* test(#4444): failing-first regression coverage for config-set --dry-run config-set --dry-run is currently parsed nowhere -- routeConfigSet (gsd-core/bin/gsd-tools.cjs) never checks args for it, and cmdConfigSet has no dry-run parameter, so the flag is silently swallowed and the command always writes for real. Reproduces the issue's own repro (sequential --dry-run calls where the second's previousValue proves the first persisted), plus coverage for validation-still-runs, secret-masking, and the sibling unset (config-set <key> null) branch, which has the identical defect. This commit adds the regression coverage only; the fix lands in the next commit. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4444): honor config-set --dry-run instead of silently ignoring it routeConfigSet (gsd-core/bin/gsd-tools.cjs) never read args for --dry-run, and cmdConfigSet had no dry-run parameter at all -- so the flag was silently accepted (as any unrecognized trailing argument is) and the command always wrote for real. A second "dry run" then showed previousValue reflecting the first one, proving it had persisted. Threads a dryRun option through cmdConfigSet, gating BOTH mutating branches: the null/unset path (unsetConfigValue) and the real-set path (setConfigValue) -- the unset branch had the identical defect, undiscovered until auditing every mutation site while designing this fix. Each gains a previewConfigValue/previewUnsetConfigValue counterpart that reuses the real function's exact traversal/creation logic (_setNestedValue/_unsetNestedValue) on a throwaway in-memory config copy that is never written -- so the preview can never diverge from what the real write would compute. All validation (unknown key, enum/number/boolean checks, secret masking) runs identically whether or not --dry-run is passed; only the final write is skipped, replaced with a `{ dry_run: true, would_update / would_unset: true, ... }` preview payload matching the precedent established by `milestone complete --dry-run` (#2118) and `todo complete --dry-run` (#4096/#4325). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(#4444): extract loadConfigJson to stop a 5th copy-paste of the same load/parse block Code review flagged that setConfigValue, unsetConfigValue, setConfigValues, and the two new preview functions each repeated the identical "load .planning/config.json, JSON.parse, catch -> CONFIG_PARSE_FAILED" block -- exactly CLAUDE.md's own "Generative Fix Divergence" known-defect pattern. Extracted a single loadConfigJson(cwd) helper; behavior is unchanged (verified: build, tsc, and the dry-run/real-write smoke test all pass byte-identical to before).

Raised RUN_TESTS_CHUNK_TIMEOUT_MS's default from 600000ms to 800000ms: ~33% more margin, still comfortably below the 900000ms regen:derived fixture timeout that fragment-single-edit-propagation.install.test.cjs deliberately keeps ABOVE the chunk ceiling, and far under the 45-minute job cap -- Windows shards currently finish in ~19-20 minutes total, so there is ample headroom. Updated every dependent mirror/assertion in lockstep (tests/helpers/emitted-runtime.cjs's duplicated CHUNK_TIMEOUT_CEILING_MS constant, its lock test in tests/emitted-attribution.test.cjs, the Windows-skip prose in fragment-single-edit-propagation.install.test.cjs, and docs/TESTING-SUITES.md's reference table) so nothing describes a stale value. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Revert "fix(#4444): raise per-chunk CI test timeout to 800s for Windows headroom" This reverts commit 394aadaf6f5af6fd700bf0f444c9fbd686285a4f. * test(#4444): consolidate redundant installer spawns in install-minimal-hooks.test.cjs This file's real, unrelated pre-existing cost (dated 2026-09-06, PR #4428) is what tipped a Windows CI shard over the per-chunk timeout backstop on PR #4504 (issue #4444's own diff never touches this file or the installer). Rather than raise the timeout, cut the file's actual spawn count: several describe blocks independently re-installed the IDENTICAL runtime/scope/flag configuration just to assert different things about the same install output. Merged each such group onto a single shared install, with every original assertion preserved: - --help x3 -> x1 - the three per-runtime/scope --minimal E2E loops (global, local, and on-disk-matches-manifest) merged into one loop over SKILL_RUNTIMES x [global, local]: 44 spawns -> 22 - the --minimal manifest-mode/backcompat triple-install -> one shared, memoized install via sharedMinimalManifestInstall() - .sh hooks existence checks (5 tests) -> 1, executable-bit check (its own Windows-conditional skip) left separate - Codex #4087 hook-helper tests (3) -> 1 - Windsurf #4087 hook-helper tests (2) -> 1 - pi shared-hooks-bundle tests (3 per scope) -> 1 per scope Net: ~65 real installer spawns in this file down to ~29, no assertion dropped or weakened.

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.
