Which agents work with it?

Any agent that reads skills from a directory. Claude Code, Codex and Gemini CLI read it natively; Cursor and VS Code connect over MCP.

The voice runs on your own machine, so there is nothing to meter. The first run downloads it, about 340 MB.

Yes. The skill is MIT-licensed and the authoring format is public.

gstack now installs into Gemini CLI, and draws mockups with Gemini

gstack now installs into Gemini CLI (experimental), and its design skills draw real mockups with Gemini when you have no OpenAI key. Also: older installs drop about 510 MB of test packages, /ship skips a second review loop when only main moved, a .gstack-project file gives a nested repo its own memory, wave PRs for long merge queues, a /freeze path-escape fix, and fixes for false secret alarms, stalled updates and /retro global. Covers gstack 1.92.2.0 to 1.92.22.0 (21 releases, 2026-10-31 to 2026-11-01), for Claude Code users.

gstack now installs into Gemini CLI, with every skill in Gemini's own skills folder. You ask for one by name, like gstack office hours. The host is experimental, and a per-project install is refused.

Without an OpenAI key, /design-shotgun and the other design skills fell back to wireframes. Now they draw real mockups with Gemini, on a free Google key. On the free tier, Google may use your prompts.

Older gstack installs kept about 500 megabytes of test and eval packages they never used. The next setup removes them once, which roughly halves the folder, and puts everything back if the install fails.

A failed install puts the full node_modules back. Marked contributor clones keep everything.

/ship used to rerun its full review, about 19 dollars a time, after main moved or a test changed. Now those skip it, or get one reviewer. A real product change still takes the full loop.
Slide text

/ship stops paying for a second review when only main moved
main moved counted as base, no second loop
tests added one fix-check reviewer, not the full loop
docs fix the fix the docs audit asked for is carried
product edit still the full loop
Each extra loop cost about $19.

gstack filed a nested repo's checkpoints under the outer repo, so /context-restore couldn't find them. An empty .gstack-project file now makes that folder its own project. Above several repos, it gives them one shared memory.
Slide text

A repo inside another repo can now keep its own gstack memory
.gstack-project
nested repo its own checkpoints, learnings and decisions
umbrella several repos share one memory, so a plan carries into the repo you build in
An empty file. Without it, nothing changes.

/freeze only resolved folders that already existed, so a path climbing out through a new folder or a symlink got through. Now it resolves the whole path, and blocks any path it can't place.
