* test(#2725): failing-first coverage for the inert pre-commit alias guard Replaces two stale tests that asserted on `sdk/src/query/command-manifest.phase.ts` — a path retired with the SDK boundary (ADR-0174), so both passed forever while guarding nothing. The new matrix drives .githooks/pre-commit through its GIT_OVERRIDE/NPM_OVERRIDE seams and asserts on the real tracked sources the drift checker reads. Red until the guard is repointed off the gitignored build outputs it currently watches. * fix(#2725): repoint the pre-commit alias guard at sources git can actually stage `.githooks/pre-commit` carried ten staged-path guards and not one of them could do its job. Nine anchored on `^sdk/…`, a tree retired by ADR-0174, and invoked npm scripts that no longer exist (`check:state-document-fresh` and eight siblings). Their only reachable behavior was to abort the commit with `Missing script` — which required matching a path that cannot exist, so they were dead twice over. The tenth was the real defect. Its npm target does exist, but it matched `^gsd-core/bin/lib/command-aliases\.cjs$` — a gitignored build output (.gitignore:172). An ignored path never appears in `git diff --cached --name-only`, so the guard was not stale, it was structurally unmatchable: it watched the derived layer instead of the source layer, from the day it was written. Repointed at the nine tracked `src/*.cts` sources `scripts/check-alias-drift.cjs` actually reads. The family table moves to `scripts/lib/alias-drift-families.cjs` so the checker and the hook derive their surface from one list, and a new parity test fails if a family is added to the checker without the hook learning to watch its source — the rot mechanism, not just this instance of it. Matching is now `grep -Fxqf` (fixed strings, whole line): exact path equality, no regex anchors to get wrong as the list grows. Staged paths are collected into a variable before matching, because `grep -q` exits on first match and would SIGPIPE its upstream, which under `set -o pipefail` turns a successful match into a non-zero pipeline status. The two CONTRIBUTING.md recipes pasted copies of the hook bodies inline — a third parallel surface, and one that had already drifted: the pre-commit copy carried the same dead `sdk/` patterns, and the pre-push copy would have overwritten the committed hook with a paraphrase that drops the GIT_OVERRIDE seam its test drives. Both now just point git at the committed files. The pre-push recipe's `'@example-corp\\.com$'` also never matched anything — inside single quotes bash keeps both backslashes. `.githooks/pre-push` was audited for the same rot and has none: it keys on no paths, no-ops unless GSD_BLOCKED_AUTHOR_REGEX is set, and is covered. Unchanged. Hooks stay opt-in. Nothing registers `core.hooksPath` for you, per CONTRIBUTING.md's documented one-time setup. * test(#2725): make the hook/checker parity assertion bidirectional Review finding from the isolated adversarial pass: the parity row only caught the hook UNDER-watching relative to scripts/lib/alias-drift-families.cjs. Drop a family from the module and the hook would keep watching its source with nothing to notice — the same divergence class this change exists to close, just pointed the other way. The new row takes every `src/*-command-router.cts` on disk as the universe and asserts the hook stays silent for the eight routers the drift check does not read. Both directions are now covered by running the real hook, not by comparing two lists in the test. Also corrects a CONTRIBUTING.md overclaim caught by the standards pass: 9 of the 11 watched paths derive from the module, not all 11 — bash cannot require a CJS module, so the hook carries literals and the test is what binds them. * fix(#2725): ship the shared family table and fix the mock that hid its own rows Three defects the remote runner caught that local probing did not. The mock `git` in the regression test emitted its staged-path payload as `printf '%s' "src/command-aliases.cts\n"`. Bash does not expand `\n` inside a double-quoted string and printf does not expand escapes in a `%s` argument, so the mock produced one unterminated line containing a literal backslash-n. No whole-line match could ever succeed, and every row that expects the hook to FIRE failed while every row that expects silence passed — which is exactly the signature the run reported: 9 failures, all of them fire-expecting rows. The payload now goes through a file the mock `cat`s, which is byte-exact and is what makes the CR-terminated and empty-staged-list rows mean what they say. `scripts/lib/alias-drift-families.cjs` was not enumerated in `GSD_SCRIPTS_LIB_FILES` (bin/install.js:377), so the installer never copied it. That is not cosmetic: `scripts/check-alias-drift.cjs` ships, and it now requires this module — an installed tree would have failed with MODULE_NOT_FOUND the first time a consumer ran `check:alias-drift`. Added to the manifest, which is what the #3184 install/uninstall parity tests assert against `readdirSync`. Regenerated the 19 committed install-tree fixtures via `npm run gen:install-tree` to record the new emitted path. The diff is +1 line per fixture and nothing else. `npm run lint:ci` exits 0. The earlier claim that `scripts/` is outside the emitted surface was wrong: `scripts/lib/` is copied into every runtime's install tree, which is why 19 golden-install-tree cases moved. * chore(#2725): backfill changeset pr: 3273 --------- 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.
