+# CI pipeline for the Skelly Godot project

+# Code quality checks (formatting, linting, testing) run as independent jobs
+# in parallel. Uses tools/run_development.py for consistency with local development.
+#
+# Features:
+# - Independent job execution (no dependencies between format/lint/test)
+# - Automatic code formatting with commit back to branch
+# - Error reporting and PR comments
+# - Manual execution with selective step skipping

+# Development Tools
+
+Development workflow tools for the Skelly Godot project.
+
+Python script that handles code formatting, linting, and testing.
+
+## Quick Start
+
+Run all development checks (recommended for pre-commit):
+```bash
+run_dev.bat
+```
+
+Runs code formatting → linting → testing.
+
+## Available Commands
+
+### Main Unified Script
+- **`run_dev.bat`** - Main unified development script with all functionality
+
+### Individual Tools (Legacy - redirect to unified script)
+- **`run_all.bat`** - Same as `run_dev.bat` (legacy compatibility)
+- **`run_lint.bat`** - Run only linting (redirects to `run_dev.bat --lint`)
+- **`run_format.bat`** - Run only formatting (redirects to `run_dev.bat --format`)
+- **`run_tests.bat`** - Run only tests (redirects to `run_dev.bat --test`)
+
+## Usage Examples
+
+```bash
+# Run all checks (default behavior)
+run_dev.bat
+
+# Run only specific tools
+run_dev.bat --lint
+run_dev.bat --format
+run_dev.bat --test
+
+# Run custom workflow steps
+run_dev.bat --steps format lint
+run_dev.bat --steps format test
+
+# Show help
+run_dev.bat --help
+```
+
+## What Each Tool Does
+
+### 🔍 Linting (`gdlint`)
+- Checks GDScript code for style violations
+- Enforces naming conventions
+- Validates code structure and patterns
+- **Fails the workflow if errors are found**
+
+### 🎨 Formatting (`gdformat`)
+- Automatically formats GDScript code
+- Ensures consistent indentation and spacing
+- Fixes basic style issues
+- **Fails the workflow if files cannot be formatted**
+
+### 🧪 Testing (`godot`)
+- Runs all test files in `tests/` directory
+- Executes Godot scripts in headless mode
+- Reports test results and failures
+- **Continues workflow even if tests fail** (for review)
+
+## Dependencies
+
+The script automatically checks for and provides installation instructions for:
+- Python 3.x
+- pip
+- Godot Engine (for tests)
+- gdtoolkit (gdlint, gdformat)
+
+## Output Features
+
+- Colorized output
+- Emoji status indicators
+- Tool summaries
+- Execution time tracking
+- Warning suppression
+
+## Development Workflow
+
+1. **Before committing**: Run `run_dev.bat` to ensure code quality
+2. **Fix any linting errors** - the workflow will abort on errors
+3. **Review any test failures** - tests don't abort workflow but should be addressed
+4. **Commit your changes** once all checks pass
+
+## Integration
+
+Works with:
+- Git hooks (pre-commit)
+- CI/CD pipelines
+- IDE integrations
+- Manual development workflow
+
+Legacy batch files remain functional.

+Development workflow runner for the Skelly Godot project.
