ADR-1239 gains a ninth negotiated axis, effortSurface (argv | none), declaring how
a host accepts reasoning effort. ADR-443 is amended in the same change because its
recorded deferral is what the axis resolves: its Unblock condition offered paths
(a) and (b) and stated the choice was 'a maintainer call this file records but does
not make'. Path (a) is selected and satisfied here.
Before this, effort reached a runtime only through install-time channels
(EFFORT_RENDERING's frontmatter/api), so reviewer CLIs spawned as subprocesses
silently inherited whatever effort sat in the user's own global CLI config. The
review lane now resolves one universal effort through the ADR-443 cascade and
renders it per host through the negotiated descriptor.
Every per-host value is documentation-sourced, never inferred:
- claude argv -- verified via 'claude --help' (--effort <level>)
- opencode argv -- verified via 'opencode run --help' (--variant)
- codex argv -- codex-rs/exec/src/cli.rs: model_reasoning_effort is NOT a CLI
flag (config.toml key only), so the global -c override is the
only argv route
- 15 hosts undocumented -- their docs state no reasoning setting; the sentinel
fails closed rather than inheriting a profile baseline
No config-file vocabulary member: the only host that ever had one (Gemini CLI's
thinkingConfig) was removed as a sunset runtime by 8f2ebbe9b (#1928, PR #1996),
and neither Antigravity CLI nor ZCode documents a reasoning setting.
Closes #2481

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.
