* test(#1856): failing-first contract for the orchestrator cwd-drift guard handoff The #48 guard correctly refuses to execute waves from an agent worktree, but the refusal is a dead end: that worktree can hold committed fixes AND uncommitted work, and "re-run from the orchestrator's own worktree" silently means abandoning them. The reporter was left choosing between continuing from a blocked worktree and losing the work. The guard is shell embedded in execute-phase.md, so these tests extract the block by a stable marker and EXECUTE it against real git fixtures — the shipped text is the runtime contract. Covers the stranded-commit and dirty-tree report, the integration commands, both agent- namespaces, commit-count boundaries 0/1/2, and the constraints the guard's own comment records: it must NOT fire on an ordinary branch, on 'agentic-refactor', or on a legitimate feature worktree under .claude/worktrees/, and must degrade cleanly with no resolvable base or a detached HEAD. RED expected: the marker does not exist, so extraction fails and every case errors.

The defect is that it was a dead end. At the moment it fires, the worktree can hold committed product work, uncommitted product and planning changes, and the live gap-planning context. Telling the user to "re-run from the orchestrator's own worktree" silently means abandoning all of it, because the orchestrator worktree cannot see commits that live only on the agent branch. The reporter was left choosing between continuing from a blocked worktree and losing five commits plus uncommitted work. The refusal now reports what is actually stranded — the commit count and log against the resolved base, and the uncommitted files — followed by the concrete integration sequence (commit here, switch to an orchestrator-safe checkout, merge or cherry-pick, re-run) and a verify command. Nothing is claimed that is not there: a clean worktree with no commits ahead prints the plain refusal with no empty sections. Every added command is diagnostic and `|| true`-guarded, so a failure degrades to the original refusal rather than crashing before the message prints. Verified: an unresolvable base still refuses cleanly. Deliberately NOT done: auto-merging or auto-cherry-picking the agent branch. That is precisely the operation #48 exists to stop the orchestrator performing from a drifted cwd, at the moment it has least confidence about which tree is which. Reporting beats acting here. The guard block carries a `gsd:guard=orchestrator-cwd-drift` marker so the new contract test can extract and EXECUTE the shipped shell against real git fixtures rather than asserting on its characters. Fixes #1856 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DPq9ovaovP2UvSVLjD4Lso * fix(#1856): report true counts, add the changeset, and document the seam Review findings, all from the isolated adversarial pass: - The dirty-file list was capped at 20 with no indication, so a worktree with 27 uncommitted files reported 20 — under-informing the user about exactly what is stranded, which is the entire point of this change. Both lists now count BEFORE truncating and print "… and N more". Verified with 25 commits / 27 dirty files. - The has-commits condition was written out twice and could drift on a future edit. Collapsed to a single _WT_HAS_COMMITS flag. - The changeset fragment existed but was untracked, so it was in neither commit on this branch and the PR gate would have failed against real history. - CONTEXT.md:122 documents this exact seam ("the orchestrator runs a cwd-drift guard at execute_waves entry…") and was not extended. Now records the handoff report, that the refusal condition and exit code are unchanged, and that every added command is diagnostic and || true-guarded. Verified NOT a defect, correcting the review's premise: the guard block does break when its line endings are CRLF, but .gitattributes:2 is `* text=auto eol=lf`, which OVERRIDES core.autocrlf and forces LF on checkout on every platform including Windows — so the shipped file is LF there too, and the installer copies it through Node without translating endings. The reproduction (mine and the reviewer's) required injecting CRLF by hand. It is also not fixable from inside the script: a \r breaks the shell parse at the block's first line, before any #1856 code runs. Neither introduced nor amplified by this change. Also noted and left as-is by design: the review flagged that #1856's "offer an explicit recovery option" could be read as requiring an interactive/automated integration rather than printed instructions. Deliberate — see the commit that added the block: auto-merging is the exact operation #48 exists to prevent the orchestrator performing from a drifted cwd. Called out in the PR body for a maintainer decision rather than silently chosen.

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.
