* test(#4515): migrate installer-runs batch to named timeout constants Batch 4 of the ad hoc timeout literal migration (epic #4445). Replaces every bare numeric timeout/timeoutMs object-literal property across tests/install.test.cjs, tests/install-minimal-hooks.test.cjs, tests/fragment-single-edit-propagation.install.test.cjs, tests/install-regressions.test.cjs, tests/install-runtime-artifacts.test.cjs, tests/npm-integrity-gate.test.cjs, tests/faulty-deps.test.cjs, tests/release-tarball-smoke.install.test.cjs, tests/install-write-confinement.test.cjs, tests/plugin-manifest.test.cjs, and tests/packaging-shipped-scripts-require-only-shipped.test.cjs with a named constant, per eslint-rules/no-adhoc-timeout-literal.cjs. Removes these 11 files from the rule's allowlist. Adds one new shared constant to tests/helpers/timeouts.cjs for a fixture-JSON value (in seconds, not ms) mimicking a Claude Code settings.json hook-entry's own timeout field, shared across two files in this batch. Every other new constant is file-local, each carrying a comment explaining why its call site is a distinct operational class from the existing shared norms even where its digits numerically coincide with one. No src/bin file touched, no numeric timeout value changed anywhere. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: combine gsd-worktree-path-guard's git rev-parse calls to cut subprocess count under CI load Discovered while verifying PR #4575 (a full test (windows-latest) failure in an unrelated test, tests/kilo-upgrades.test.cjs's worktree-path-guard rejection test). Root cause: this hook's up-to-4 sequential git spawns (git-dir, branch, worktree-toplevel, file-toplevel), invoked inside a native-plugin's own 8000ms-capped subprocess wrapper, left zero margin for node/git startup overhead — the guard is deliberately fail-open on any timeout, so CI-load-induced latency in this chain silently downgrades a security block into an allow. Combines the first three git rev-parse calls (git-dir, branch via --abbrev-ref, worktree-toplevel) into ONE spawn instead of three, using git's documented multi-flag rev-parse output (one line per flag, in order) — verified empirically including the detached-HEAD edge case. No timeout value changed; this reduces subprocess COUNT, not any tolerance.

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.
