Two tests for round 3's change (round 2 Blockers 1 and 2): KIMI_SHARE_DIR must arrive via NON_REGISTRY_CONFIG_HOME_DESCRIPTORS rather than a literal, and every GSD_LOCATION_ENV_KEYS entry must be blanked. Both assert a floor on their source first, so a renamed export fails loudly instead of passing vacuously. Negative-controlled against the registry-only derivation: both fail there, and only those two. And the Nit, which is the more useful half. This block asserts that TEST_ENV_BASE is not narrower than the enumerations it derives from. It cannot prove those enumerations are complete — a var no enumeration carries is invisible to every test here, and they stay green. That is exactly how round 2 found GSD_HOME and KIMI_SHARE_DIR while this block was fully green: one belonged to no enumeration at all, the other sat inside a function body where nothing could enumerate it. So the scope boundary is now written down at the top of the block, naming where the completeness question is actually answered — a source census re-derived each round, and live-config-guard.cjs observing real writes at runtime — so that a green run here is not misread as "the set is exhaustive." Deliberately NOT added: an assertion per reviewer-named variable. That is the hand-maintained list wearing a test's clothes, and it fails the same way.

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.
