* test(#2845): failing-first suite for UI-SPEC inventory provenance Binds two shared formats before either exists, so the suite is RED against next: the gsd-ui-checker dimension roster (asserted independently on twelve surfaces, eight English and four translated) and the provenance-line grammar the UI-SPEC template emits and Dimension 7 consumes. Every parity assertion is paired with a synthetic mutation case, so the guard's failure branch executes rather than only reading a correct tree: limit-1 (a surface still declaring 6), limit (7), limit+1 (8), a dropped dimension, a label that drifts on one surface only, a non-contiguous roster, a duplicated number, and a surface that stops declaring a count at all. A seeded fast-check property renders the roster under formatting noise (CRLF, padding, interleaved sections) and asserts the parse round-trips and is strictly sensitive to a dropped heading. Assertions are on parsed typed records, never raw substrings. * docs: normalize design-a-ui-phase how-to to American English House style for docs/ is American English (CLAUDE.md). This file carried colour/initialisation/initialise/artefact throughout. Spelling only — no content change; kept separate from the #2845 feature commit so the release-notes classifier and the hotfix cherry-pick filter see it for what it is. * feat(#2845): require provenance for UI-SPEC component inventories A UI-SPEC's component inventory was treated downstream as a closed allowlist while the document recorded nothing about whether the list had been enumerated from the installed design system or recalled from memory. A recalled inventory is indistinguishable from an enumerated one, so an executor complying with the spec builds against a fraction of what the package offers, and every gate stays green because they assert semantics rather than composition. The UI-SPEC template gains a Component Inventory slot carrying one of two provenance lines: the command that enumerated the list, the count it returned, the resolved package@version and the date; or a Could not enumerate record with a real reason. gsd-ui-researcher gains an enumeration ladder and must record the line rather than write the list from recall. gsd-ui-checker gains Dimension 7. An inventory with no provenance line, a count with no command, an empty could-not-enumerate reason, or a line still carrying the template's unfilled placeholders BLOCKs; a partial line, a line placed below its table, or an honest negative record FLAGs; a complete line passes, and so does a spec carrying no inventory at all, which keeps every UI-SPEC predating the dimension validating unchanged. Whatever the verdict, an unsourced inventory is reported as a non-exhaustive list of known-good components rather than a closed allowlist, so the executor is never blocked from a component the spec merely failed to mention. The checker never runs the recorded command. The dimension count moved on all thirteen surfaces that assert it, across five languages. Also corrects the claim in the English, Korean and Portuguese how-tos that this checker applies a scored six-pillar rubric — that rubric belongs to /gsd-ui-review's retroactive audit. * chore(#2845): backfill changeset pr number to 3745 --------- Co-authored-by: sim <sim@local>
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.
