* test(#4145): regression rows for hash-matching prefix-less pristine baselines RED skeleton: src/pristine-baseline.cts exports findPristineByHash as a null-returning stub so the new rows fail behaviorally, not at require time. Failing-first rows: verifier resolution (no_baseline must drop to 0 when an exact-hash orphan exists), findPristineByHash unit row, and the two saveLocalPatches relocation rows. Negative-space rows pin today's behavior: missing baselines still report ok_no_baseline, mismatching orphans are never adopted or deleted, canonical precedence and the #3657 drift posture are untouched. * fix(#4145): resolve gsd-pristine/ baselines by recorded hash, relocate orphans Both pristine readers joined the manifest-keyed path strictly, so a snapshot stored without the gsd-core/ prefix (an earlier release's writer) was reported as ok_no_baseline by the verifier and pushed into regeneration by saveLocalPatches — where incoming-release candidates can never satisfy the recorded outgoing hash, leaving the correct baseline permanently unconsumed. - src/pristine-baseline.cts (new, ADR-457): shared findPristineByHash — deterministic sorted scan of gsd-pristine/, exact sha-256 equality with the recorded pristine_hashes entry (the same authority the #3657 drift guard trusts), symlink-skipping, canonical path excluded via skipRel. - verify-reapply-patches.cjs verifyFile(): on canonical miss with a recorded hash, adopt byte-identical content found anywhere under gsd-pristine/ before reporting OK_NO_BASELINE. Drift posture (#3657), canonical precedence, and the frozen REASON/report shapes are untouched; the verifier stays read-only. - install.js saveLocalPatches(): preserve-check rescue — relocate a hash-matching orphan to the canonical path (copy, hash-verify, then remove the orphan) so the state self-heals on the next update instead of repeating forever. Honest accounting: new non-overlapping rescued counter. - Workflow doc: one-sentence note on hash-based snapshot resolution. - Derived ripples: INVENTORY-MANIFEST.json regen, eslint ignore + .gitignore entries for the compiled artifact, seedFixture mkdir fix in the new rows. Emitted-Drift-Ack-Growth: reapply-patches.md — one-sentence note on hash-based pristine snapshot resolution (#4145) * fix(#4145): review follow-up — orphan scan never consumes a canonical path Adversarial review finding: with two modified files sharing byte-identical outgoing content, recoverOrphanedPristine could adopt the OTHER file's canonical pristine as its rescue source — relocating it (copy + delete at its home path) and ping-ponging the single baseline between the two files across updates. findPristineByHash's skip parameter now accepts a Set, and saveLocalPatches passes the normalized manifest keys so every canonical path is excluded; only genuine non-canonical orphans are eligible for removal (no strict-join reader ever consults those). Adds the canonical-theft regression row, a Set-skip unit assertion, and tightens the workflow doc sentence the same pass flagged as overstated. * fix(#4145): INVENTORY roster row + symlink-fixture correction Two leftovers from the ab17b7a1e5 bench run, both root-caused: - docs/INVENTORY.md roster row for cli_modules/pristine-baseline.cjs (#3762 gate: every manifest entry carries a row). - The findPristineByHash symlink unit fixture placed its symlink target INSIDE the scanned root, so the walk legitimately matched the real target file. The implementation skips the symlink itself; the fixture now keeps the target outside the scanned tree so the assertion tests what it claims. * changeset(#4145): fixed fragment for pristine baseline hash resolution --------- Co-authored-by: gsd-agent <agent@gsd.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.
