update-site

Update the VibePad website: upload the new DMG for the download button and add an appcast entry for Sparkle auto-updates.

Gathering info

Ask the user for any values not provided as arguments or inferrable from context:

1. •Version (e.g. 1.1) — the sparkle:shortVersionString
2. •Build number (e.g. 2) — the sparkle:version
3. •EdDSA signature — the sparkle:edSignature="..." value from sign_update
4. •File length in bytes — the length="..." value from sign_update

If the user just ran /release, these values should be available in the conversation context — use them without asking again.

Steps

1. •

   Read the current appcast: Read /Users/vyuignatiov/code/vibepad-site/appcast.xml.

2. •

   Replace the existing <item> entry in <channel> with the new version's data. Use this format:

    <item>
      <title>Version {VERSION}</title>
      <pubDate>{RFC 2822 date, e.g. "Sat, 08 Feb 2026 12:00:00 -0800"}</pubDate>
      <sparkle:version>{BUILD_NUMBER}</sparkle:version>
      <sparkle:shortVersionString>{VERSION}</sparkle:shortVersionString>
      <sparkle:minimumSystemVersion>14.0</sparkle:minimumSystemVersion>
      <enclosure
        url="https://vibepad.now/assets/VibePad.dmg"
        type="application/x-apple-diskimage"
        sparkle:edSignature="{ED_SIGNATURE}"
        length="{FILE_LENGTH}"
      />
    </item>

Use the current date/time for <pubDate>. Replace (don't stack) — the site serves a single DMG at a stable URL, so old entries would have stale signatures/lengths. Sparkle only checks the newest compatible item anyway.

1. •Copy the DMG to the website assets (stable filename for the download button):

cp "/Users/vyuignatiov/code/VibePad/VibePad-${VERSION}.dmg" "/Users/vyuignatiov/code/vibepad-site/assets/VibePad.dmg"

1. •Commit and push the vibepad-site repo (auto-deploys on push):

cd ~/code/vibepad-site && git add appcast.xml assets/VibePad.dmg && git commit -m "Update to VibePad ${VERSION}" && git push

1. •Report to the user:
   • •Show the updated appcast entry
   • •Remind them to verify at https://vibepad.now/appcast.xml
