* refactor(#1511): move content-rewrite engine to conversion module, delete the install.js relay Phase 2 of epic #1507 (ADR-1508). Behavior-preserving: makes the Runtime Artifact Conversion Module the single owner of per-runtime content rewriting and removes the last upward .cts -> bin/install.js dependency. - src/runtime-artifact-conversion.cts now owns the engine (_applyRuntimeRewrites, 5-arg with INJECTED attribution), the staged-content walkers (applyRuntimeContentRewritesInPlace / ...ForCommandsInPlace), computePathPrefix (private, exported as _computePathPrefix for tests), and the deep public seam rewriteStagedSkillBodies / rewriteStagedCommandBodies({runtime, configDir, scope, homedir?, platform?, resolveAttribution?}). - src/surface.cts:applySurface calls rewriteStagedSkillBodies directly (no resolveAttribution -> undefined). Co-Authored-By is absent from ALL rewritten content, so processAttribution is vacuous there and undefined is provably behavior-identical. surface no longer imports getInstallExports. - src/runtime-artifact-layout.cts: deleted getInstallExports / loadInstallExports / InstallExports + the GSD_TEST_MODE require('bin/install.js') relay. - bin/install.js: binds computePathPrefix / the two walkers / _applyRuntimeRewrites from the conversion module (single implementation, exports preserved for Hyrum); install callsites pass getCommitAttribution(runtime) as the injected attribution. getCommitAttribution stays here (impure install-time config I/O). - DEFECT.GENERATIVE-FIX guard: tests assert install.X === conversion.X reference identity for computePathPrefix + both walkers (no drift). New tests/enh-1511-*.test.cjs (engine, attribution injection, deep seam, prefix, layout-no-relay guard, reference-identity). 316 affected-suite tests green; lint clean.

Three assertions in the new test rebuilt expected paths without that normalization, so they passed on Mac/Linux but failed on Windows CI (PR #1513): - two absolute-branch asserts rebuilt resolvedTarget via path.resolve(configDir) without the backslash→slash replace → mismatch on Windows. - the $HOME-branch test fed a POSIX-literal /home/testuser, which Windows path.resolve re-roots onto the cwd drive (D:/home/...), so the resolvedTarget.startsWith(homeDir) check failed and the $HOME shorthand was never produced. Fix is test-only (engine unchanged, still behavior-preserving): mirror the engine's .replace(/\\/g,'/') in the two absolute-branch asserts, and use a real absolute path (path.resolve(os.tmpdir(), ...)) + platform: process.platform for the $HOME-branch test so the comparison holds on all platforms.

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, Gemini 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, Gemini 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, Gemini 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.

Once installed, start your first project:

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.
