Add the live ui-phase producer path for the UI-consideration probe (Phase 2, WIRE-01). Two small exports on the Phase-1 adapter — proposeElements (the propose-then-confirm view of detected kinds + applicable categories) and autoResolve (the deterministic --auto floor that never dismisses and never auto-backstops an unclassified item, #1110) — plus a post-verification '## 9.5 UI-Consideration Probe' step in ui-phase.md mirroring spec-phase 5.5's RUNTIME_DIR shim + fatal-invoke/malformed-report/zero-applicable fail-closed guards, propose-then-confirm (the partial-cue recall mitigation), and the '## UI Considerations' write-back in the shipped plan-phase.md:921 lift format. autoResolve is the CODE floor; the covered-upgrade stays workflow prose (the two-layer --auto). Un-upgraded backstops route to insufficient_spec -> human_needed at verify, never a silent pass (#1154). Tests: +8 typed (proposeElements shape/determinism, autoResolve never-dismiss, partial-cue strict-subset) — structured-value only. ui-phase.md size baseline ratcheted 15477->24447 (under DEFAULT cap). The plan-phase.md PRE_PHASE6 ceiling stays RED pending #1852 (unchanged from Phase 1). Claude-Session: https://claude.ai/code/session_01BKt4hgNZwXSeJYJtYAQUSS
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
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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.
