How to pressure-test a product idea with /office-hours before you build with Gstack

Describe what you want to build and let Gstack push back on the framing and write a design doc.

Short answer: Open Claude Code and install Gstack: git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup; then run /office-hours and describe what you are building with specific examples of the pain; Agree, disagree or adjust as it challenges your premises and proposes approaches. All steps.

Who it is forA technical founder about to spend a week building the wrong version of an idea.

The problemIt is easy to build exactly what you described instead of what users need, and nobody challenges the premise.

The outcomeA design doc with challenged premises and implementation approaches that the other Gstack skills read automatically.

What you need first

  • Claude Code (full tier) or another supported agent
  • Git
  • Bun v1.4.2+ (setup refuses older than 1.3.3)
  • Node.js on Windows and for team mode
  • Optional on macOS 15+: the Aside browser for browser skills

Steps

  1. Open Claude Code and install Gstack: git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup
  2. Run /office-hours and describe what you are building with specific examples of the pain
  3. Agree, disagree or adjust as it challenges your premises and proposes approaches
  4. Run /plan-ceo-review and /plan-eng-review to challenge scope and lock the architecture
  5. Approve the plan and let Claude build from the design doc

Prompt for your agent

Install garrytan/gstack and run /office-hours on this idea: <idea>. Push back on my framing, write the design doc, then run /plan-ceo-review and /plan-eng-review and summarize what changed before writing any code.

Caveat.
