A GitHub Action to publish Visual Studio (the IDE) extensions (.vsix) to the Open VSIX Gallery. This is not for VS Code extensions.

Works on both Linux and Windows runners. Uses curl and bash — no PowerShell or extra dependencies required.

- name: Publish to Open VSIX Gallery
  uses: madskristensen/publish-vsixgallery@v1
  with:
    vsix-file: path/to/MyExtension.vsix

After a successful upload the action writes a workflow run summary containing the gallery badge, the extension page link, and a manage link that lets you delete the extension yourself from the gallery. Quality warnings returned by the gallery are shown as workflow annotations. Warnings do not fail the publish step.

Every extension can be deleted from its gallery manage page (https://www.vsixgallery.com/extension/<id>/manage). Access is gated by a per-extension manage token — it's a soft "don't let randos delete my listing" speed bump, not strong authentication.

• First upload, no manage-token supplied: the gallery auto-generates a token and embeds it in the manage URL printed in the workflow run summary. Save that URL — the token isn't shown anywhere else.
• First upload, manage-token supplied: the gallery uses the value you supply (typically a GitHub Actions secret). The manage URL won't contain it.
• Republish, no manage-token: the existing token stays in place. The manage URL won't contain it.
• Republish, manage-token supplied: the value you pass becomes the new manage token, replacing whatever was on file. Lost your old token? Just republish with a fresh one and the new value takes over.

The token is always masked in workflow logs.
