# Taskmaster Tool & Command Reference

This document provides a detailed reference for interacting with Taskmaster, covering both the recommended MCP tools, suitable for integrations like VS Code, and the corresponding `task-master` CLI commands, designed for direct user interaction or fallback.

**Note:** For interacting with Taskmaster programmatically or via integrated tools, using the **MCP tools is strongly recommended** due to better performance, structured data, and error handling. The CLI commands serve as a user-friendly alternative and fallback. 

**Important:** Several MCP tools involve AI processing... The AI-powered tools include `parse_prd`, `analyze_project_complexity`, `update_subtask`, `update_task`, `update`, `expand_all`, `expand_task`, and `add_task`.

**🏷️ Tagged Task Lists System:** Task Master now supports **tagged task lists** for multi-context task management. This allows you to maintain separate, isolated lists of tasks for different features, branches, or experiments. Existing projects are seamlessly migrated to use a default "master" tag. Most commands now support a `--tag <name>` flag to specify which context to operate on. If omitted, commands use the currently active tag.

## Initialization & Setup

### 1. Initialize Project (`init`)

*   **MCP Tool:** `initialize_project`
*   **CLI Command:** `task-master init [options]`
*   **Description:** `Set up the basic Taskmaster file structure and configuration in the current directory for a new project.`
*   **Key CLI Options:**
    *   `--name <name>`: `Set the name for your project in Taskmaster's configuration.`
    *   `--description <text>`: `Provide a brief description for your project.`
    *   `--version <version>`: `Set the initial version for your project, e.g., '0.1.0'.`
    *   `-y, --yes`: `Initialize Taskmaster quickly using default settings without interactive prompts.`
*   **Usage:** Run this once at the beginning of a new project.
*   **MCP Variant Description:** `Set up the basic Taskmaster file structure and configuration in the current directory for a new project by running the 'task-master init' command.`
*   **Key MCP Parameters/Options:**
    *   `projectName`: `Set the name for your project.` (CLI: `--name <name>`)
    *   `projectDescription`: `Provide a brief description for your project.` (CLI: `--description <text>`)
    *   `projectVersion`: `Set the initial version for your project, e.g., '0.1.0'.` (CLI: `--version <version>`)
    *   `authorName`: `Author name.` (CLI: `--author <author>`)
    *   `skipInstall`: `Skip installing dependencies. Default is false.` (CLI: `--skip-install`)
    *   `addAliases`: `Add shell aliases tm, taskmaster, hamster, and ham. Default is false.` (CLI: `--aliases`)
    *   `yes`: `Skip prompts and use defaults/provided arguments. Default is false.` (CLI: `-y, --yes`)
*   **Usage:** Run this once at the beginning of a new project, typically via an integrated tool like VS Code. Operates on the current working directory of the MCP server. 
*   **Important:** Once complete, you *MUST* parse a prd in order to generate tasks. There will be no tasks files until then. The next step after initializing should be to create a PRD using the example PRD in .taskmaster/templates/example_prd.txt. 
*   **Tagging:** Use the `--tag` option to parse the PRD into a specific, non-default tag context. If the tag doesn't exist, it will be created automatically. Example: `task-master parse-prd spec.txt --tag=new-feature`.

### 2. Parse PRD (`parse_prd`)

*   **MCP Tool:** `parse_prd`
*   **CLI Command:** `task-master parse-prd [file] [options]`
*   **Description:** `Parse a Product Requirements Document, PRD, or text file with Taskmaster to automatically generate an initial set of tasks in tasks.json.`
*   **Key Parameters/Options:**
    *   `input`: `Path to your PRD or requirements text file that Taskmaster should parse for tasks.` (CLI: `[file]` positional or `-i, --input <file>`)
    *   `output`: `Specify where Taskmaster should save the generated 'tasks.json' file. Defaults to '.taskmaster/tasks/tasks.json'.` (CLI: `-o, --output <file>`)
    *   `numTasks`: `Approximate number of top-level tasks Taskmaster should aim to generate from the document.` (CLI: `-n, --num-tasks <number>`)
    *   `force`: `Use this to allow Taskmaster to overwrite an existing 'tasks.json' without asking for confirmation.` (CLI: `-f, --force`)
*   **Usage:** Useful for bootstrapping a project from an existing requirements document.
*   **Notes:** Task Master will strictly adhere to any specific requirements mentioned in the PRD, such as libraries, database schemas, frameworks, tech stacks, etc., while filling in any gaps where the PRD isn't fully specified. Tasks are designed to provide the most direct implementation path while avoiding over-engineering.
*   **Important:** This MCP tool makes AI calls and can take up to a minute to complete. Please inform users to hang tight while the operation is in progress. If the user does not have a PRD, suggest discussing their idea and then use the example PRD in `.taskmaster/templates/example_prd.txt` as a template for creating the PRD based on their idea, for use with `parse-prd`.

## AI Model Configuration

### 2. Manage Models (`models`)
*   **MCP Tool:** `models`
*   **CLI Command:** `task-master models [options]`
*   **Description:** `View the current AI model configuration or set specific models for different roles (main, research, fallback). Allows setting custom model IDs for Ollama and OpenRouter.`
*   **Key MCP Parameters/Options:**
    *   `setMain <model_id>`: `Set the primary model ID for task generation/updates.` (CLI: `--set-main <model_id>`)
    *   `setResearch <model_id>`: `Set the model ID for research-backed operations.` (CLI: `--set-research <model_id>`)
    *   `setFallback <model_id>`: `Set the model ID to use if the primary fails.` (CLI: `--set-fallback <model_id>`)
    *   `ollama <boolean>`: `Indicates the set model ID is a custom Ollama model.` (CLI: `--ollama`)
    *   `openrouter <boolean>`: `Indicates the set model ID is a custom OpenRouter model.` (CLI: `--openrouter`)
    *   `listAvailableModels <boolean>`: `If true, lists available models not currently assigned to a role.` (CLI: No direct equivalent; CLI lists available automatically)
    *   `projectRoot <string>`: `Optional. Absolute path to the project root directory.` (CLI: Determined automatically)
*   **Key CLI Options:**
    *   `--set-main <model_id>`: `Set the primary model.`
    *   `--set-research <model_id>`: `Set the research model.`
    *   `--set-fallback <model_id>`: `Set the fallback model.`
    *   `--ollama`: `Specify that the provided model ID is for Ollama (use with --set-*).`
    *   `--openrouter`: `Specify that the provided model ID is for OpenRouter (use with --set-*). Validates against OpenRouter API.`
    *   `--bedrock`: `Specify that the provided model ID is for AWS Bedrock (use with --set-*).`
    *   `--setup`: `Run interactive setup to configure models, including custom Ollama/OpenRouter IDs.`
*   **Usage (MCP):** Call without set flags to get current config. Use `setMain`, `setResearch`, or `setFallback` with a valid model ID to update the configuration. Use `listAvailableModels: true` to get a list of unassigned models. To set a custom model, provide the model ID and set `ollama: true` or `openrouter: true`.
*   **Usage (CLI):** Run without flags to view current configuration and available models. Use set flags to update specific roles. Use `--setup` for guided configuration, including custom models. To set a custom model via flags, use `--set-<role>=<model_id>` along with either `--ollama` or `--openrouter`.
*   **Notes:** Configuration is stored in `.taskmaster/config.json` in the project root. This command/tool modifies that file. Use `listAvailableModels` or `task-master models` to see internally supported models. OpenRouter custom models are validated against their live API. Ollama custom models are not validated live.
*   **API note:** API keys for selected AI providers (based on their model) need to exist in the mcp.json file to be accessible in MCP context. The API keys must be present in the local .env file for the CLI to be able to read them.
*   **Model costs:** The costs in supported models are expressed in dollars. An input/output value of 3 is $3.00. A value of 0.8 is $0.80. 
*   **Warning:** DO NOT MANUALLY EDIT THE .taskmaster/config.json FILE. Use the included commands either in the MCP or CLI format as needed. Always prioritize MCP tools when available and use the CLI as a fallback.

## Environment Variables Configuration (Updated)

Taskmaster primarily uses the **`.taskmaster/config.json`** file (in project root) for configuration (models, parameters, logging level, etc.), managed via `task-master models --setup`.

Environment variables are used **only** for sensitive API keys related to AI providers and specific overrides like the Ollama base URL:

*   **API Keys (Required for corresponding provider):**
    *   `ANTHROPIC_API_KEY`
    *   `PERPLEXITY_API_KEY`
    *   `OPENAI_API_KEY`
    *   `GOOGLE_API_KEY`
    *   `MISTRAL_API_KEY`
    *   `AZURE_OPENAI_API_KEY` (Requires `AZURE_OPENAI_ENDPOINT` too)
    *   `OPENROUTER_API_KEY`
    *   `XAI_API_KEY`
    *   `OLLAMA_API_KEY` (Requires `OLLAMA_BASE_URL` too)
*   **Endpoints (Optional/Provider Specific inside .taskmaster/config.json):**
    *   `AZURE_OPENAI_ENDPOINT`
    *   `OLLAMA_BASE_URL` (Default: `http://localhost:11434/api`)

**Set API keys** in your **`.env`** file in the project root (for CLI use) or within the `env` section of your **`.vscode/mcp.json`** file (for MCP/VS Code integration). All other settings (model choice, max tokens, temperature, log level, custom endpoints) are managed in `.taskmaster/config.json` via `task-master models` command or `models` MCP tool.

## MCP Tool Tiers

Default: `core` (7 tools). Set via `TASK_MASTER_TOOLS` env var in MCP config.

| Tier | Count | Tools |
|------|-------|-------|
| `core` | 7 | `get_tasks`, `next_task`, `get_task`, `set_task_status`, `update_subtask`, `parse_prd`, `expand_task` |
| `standard` | 14 | core + `initialize_project`, `analyze_project_complexity`, `expand_all`, `add_subtask`, `remove_task`, `add_task`, `complexity_report` |
| `all` | 44+ | standard + dependencies, tags, research, autopilot, scoping, models, rules |

**Upgrade when tool unavailable:** Edit MCP config (`.vscode/mcp.json`, `.mcp.json`, or `.vscode/mcp.json`), change `TASK_MASTER_TOOLS` from `"core"` to `"standard"` or `"all"`, restart MCP.
