Both predicates were written in round 3 and not updated when round 4 widened what they describe, so the catalog that exists to stop a future omission had two of its own. CONFIG.LOCATION.SEAM.scrub-set said "four sources" and listed four. There are five rungs: the two descriptor rungs each additionally walk skillsHome.env (the maintainer's round-4 Minor 3), and the fifth is WRITE_ESCAPE_PERMISSION_ENV_KEYS, which is a permission rather than a location and so is reachable by no other rung. LIVE-CONFIG.GUARD.SEAM.non-root-targets said "the two live write surfaces" and named a single config.toml via resolveKimiHooksTomlDir. Since #2755 landed KIMI_CODE_HOOKS_TOML_DESCRIPTOR there are three, and the guard derives them by iterating NON_REGISTRY_CONFIG_HOME_DESCRIPTORS rather than calling a named resolver. Both bounds are stated rather than left open: skills bases are a deliberate non-target (the config-root layout misfires beneath them), and a further descriptor is only free if it owns the same NON_REGISTRY_OWNED_FILE — the residual the guard already names at its own definition. LIVE-CONFIG.GUARD.SEAM.scope's "gsd--prefixed" read as a two-hyphen prefix; the selector is startsWith(GSD_ARTIFACT_PREFIX) where that constant is 'gsd-'. CONFIG.LOCATION.SEAM.kimi-two-homes was checked and is NOT stale: #2755 made Kimi Code a separate runtime, so Kimi CLI still declares exactly two. Both CONTEXT-INDEX mirrors regenerated; predicate ids unchanged (425), only their descriptions move.
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.
