Automating PR Workflows with Claude Task Master

Automating PR Workflows with Claude Task Master

Claude Task Master (CLI claudetm) is an autonomous task orchestration system built on the Claude Agent SDK. It keeps Claude working until a goal is achieved, handling planning, execution, pull-request creation, CI failures, review comments, and final merge. This article explains how the tool works, its core features, and how you can integrate it into existing development pipelines.

Core Workflow

The workflow consists of four main phases: planning, working, PR lifecycle, and verification. When you start a task with claudetm start "Add user authentication with tests", the CLI reads the codebase, creates a task list, and defines success criteria. It then makes changes, runs tests, commits, and pushes each change as a separate pull request. The PR lifecycle waits for CI checks, fixes any failures, addresses review comments, and merges automatically when approved. Finally, verification runs lint and tests to confirm all criteria are met before marking the task as complete.

State Persistence and Resilience

A key advantage is state persistence. The CLI stores its progress in a mailbox system, allowing it to survive interruptions such as a server restart or a lost network connection. When the process resumes, it picks up exactly where it left off, ensuring no work is lost.

Multi-Instance Coordination

Claude Task Master supports multiple instances running in parallel via isolated profiles. Profiles can be oauth based, using separate Claude Code configuration directories, or api-key based, injecting ANTHROPIC_API_KEY and ANTHROPIC_BASE_URL. This isolation lets teams run several Claude subscriptions without credential conflicts.

Extensibility Through API and Webhooks

The tool exposes a REST API, MCP server, and HMAC-signed webhooks that mirror the CLI lifecycle. External systems can dispatch new tasks, monitor progress, and react to events such as PR creation or CI failure. This makes it easy to embed Claude Task Master in dashboards, CI pipelines, or custom bots.

Quick Start 

# Install via uv, pip, or Docker
uv tool install claude-task-master

# Authenticate with Claude
claude login

# Run a task
cd your-project
claudetm start "Add user authentication with tests"
Enter fullscreen mode Exit fullscreen mode

The CLI works with Python >= 3.10, Ruby on Rails, JavaScript, and other languages supported by Claude Code.

When to Use Claude Task Master

  • Teams already using Claude Code that want end-to-end PR automation.
  • Projects with well-scoped goals that can be verified against explicit success criteria.
  • Environments that run multiple Claude subscriptions and need isolation.

Conclusion

Claude Task Master provides a hands-off, PR-based development experience that survives interruptions and scales across multiple subscriptions. By exposing a REST API and webhook hooks, it enables building higher-level agentic workflows on top of a reliable foundation. The tool is open source under the MIT license and can be installed via PyPI or Docker.
