Aperçu

gstack is an open-source workflow system designed to extend AI coding assistants like Claude Code and Codex with structured engineering practices. Instead of treating AI as a freeform chat partner, it introduces explicit skills for planning work, reviewing changes, running QA, and shipping code, helping teams move from prototype prompts to repeatable development loops. By codifying common stages of a software project into reusable skills, gstack aims to make AI-assisted development more predictable and auditable. It fits into existing repositories and developer workflows, letting engineers invoke the right skill at the right step rather than reinventing prompts for each task.

Cas d’usage

Structured planning for AI coding tasks

Use the planning skill to break a feature request into clear steps before Claude Code or Codex starts writing code, reducing drift and rework.

Automated code review loop

Invoke the review skill on AI-generated diffs to catch issues early and enforce consistent engineering standards across pull requests.

QA and testing checkpoints

Run the QA workflow after changes to systematically validate behavior, helping teams ship AI-assisted code with more confidence.

Repeatable plan-to-ship pipeline

Chain planning, review, QA, and shipping skills into a standard development loop so teams move from prototype prompts to predictable releases.

Pour & contre

Open source and customizable
Covers the full plan-to-ship loop
Encourages repeatable engineering practices

Contre

Requires learning its skill model
Tied to specific AI coding agents
Setup overhead for small projects
Quality depends on underlying model

Use it every day

Honestly didn't expect to like it this much. Code review skill is exactly what I needed, and encourages repeatable engineering practices. I do wish setup overhead for small projects, but I reach for it almost every day now and it just clicks.

Wei Chen

Years in this space

I've evaluated a lot of these over the years. What stands out here is qA and testing workflows — handled better than most — and adds structure to AI coding sessions. Quality depends on underlying model is my one real gripe. Worth the time if this is your use case.

Mei-Ling Wong

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on structured planning skill, and adds structure to AI coding sessions caught me off guard. Requires learning its skill model is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Omar Haddad

Solid for our team

We rolled this out across the team last quarter and open source and customizable. Shipping and release helpers fits neatly into how we already work, and shipping and release helpers removed a step we used to do by hand. but it has held up under daily use.

Questions & réponses

Which AI coding assistants does gstack integrate with?

gstack is built to extend Claude Code and Codex specifically, adding structured planning, review, QA, and shipping skills on top of them. It's tied to these agents, so teams using other AI coding tools won't get direct support out of the box.

Is gstack worth the setup overhead for small projects or solo developers?

gstack adds structure and repeatability that shine on ongoing team projects, but it carries setup overhead and a learning curve for its skill model. For small or one-off projects, that investment may outweigh the benefits compared to ad-hoc prompting.

How much does gstack cost and what's the licensing model?

gstack is open-source, so the workflow layer itself is free to use and customize. You'll still need access to the underlying AI coding agents (Claude Code or Codex), which have their own pricing from their respective providers.
