* feat(#1680): ADR-1239 Phase C-1 — imperative embedding adapter (composes loadRegistry) [AC2] Phase 3 slice 2 (AC2). The engine-as-library path: createImperativeAdapter composes loadRegistry({includeInstalled:true}) — first-party-wins + consent + fail-closed gates, identical trust semantics to the CLI — and binds the engine surface behind the SAME HostIntegrationInterface the declarative adapter (AC1) satisfies, plus a registry accessor for the composed capability set. - src/adapter-imperative.cts: createImperativeAdapter({runtime}, {loadOptions}) → ImperativeAdapter (kind:'imperative' + .registry + install/uninstall delegating to install-engine). Thin: delegates the loop, does not reimplement. - tests/adapter-imperative.test.cjs: kind (16 runtimes), registry composition (loadRegistry called with includeInstalled:true), loadOptions pass-through, install/uninstall delegation, fail-closed construction. - eslint.config.mjs + docs/INVENTORY-MANIFEST.json: ADR-457 ignores entry + cli_modules entry for the new emitted .cjs (the two drift gates that bit AC1, applied proactively here). Concrete host binding (OpenCode/VS Code/pi) deferred to Phase 5 (#1682). * test: remove dead readStateMd helper from bug-1760 test readStateMd was defined but never called (writeStateMd is the only state-md helper this test uses). Clears the lone no-unused-vars warning so the repo lints fully clean (0 problems). No behavior change — test still passes 2/2. * chore(changeset): add Changed fragment for imperative embedding adapter (#1680) * fix(adapter-imperative): reword comment to avoid injection-scan substring match The prompt-injection scan regex 'act\s+as\s+(?:a|an|the)' was matching the 'act as the' substring inside 'contract as the declarative adapter' (contrACT AS THE). Reword 'contract as' -> 'shape as' — no 'act' substring, identical meaning. Clears the 'lib source files are clean' + 'codebase prompt injection scan' security-gate failures.
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.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start your first project:
/gsd-new-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.
