* fix(#4558): report a byte-identical restore destination as already_present restore-custom-files treated a destination that is byte-identical to its backup exactly like a missing one: plan reported it as `eligible`, --apply re-copied the same bytes and reported `restored`, and both counters included it. Because update.md drives its restore question off eligible_count, the workflow re-offered the same no-op restore on every update and accepting it never settled anything. Emit a distinct `already_present` outcome for that case. It is excluded from eligible_count and restored_count, --apply writes nothing for it, and the backup is left intact. A differing destination is still skipped_destination_exists and a missing one still restores normally. Regression tests cover the identical-destination plan/apply paths, the idempotence-after-success cycle (missing -> restored -> silent plan), and a mixed backup. Docs for the outcome enum are updated to match. * fix(#4558): tighten already_present wording after review update.md's RESTORE_ELIGIBLE == 0 branch now also names the already-present case, CLI-TOOLS.md no longer calls the follow-up plan run "silent" (the entry is still reported, just never offered), and a test message reads correctly. * chore(#4558): add changeset fragment for #4599 * chore(#4558): acknowledge update.md growth from the restore-outcome guidance Emitted-Drift-Ack-Growth: update.md — added already_present restore-outcome guidance for #4558 --------- Co-authored-by: TwistedRiCen <16397953+TwistedRiCen@users.noreply.github.com> Co-authored-by: Tom Boucher <trekkie@nomorestars.com>
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.
