feat: add non-interactive installation support (#1520)

* feat: add non-interactive installation support

Add command-line flags to support non-interactive installation for CI/CD
pipelines and automated deployments:

- --directory: Installation directory
- --modules: Comma-separated module IDs
- --tools: Tool/IDE IDs (use "none" to skip)
- --custom-content: Custom module paths
- --action: Action type for existing installations
- --user-name, --communication-language, --document-output-language, --output-folder: Core config
- -y, --yes: Accept all defaults

When flags are provided, prompts are skipped. Missing values gracefully
fall back to interactive prompts.

* fix: complete non-interactive installation support

- Fix validation checks using truthy instead of !== true
- Add skipPrompts flag to skip module config prompts with --yes
- Add getDefaultModules() for automatic module selection with --yes
- Fix IDE selection to use array check instead of length check

+title: Non-Interactive Installation
+description: Install BMAD using command-line flags for CI/CD pipelines and automated deployments
+---
+
+# Non-Interactive Installation
+
+BMAD now supports non-interactive installation through command-line flags. This is particularly useful for:
+
+- Automated deployments and CI/CD pipelines
+- Scripted installations
+- Batch installations across multiple projects
+- Quick installations with known configurations
+
+## Installation Modes
+
+### 1. Fully Interactive (Default)
+
+Run without any flags to use the traditional interactive prompts:
+
+```bash
+npx bmad-method install
+```
+
+### 2. Fully Non-Interactive
+
+Provide all required flags to skip all prompts:
+
+```bash
+npx bmad-method install \
+  --directory /path/to/project \
+  --modules bmm,bmb \
+  --tools claude-code,cursor \
+  --user-name "John Doe" \
+  --communication-language English \
+  --document-output-language English \
+  --output-folder _bmad-output
+```
+
+### 3. Semi-Interactive (Graceful Fallback)
+
+Provide some flags and let BMAD prompt for the rest:
+
+```bash
+npx bmad-method install \
+  --directory /path/to/project \
+  --modules bmm
+```
+
+In this case, BMAD will:
+- Use the provided directory and modules
+- Prompt for tool selection
+- Prompt for core configuration
+
+### 4. Quick Install with Defaults
+
+Use the `-y` or `--yes` flag to accept all defaults:
+
+```bash
+npx bmad-method install --yes
+```
+
+This will:
+- Install to the current directory
+- Skip custom content prompts
+- Use default values for all configuration
+- Use previously configured tools (or skip tool configuration if none exist)
+
+### 5. Install Without Tools
+
+To skip tool/IDE configuration entirely:
+
+**Option 1: Use --tools none**
+```bash
+npx bmad-method install --directory ~/myapp --modules bmm --tools none
+```
+
+**Option 2: Use --yes flag (if no tools were previously configured)**
+```bash
+npx bmad-method install --yes
+```
+
+**Option 3: Omit --tools and select "None" in the interactive prompt**
+```bash
+npx bmad-method install --directory ~/myapp --modules bmm
+# Then select "⚠ None - I am not installing any tools" when prompted
+```
+
+## Available Flags
+
+### Installation Options
+
+| Flag | Description | Example |
+|------|-------------|---------|
+| `--directory <path>` | Installation directory | `--directory ~/projects/myapp` |
+| `--modules <modules>` | Comma-separated module IDs | `--modules bmm,bmb` |
+| `--tools <tools>` | Comma-separated tool/IDE IDs (use "none" to skip) | `--tools claude-code,cursor` or `--tools none` |
+| `--custom-content <paths>` | Comma-separated paths to custom modules | `--custom-content ~/my-module,~/another-module` |
+| `--action <type>` | Action for existing installations | `--action quick-update` |
+
+### Core Configuration
+
+| Flag | Description | Default |
+|------|-------------|---------|
+| `--user-name <name>` | Name for agents to use | System username |
+| `--communication-language <lang>` | Agent communication language | English |
+| `--document-output-language <lang>` | Document output language | English |

+
+### Other Options
+
+| Flag | Description |
+|------|-------------|
+| `-y, --yes` | Accept all defaults and skip prompts |
+| `-d, --debug` | Enable debug output for manifest generation |
+
+## Action Types
+
+When working with existing installations, use the `--action` flag:
+
+- `install` - Fresh installation (default for new directories)
+- `update` - Modify existing installation (change modules/config)
+- `quick-update` - Refresh installation without changing configuration
+- `compile-agents` - Recompile agents with customizations only
+
+Example:
+
+```bash
+npx bmad-method install --action quick-update
+```
+
+## Module IDs
+
+Available module IDs for the `--modules` flag:
+
+### Core Modules
+- `bmm` - BMad Method Master
+- `bmb` - BMad Builder
+
+### External Modules
+Check the [BMad registry](https://github.com/bmad-code-org) for available external modules.
+
+## Tool/IDE IDs
+
+Available tool IDs for the `--tools` flag:
+
+- `claude-code` - Claude Code CLI
+- `cursor` - Cursor IDE
+- `windsurf` - Windsurf IDE
+- `vscode` - Visual Studio Code
+- `jetbrains` - JetBrains IDEs
+- And more...
+
+Run the interactive installer once to see all available tools.
+
+## Examples
+
+### Basic Installation
+
+Install BMM module with Claude Code:
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --modules bmm \
+  --tools claude-code \
+  --user-name "Development Team"
+```
+
+### Installation Without Tools
+
+Install without configuring any tools/IDEs:
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --modules bmm \
+  --tools none \
+  --user-name "Development Team"
+```
+
+### Full Installation with Multiple Modules
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --modules bmm,bmb \
+  --tools claude-code,cursor \
+  --user-name "John Doe" \
+  --communication-language English \
+  --document-output-language English \
+  --output-folder _output
+```
+
+### Update Existing Installation
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --action update \
+  --modules bmm,bmb,custom-module
+```
+
+### Quick Update (Preserve Settings)
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --action quick-update
+```
+
+### Installation with Custom Content
+
+```bash
+npx bmad-method install \
+  --directory ~/projects/myapp \
+  --modules bmm \
+  --custom-content ~/my-custom-module,~/another-module \
+  --tools claude-code
+```
+
+### CI/CD Pipeline Installation
+
+```bash
+#!/bin/bash
+# install-bmad.sh
+
+npx bmad-method install \
+  --directory "${GITHUB_WORKSPACE}" \
+  --modules bmm \
+  --tools claude-code \
+  --user-name "CI Bot" \
+  --communication-language English \
+  --document-output-language English \
+  --output-folder _bmad-output \
+  --yes
+```
+
+## Environment-Specific Installations
+
+### Development Environment
+
+```bash
+npx bmad-method install \
+  --directory . \
+  --modules bmm,bmb \
+  --tools claude-code,cursor \
+  --user-name "${USER}"
+```
+
+### Production Environment
+
+```bash
+npx bmad-method install \
+  --directory /opt/app \
+  --modules bmm \
+  --tools claude-code \
+  --user-name "Production Team" \
+  --output-folder /var/bmad-output
+```
+
+## Validation and Error Handling
+
+BMAD validates all provided flags:
+
+- **Directory**: Must be a valid path with write permissions
+- **Modules**: Will warn about invalid module IDs (but won't fail)
+- **Tools**: Will warn about invalid tool IDs (but won't fail)
+- **Custom Content**: Each path must contain a valid `module.yaml` file
+- **Action**: Must be one of: install, update, quick-update, compile-agents
+
+Invalid values will either:
+1. Show an error and exit (for critical options like directory)
+2. Show a warning and skip (for optional items like custom content)
+3. Fall back to interactive prompts (for missing required values)
+
+## Tips and Best Practices
+
+1. **Use absolute paths** for `--directory` to avoid ambiguity
+2. **Test flags locally** before using in CI/CD pipelines
+3. **Combine with `-y`** for truly unattended installations
+4. **Check module availability** by running the interactive installer once
+5. **Use `--debug`** flag if you encounter issues during installation
+6. **Skip tool configuration** with `--tools none` for server/CI environments where IDEs aren't needed
+7. **Partial flags are OK** - Omit flags and let BMAD prompt for missing values interactively
+
+## Troubleshooting
+
+### Installation fails with "Invalid directory"
+
+Check that:
+- The directory path exists or its parent exists
+- You have write permissions
+- The path is absolute or correctly relative to current directory
+
+### Module not found
+
+- Verify the module ID is correct (check available modules in interactive mode)
+- External modules may need to be available in the registry
+
+### Custom content path invalid
+
+Ensure each custom content path:
+- Points to a directory
+- Contains a `module.yaml` file in the root
+- Has a `code` field in the `module.yaml`
+
+## Feedback and Issues
+
+If you encounter any issues with non-interactive installation:
+
+1. Run with `--debug` flag for detailed output
+2. Try the interactive mode to verify the issue
+3. Report issues on GitHub: <https://github.com/bmad-code-org/BMAD-METHOD/issues>
