STET //

Public preview

Your agent stops
and waits for you.

Push a spec. Approve it, or request changes. Your agent reads the verdict and keeps going — or doesn't.

The loop

01 / Your agent pushes

Versioned, immutable content sets. Every push is a new version — nothing is overwritten.

avc push <slug> <file...> --wait
02 / You decide

Approve, or request changes, with notes. Diagrams, files and previews rendered — not a diff.

03 / Your agent reads the verdict

It was blocked. Now it knows, and moves — or revises and pushes again.

avc wait <slug> 
$ avc push auth-spec spec.md --wait
{"slug":"auth-spec","version":3,…}
https://stet.fyi/contents/auth-spec
avc: waiting for review of auth-spec v3 (every 15s, Ctrl-C to stop)… ▋
auth-spec v3  APPROVED  ship it
$

That pause is the product. avc wait <slug> does the same for something already pushed.

Why it holds

  • Diagrams render server-side

    Push a mermaid or vega-lite block in your Markdown; STET renders it to SVG, zoomable and fullscreen. No client JS.

  • Any agent, headless or not

    Per-agent tokens, not a vendor session. An unattended agent on any model can push and block on a verdict — and you revoke one without touching the others.

  • Versioned and immutable

    Every push is a new version — full history, no surprise overwrites.

  • An MCP server, or a tiny CLI

    Point an MCP client at /mcp, or curl one bash script onto your PATH.

  • Previews that tell you when they lied

    STET lints every HTML push and flags what the sandboxed preview can't render — and tells the agent, so it fixes it.

  • Checklists that survive the next version

    Ticks are keyed to the item's text, so they follow it when the agent pushes a new version.

  • Archive, with housekeeping

    Archive what you're done with — one click, undoable.

Setup — agents enroll themselves from an enroll token you generate; no manual wiring per agent. avc enroll, then sign up to get one.

To cancel a marked correction and let the original stand — from the Latin stet, “let it stand.” An editor writes it beside a change they’ve decided to keep.

Here, it’s the one word your agent is waiting for. //
