-Added comprehensive Ollama model validation and interactive setup support
-
-- **Interactive Setup Enhancement**: Added "Custom Ollama model" option to `task-master models --setup`, matching the existing OpenRouter functionality
-- **Live Model Validation**: When setting Ollama models, Taskmaster now validates against the local Ollama instance by querying `/api/tags` endpoint
-- **Configurable Endpoints**: Uses the `ollamaBaseUrl` from `.taskmasterconfig` (with role-specific `baseUrl` overrides supported)
-- **Robust Error Handling**: 
-  - Detects when Ollama server is not running and provides clear error messages
-  - Validates model existence and lists available alternatives when model not found
-  - Graceful fallback behavior for connection issues
-- **Full Platform Support**: Both MCP server tools and CLI commands support the new validation
-- **Improved User Experience**: Clear feedback during model validation with informative success/error messages

-This change significantly enhances the `add-task` command's intelligence. When you add a new task, Taskmaster now automatically:
-    - Analyzes your existing tasks to find those most relevant to your new task's description.
-    - Provides the AI with detailed context from these relevant tasks.
-
-This results in newly created tasks being more accurately placed within your project's dependency structure, saving you time and any need to update tasks just for dependencies, all without significantly increasing AI costs. You'll get smarter, more connected tasks right from the start.

-Add move command to enable moving tasks and subtasks within the task hierarchy. This new command supports moving standalone tasks to become subtasks, subtasks to become standalone tasks, and moving subtasks between different parents. The implementation handles circular dependencies, validation, and proper updating of parent-child relationships.
-
-**Usage:**
-- CLI command: `task-master move --from=<id> --to=<id>`
-- MCP tool: `move_task` with parameters:
-  - `from`: ID of task/subtask to move (e.g., "5" or "5.2")
-  - `to`: ID of destination (e.g., "7" or "7.3")
-  - `file` (optional): Custom path to tasks.json
-
-**Example scenarios:**
-- Move task to become subtask: `--from="5" --to="7"`
-- Move subtask to standalone task: `--from="5.2" --to="7"`
-- Move subtask to different parent: `--from="5.2" --to="7.3"`
-- Reorder subtask within same parent: `--from="5.2" --to="5.4"`
-- Move multiple tasks at once: `--from="10,11,12" --to="16,17,18"`
-- Move task to new ID: `--from="5" --to="25"` (creates a new task with ID 25)
-
-**Multiple Task Support:**
-The command supports moving multiple tasks simultaneously by providing comma-separated lists for both `--from` and `--to` parameters. The number of source and destination IDs must match. This is particularly useful for resolving merge conflicts in task files when multiple team members have created tasks on different branches.
-
-**Validation Features:**
-- Allows moving tasks to new, non-existent IDs (automatically creates placeholders)
-- Prevents moving to existing task IDs that already contain content (to avoid overwriting)
-- Validates source tasks exist before attempting to move them
-- Ensures proper parent-child relationships are maintained

This new command supports moving standalone tasks to become subtasks, subtasks to become standalone tasks, and moving subtasks between different parents. The implementation handles circular dependencies, validation, and proper updating of parent-child relationships.
+
+  **Usage:**
+
+  - CLI command: `task-master move --from=<id> --to=<id>`
+  - MCP tool: `move_task` with parameters:
+    - `from`: ID of task/subtask to move (e.g., "5" or "5.2")
+    - `to`: ID of destination (e.g., "7" or "7.3")
+    - `file` (optional): Custom path to tasks.json
+
+  **Example scenarios:**
+
+  - Move task to become subtask: `--from="5" --to="7"`
+  - Move subtask to standalone task: `--from="5.2" --to="7"`
+  - Move subtask to different parent: `--from="5.2" --to="7.3"`
+  - Reorder subtask within same parent: `--from="5.2" --to="5.4"`
+  - Move multiple tasks at once: `--from="10,11,12" --to="16,17,18"`
+  - Move task to new ID: `--from="5" --to="25"` (creates a new task with ID 25)
+
+  **Multiple Task Support:**
+  The command supports moving multiple tasks simultaneously by providing comma-separated lists for both `--from` and `--to` parameters. The number of source and destination IDs must match. This is particularly useful for resolving merge conflicts in task files when multiple team members have created tasks on different branches.
+
+  **Validation Features:**
+
+  - Allows moving tasks to new, non-existent IDs (automatically creates placeholders)
+  - Prevents moving to existing task IDs that already contain content (to avoid overwriting)
+  - Validates source tasks exist before attempting to move them
+  - Ensures proper parent-child relationships are maintained

+- **Feature branches**: `feature/description` or `fix/description`
+
+### Code Quality Standards
+
+1. **Write tests** for new functionality
+2. **Follow existing patterns** in the codebase
+3. **Add JSDoc comments** for functions
+4. **Keep functions focused** and single-purpose
+
+### Testing Requirements
+
+Your PR **must pass all CI checks**:
+
+- ✅ **Unit tests**: `npm test`
+- ✅ **Format check**: `npm run format-check`
+
+**Test your changes locally first** - this saves review time and shows you care about quality.
+
+## 📦 Changeset Guidelines
+
+We use [Changesets](https://github.com/changesets/changesets) to manage versioning and generate changelogs.
+
+### When to Create a Changeset
+
+**Always create a changeset for**:
+
+- ✅ New features
+- ✅ Bug fixes
+- ✅ Breaking changes
+- ✅ Performance improvements
+- ✅ User-facing documentation updates
+- ✅ Dependency updates that affect functionality
+
+**Skip changesets for**:
+
+- ❌ Internal documentation only
+- ❌ Test-only changes
+- ❌ Code formatting/linting
+- ❌ Development tooling that doesn't affect users
+
+### How to Create a Changeset
+
+1. **After making your changes**:
+
+   ```bash
+   npm run changeset
+   ```
+
+2. **Choose the bump type**:
+
+   - **Major**: Breaking changes
+   - **Minor**: New features
+   - **Patch**: Bug fixes, docs, performance improvements
+
+3. **Write a clear summary**:
+
+   ```
+   Add support for custom AI models in MCP configuration
+   ```
+
+4. **Commit the changeset file** with your changes:
+   ```bash
+   git add .changeset/*.md
+   git commit -m "feat: add custom AI model support"
+   ```
+
+### Changeset vs Git Commit Messages
+
+- **Changeset summary**: User-facing, goes in CHANGELOG.md
+- **Git commit**: Developer-facing, explains the technical change
+
+Example:
+
+```bash
+# Changeset summary (user-facing)
+"Add support for custom Ollama models"
+
+# Git commit message (developer-facing)
+"feat(models): implement custom Ollama model validation
+
+- Add model validation for custom Ollama endpoints
+- Update configuration schema to support custom models

+## Provider-Specific Configuration
+
+### Google Vertex AI Configuration
+
+Google Vertex AI is Google Cloud's enterprise AI platform and requires specific configuration:
+
+1. **Prerequisites**:
+   - A Google Cloud account with Vertex AI API enabled
+   - Either a Google API key with Vertex AI permissions OR a service account with appropriate roles
+   - A Google Cloud project ID
+2. **Authentication Options**:
+   - **API Key**: Set the `GOOGLE_API_KEY` environment variable
+   - **Service Account**: Set `GOOGLE_APPLICATION_CREDENTIALS` to point to your service account JSON file
+3. **Required Configuration**:
+   - Set `VERTEX_PROJECT_ID` to your Google Cloud project ID
+   - Set `VERTEX_LOCATION` to your preferred Google Cloud region (default: us-central1)
+4. **Example Setup**:
+
+   ```bash
+   # In .env file
+   GOOGLE_API_KEY=AIzaSyXXXXXXXXXXXXXXXXXXXXXXXXX
+   VERTEX_PROJECT_ID=my-gcp-project-123
+   VERTEX_LOCATION=us-central1
+   ```
+
+   Or using service account:
+
+   ```bash
+   # In .env file
+   GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json
+   VERTEX_PROJECT_ID=my-gcp-project-123
+   VERTEX_LOCATION=us-central1
+   ```
+
+5. **In .taskmasterconfig**:
+   ```json
+   "global": {
+     "vertexProjectId": "my-gcp-project-123",
+     "vertexLocation": "us-central1"
+   }

+# Task ID: 92
+# Title: Implement Project Root Environment Variable Support in MCP Configuration
+# Status: in-progress
+# Dependencies: 1, 3, 17
+# Priority: medium
+# Description: Add support for a 'TASK_MASTER_PROJECT_ROOT' environment variable in MCP configuration, allowing it to be set in both mcp.json and .env, with precedence over other methods. This will define the root directory for the MCP server and take precedence over all other project root resolution methods. The implementation should be backward compatible with existing workflows that don't use this variable.
+# Details:
+Update the MCP server configuration system to support the TASK_MASTER_PROJECT_ROOT environment variable as the standard way to specify the project root directory. This provides better namespacing and avoids conflicts with other tools that might use a generic PROJECT_ROOT variable. Implement a clear precedence order for project root resolution:
+
+1. TASK_MASTER_PROJECT_ROOT environment variable (from shell or .env file)
+2. 'projectRoot' key in mcp_config.toml or mcp.json configuration files
+3. Existing resolution logic (CLI args, current working directory, etc.)
+
+Modify the configuration loading logic to check for these sources in the specified order, ensuring backward compatibility. All MCP tools and components should use this standardized project root resolution logic. The TASK_MASTER_PROJECT_ROOT environment variable will be required because path resolution is delegated to the MCP client implementation, ensuring consistent behavior across different environments.
+
+Implementation steps:
+1. Identify all code locations where project root is determined (initialization, utility functions)
+2. Update configuration loaders to check for TASK_MASTER_PROJECT_ROOT in environment variables
+3. Add support for 'projectRoot' in configuration files as a fallback
+4. Refactor project root resolution logic to follow the new precedence rules
+5. Ensure all MCP tools and functions use the updated resolution logic
+6. Add comprehensive error handling for cases where TASK_MASTER_PROJECT_ROOT is not set or invalid
+7. Implement validation to ensure the specified directory exists and is accessible
+
+# Test Strategy:
+1. Write unit tests to verify that the config loader correctly reads project root from environment variables and configuration files with the expected precedence:
+   - Test TASK_MASTER_PROJECT_ROOT environment variable takes precedence when set
+   - Test 'projectRoot' in configuration files is used when environment variable is absent
+   - Test fallback to existing resolution logic when neither is specified
+
+2. Add integration tests to ensure that the MCP server and all tools use the correct project root:
+   - Test server startup with TASK_MASTER_PROJECT_ROOT set to various valid and invalid paths
+   - Test configuration file loading from the specified project root
+   - Test path resolution for resources relative to the project root
+
+3. Test backward compatibility:
+   - Verify existing workflows function correctly without the new variables
+   - Ensure no regression in projects not using the new configuration options
+
+4. Manual testing:
+   - Set TASK_MASTER_PROJECT_ROOT in shell environment and verify correct behavior
+   - Set TASK_MASTER_PROJECT_ROOT in .env file and verify it's properly loaded
+   - Configure 'projectRoot' in configuration files and test precedence
+   - Test with invalid or non-existent directories to verify error handling
+
+# Subtasks:
+## 92.1. Update configuration loader to check for TASK_MASTER_PROJECT_ROOT environment variable [pending]
+### Dependencies: None
+### Description: Modify the configuration loading system to check for the TASK_MASTER_PROJECT_ROOT environment variable as the primary source for project root directory. Ensure proper error handling if the variable is set but points to a non-existent or inaccessible directory.

+
+
+## 92.3. Refactor project root resolution logic with clear precedence rules [pending]
+### Dependencies: None
+### Description: Create a unified project root resolution function that follows the precedence order: 1) TASK_MASTER_PROJECT_ROOT environment variable, 2) 'projectRoot' in config files, 3) existing resolution methods. Ensure this function is used consistently throughout the codebase.
+### Details:
+
+
+## 92.4. Update all MCP tools to use the new project root resolution [pending]
+### Dependencies: None
+### Description: Identify all MCP tools and components that need to access the project root and update them to use the new resolution logic. Ensure consistent behavior across all parts of the system.
