@FakeMaidenMaker: Definitely bookmark this tool that cures Claude Code's 'messier as you write' problem — GSD. Its predecessor Get Shit Done racked up 64K Stars on GitHub, and it's now migrated to GSD Core for continued maintenance. Let Claude Code tackle a slightly larger task…
Summary
GSD Core is an open-source workflow framework that solves the problem of context pollution and code quality degradation in AI coding tools like Claude Code during long tasks through a five-step cycle of 'Discussion → Planning → Execution → Verification → Delivery' and sub-agents with independent contexts. It has gained 64K Stars on GitHub.

You must bookmark this tool that can cure Claude Code’s “messier as it goes” problem — GSD, formerly known as Get Shit Done, has amassed 64K stars on GitHub and has now migrated to GSD Core for continued maintenance. When you ask Claude Code to handle a moderately large task, the biggest pitfall is that the context window gets stuffed as you go, causing the quality of later responses to drop sharply, and the AI often modifies code it shouldn’t have touched. GSD breaks down the entire development process into a five-step loop: Discuss → Plan → Execute → Verify → Ship. Each heavy step is handed off to a subagent that runs in a fresh context, keeping the main session clean and unburdened by accumulated earlier information. The author, TÂCHES, has turned this approach into a one-click install workflow that works with Claude Code, Codex, Cursor, Gemini CLI, and more. Deployment is simple: install with npx @opengsd/gsd-core@latest and run /gsd-new-project to get started.

What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Gemini CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Gemini CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start your first project:
/gsd-new-project

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done.
See docs/explanation/context-engineering.md for the full reasoning.
