* fix(#4112): ban GNU-only grep -P in workflow markdown to prevent macOS regressions Add scripts/lint-portable-grep.cjs, wire it into lint:ci, and add tests/lint-portable-grep.test.cjs. The #4112 shell-syntax fix newly exposed a pre-existing grep -oP invocation that silently resolves to "" on stock macOS's BSD grep (no -P support). This ratchet catches the same class of GNU-coreutils assumption before it merges, mirroring lint-portable-timeout.cjs. * fix(#4112): drop unneeded ls -l long-format that broke basename/dirname extraction The previous commit on this branch replaced grep -oP 'phases/\K[^/]+' (GNU-only, silently fails on macOS's BSD grep) with basename "$(dirname "$phase")"), but left ls -lt (long format, -l) in place. -l output is a full detail line (permissions, owner, size, date, path), not a bare path, so dirname on that string throws "illegal option -- r" (BSD) / errors under GNU coreutils too -- the extraction never produced a usable value, on any platform. -l was never needed here; only mtime-sort plus the bare path mattered. Dropping it to ls -t restores one-bare-path-per-line output, which basename/dirname actually requires. Confirmed on gsd-test's Linux bench: the #4112 regression test (tests/pause-work-context-detection.test.cjs) now passes phase, spike, and sketch resolution. Emitted-Drift-Ack-Growth: pause-work.md — portability fix (#4112): dropping grep -oP for a portable basename/dirname extraction is a few characters longer per line; no functional growth beyond the fix. Emitted-Drift-Ack-Growth: sync-skills.md — portability fix (#4112): replacing grep -oP '(?<=--from )\S+' with a portable sed -E capture-group equivalent (no PCRE lookbehind available) is a longer expression; growth is the direct cost of the fix, not new functionality. * fix(#3859): pin git commit itself against diff.ignoreSubmodules=all, not just the probe git 2.39.x (the exact version on the CI Linux bench) resolves a pathspec-scoped `git commit -- <path>` through the same diff.ignoreSubmodules-gated machinery as `git diff`, so a genuinely bumped submodule gitlink was silently dropped by the real commit even though the #3859 empty-diff probe correctly saw the change. The commit was misclassified as generic commit_failed because git's refusal text never says "nothing to commit". Prefix the pathspec-scoped commit invocation with -c diff.ignoreSubmodules=dirty, the same override the probe already carries, so the two can no longer disagree. Confirmed on git 2.50.1 (no-op) and git 2.39.5 via the actual gsd-tester-linux v1.8.0-node24 bench image (turns the silent refusal into a commit). * fix(#3859): carry the diff.ignoreSubmodules override via env, not argv The prior commit prepended `-c diff.ignoreSubmodules=dirty` to the real commit's argv, which shifted `commitArgs[0]` off `'commit'` and broke several pre-existing #3859 regression tests (tests/commit-files-pathspec.test.cjs) that assert on the raw argv captured at the execGit seam, e.g. `gitCalls.some((a) => a[0] === 'commit')`. Carry the same override via `GIT_CONFIG_COUNT` / `GIT_CONFIG_KEY_0` / `GIT_CONFIG_VALUE_0` env vars instead, which git honours identically and leaves argv untouched. Re-confirmed on the gsd-tester-linux v1.8.0-node24 bench (git 2.39.5): the submodule commit still succeeds. * test(#3859): pin the commitEnv GIT_CONFIG_* override to canScope directly The commitEnv/GIT_CONFIG_* override added in e935694fc/b3d37b929 was only exercised indirectly through pre-existing submodule integration tests. Add two dedicated regression tests that pin the canScope=false side of the scoping decision: a whole-index commit (no --files) and an --amend commit must both keep recording a bumped submodule gitlink under diff.ignoreSubmodules=all with no override applied, since neither shape carries a pathspec for that git internal check to consult. * fix(#4112): match grep invocations after then/do/else/elif shell keywords lint-portable-grep.cjs's GREP_INVOCATION_RE only anchored to line-start or right after `| & ; ( \` {`, so a grep call positioned right after `then`, `do`, `else`, or `elif` (e.g. `if x; then grep -oP '...'; fi`) was never flagged, letting the GNU-only grep -P defect this lint exists to catch reappear undetected in that shape. * fix(#3859): apply the diff.ignoreSubmodules override to every commit, not just scoped ones The commitEnv GIT_CONFIG_* override landed in e935694fc/b3d37b929 only when canScope was true, on the assumption that git 2.39.5's silent refusal of a bumped submodule gitlink under diff.ignoreSubmodules=all only affects a pathspec-limited `git commit -- <paths>`. Reproduced directly against the pinned CI tester image (ghcr.io/open-gsd/gsd-tester-linux:v1.8.0-node24, git 2.39.5): a bare whole-index `git commit -m ...` with no pathspec at all is refused identically when the only staged change is a submodule gitlink, since git's "nothing to commit" check is a real diff against HEAD that honours diff.ignoreSubmodules regardless of whether a pathspec narrows it. Apply the override unconditionally instead of gating it on canScope; it remains a confirmed no-op for --amend, which never hits this refusal at all. Caught by the new regression test added in 579ac9f8f, which failed against the real bench git version before this change. * fix(#3859): apply diff.ignoreSubmodules override to commit-to-subrepo and pr-subrepo cmdCommit already carries the GIT_CONFIG_* override that forces diff.ignoreSubmodules=dirty on the actual git commit call so a bumped submodule gitlink is not spuriously refused under git 2.39.5. The two sibling multi-repo commit paths, cmdCommitToSubrepo and cmdPrSubrepo, build the identical canScope-branched commit invocation but never carried the override, so the same refusal there surfaces as a generic commit_failed/error instead of a recorded gitlink. Apply the override unconditionally to both, matching the corrected cmdCommit shape. * fix(#3859): pin pr-subrepo's change detection against diff.ignoreSubmodules cmdPrSubrepo discovers what to commit via `git status --porcelain`, which (like the empty-diff probe fixed for cmdCommit) honors a local diff.ignoreSubmodules=all config. Under that config, a genuinely bumped submodule gitlink is invisible to the status scan, so changedFiles comes back empty and the function reports nothing_to_commit before ever reaching the commit call this same issue already fixed. Pin the status probe with --ignore-submodules=dirty, mirroring the flag cmdCommit's diff probe already uses, so a real gitlink bump is detected regardless of local config. Found while adding a regression test for the previous #3859 follow-up fix: the test failed not on the commit step but on this earlier detection step. * docs(#3859): update changeset to cover all three fixed commit sites * docs(#4112): backfill changeset PR number (pr:0 -> pr:4149) --------- 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.
