Fold CodeBuddy's residual runtime-literal branches onto descriptor-driven hostBehaviors (the issue's "zero branches remain" premise was inaccurate — 2 lived): - Folded the `if (isCodebuddy)` commands/ report duplicate (byte-identical to the generic reportCommandsDir block above it) onto hostBehaviors.reportCommandsDir:true, matching cursor's #2089 precedent. - Deleted the dead `else if (isCodebuddy)` agent-conversion arm (codebuddy ∈ _DESCRIPTOR_AGENTS_RUNTIMES → gated out before the legacy chain, same dead-arm pattern removed for augment/trae in #2097). - Removed isCodebuddy from all 4 destructure sites (now comments only, mirroring the #2096 isAntigravity fold). Zero live isCodebuddy reads remain. UPGRADE 1 (extended hook bus): populate extendedHookEvents with the full extended set SubagentStop/Stop/PreCompact/SubagentStart (qwen #2092 / kimi precedent — codebuddy previously had extendedHookEvents:[] so it got NONE of these). The generic applySettingsJsonHooks loop wires them, so CodeBuddy's settings.json now gains all four subagent-lifecycle + stop/compact hooks it previously lacked, matching Qwen/Kimi coverage. No source change (the HOOK_EVENT_SURFACES SDK catalog is a locked dict; all 4 events are already in the validator enum; hookEvents already 'claude'). settings.json is golden- excluded → no golden change. UPGRADE 2 (background dispatch): surfaced via the negotiated capability contract only. CodeBuddy's dispatch.background:true legitimately exceeds the declarative- cli baseline (false) and survives negotiation with no warning. NO agent-file frontmatter field is emitted: the CodeBuddy CLI (GSD's install target, ~/.codebuddy/agents/) has NO background-dispatch frontmatter field — background is a caller-side run_in_background invocation param (verified against codebuddy.ai/docs/cli/sub-agents); the issue's agentMode/enabledAutoRun are IDE-only (codebuddy.cn, a different product). Emitting them would be a non- functional false-green, so it is deliberately not done. Golden: byte-identical for all 16 runtimes (folds are console/failures-report only; UPGRADE 1 → golden-excluded settings.json; UPGRADE 2 → no artifact change). Tests: declarative-reference-codebuddy (adapter/axes/fail-closed negotiation + AC2 source-grep guard) + codebuddy-upgrades (live install asserts all 4 extended hooks wired; dispatch.background survives negotiation above baseline). Matrix + install-on-your-runtime updated; 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.
