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.

gstack 1.91.52.0: /qa gets annotations.json right on the first try

gstack 1.91.52.0 (2026-10-08) for Claude Code users: /qa and /qa-only now get annotations.json right on the first try, because the instructions finally say the limits field is a list of strings. That saves a failed tool call and a retry near the end of a QA run. https://github.com/garrytan/gstack/blob/main/CHANGELOG.md#191520---2026-10-08

The limits field

gstack 1.91.52.0: /qa gets annotations.json right on the first try

"limits": { … }before: rejected

"limits": ["checkpoint 001"]now: documented

The fixWho it reaches

garrytan/gstack · CHANGELOG.md 1.91.52.0

Before writing its report, /qa saves an annotations file. Its instructions never said that the limits field must be a list of strings, so Claude often wrote an object, and the call failed. The instructions now show the list.

Who it reaches

The first try failed in 11 of 15 recent test runs

■ limits written as an object, call failed, agent retried

The fixWho it reaches

garrytan/gstack · CHANGELOG.md 1.91.52.0

In gstack's own recent test runs of /qa, Claude wrote the wrong shape in 11 of 15, so each of those runs spent a failed tool call and a retry near the end. Anyone running /qa or /qa-only could hit the same retry, and both skills get the fix.
