* test(#3336): fold the installer & runtime surface issue-* cluster — Wave 4 Folds 10 legacy issue-*.test.cjs regression files (79 test() blocks) into their module's main suite, per H3 (#3315) of the test-hygiene epic (#3053). First of 4 issue-* waves (following the 3 fix-* waves, all merged). - 1 file with no prior target coverage: renamed (git mv) into legacy-cleanup.test.cjs (sole comprehensive suite for that module). - 9 files merged into 6 pre-existing suites: golden-parity-single-source, runtime-artifact-layout-surface, codex-config (4 sources merged jointly in one pass per the issue's own instruction, to catch overlap between the 4 sources themselves, not just against the pre-existing target — zero overlap found, all 20 blocks additive), runtime-config-adapter-registry (1 of 10 source blocks dropped as a proven subset of existing coverage), cline-install, install.test.cjs. Incidental fixes required to keep this wave's own ratchets green: - Fixed a stale ADR doc reference (docs/adr/1235) to a folded-away filename. - scripts/lint-allow-test-rule-refs: pruned 4 stale allowlist entries for renamed/merged-away files, cited 2 previously-uncited allow-test-rule comments that surfaced as "new" only because their file path changed, added 1 fresh allowlist entry for a pre-existing uncited comment that predates this PR, and tightened the exemption-file ceiling 309 -> 305 to match the real post-fold high-water mark. Zero net test-coverage loss. No production code changed. * test(#3336): fix orthogonal-review findings — Wave 4 fold Standards-axis review + Memtrace graph pass found real issues in the just-folded suites, all fixed here: - Standardized the fold-wrapper convention (block-scoped __foldDescribe) across golden-parity-single-source.test.cjs, runtime-artifact-layout- surface.test.cjs, runtime-config-adapter-registry.test.cjs, and cline-install.test.cjs to match the pattern already used by codex-config.test.cjs and install.test.cjs in this same wave (and by earlier folds elsewhere in the epic) — repeats the exact inconsistency Wave 3 (#3335) already fixed once in this epic. - Fixed a stale allowlist entry's alphabetical position (cosmetic, not tool-gated, caught by review anyway). - Fixed two stale test-filename references in PRODUCTION code comments (src/capability-writer.cts, src/runtime-config-adapter-registry.cts) caught by lint-removed-but-needed — a class of stale reference this wave's fold agents didn't check for, since they were scoped to docs/ and gsd-core/references/ only, not src/. First fix attempt wrongly edited the gitignored gsd-core/bin/lib/*.cjs BUILD OUTPUT instead of the tracked .cts source; caught and corrected before commit. - Fixed one remaining stale doc reference in docs/adr/1235 (a prior partial fix in this same wave missed it). No test() count changed in any file. No production code BEHAVIOR changed — comment-only fixes in src/. --------- Co-authored-by: sim <sim@local>
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.
