Fold all 10 residual isWindsurf branches in bin/install.js onto descriptor-driven hostBehaviors (byte-parity — no fold changes any install output): - 2 dead destructures dropped (uninstall, finishInstall); the dead `else if (isWindsurf)` legacy agent-loop arm removed (windsurf ∈ _DESCRIPTOR_AGENTS_RUNTIMES → unreachable). - skipSharedHooksInstall:true folds the two `!isWindsurf` shared-hooks exclusions. - legacyDevinSkillsCleanup:true folds the `.devin`→`.windsurf` one-time cleanup gate. - installsCommandBodiesForWorkflowDelegation:true folds the #1629 command-body copy (workflow-delegation target — load-bearing; local-install verified intact). - verificationStyle:"windsurf-workflows" folds the workflow-count report. - Corrected stale _LEGACY_SCAN_SUBDIR_NAMES + hooks-json manifest comments (cursor + windsurf). Zero live runtime==='windsurf'/isWindsurf branches remain across bin/install.js, install-engine.cts, surface.cts, runtime-artifact-conversion.cts (AC2 guard scans all four). UPGRADE (Cascade hook bus): wire GSD's write/command safety guards into Windsurf's native hook bus. New hooksSurface 'windsurf-hooks-json' (VALID_HOOKS_SURFACES 7→8, GATE A profile-marker-only allowlist, the HooksSurface union) + writeWindsurfHooksJson (Cursor-templated, Cascade's flat {hooks:{<event>:[{command}]}} shape) writing .windsurf/hooks.json with two BLOCKING pre-hooks: - pre_write_code → gsd-windsurf-pre-write.js: blocks writes to a file outside the active git worktree / into .git internals. - pre_run_command → gsd-windsurf-pre-command.js: conservative destructive-command deny-list (rm -rf of root/home incl. sudo/env/path-prefixed forms; fork bombs; force-push refspec forms — HEAD:main, +main, --force/-f — to main/master/next). Both use Cascade's protocol (stdin JSON, exit 2 + stderr to block, exit 0 to allow, fail-open on error/timeout). Tokenize-based classifier (no catastrophic-backtracking regex; 4096-char cap) with the fail-closed false-positives fixed post-review. The 4 advisory GSD guards + pre_mcp_tool_use + 5 post_* logging events are deliberately NOT wired: Cascade has no context-injection channel for advisory hooks and GSD has no MCP guard — porting them would be non-functional padding (documented; codebuddy #2098 / copilot #2099 faithful-subset precedent). extendedHookEvents stays []. Golden: the 2 guard scripts ship in the shared hook bundle (HOOKS_TO_COPY + the shared managed-hooks-registry), exactly like cursor's 6 gsd-cursor-*.js scripts — so the 8 shared-bundle runtimes' fixtures gain the 2 inert windsurf scripts + the registry hash (functionally inert for non-windsurf; the established cursor pattern). No install-output change beyond that (the folds are byte-parity; skip-bundle runtimes untouched). New scripts registered in managed-hooks-registry + build-hooks + INVENTORY. Tests: declarative-reference- windsurf (adapter/axes/fail-closed + AC2 guard) + windsurf-hooks-bridge (live exit-2 blocking + allow/fail-open + ReDoS-bound + writer/reconcile/remove idempotency); VALID_HOOKS_SURFACES pin updated to 8. Matrix hookBus delta + changeset (Changed). capability-registry regenerated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.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

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.
