- Keep modules focused and single-purpose
+- Maintain the existing plugin pattern for dependencies
+- Test format operations on sample projects before deploying
+- Consider backward compatibility when changing configuration structure
+- Use BaseFormatter pattern for new format modules
+- Leverage FormatContext for cross-module state sharing
+
+## Configuration Examples
+
+```json
+{
+  "gitzone": {
+    "format": {
+      "interactive": true,
+      "parallel": true,
+      "showStats": true,
+      "cache": {
+        "enabled": true,
+        "clean": true
+      },
+      "rollback": {
+        "enabled": true,
+        "autoRollbackOnError": true,
+        "backupRetentionDays": 7
+      },
+      "modules": {
+        "skip": ["prettier"],
+        "only": [],
+        "order": []
+      },
+      "licenses": {
+        "allowed": ["MIT", "Apache-2.0"],
+        "exceptions": {
+          "some-package": "GPL-3.0"
+        }
+      }
+    }
+  }
+}
+```
+
+## CLI Usage
+
+```bash
+# Basic format
+gitzone format
+
+# Dry run to preview changes
+gitzone format --dry-run
+
+# Non-interactive mode
+gitzone format --yes
+
+# Plan only (no execution)
+gitzone format --plan-only
+
+# Save plan for later
+gitzone format --save-plan format.json
+
+# Execute saved plan
+gitzone format --from-plan format.json
+
+# Verbose mode
+gitzone format --verbose
+
+# Detailed diff views
+gitzone format --detailed
+
+# Rollback operations
+gitzone format --rollback
+gitzone format --rollback <operation-id>
+gitzone format --list-backups
+gitzone format --clean-backups
+```
+
+## Common Issues (Now Resolved)
+
+1. ✅ Format operations are now reversible with rollback
+2. ✅ Enhanced error messages with recovery suggestions
+3. ✅ All modules fully implemented (including copy)
+4. ✅ Dry-run capability available
+5. ✅ Extensive configuration options available
+
+## Future Considerations
+
+- Plugin system for custom formatters
+- Git hooks integration for pre-commit formatting
+- Advanced UI with interactive configuration
+- Format presets for common scenarios
+- Performance benchmarking tools
+
+## API Changes
+
+- smartfile API updated to use fs.* and memory.* namespaces
+- smartnpm requires instance creation: `new NpmRegistry()`
+- All file operations now use updated APIs
+- Type imports use `import type` for proper verbatim module syntax
