* docs(#2674): amend adr-1411 with the corrupt-is-not-absent house pattern ADR-1411 reasons only about a resolution miss. It is silent on input that is present but not usable, which is how five engine read paths (#1879) could fold an unusable input into the value meaning 'genuinely absent' without contradicting an Accepted ADR. Read together, ADR-1411 and ADR-227 converge and do not license throwing as the cluster's answer: ADR-227 requires malformed input to be coerced rather than propagated and carves out only genuinely-fatal fields, while ADR-1411 already permits a fallback provided it is 'a visible value, not a silent substitution'. The defect in these five sites is therefore not that they fall back but that they fall back invisibly. Records the pattern that follows: every current return value is preserved, and the cause is made visible in-band where the result already carries a provenance envelope, or out-of-band via a deduplicated stderr diagnostic where it returns a bare value it cannot extend. Throwing stays confined to ADR-227's genuinely-fatal carve-out, decided per call. Also names the per-applier caller audit and the lint-resolution-provenance registry gap. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2674): prove the warning-state reset misses the unknown-key dedup set The two existing cases in this suite only pass because each picks a key name no other case reuses, so neither can observe whether the reset the beforeEach calls actually runs. Failing-first: asserts the exported _warnedUnknownConfigKeys is empty after _resetRuntimeWarningCacheForTests(). It is not - the helper clears only _warnedConfigKeys despite documenting itself as resetting per-process warning state. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2674): reset the unknown-key dedup set with the runtime warning cache _resetRuntimeWarningCacheForTests documents itself as resetting per-process warning state but cleared only _warnedConfigKeys, leaving _warnedUnknownConfigKeys populated across cases. The suite that exists to test that set - 'loadConfig - unknown-key warning dedup' - calls the helper in beforeEach expecting exactly this, so the reset was a silent no-op for it; both cases passed only because each picked a key name the other never reused. Any later case reusing a key would have had its warning suppressed by leaked state. Found while amending ADR-1411, which names this dedup guard as the pattern five downstream PRs (#1880-#1884) will adopt - shipping the ADR without the fix would have propagated the footgun to each of them. Folded in here per CLAUDE.md's no-defer rule rather than filed. RED verified on 3c4895841 (test only, no fix): linux-node22 reported 'FAIL tests/config-loader.test.cjs - the documented per-process warning-state reset must clear the unknown-key dedup set too'. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): document src/ in the changeset-lint trigger list CONTRIBUTING.md presented the Changeset Required trigger list as bin/, gsd-core/, agents/, commands/, hooks/, sdk/src/ - omitting src/, which scripts/changeset/lint.cjs has in USER_FACING_PREFIXES. src/ is the TypeScript source of truth compiled into gsd-core/bin/lib/*.cjs, so it is the most-edited user-facing path in the repo and the omission sends any contributor who touches it into a CI failure the doc says cannot happen. Also documents that the lint reads GITHUB_BASE_REF, which only CI sets, so running it bare locally reports success without evaluating the branch. This PR hit exactly that: a local run said ok_fragment_present and CI failed fail_missing_fragment on the same diff. Found while opening this PR; folded in per the no-defer rule. Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): add Fixed changeset for the src/ trigger-list and reset fixes Refs #1879 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2674): restore the round-2 review corrections to the amendment These edits were made in response to the second isolated review pass but never staged: later commits used targeted `git add <file>` for the test and the source fix, so the two markdown files stayed dirty and shipped nothing. The branch carried the round-1 text, including the ADR-227 misquote the reviewer raised as a blocker. Restores: the unconditional-diagnostic clause (ADR-227's GSD_DEBUG opt-in was never implemented, so citing it as the precedent was wrong), the dedup key, #1882 folded into the out-of-band mechanism instead of a fourth mechanism-less category, the narrowed caller-audit rationale, and the test-methodology clause.

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.
