What problem does it solve? AI coding agents lack structured, repeatable workflows for the full software development lifecycle, leading to inconsistent reviews, missed bugs, and ad-hoc shipping processes. gstack gives agents specialist roles (CEO reviewer, eng manager, designer, QA lead, release engineer) plus a persistent headless browser so every phase of development follows a disciplined procedure. ## Core Features & Use Cases - Workflow skills: 20+ invocable skills covering plan review (/plan-ceo-review, /plan-eng-review, /plan-design-review), code review (/review), debugging (/debug), QA (/qa, /qa-only), shipping (/ship), documentation (/document-release), and retrospectives (/retro). - Persistent headless browser: A compiled CLI daemon ($B) driving Chromium via Playwright with ~100ms command latency, ref-based element selection, cookie import, and a real-Chrome headed mode with a sidebar agent. - AI design generation: A design binary ($D) wrapping the GPT Image API to generate UI mockups, comparison boards, and design-to-code prompts. - Safety guardrails: /careful, /freeze, and /guard skills warn or block destructive commands and restrict edits to specific directories. - Use Case: A developer finishes a feature branch and runs /ship — the skill runs tests, audits plan completion against the diff, checks test coverage gates, writes the CHANGELOG entry, pushes, and opens a PR in one command. ## Quick Start Ask the agent to run /office-hours to reframe your product idea, then use /plan-eng-review and /ship to take it from plan to merged pull request.
