# Meta-Development Script

This folder contains a **meta-development script** (`dev.js`) and related utilities that manage tasks for an AI-driven or traditional software development workflow. The script revolves around a `tasks.json` file, which holds an up-to-date list of development tasks.

## Overview

In an AI-driven development process—particularly with tools like [Cursor](https://www.cursor.so/)—it's beneficial to have a **single source of truth** for tasks. This script allows you to:

1. **Parse** a PRD or requirements document (`.txt`) to initialize a set of tasks (`tasks.json`).
2. **List** all existing tasks (IDs, statuses, titles).
3. **Update** tasks to accommodate new prompts or architecture changes (useful if you discover "implementation drift").
4. **Generate** individual task files (e.g., `task_001.txt`) for easy reference or to feed into an AI coding workflow.
5. **Set task status**—mark tasks as `done`, `pending`, or `deferred` based on progress.
6. **Expand** tasks with subtasks—break down complex tasks into smaller, more manageable subtasks.
7. **Research-backed subtask generation**—use Perplexity AI to generate more informed and contextually relevant subtasks.
8. **Clear subtasks**—remove subtasks from specified tasks to allow regeneration or restructuring.
9. **Show task details**—display detailed information about a specific task and its subtasks.

## Configuration (Updated)

Task Master configuration is now managed through two primary methods:

1.  **`.taskmaster/config.json` File (Project Root - Primary)**

    - Stores AI model selections (`main`, `research`, `fallback`), model parameters (`maxTokens`, `temperature`), `logLevel`, `defaultSubtasks`, `defaultPriority`, `projectName`, etc.
    - Managed using the `task-master models --setup` command or the `models` MCP tool.
    - This is the main configuration file for most settings.

2.  **Environment Variables (`.env` File - API Keys Only)**
    - Used **only** for sensitive **API Keys** (e.g., `ANTHROPIC_API_KEY`, `PERPLEXITY_API_KEY`).
    - Create a `.env` file in your project root for CLI usage.
    - See `assets/env.example` for required key names.

**Important:** Settings like `MODEL`, `MAX_TOKENS`, `TEMPERATURE`, `TASKMASTER_LOG_LEVEL`, etc., are **no longer set via `.env`**. Use `task-master models --setup` instead.

## How It Works

1. **`tasks.json`**:

   - A JSON file at the project root containing an array of tasks (each with `id`, `title`, `description`, `status`, etc.).
   - The `meta` field can store additional info like the project's name, version, or reference to the PRD.
   - Tasks can have `subtasks` for more detailed implementation steps.
   - Dependencies are displayed with status indicators (✅ for completed, ⏱️ for pending) to easily track progress.

2. **CLI Commands**
   You can run the commands via:

   ```bash
   # If installed globally
   task-master [command] [options]

   # If using locally within the project
   node scripts/dev.js [command] [options]
   ```

   Available commands:

   - `init`: Initialize a new project
   - `parse-prd`: Generate tasks from a PRD document
   - `list`: Display all tasks with their status
   - `update`: Update tasks based on new information
   - `generate`: Create individual task files
   - `set-status`: Change a task's status
   - `expand`: Add subtasks to a task or all tasks
   - `clear-subtasks`: Remove subtasks from specified tasks
   - `next`: Determine the next task to work on based on dependencies
   - `show`: Display detailed information about a specific task
   - `analyze-complexity`: Analyze task complexity and generate recommendations
   - `complexity-report`: Display the complexity analysis in a readable format
   - `add-dependency`: Add a dependency between tasks
   - `remove-dependency`: Remove a dependency from a task
   - `validate-dependencies`: Check for invalid dependencies
   - `fix-dependencies`: Fix invalid dependencies automatically
   - `add-task`: Add a new task using AI

   Run `task-master --help` or `node scripts/dev.js --help` to see detailed usage information.

## Listing Tasks

The `list` command allows you to view all tasks and their status:

```bash
# List all tasks
task-master list

# List tasks with a specific status
task-master list --status=pending

# List tasks and include their subtasks
task-master list --with-subtasks

# List tasks with a specific status and include their subtasks
task-master list --status=pending --with-subtasks
```

## Updating Tasks

The `update` command allows you to update tasks based on new information or implementation changes:

```bash
# Update tasks starting from ID 4 with a new prompt
task-master update --from=4 --prompt="Refactor tasks from ID 4 onward to use Express instead of Fastify"

# Update all tasks (default from=1)
task-master update --prompt="Add authentication to all relevant tasks"

# Specify a different tasks file
task-master update --file=custom-tasks.json --from=5 --prompt="Change database from MongoDB to PostgreSQL"
```

Notes:

- The `--prompt` parameter is required and should explain the changes or new context
- Only tasks that aren't marked as 'done' will be updated
- Tasks with ID >= the specified --from value will be updated

## Setting Task Status

The `set-status` command allows you to change a task's status:

```bash
# Mark a task as done
task-master set-status --id=3 --status=done

# Mark a task as pending
task-master set-status --id=4 --status=pending

# Mark a specific subtask as done
task-master set-status --id=3.1 --status=done

# Mark multiple tasks at once
task-master set-status --id=1,2,3 --status=done
```

Notes:

- When marking a parent task as "done", all of its subtasks will automatically be marked as "done" as well
- Common status values are 'done', 'pending', and 'deferred', but any string is accepted
- You can specify multiple task IDs by separating them with commas
- Subtask IDs are specified using the format `parentId.subtaskId` (e.g., `3.1`)
- Dependencies are updated to show completion status (✅ for completed, ⏱️ for pending) throughout the system

## Expanding Tasks

The `expand` command allows you to break down tasks into subtasks for more detailed implementation:

```bash
# Expand a specific task with 3 subtasks (default)
task-master expand --id=3

# Expand a specific task with 5 subtasks
task-master expand --id=3 --num=5

# Expand a task with additional context
task-master expand --id=3 --prompt="Focus on security aspects"

# Expand all pending tasks that don't have subtasks
task-master expand --all

# Force regeneration of subtasks for all pending tasks
task-master expand --all --force

# Use Perplexity AI for research-backed subtask generation
task-master expand --id=3 --research

# Use Perplexity AI for research-backed generation on all pending tasks
task-master expand --all --research
```

## Clearing Subtasks

The `clear-subtasks` command allows you to remove subtasks from specified tasks:

```bash
# Clear subtasks from a specific task
task-master clear-subtasks --id=3

# Clear subtasks from multiple tasks
task-master clear-subtasks --id=1,2,3

# Clear subtasks from all tasks
task-master clear-subtasks --all
```

Notes:

- After clearing subtasks, task files are automatically regenerated
- This is useful when you want to regenerate subtasks with a different approach
- Can be combined with the `expand` command to immediately generate new subtasks
- Works with both parent tasks and individual subtasks

## AI Integration (Updated)

- The script now uses a unified AI service layer (`ai-services-unified.js`).
- Model selection (e.g., Claude vs. Perplexity for `--research`) is determined by the configuration in `.taskmaster/config.json` based on the requested `role` (`main` or `research`).
- API keys are automatically resolved from your `.env` file (for CLI) or MCP session environment.
- To use the research capabilities (e.g., `expand --research`), ensure you have:
  1.  Configured a model for the `research` role using `task-master models --setup` (Perplexity models are recommended).
  2.  Added the corresponding API key (e.g., `PERPLEXITY_API_KEY`) to your `.env` file.

## Logging

The script supports different logging levels controlled by the `TASKMASTER_LOG_LEVEL` environment variable:

- `debug`: Detailed information, typically useful for troubleshooting
- `info`: Confirmation that things are working as expected (default)
- `warn`: Warning messages that don't prevent execution
- `error`: Error messages that might prevent execution

When `DEBUG=true` is set, debug logs are also written to a `dev-debug.log` file in the project root.

## Managing Task Dependencies

The `add-dependency` and `remove-dependency` commands allow you to manage task dependencies:

```bash
# Add a dependency to a task
task-master add-dependency --id=<id> --depends-on=<id>

# Remove a dependency from a task
task-master remove-dependency --id=<id> --depends-on=<id>
```

These commands:

1. **Allow precise dependency management**:

   - Add dependencies between tasks with automatic validation
   - Remove dependencies when they're no longer needed
   - Update task files automatically after changes

2. **Include validation checks**:

   - Prevent circular dependencies (a task depending on itself)
   - Prevent duplicate dependencies
   - Verify that both tasks exist before adding/removing dependencies
   - Check if dependencies exist before attempting to remove them

3. **Provide clear feedback**:

   - Success messages confirm when dependencies are added/removed
   - Error messages explain why operations failed (if applicable)

4. **Automatically update task files**:
   - Regenerates task files to reflect dependency changes
   - Ensures tasks and their files stay synchronized

## Dependency Validation and Fixing

The script provides two specialized commands to ensure task dependencies remain valid and properly maintained:

### Validating Dependencies

The `validate-dependencies` command allows you to check for invalid dependencies without making changes:

```bash
# Check for invalid dependencies in tasks.json
task-master validate-dependencies

# Specify a different tasks file
task-master validate-dependencies --file=custom-tasks.json
```

This command:

- Scans all tasks and subtasks for non-existent dependencies
- Identifies potential self-dependencies (tasks referencing themselves)
- Reports all found issues without modifying files
- Provides a comprehensive summary of dependency state
- Gives detailed statistics on task dependencies

Use this command to audit your task structure before applying fixes.

### Fixing Dependencies

The `fix-dependencies` command proactively finds and fixes all invalid dependencies:

```bash
# Find and fix all invalid dependencies
task-master fix-dependencies

# Specify a different tasks file
task-master fix-dependencies --file=custom-tasks.json
```

This command:

1. **Validates all dependencies** across tasks and subtasks
2. **Automatically removes**:
   - References to non-existent tasks and subtasks
   - Self-dependencies (tasks depending on themselves)
3. **Fixes issues in both**:
   - The tasks.json data structure
   - Individual task files during regeneration
4. **Provides a detailed report**:
   - Types of issues fixed (non-existent vs. self-dependencies)
   - Number of tasks affected (tasks vs. subtasks)
   - Where fixes were applied (tasks.json vs. task files)
   - List of all individual fixes made

This is especially useful when tasks have been deleted or IDs have changed, potentially breaking dependency chains.

## Analyzing Task Complexity

The `analyze-complexity` command allows you to automatically assess task complexity and generate expansion recommendations:

```bash
# Analyze all tasks and generate expansion recommendations
task-master analyze-complexity

# Specify a custom output file
task-master analyze-complexity --output=custom-report.json

# Override the model used for analysis
task-master analyze-complexity --model=claude-3-opus-20240229

# Set a custom complexity threshold (1-10)
task-master analyze-complexity --threshold=6

# Use Perplexity AI for research-backed complexity analysis
task-master analyze-complexity --research
```

Notes:

- The command uses Claude to analyze each task's complexity (or Perplexity with --research flag)
- Tasks are scored on a scale of 1-10
- Each task receives a recommended number of subtasks based on DEFAULT_SUBTASKS configuration
- The default output path is `scripts/task-complexity-report.json`
- Each task in the analysis includes a ready-to-use `expansionCommand` that can be copied directly to the terminal or executed programmatically
- Tasks with complexity scores below the threshold (default: 5) may not need expansion
- The research flag provides more contextual and informed complexity assessments

### Integration with Expand Command

The `expand` command automatically checks for and uses complexity analysis if available:

```bash
# Expand a task, using complexity report recommendations if available
task-master expand --id=8

# Expand all tasks, prioritizing by complexity score if a report exists
task-master expand --all

# Override recommendations with explicit values
task-master expand --id=8 --num=5 --prompt="Custom prompt"
```

When a complexity report exists:

- The `expand` command will use the recommended subtask count from the report (unless overridden)
- It will use the tailored expansion prompt from the report (unless a custom prompt is provided)
- When using `--all`, tasks are sorted by complexity score (highest first)
- The `--research` flag is preserved from the complexity analysis to expansion

The output report structure is:

```json
{
  "meta": {
    "generatedAt": "2023-06-15T12:34:56.789Z",
    "tasksAnalyzed": 20,
    "thresholdScore": 5,
    "projectName": "Your Project Name",
    "usedResearch": true
  },
  "complexityAnalysis": [
    {
      "taskId": 8,
      "taskTitle": "Develop Implementation Drift Handling",
      "complexityScore": 9.5,
      "recommendedSubtasks": 6,
      "expansionPrompt": "Create subtasks that handle detecting...",
      "reasoning": "This task requires sophisticated logic...",
      "expansionCommand": "task-master expand --id=8 --num=6 --prompt=\"Create subtasks...\" --research"
    }
    // More tasks sorted by complexity score (highest first)
  ]
}
```

## Finding the Next Task

The `next` command helps you determine which task to work on next based on dependencies and status:

```bash
# Show the next task to work on
task-master next

# Specify a different tasks file
task-master next --file=custom-tasks.json
```

This command:

1. Identifies all **eligible tasks** - pending or in-progress tasks whose dependencies are all satisfied (marked as done)
2. **Prioritizes** these eligible tasks by:
   - Priority level (high > medium > low)
   - Number of dependencies (fewer dependencies first)
   - Task ID (lower ID first)
3. **Displays** comprehensive information about the selected task:
   - Basic task details (ID, title, priority, dependencies)
   - Detailed description and implementation details
   - Subtasks if they exist
4. Provides **contextual suggested actions**:
   - Command to mark the task as in-progress
   - Command to mark the task as done when completed
   - Commands for working with subtasks (update status or expand)

This feature ensures you're always working on the most appropriate task based on your project's current state and dependency structure.

## Showing Task Details

The `show` command allows you to view detailed information about a specific task:

```bash
# Show details for a specific task
task-master show 1

# Alternative syntax with --id option
task-master show --id=1

# Show details for a subtask
task-master show --id=1.2

# Specify a different tasks file
task-master show 3 --file=custom-tasks.json
```

This command:

1. **Displays comprehensive information** about the specified task:
   - Basic task details (ID, title, priority, dependencies, status)
   - Full description and implementation details
   - Test strategy information
   - Subtasks if they exist
2. **Handles both regular tasks and subtasks**:
   - For regular tasks, shows all subtasks and their status
   - For subtasks, shows the parent task relationship
3. **Provides contextual suggested actions**:
   - Commands to update the task status
   - Commands for working with subtasks
   - For subtasks, provides a link to view the parent task

This command is particularly useful when you need to examine a specific task in detail before implementing it or when you want to check the status and details of a particular task.
