Run Claude Code Like a Full Engineering Team With GStack by Garry Tan

23 specialist skills that turn Claude Code into an engineering team

Who This Is For

Founders and small teams who want Claude Code to run like an engineering team

This is for founders, solo developers, and small teams who want Claude Code to function as a structured engineering team — moving a task through planning, building, QA, shipping, and learning instead of handling everything ad hoc.

You'll need the Claude Code CLI installed, since GStack's 23 skills run as slash commands in your terminal. Most of the planning and review skills need no coding knowledge, but a few — like iOS QA and canary deploy — are developer-facing and assume some technical background.

One correction worth knowing: GStack's /skillify command converts a browser scraping session into a reusable script with tests. It doesn't generally "extract your patterns" from anything you do — it's specific to scraping workflows. The real compounding effect comes from the /learn and /retro commands, which persist decisions across sessions.

By the end, you'll have GStack running in Claude Code, taking a task from CEO-level product review through engineering, QA, and deployment, with every decision recorded so future sessions build on what came before.

Starter Prompt

Set up GStack in Claude Code. I'm a founder/solo developer working on [describe your app/project]. Install GStack's 23 specialist skills so Claude Code can run like a full engineering team, handling planning, building, QA, and shipping instead of ad hoc requests. Once installed, walk me through: 1) which skills apply to my current task, 2) how to trigger them as slash commands, and 3) how /skillify can turn a repeated browser-scraping workflow of mine into a reusable, tested script. Confirm the Claude Code CLI is installed first, and flag any steps that need developer-level review (like QA or canary deploy skills) versus steps a non-technical founder can run solo.
