open-gsd · Spec-Driven Agent Coding

GSD Core

A meta-prompting and spec-driven development framework that runs AI coding agents in a five-step loop per phase: discuss, plan, execute, verify, ship. It fights context rot by pushing research, planning and execution into fresh-context subagents, each starting with a clean 200k-token window, and keeps state across sessions in files such as STATE.md and CONTEXT.md. Installs with npx @opengsd/gsd-core into Claude Code, OpenCode, Codex, Copilot, Cursor, Windsurf, Kimi CLI and others. MIT, 10,139 stars, v1.15.0 on 26 September after weekly releases since August.
