What gstack-workflow-assistant does

The skill provides separate workflows for product and engineering planning, code review, shipping a branch, QA, and retrospectives. For example, /plan-eng-review focuses on architecture, while /review checks code changes for issues such as race conditions and missing error handling.

Browser workflows use /browse, /qa, and /setup-browser-cookies to explore app pages, test user flows, and work with authenticated sessions. Git is needed for workflows involving branches and history. Browser automation requires Bun v1.0+ and macOS or Linux, so that part will not run on other operating systems.

Install the skill with the command for your platform. In Claude Code, you can add its command list to CLAUDE.md; /ship handles branch release steps and pull request creation.

What it helps with

  • review a product idea before implementation
  • map architecture and failure cases
  • inspect code changes for production issues
  • test app pages through browser workflows
  • ship a branch and open a pull request

Example prompts for the agent

  • Review the architecture for this feature with /plan-eng-review.
  • Check the current changes with /review.
  • Explore the app page in a browser with /browse https://myapp.com.
