The web app now uses an agent-written one-line description as og:description on the canvas link preview (full-bleed artifact image + title + description, like a Claude public-artifact link). Add the flag and tell the skill to write it on publish — the agent has the full content in context. - canvas.ts: --description flag, sent in the push body when present. Re-pushing without it keeps the existing description. - SKILL.md: always pass --title and --description on publish; one plain sentence, no marketing voice. Updated the command table and example.

Companion to johnkueh/drafty#1 (the web side).
The canvas unfurl now shows a full-bleed screenshot of the artifact plus a title and
a one-line description — like a Claude public-artifact link. The description is
og:description, written by the publishing agent (it has the full content in context).canvas.ts—pushtakes--description, sent in the body when present.Re-pushing without it keeps the existing one.
SKILL.md— always pass--titleand--descriptionon publish; one plainsentence (~120 chars), no marketing voice. Updated the command table and example.
Depends on the web PR (stores
description, emits the meta tags). Until that ships,--descriptionis simply ignored, so this is safe to merge independently.
