* fix(#586): make ship PHASE_VERIFICATION_INCOMPLETE actionable, drop dead `pass` arm The ship preflight gate blocked with PHASE_VERIFICATION_INCOMPLETE but named no next step, and accepted a `pass` status the verifier never emits. Capture the verification status and route per value (gaps_found / human_needed / missing), mirroring execute-phase's status table; accept only `passed`. Closes #586 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(#586): backfill changeset PR number 650 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(#586): scope ship verification status to frontmatter only Codex adversarial review of PR #650 flagged that the status gate grepped `^status:` over the entire VERIFICATION.md, so a `status:` line in the report body (a code block / copied artifact) concatenates into a non-matching value and blocks a genuinely-passed phase with the wrong next action. Restrict extraction to the leading YAML frontmatter block, first match only. Adds a behavioral regression test that runs the gate's own bash pipeline against a passing report whose body contains decoy `status:` lines. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(#586): drop manual PR ref from changeset body The changelog renderer auto-appends `(#<pr>)` from the fragment's pr: field (scripts/changeset/serialize.cjs, github-release-notes.cjs). The manual trailing `(#586)` produced a double, mismatched ref (issue #586 + auto PR #650); remove it to match the sibling-fragment convention. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#586): make ship-586 bash-fence regex Windows-safe (CRLF) The behavioral test extracted the gate's bash block with /```bash\n.../ — a literal \n that fails to match Windows CRLF checkouts and trips the windows-test-parity-guard (fenceRegexLiteralNewline). Use ```bash\r?\n and normalize the captured block to LF before running it. Full unit suite: 0 fail. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#586): run ship-586 bash-pipeline tests on POSIX only On Windows CI the behavioral tests failed: git-bash is present (so the old hasBash guard ran them) but receives a Windows-style tmpdir path it cannot glob, so extraction returned empty. The extraction logic is platform-independent and the gate's bash only runs in a POSIX workflow context, so skip the pipeline execution on win32. POSIX (macOS/Linux) still runs and asserts it.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
