* fix(#4728): stop presenting the retired Gemini CLI as a supported runtime
#1928 removed the Gemini CLI runtime after Google sunset it on 2026-06-18, and
updated the ENGLISH docs. The locale mirrors and the runtime-loaded workflow
prose were not updated in the same change, and no gate asserts the ABSENCE of a
retired runtime, so both drifted quietly for a year.
The finding that shaped this change: English is already correct. docs/
ARCHITECTURE.md, CONFIGURATION.md, USER-GUIDE.md, how-to/install-on-your-runtime.md
and CLI-TOOLS.md carry zero runtime-axis Gemini references; the only English hits
anywhere are a Gemini 2.5 Pro MODEL line, the GEMINI_API_KEY row, and prose that
correctly documents the retirement. So the docs half of this is translation lag,
not a content decision, and every locale edit here is parity with an existing
English line rather than new wording:
- install-on-your-runtime.md English has NO `### Gemini CLI` section -> deleted
- USER-GUIDE.md :843 "…, Antigravity CLI, Kilo)" -> substituted
- ARCHITECTURE.md English has NO Gemini CLI table row -> row deleted
- ARCHITECTURE.md :24 English holds `Kimi CLI` in that slot -> Kimi CLI
- context-monitor.md :3 "`AfterTool` for Antigravity CLI" -> substituted
- spike-and-sketch.md :93 "(Codex, Antigravity CLI, etc.)" -> substituted
- configure-model-profiles "Codex, OpenCode, Antigravity CLI, or Kilo" -> substituted
- COMMANDS.md English keeps only hyphen + Codex bullets -> colon bullet deleted
- FEATURES.md source docs/features/multi-runtime-support.md:10
lists no Gemini CLI -> name removed
ARCHITECTURE.md:24 is the clearest case for reading English rather than
substituting blind: Antigravity ALREADY appears later in that list, so replacing
Gemini CLI with Antigravity would have named it twice. English holds Kimi CLI
there, so that is what the locales get.
The largest single class was hand-duplicated boilerplate. A "Text mode" paragraph
repeated across 34 runtime-loaded workflow files ends "…required for non-Claude
runtimes (OpenAI Codex, Gemini CLI, etc.)". No lint enforces that sentence and no
script syncs it, so every copy was edited. These files are read by the agent at
runtime, so they steer behavior rather than only informing a reader — which is why
this class matters more than its word count suggests.
The slash-command-form section is restructured in all four languages to match
English, which had already dropped its colon-form bullet. That bullet claimed the
colon form is "Gemini CLI only", which was false on its own terms independent of
the retirement: `/gsd:…` is GSD's canonical AUTHORING token, rewritten per runtime
at install time, and NO runtime registers it — VALID_COMMAND_STYLES is
{slash-hyphen, shell-var} and 18 of 19 runtimes declare slash-hyphen. Substituting
the runtime name would have left the claim false with Antigravity's name in it, so
the claim is gone, matching English.
Two anchor regressions were caught and fixed while doing that. zh-CN lost its
explicit {#slash-command-forms-hyphen-vs-colon} anchor while its TOC still linked
it; the anchor is restored. ko-KR and pt-BR never had an explicit anchor and rely
on the slug generated from the heading text, so shortening the heading broke their
own TOC links; those links now point at the new slugs. English's heading lost its
anchor while its TOC still links the old one — that latent English bug is
deliberately NOT copied.
Preserved, because `gemini` is not one thing here and a blanket sweep breaks the
product: ~/.gemini/antigravity{,-ide,-cli} and ~/.gemini as their parent;
~/.gemini/config (#3738); GEMINI.md; hookEvents "gemini"; GEMINI_API_KEY in all
four locales; every gemini-* model id and the Gemini 2.5 Pro references in
ko-KR/pt-BR/zh-CN (ja-JP genuinely lacks that line — the locales have diverged, so
a uniform patch would be wrong); the hook-event dialect notes, which are
RE-ATTRIBUTED rather than deleted because Antigravity inherits that dialect;
reapply-patches.md:93's legacy-install note; host-integration-capability-matrix.md
:27 and :342, which correctly record the sunset and Antigravity's contract;
whats-new-1.7.0.md and FEATURES.md:3506, which document the retirement itself; and
the generated launcher preamble, which belongs to epic #4632 — zero
_GSD_SHIM_NAME lines appear in this diff.
Coverage: a #4728 block in tests/gemini-runtime-removed.test.cjs asserts the
retired name is gone from STRUCTURAL POSITIONS (a level-3 heading, a table row's
first cell, a runtime-example parenthetical) rather than asserting the string is
absent, which would be wrong. It pairs those with positive PRESERVE assertions
over the same files — Antigravity's heading, ~/.gemini/antigravity, GEMINI_API_KEY,
AfterTool — so a patch that deletes too much fails as loudly as one that deletes
too little. The model-axis test pins both the presence in three locales and the
absence in ja-JP, so a later uniform patch that "helpfully" adds it back fails.
The new docs/ reads tripped lint-docs-guard-registration for the first time in
this file, so the test is registered in scripts/docs-guard-registry.cjs.
Not covered here, by design: nothing above would catch a Gemini-as-runtime
reference appearing in a NEW file tomorrow. That is the repo-wide drift guard,
#4729, which must land last — written now it would red on the very references this
change removes.
Fixes #4728
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(#4728): fix four review blockers, including a vacuous test and my own duplicate
A full matrix run on 31f12d7943 FAILED with 3 real failures, and an isolated
adversarial review returned BLOCK on four blockers. All of it was correct.
1. I committed the exact error I claimed to have avoided. The commit message
boasted that ARCHITECTURE.md:24 proved the value of reading English rather
than substituting blind, because Antigravity already appeared later in that
list. Five hundred lines further down the SAME four files, my
`Gemini:` -> `Antigravity:` substitution produced TWO consecutive
`- Antigravity:` bullets, because an Antigravity bullet was already there.
English (ARCHITECTURE.md:827) merges them into one. Now merged in all four
locales, reusing each locale's existing words.
2. `--gemini` survived in the runtime-detection CLI flag list in all four
locale ARCHITECTURE.md files. English:817 holds `--kimi` in that slot and
already lists `--antigravity` later, so this is another place where
substituting Antigravity would have duplicated it. Now `--kimi`.
3. Two runtime-loaded workflow files still enumerated Gemini one line ABOVE the
line I had already corrected -- the "Adaptive (Recommended)" option in
settings.md:192 and new-project/steps/auto-mode-config.md:95.
4. THE NEW TEST WAS VACUOUS for two of its five files. It matched only
`non-Claude runtimes (` and `(e.g. `, and neither regex could reach the two
lines the change actually fixed: health.md:52 reads `non-Claude (Codex, ...)`
without the word "runtimes", and execute-phase.md:1028 has no parenthetical
at all. The reviewer proved it by re-introducing Gemini at both lines and
watching the assertion stay GREEN. That same blind spot is what hid finding 3.
Replaced with a case-sensitive `/\bGemini\b/` walk over every
`gsd-core/workflows/**/*.md`, which works because every LEGITIMATE gemini
reference in that tree is spelled differently and cannot match: Antigravity's
paths are lowercase with a slash (`~/.gemini/antigravity`), Google's model ids
are lowercase and hyphenated (`gemini-3.1-pro-preview`), and the env vars are
uppercase (`GEMINI_CONFIG_DIR`, `GEMINI_SESSION_ID`). A bare capitalised
`Gemini` there means the retired RUNTIME is being named. The walk asserts it
found at least 50 files so an empty walk cannot pass vacuously, and it now
covers the nested `new-project/steps/` directory where finding 3 lived.
Two allowlist entries, both by line CONTENT and both justified:
reapply-patches.md's `Legacy: ... pre-#1928` note, and settings-advanced.md's
`Known provider` menu. The second was escalated by the agent rather than
decided: Section 8 of that file says model policy is defined "independently"
of the runtime, so `(Claude / OpenAI / Gemini / Qwen)` is the PROVIDER axis --
the same axis as the lowercase model ids -- and must keep working.
Proven to fail, not just asserted: the predicate reports 0 offenders on the
real tree and exactly 2 on a /tmp copy with Gemini re-injected at
health.md:52 and execute-phase.md:1028.
Also from the review: a `| Gemini |` COLUMN survived in the locale FEATURES.md
comparison tables (English has none) -- removed from all three, with header,
separator and every body row kept aligned; two ENGLISH runtime-axis sites were
missed by my own parity standard (how-to/execute-a-phase.md:88 and
how-to/verify-and-ship.md:89, the latter doubly stale since #4716 retired the
Gemini reviewer lane); docs/USER-GUIDE.md:12 linked a dead anchor, which I had
found and deliberately left -- record-and-proceed on a known defect is exactly
what the rules forbid, so it is fixed; docs/COMMANDS.md:12 and all four mirrors
still claimed "the hyphen and colon forms are runtime-specific spellings" with
no colon form documented anywhere, so that false sentence is deleted; and ko-KR
had the installer rather than the user doing the targeting.
The other two matrix failures were the compact-content benchmark baseline, which
drifted because this PR changes byte counts, refreshed via the script's own
`--write` path rather than by hand; and this commit's emitted-drift-ack trailers.
Method note on the acks: the failing run measured growth against
origin/next@1110c3b4ee, which is the STALE LOCAL `next` ref -- gsd-test merges
into the local base branch, and this machine's `next` is seven commits behind
origin/next, which is checked out in the main worktree and so cannot be
fast-forwarded from here. The 32 trailers below are computed against the REAL
base (origin/next @ ca8d9d4459) by comparing each tracked file's blob size, which
is one more file than that run reported -- the extra is settings.md, grown again
by fix 3. docs-update.md and map-codebase.md are deliberately NOT acked: they
SHRANK, since there the fix deleted ", Gemini CLI" rather than substituting, and
acking a file no delta consumed is itself an error.

* chore(#4728): add the changeset fragment
The PR body claimed one was present and it was not — caught by
scripts/changeset/lint.cjs reporting fail_missing_fragment, not by the
checklist, which is exactly why the lint exists.
Type Fixed: the diff is prose, and a docs-only fix uses Fixed since there is
no Documentation type.

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.
