* fix(#2903): use the command form that actually works in reader-facing docs Docs told readers to type the colon form, which no runtime registers -- 18 of 19 runtimes use slash-hyphen and the 19th uses shell-var -- so anyone copying an example got an unrecognized command. Swept 178 occurrences across 53 files, locale mirrors included so they do not re-diverge from English. The colon form is a source-authoring token, not a user-facing one: install-time converters key on it to produce the hyphen form runtimes actually register. So the sweep is scoped, and three things are deliberately left alone: - ADRs, which are a historical record; editing their prose falsifies what was written at the time. - The legacy release-notes archive, pending a maintainer decision on whether it follows the same historical carve-out. Excluding it keeps a later reversal additive rather than a revert. - Source artifacts under commands, workflows and agents, where the colon form is load-bearing. Rewriting those would break the installed-skill guarantee across every runtime -- the single largest hazard here. The plugin namespace form is a real, separate token and survives untouched. Adds a lint enforcing exactly that boundary, since the correct form genuinely differs by directory and nothing previously caught the drift. Also fixes a hardcoded colon form in the capability-matrix generator. The sweep alone would have left the generated matrix disagreeing with the template that produces it, so the fix is at the source and the output regenerated.

That key genuinely is the colon form -- this change's own carve-out logic says source-authoring tokens keep it -- so the docs ended up misquoting the real files. One of the three is an acceptance-checklist assertion, which the sweep turned into a false statement. Restored the three citations to match their sources verbatim, surgically: where a line carried both a name: citation and a real reader-facing slash command, only the citation reverted and the command stayed corrected. The guard needed the same distinction, or it would have flagged the restoration and reddened the build: a gsd:<cmd> token preceded by name: is a citation of a source token and is now permitted. The exemption is deliberately narrow -- a bare gsd:<cmd> anywhere else still fails -- with a test pinning that narrowness. Also makes the detection case-insensitive. Review found /GSD:next slipped through silently; no such casing exists in the tree today, so this closes a latent gap rather than fixing a live one. Swept the whole tree for further corrupted citations: none beyond the three. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2903): retire the stale-next invariant and sweep next like every other command Maintainer decision on a genuine conflict between two contracts. Invariant #3054 banned the literal /gsd-next from user-facing docs because it named a retired workflow-advance command. But commands/gsd/next.md is a live command -- the state-aware smart-entry launcher -- and this issue requires docs to use the hyphen form every runtime actually registers. Both could not hold for this one command, so docs had been sidestepping the ban by keeping the colon form, which is exactly the defect this issue exists to remove. FEATURES.md already recorded the reassignment: the hyphen form "is not the retired workflow-advance command; it is reserved for the state-aware smart-entry launcher. Workflow advancement remains under /gsd-progress --next." With that reassignment the invariant's premise is obsolete and the guard now contradicts the documented command form, so it is retired with a comment recording why rather than deleted silently. next is now swept like every other command, and the earlier exemption added to the new guard is removed so nothing is special-cased. Four citations of the literal name: frontmatter key stay in colon form, because the source file really does carry name: gsd:next and a doc quoting it must reproduce it verbatim. Two of those lines were reworded to say which side is the frontmatter key and which is the slash command, since they previously conflated the two. Verified the retired scan would now genuinely fail against this tree -- the conflict was real and resolved, not dodged.

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.
