Realize ADR-857 Branch 8 (host-CLI support as role:runtime Capabilities) + materialize ADR-58's InstallPlan. Closes the 6-axis descriptor vocabulary, absorbs the hard-case runtimes as data, and stages the install migration as a 5a→5g ladder (4/6 axes already modularized; InstallPlan is the 5g capstone, reachable by collection, not a big-bang rewrite). Amended after a plugin-side design grill (rubber-duck + grill-with-docs vs #956 MemPalace / #999 Impeccable): - New term Connected Capability (CONTEXT.md) — a Capability whose integration shape brings its own external process/service/state; orthogonal to authorship. Named, tracked gap (vehicle #956); current schema does not express it. - Narrowed the dogfood claim: the descriptor dogfoods the runtime interface only, not the feature-plugin/Connected path. - Structural "off means off" rule (CONTEXT.md RULESET.CAPABILITY.off-means-off): the host derives shared outputs from active hooks; a hook adds/is-counted, never mutates host source. Ratify in ADR-894; proven by spike #1018. - Hand-waves resolved by code: sandboxTier real-but-thin; model-catalog orthogonal (not a 7th axis); converters closed into a ConverterName enum + added the kimi-agents artifact kind; configHome is pure read-only. - Hook-firing path is unproven (render-hooks built, never consumed) → spike #1018 must prove render-hooks→live-workflow execution before phase-5 build. Design-only; no code. Status: Proposed.

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.
