gstack

gstack is a skill library for AI coding agents that simulates a full virtual engineering team. Originally created by Y Combinator CEO Garry Tan, it ships 23 specialist slash commands plus eight power-tool commands covering every stage of a development sprint: think, plan, build, review, test, ship, and reflect. **What it includes** - Planning and strategy: `/office-hours`, `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review`, `/autoplan` - Design: `/design-consultation`, `/design-review`, `/design-shotgun`, `/design-html` - Code review and debugging: `/review`, `/investigate` - QA and testing: `/qa`, `/qa-only` - Developer experience: `/devex-review` - Security: `/cso` (OWASP Top 10 + STRIDE) - Release and deployment: `/ship`, `/land-and-deploy`, `/canary`, `/benchmark` - Documentation: `/document-release`, `/document-generate` - Browsing and scraping: `/browse`, `/scrape`, `/setup-browser-cookies` - Utilities: `/make-pdf`, `/diagram`, `/spec`, `/learn`, `/retro`, `/pair-agent` **Agent support** While built for Claude Code, gstack auto-detects and supports ten coding agents out of the box: OpenAI Codex CLI, OpenCode, Cursor, Factory Droid, Kiro, Slate, OpenClaw, Hermes, and GBrain. An instruction-only digest is available for any agent that reads AGENTS.md files. **Team mode** A team-mode setup lets repositories require or recommend gstack for all AI-assisted work. Sessions check for updates automatically (once per hour, failure-safe), and no vendored files are committed to user repos. **Installation** Run the provided one-liner from within Claude Code, or clone and run `./setup` from the command line. macOS users are encouraged to use the Aside browser for authenticated web testing; the fallback is a bundled Chromium instance with anti-bot stealth.
