* fix(#2667): mediate .cmd/.bat/.exe spawns on Windows; split fallow pre-pass failure diagnostic
run-with-timeout spawned .cmd/.bat/.exe commands without shell:true on Windows,
tripping Node's CVE-2024-27980 EINVAL (April 2024 security hardening). The fallow
structural pre-pass then no-op'd silently — a hard execution failure read the same
as 'optional dependency absent'.
(A) gsd-core/bin/gsd-tools.cjs runWithTimeout: gate shell:true on
(win32 && command ends in .cmd/.bat/.exe). Narrow by design — never fires for
the 7 `bash -c` callers (command is `bash`, no such suffix), so the recorded
no-shell-for-argv-array security contract (DEFECT.UNBOUNDED-SUBPROCESS) is
preserved; cmdArgs stays an array. POSIX untouched.
(B) code-review.md fallow pre-pass: name the failure KIND (timeout / spawn failure
/ crash / not-found) so a Windows .cmd spawn failure is not mistaken for an
absent binary.
Regression test in tests/run-with-timeout.test.cjs gated to win32 (.cmd/.bat/.exe
shims run with exit 0 + non-empty stdout; pre-fix EINVAL → exit 125/empty). POSIX
negative-space test guards the unchanged bash -c callers.
* chore(#2667): changeset fragment
* chore(#2667): backfill changeset PR 2897 + correct body (cmd.exe array, not shell:true)
* fix(#2667): exclude .exe from the win32 spawn-mediation gate; ack code-review.md growth
CI caught two failures on the first push:
1. windows-24: 'exits 124 when the wall-clock budget is exceeded' regressed. The
gate matched .exe, so the HANG command (node.exe -e 'setTimeout(...)') was
wrapped in 'cmd.exe /c node.exe ...' — the wrapped child escaped the timeout
cap's process-group reap (exit 124 never fired; hit the 30s harness backstop)
AND cmd.exe risked mis-parsing the -e script arg. .exe is INTENTIONALLY
excluded now: real PE executables spawn fine directly; only .cmd/.bat are the
CVE-2024-27980 EINVAL cases. The .exe test becomes a negative-space test
(node.exe spawned directly, exit 0).
2. ubuntu-22: emitted-attribution — code-review.md grew 1177 bytes from the
#2667 fallow pre-pass failure-KIND case statement; acknowledge it.

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.
