+usage: /workflow:gemini-init [--output=<path>] [--preview]

+
+# Gemini Initialization Command
+
+## Overview
+Initializes Gemini CLI configuration for the workspace by:
+1. Analyzing current workspace using `get_modules_by_depth.sh` to identify technology stacks
+2. Generating `.geminiignore` file with filtering rules optimized for detected technologies
+3. Creating `.gemini` configuration file with contextfilename and other settings
+
+## Core Functionality
+
+### Configuration Generation
+1. **Workspace Analysis**: Runs `get_modules_by_depth.sh` to analyze project structure
+2. **Technology Stack Detection**: Identifies tech stacks based on file extensions, directories, and configuration files
+3. **Gemini Config Creation**: Generates `.gemini` file with contextfilename and workspace-specific settings
+4. **Ignore Rules Generation**: Creates `.geminiignore` file with filtering patterns for detected technologies
+
+### Generated Files
+
+#### .gemini Configuration File
+Contains Gemini CLI contextfilename setting:
+```json
+{
+  "contextfilename": "CLAUDE.md"
+}
+```
+
+#### .geminiignore Filter File
+Uses gitignore syntax to filter files from Gemini CLI analysis

+
+## Command Options
+
+### Basic Usage
+```bash
+/workflow:gemini-init
+```
+- Analyzes workspace and generates `.gemini` and `.geminiignore` in current directory
+- Creates backup of existing files if present
+- Sets contextfilename to "CLAUDE.md" by default
+
+### Preview Mode
+```bash
+/workflow:gemini-init --preview
+```
+- Shows what would be generated without creating files
+- Displays detected technologies, configuration, and ignore rules
+
+### Custom Output Path
+```bash
+/workflow:gemini-init --output=.config/
+```
+- Generates files in specified directory
+- Creates directories if they don't exist
+
+## Implementation Process
+
+### Phase 1: Workspace Analysis
+1. Execute `get_modules_by_depth.sh json` to get structured project data
+2. Parse JSON output to identify directories and files
+3. Scan for technology indicators:
+   - Configuration files (package.json, requirements.txt, etc.)
+   - Directory patterns (src/, tests/, etc.)
+   - File extensions (.js, .py, .java, etc.)
+4. Detect project name from directory name or package.json
+
+### Phase 2: Technology Detection
+```bash
+# Technology detection logic
+detect_nodejs() {
+    [ -f "package.json" ] || find . -name "package.json" -not -path "*/node_modules/*" | head -1
+}
+
+detect_python() {
+    [ -f "requirements.txt" ] || [ -f "setup.py" ] || [ -f "pyproject.toml" ] || \
+    find . -name "*.py" -not -path "*/__pycache__/*" | head -1
+}
+
+detect_java() {
+    [ -f "pom.xml" ] || [ -f "build.gradle" ] || \
+    find . -name "*.java" | head -1
+}
+```
+
+### Phase 3: Configuration Generation
+1. **Gemini Config (.gemini)**:
+   - Generate simple JSON config with contextfilename setting
+   - Set contextfilename to "CLAUDE.md" by default
+
+### Phase 4: Ignore Rules Generation
+1. Start with base rules (always included)
+2. Add technology-specific rules based on detection
+3. Add workspace-specific patterns if found
+4. Sort and deduplicate rules
+
+### Phase 5: File Creation
+1. **Generate .gemini config**: Write JSON configuration file
+2. **Generate .geminiignore**: Create organized ignore file with sections
+3. **Create backups**: Backup existing files if present
+4. **Validate**: Check generated files are valid
+
+## Generated File Format
+
+```
+# .geminiignore
+# Generated by Claude Code workflow:gemini-ignore command
+# Creation date: 2024-01-15 10:30:00
+# Detected technologies: Node.js, Python, Docker
+#
+# This file uses gitignore syntax to filter files for Gemini CLI analysis
+# Edit this file to customize filtering rules for your project

+
+## Error Handling
+
+### Missing Dependencies
+- If `get_modules_by_depth.sh` not found, show error with path to script
+- Gracefully handle cases where script fails
+
+### Write Permissions
+- Check write permissions before attempting file creation
+- Show clear error message if cannot write to target location
+
+### Backup Existing Files
+- If `.geminiignore` exists, create backup as `.geminiignore.backup`
+- Include timestamp in backup filename
+
+## Integration Points
+
+### Workflow Commands
+- **After `/workflow:plan`**: Suggest running gemini-ignore for better analysis
+- **Before analysis**: Recommend updating ignore patterns for cleaner results
+
+### CLI Tool Integration
+- Automatically update when new technologies detected
+- Integrate with `intelligent-tools-strategy.md` recommendations
+
+## Usage Examples
+
+### Basic Project Setup
+```bash
+# New project - initialize Gemini configuration
+/workflow:gemini-init
+
+# Preview what would be generated
+/workflow:gemini-init --preview
+
+# Generate in subdirectory
+/workflow:gemini-init --output=.config/
+```
+
+### Technology Migration
+```bash
+# After adding new tech stack (e.g., Docker)
+/workflow:gemini-init  # Regenerates both config and ignore files with new rules
+
+# Check what changed
+/workflow:gemini-init --preview  # Compare with existing configuration
+```
+
+## Key Benefits
+
+- **Automatic Detection**: No manual configuration needed
+- **Technology Aware**: Rules adapted to actual project stack
+- **Maintainable**: Clear sections for easy customization
+- **Consistent**: Follows gitignore syntax standards
+- **Safe**: Creates backups of existing files
