upstack

Lightweight Claude Code (+ others) skill suite, used by the team at Upsolve AI.

Red/Green TDD workflow with 9 focused skills, minimal dependencies. Inspired by gstack and simon wilson.

Hi, I'm Serguei, CTO at Upsolve. I built Hyperauto at Palantir and I'm now working to help teams build robust, reliable data agents for their teams and customers. Like Garry, I think we're currently on the cusp of something huge in the AI coding space. But after playing around with gstack, I found its approach to be much more suited for new & ambitious greenfield projects than iterating on existing products.

At Upsolve, we are hyper focused on security, reliability, and grounding agents in real, auditable data. So our team's engineering approach requires a slightly different approach. With code being essentially free to write now, I believe we developers now need to focus on providing tightly scoped specs, project definitions, and test suites before touching a line of code. When you use upstack, it forces you to think test-first and submits code that is instantly provable and reliable. It takes 30 seconds to set up, so give it a try!

Quick Start: Your First 5 Minutes

Install upstack (30 seconds, see below)
Open your project in Claude Code
Run /advisor to see where you stand
Run /plan on your first feature or bug
Run /execute to build it with TDD
Run /ship-pr to open a PR with screenshots and evidence

Install — Takes 30 Seconds

Install on your machine

Open Claude Code and paste this. Claude does the rest.

Install upstack: clone https://github.com/Upsolve-Labs/upstack.git to ~/.claude/skills/upstack (try HTTPS first, fall back to SSH with git@github.com:Upsolve-Labs/upstack.git if auth fails),

Daftar alat adalah petunjuk metadata, bukan kompatibilitas teruji. Prompt adalah saran.

Mulai dengan tugas kecil

1Baca sumber dan pastikan masukan, keluaran, dependensi, serta izin.
2Minta rencana dari agent. Setujui pengaturan dan biaya sebelum uji terisolasi.
3Periksa hasil dan berkas yang berubah. Laporkan hanya yang dijalankan dan simpan revisi sumber.

Periksa dependensi, kunci API, dan biaya layanan pihak ketiga pada sumber. Repositori publik tidak berarti semua layanan gratis.
