Drop code whose only consumer was a retired runtime: hostBehaviors readers for agentFileExtension, localTargetIsProjectRoot, sharedHooksDirName, skillsManifestPrefix and skipCodexSkillsManifest; the empty NON_REGISTRY_CONFIG_HOME_DESCRIPTORS array and live-config-guard plumbing; the empty RUNTIME_NOTE_AUDIENCE_BY_HEADING filter; the unused resolveVersionFrom export; and the WINDSURF_SESSION_ID workstream session key. Delete tests that only exercised those mechanisms.
MSD Core

A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Codex, Cursor, and more.
What is MSD Core
MSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, 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
MSD Core is a private fork and is not published to npm. Install from the checkout:
git clone git@git.golem15.com:golem15/msd-core.git
cd msd-core
scripts/install-golem15.sh # Node 24; installs for Claude Code and Codex
For any other runtime, run node bin/install.js directly. The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Codex, Cursor, 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:
/msd-new-project # greenfield project
/msd-onboard # existing codebase
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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. MSD 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.
