Which agents work with it?

Any agent that reads skills from a directory. Claude Code, Codex, Antigravity CLI and Grok Build all read /present natively.

What does “free and unlimited” mean?

Generating presentations is free with no cap. Narration runs on your own machine, so there's nothing to meter.

Where does the narration run?

On your machine. The finished presentation publishes to your channel so anyone with the link can watch it.

Do I have to write slides?

You never touch slides. You ask — “brief me on what shipped overnight” — and your agent authors, narrates, and publishes.

Every presentation gets a watch link on your channel. Send the link; it plays in any browser, phones included.

Yes — the /present skill is MIT-licensed, and the authoring spec is public.

On Capy, a Bun pin mismatch used to end in a failing check with no command to run. Now the fix line names the exact install command, and the pinned Bun installs in about four seconds.

Repair

The Capy skill now repairs a pin mismatch on its own

Outside Capy, the fix text is unchanged.

garrytan/gstack · CHANGELOG.md 1.91.99.0

The Capy skill's repair step now covers pins, so an agent following it leaves the machine passing. A pin without a verified Bun stops and names the pin to raise. Outside Capy, nothing changes.

Price

A gbrain LongMemEval call plan now prices in full

Before: judge and reranker unpricedtotal unknown

garrytan/gstack · CHANGELOG.md 1.91.100.0

Pricing a gbrain LongMemEval run used to stop with the total unknown. Now every lane prices, and the sample run with a judge comes to under half a dollar.

Models

Three pricing changes

Dated Claude snapshots bill at their alias's price

GPT-4o is priced: $2.50 in, $10 out per million tokens

Voyage rerankers rerank-2.5 and rerank-2.5-lite are priced

Dated OpenAI snapshots are not folded: some have their own price.

garrytan/gstack · CHANGELOG.md 1.91.100.0

Dated Claude snapshots now bill at their alias's price, GPT-4o has a price, and so do Voyage's rerankers. Dated OpenAI snapshots stay separate, because some carry their own price.
