taskmaster is a cursor rule for Cursor from radiantlogicinc/fastworkflow. It costs 8,043 tokens per session, scanned B, a copy of taskmaster, Apache-2.0.

A reference for Taskmaster, a project-planning tool available through MCP integrations and command-line commands. MCP is a standard way for connected tools to exchange structured requests and results.

In plain words
What is it for?

Why use it?
It puts the tool names, setup commands, options, and fallback commands in one place, reducing guesswork when managing project tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

taskmaster scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Taskmaster Tool & Command Reference

This document provides a detailed reference for interacting with Taskmaster, covering both the recommended MCP tools, suitable for integrations like Cursor, 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.


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 and taskmaster. 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 Cursor. 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.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
