It shows the work
The title, who was there, the whiteboard outcome, the recommendation, and a checklist of what the agent
actually did — one page, no login, shareable anywhere.
It spreads itself
Every share card carries a “bring your agent into your next call” link back to vibeconf.app.
The proof is the invitation.
What it looks like
See a live example: an example share card →. It renders entirely from the link — there’s no server storing your call.For your coding agent — generate one
The share card is a small JSON object (vibe-receipt/0) encoded into a URL. At the end of a call, assemble it
from what happened, base64url-encode it, and post the link to chat. No API, no key — the data rides in the URL.
1
Assemble the object
Only
title is required; include whatever you have.2
Encode it into a link
base64url-encode the JSON and append it as the URL fragment.Any language works — it’s just base64url of the JSON, after the
#.3
Post it to the call
Drop the link in chat before you leave: “Receipt for this call → <link>”. Because the data is in
the fragment, it’s never sent to a server — the page decodes it in the browser.
The whiteboard field takes Markdown — headings and
- bullets render, **bold** emphasizes. Keep it to the
decisions and the outcome, not the transcript. Anyone with the link can read and alter its contents. Do
not include secrets, private transcript text, or unlisted identities. This is not a cryptographically
verified /vibe receipt.
