gstack▌

Converts an approved mockup or design direction into production-oriented HTML/CSS with computed layout and framework-aware output expectations.

Variant-generation workflow for visual exploration. It shows multiple design directions, gathers structured feedback, and iterates toward a preferred direction.

Design system creation workflow that researches comparable products, proposes an aesthetic system, and writes `DESIGN.md` as the canonical design source of truth.

Lets users tune how often gstack asks certain planning questions and inspect the psychographic/developer profile inferred from prior interactions.

Orchestrates CEO, design, eng, and DX reviews from disk and applies internal decision principles to auto-progress the plan, surfacing only taste-sensitive decisions at the end.

DevEx review for developer-facing products. It explores personas, benchmarks onboarding, and scores friction across APIs, CLIs, SDKs, libraries, docs, and platform flows.

Interactive design-plan review that scores design quality, identifies unresolved UX issues, and improves the plan before anyone ships UI.

Engineering-manager style review that hardens the plan around architecture, boundaries, state transitions, edge cases, tests, and diagrams before coding starts.

Founder-mode review that asks what product is really being built, not just what feature was requested. Supports scope expansion, selective expansion, hold-scope, and scope-reduction modes.

YC Office Hours with two modes. Startup mode asks six forcing questions around demand reality, status quo, specificity, wedge, observation, and future-fit. Builder mode is for side projects and open source. It saves a design doc and is intended to run before implementation work.
