gstack is a collection of Markdown-based slash-command skills for Claude Code and other coding agents. Each skill takes a specialist role: product/CEO review (/office-hours), engineering manager and plan review (/autoplan), designer, code reviewer (/review), QA lead (/qa), security officer (/cso, OWASP and STRIDE audits), and release engineer (/ship). It was created by Garry Tan, President and CEO of Y Combinator, and the repository dates from March 2026.\n\nThe skills follow a sprint-style workflow: think, plan, build, review, test, ship. /office-hours challenges the product framing and writes a design doc that other skills read. /review looks for bugs that pass CI, and /qa opens a real browser against a staging URL or an isolated local API, CLI, job or webhook to reproduce and fix bugs. /ship runs tests, review and opens the PR.\n\nInstallation is done by cloning the repo into ~/.claude/skills/gstack and running ./setup. This requires Claude Code, Git and Bun, plus Node.js on Windows. A team mode lets shared repos pick up updates automatically, and installs follow a stable release channel by default. It works on macOS, Windows 11 (Git Bash or WSL) and Linux. The Aside browser is recommended on macOS, with a bundled browser used elsewhere. It is MIT licensed with no premium tier, but it relies on an underlying coding agent such as Claude Code, which has its own pricing.
