Phase 0 of epic #2866. Records the decision that the install pipeline resolves surface identity — (runtime × scope × trigger) — as a value instead of implying it from destination paths. The ADR makes four things explicit: - Amends ADR-3660 (placement -> placement + trigger resolution) and says why placement-only stopped paying: the /gsd-<name> trigger two artifacts collide on is not a value anywhere, so #2218 cannot be stated by any module or test. - Adds one axis to ADR-1016's deliberately-closed descriptor vocabulary (host trigger precedence), required-with-default so ADR-894's additive-only stability contract holds. - Records the @-include constraint (expands ~, does NOT expand env vars, no conditional syntax) as the reason #2218 triage option 1 is REFUTED rather than merely deprioritized. - Notes the non-conflicts: completes ADR-58 rather than revising it, and preserves ADR-1508's dependency direction. ADR-3660 and ADR-1016 each gain the reciprocal Amended by back-link, matching the corpus convention ADR-2782 already set on ADR-1016. Each states that the decision is recorded now while the modules change at Phase 2 (#2871), so no reader is told a widening has already shipped. Also corrects CONTEXT.md's Installer Module entry: bin/install.js is hand-authored, not generated. ADR-1508 states this verbatim and no build step emits it; the stale annotation invites contributors to look for a generator that does not exist. Docs-only. Verified via the remote runner.

GSD Core
Git. Ship. Done.
English · Português · 简体中文 · 日本語 · 한국어
A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity 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, Antigravity 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 a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase

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.
