* test(#3854): write normalization must preserve tight multi-line lists (failing first) * fix(#3854): no blank before a bullet whose previous line is an indented continuation _normalizeMd's 'separate a list from a preceding paragraph' rule inserted a blank before any bullet whose previous line wasn't a bullet — but an INDENTED CONTINUATION of the previous multi-line item also isn't a bullet. Every .md write (phase.complete in the report, but any write through platformWriteSync) therefore converted tight lists to loose ones: +61 blank lines on the reporter's 1015-line ROADMAP, one before each bullet following a wrapped item. Tight and loose lists render differently, so this was a rendering change plus misleading diff noise; one-shot (idempotent afterwards), which is why integrity checks on headings/content passed. The guard is the mirror image of the after-a-bullet rule two lines below, which already excludes indented next lines. Paragraph→list and heading→list separations — the rule's purpose — are pinned unchanged by the new suite. * fix(#3854): review fold-ins — ceiling tracks next's 281 + this branch's marker (282), header/require nits The ceiling is not ratcheted but must track the tree: origin/next raised it to 281 (sibling branch's marker file); this tree adds one more (shell-command-projection-md-normalize), so 282/282. Also fixes the test header's stale pre-rename filename and hoists the inline require to the file's single import. * chore(#3854): changeset fragment (pr number backfilled after PR creation) * chore(#3854): backfill changeset PR number (4049) --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.

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
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

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.
