+    As AI-powered coding assistants become essential development tools, managing file access permissions efficiently is crucial. If you're using Gemini CLI and finding yourself repeatedly approving the same directory prompts, this guide will help you configure trusted directories and reclaim your valuable development time.
+  </p>
+</div>
+
+The Gemini CLI is Google's powerful command-line interface for interacting with Gemini AI models directly from your terminal. Whether you're building <Link to="/cloud-native-management/meshery">cloud native applications</Link>, automating infrastructure tasks, or leveraging AI for code generation, the Gemini CLI can significantly enhance your productivity—but only if it's properly configured.
+
+## The Trust Prompt Challenge
+
+When you first run Gemini CLI in a new directory, you'll encounter trust dialogs that ask for permission to access files in that location. While this security feature protects your sensitive data, it can become a productivity bottleneck when working across multiple projects or frequently switching between directories.
+
+**The problem:** Every time you navigate to a new folder, you're interrupted by permission requests. For platform engineers and DevOps practitioners managing multiple repositories, microservices, or infrastructure-as-code projects, these interruptions add up quickly.
+
+**The solution:** Configure trusted directories once, and work uninterrupted across all your projects.
+
+## Three Ways to Configure Trusted Directories
+
+Gemini CLI offers three flexible approaches to managing trusted directories, each suited to different workflows and preferences. Let's explore each method in detail.
+
+### 1. Interactive Prompts: The Quick Start Method
+
+The most straightforward way to configure trust settings is through the interactive prompts that appear when you first use Gemini CLI in a new directory.
+
+#### How It Works
+
+When running Gemini CLI in an untrusted folder, you'll see a dialog with two primary options:
+
+**Trust Folder**: This option trusts only the current directory. Choose this when:
+- You're working in a single, isolated project
+- The directory contains sensitive information and you want granular control
+- You want to test Gemini CLI functionality in a specific location
+
+**Trust Parent Folder**: This option trusts the current folder and all its subdirectories. This is ideal when:
+- You're managing a monorepo with multiple projects
+- Your workspace contains related microservices
+- You want to streamline trust management across a project hierarchy
+
+<Blockquote
+  quote="Trusting parent folders intelligently reduces configuration overhead—one decision covers an entire project tree, letting you focus on building rather than managing permissions."
+  person="Platform Engineering Best Practice"
+  title="Layer5 Community"
+/>
+
+#### Modifying Trust Settings
+
+Already working in a directory but want to change its trust level? No problem. Simply run:
+
+```bash
+/permissions
+```
+
+This command brings up the interactive dialog from within your current directory, allowing you to adjust trust settings on the fly without leaving your workflow.
+
+### 2. Command-Line Multi-Directory Support
+
+For engineers who prefer command-line efficiency or need to work across multiple unrelated directories simultaneously, Gemini CLI provides powerful command-line options for directory management.
+
+#### Starting a Session with Multiple Directories
+
+To give Gemini CLI access to multiple directories from the start, use the `--include-directories` flag:
+
+```bash
+gemini --include-directories path/to/dir1,path/to/dir2,path/to/dir3
+```
+
+**Key points:**
+- Paths can be **absolute** (e.g., `/home/user/projects/api`) or **relative** (e.g., `../frontend`)
+- Separate multiple paths with commas (no spaces)
+- This is particularly useful for cross-project workflows
+
+**Example use case:** A platform engineer working on a <Link to="/cloud-native-management/meshery">Meshery</Link> deployment might need access to:
+- The main application repository
+- A shared Kubernetes manifests directory
+- Infrastructure-as-code configurations
+- Documentation repository
+
+```bash
+gemini --include-directories ~/projects/meshery-app,~/k8s/manifests,~/terraform/prod,~/docs/api
+```
+
+#### Adding Directories During an Active Session
+
+Already in a Gemini CLI session and need to add another directory? Use the `/directory add` command:
+
+```bash
+/directory add <path>
+```
+
+You can even add multiple directories at once by separating them with commas:
+
+```bash
+/directory add ~/new-project,~/shared-utils,~/config
+```
+
+The alias `/dir` works identically for convenience:
+
+```bash
+/dir add ~/another-project
+```
+
+#### Viewing Active Directories
+
+To see all directories currently accessible in your session:
+
+```bash
+/directory show
+```
+
+Or using the shorter alias:
+
+```bash
+/dir show
+```
+
+This command displays a complete list of all trusted directories for the current session, helping you verify your configuration and understand the scope of file access.

+  <h3>💡 Pro Tip for DevOps Teams</h3>
+  <p>When working with <Link to="/cloud-native-management/kanvas">infrastructure design tools like Kanvas</Link>, organize your Kubernetes manifests, Helm charts, and configuration files in a parent directory. Trust that parent folder once, and Gemini CLI will have seamless access to your entire infrastructure-as-code setup.</p>
+</div>
+
+### 3. Manual Configuration: The Power User Approach
+
+For advanced users, automation enthusiasts, or those managing multiple machines, manually editing the trusted folders configuration file provides the ultimate control and reproducibility.
+
+#### Understanding the Configuration File
+
+Trusted folder rules are stored in a JSON file located at:
+
+```bash
+~/.gemini/trustedFolders.json
+```
+
+This file resides in your home directory's `.gemini` folder and persists across CLI sessions.
+
+#### File Structure and Format
+
+The `trustedFolders.json` file uses a straightforward JSON structure. Here's an example:
+
+```json
+{
+  "trustedFolders": [
+    "/home/username/projects/meshery",
+    "/home/username/kubernetes/clusters",
+    "/home/username/terraform/infrastructure",
+    "/opt/shared/configs"
+  ]
+}
+```
+
+#### Editing the Configuration File
+
+You can edit this file directly using any text editor:
+
+```bash
+nano ~/.gemini/trustedFolders.json
+```
+
+Or with your preferred editor:
+
+```bash
+vim ~/.gemini/trustedFolders.json
+code ~/.gemini/trustedFolders.json  # VS Code
+```
+
+#### Adding and Removing Paths
+
+**To add a new trusted directory:**
+1. Open the file in your editor
+2. Add the full path to the `trustedFolders` array
+3. Ensure proper JSON formatting (commas between entries, quotes around paths)
+4. Save the file
+
+**To remove a trusted directory:**
+1. Open the file
+2. Delete the line containing the path (and any trailing comma if it's the last entry)
+3. Save the file
+
+**Example workflow:**
+
+```bash
+# Backup your current configuration
+cp ~/.gemini/trustedFolders.json ~/.gemini/trustedFolders.json.backup
+
+# Edit the configuration
+nano ~/.gemini/trustedFolders.json
+
+# Verify JSON syntax (optional but recommended)
+python3 -c "import json; json.load(open('$HOME/.gemini/trustedFolders.json'))"
+```
+
+<Blockquote
+  quote="Manual configuration enables version control and automation—commit your trustedFolders.json to your dotfiles repository and deploy consistent Gemini CLI settings across all your development machines."
+  person="DevOps Automation Strategy"
+  title="Infrastructure as Code"
+/>
+
+#### Applying Changes
+
+After editing the file, changes take effect when you:
+- Restart your current Gemini CLI session
+- Start a new Gemini CLI session
+
+**Important:** Changes to `trustedFolders.json` do **not** apply to already-running CLI sessions. Simply exit and restart the CLI to pick up your modifications.
+
+## Best Practices for Trusted Directories
+
+### Security Considerations
+
+While configuring trusted directories improves workflow efficiency, it's essential to maintain security best practices:
+
+1. **Be selective**: Only trust directories you actively use with Gemini CLI
+2. **Avoid overly broad permissions**: Trusting your entire home directory (`~`) exposes all files—use specific project directories instead
+3. **Regular audits**: Periodically review `~/.gemini/trustedFolders.json` and remove directories for completed or archived projects
+4. **Sensitive data**: Keep directories containing secrets, credentials, or PII (Personally Identifiable Information) untrusted unless absolutely necessary
+
+### Organizational Strategies
+
+**For Solo Developers:**
+- Trust parent folders for active projects
+- Use specific folder trust for exploratory or temporary work
+- Maintain a clean project directory structure to minimize trust scope
+
+**For Teams and Organizations:**
+- Standardize project directory layouts across the team
+- Document trusted directory policies in team onboarding materials
+- Consider using absolute paths in shared documentation for consistency
+- Leverage version-controlled dotfiles to distribute configuration
+
+**For Multi-Environment Workflows:**
+- Separate development, staging, and production directories
+- Apply stricter trust policies to production-related directories
+- Use environment-specific parent folders (e.g., `~/dev/`, `~/staging/`, `~/prod/`)
+
+## Integration with Cloud Native Workflows
+
+Gemini CLI's trusted directories feature becomes even more powerful when integrated into cloud native development workflows. Here are practical examples:
+
+### Kubernetes and Container Development
+
+When working with <Link to="/cloud-native-management/meshery">Kubernetes orchestration</Link>, trust your entire K8s workspace:
+
+```bash
+# Trust your Kubernetes project root
+/permissions  # Select "Trust parent folder" for ~/projects/k8s-apps/
+
+# Or via command line
+gemini --include-directories ~/projects/k8s-apps,~/helm-charts,~/.kube/configs
+```
+
+This configuration allows Gemini CLI to assist with:
+- Generating and validating YAML manifests
+- Troubleshooting deployment configurations
+- Analyzing pod logs and resource definitions
+- Creating Helm chart templates
+
+### Infrastructure as Code
+
+For infrastructure automation with tools like Terraform, Pulumi, or Ansible:
+
+```bash
+gemini --include-directories ~/infrastructure/terraform,~/infrastructure/ansible-playbooks,~/infrastructure/scripts
+```
+
+Benefits include:
+- AI-assisted infrastructure code generation
+- Configuration validation and best practice suggestions
+- Documentation generation from IaC definitions
+- Troubleshooting infrastructure drift
+
+### Multi-Repository Projects
+
+Modern cloud native applications often span multiple repositories. Configure Gemini CLI to work seamlessly across your architecture:
+
+```bash
+# Add all microservice repositories
+/dir add ~/services/api-gateway
+/dir add ~/services/auth-service
+/dir add ~/services/data-processing
+/dir add ~/services/notification-service
+/dir add ~/shared/common-libraries
+```
+
+## Troubleshooting Common Issues
+
+### Permission Prompts Still Appearing
+
+**Problem:** You've configured trusted directories, but prompts still appear.
+
+**Solutions:**
+1. Verify the exact path in `~/.gemini/trustedFolders.json` matches your working directory
+2. Check for typos in paths (case-sensitive on Unix-like systems)
+3. Ensure you've restarted the Gemini CLI session after configuration changes
+4. Confirm you're working in a subdirectory of a trusted parent folder
+
+### JSON Syntax Errors
+
+**Problem:** Configuration changes aren't working, or Gemini CLI reports errors.
+
+**Solutions:**
+1. Validate JSON syntax: `python3 -c "import json; json.load(open('$HOME/.gemini/trustedFolders.json'))"`
+2. Check for missing commas between array entries
+3. Ensure all paths are enclosed in double quotes
+4. Verify the closing bracket and brace are present
+
+### Symbolic Links and Mount Points
+
+**Problem:** Trusted directories aren't recognized when accessed via symbolic links.
+
+**Solutions:**
+1. Add both the real path and symlink path to trusted folders
+2. Use absolute paths to avoid resolution issues
+3. Check with `realpath <directory>` to find the canonical path
+
