* docs(#2980): ratify the payload-carried error idiom as a degraded result Records ADR-2980: an `error` key in a gsd-tools result payload on stdout with exit 0 is a ratified contract meaning the command ran to completion and is reporting a condition, not a process failure. Faults keep stderr + exit 1 + --json-errors. Normalizing the 42 output({error}) sites to exit 1 was declined on measured blast radius (get_impact rates cmdStateSnapshot CRITICAL; output has 170 direct callers) — a Hyrum's Law break with no versioning escape hatch for an exit code. Adds the "Degraded results vs faults" section to docs/json-errors.md with a correct-caller recipe, indexes that page from docs/README.md, and records the two-channel contract in the CONTEXT.md I/O Module entry. No code change. Closes #2980 * docs(#2980): correct the site count and cross-refs after review The isolated review found the population figure was the answer to a regex, not to the question. `output\(\{\s*error:` only matches literals whose FIRST key is `error`; re-deriving it by brace-matching output()'s first argument gives 60 sites across 9 modules (42 error-first + 18 error-not-first), adding workstream.cts, phase.cts and gsd2-import.cts. roadmap.cts:260 is the case in point — it carries `error` alongside `found:false` and is the site that actually produces the documented `roadmap get-phase` output. Also from review: correct the --raw claim (11 sites pass a rawValue, not 2), reconcile the missing-required-argument count to the 7 verified sites, link the bare ADR-2966 references per the ADR lifecycle rule, and fix 'licence' to American spelling. --------- Co-authored-by: sim <sim@local>
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.
