* test(#4384): failing-first regression rows for the macOS long-base todo-cap failure The 240-char pending-todo bullet cap must be deterministic w.r.t. where the repo is checked out. Deterministic long-base-path fixtures (a single 110-char segment, no real macOS dependency) reproduce next's own macos shard 3/3 failure (run 34038716700) on every OS: with an absolute link the bullet exceeds the cap and the documented needs-first truncation drops the 'Needs <solution>' clause. Rows cover the determinism property (byte-identical bullets under short and long bases), the CLI surface, relative-path stability, legacy no-projectRoot behavior, drop-order preservation, and adversarial edges (outside-root, path===root, non-string path). * fix(#4384): render the pending-todo bullet link repo-relative renderPendingTodosMarkdown gains an optional projectRoot; when given and the todo's path is absolute, the bullet's [todo file](…) target becomes toPosixPath(path.relative(projectRoot, path)) — the idiom already used for project_exists. cmdInitTodos passes cwd. The JSON todos[].path field stays absolute (#2376). Only the rendered display link changes: embedding the machine-variable absolute base let macOS's /private/var/folders/… temp paths consume the 240-char budget and drop the 'Needs' clause on long-path machines only — next's own macos-latest shard 3/3 went red on exactly this (run 34038716700), Linux's short /tmp passed. The 240-char whole-bullet cap and the needs→title→area drop order are unchanged; this matches PR #4384's own canonical example, docs, and unit tests, which all show repo-relative links. Docs updated at all three surfaces that describe the bullet (COMMANDS.md, templates/state.md, reference/state-md.md — the last was still pre-#4384 'count and reference' prose). Fixes the macOS regression introduced by #4384; next is red on its own CI. * test(#4384): fix substring false positive in the outside-root regression row The ../-form relative link legitimately contains the absolute path as a substring, so !line.includes(absolutePath) fired on correct output (caught by the first remote verify run, linux-node24 44018/44019). Assert the property itself instead: extract the link target and require it to be non-absolute and not equal to the absolute path. * chore(#4398): backfill PR number in changeset --------- 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.
