How to post to X from Claude

  1. Add Social Rainbow to Claude

    Start the Social Rainbow trial, then open the connectors directory, find Social Rainbow, choose Connect, and sign in with the same Social Rainbow account.

  2. Connect your X account

    Choose the X connection and complete the provider's authorization page. Return to Claude and list accounts again to confirm the connection.

  3. Draft for X

    Keep one sharp idea per post and remove throat-clearing. Use a thread only when the idea truly needs ordered steps. Include any intended link or supported media before validation.

  4. Validate and review the exact preview

    Check every destination, the visible post text, link behavior, media, follow-ups, and platform options. Resolve warnings or errors before approval.

  5. Approve and publish

    Explicitly approve that exact preview. Social Rainbow publishes the unchanged payload and returns the actual publication job status.

A prompt you can copy

You do not need to name internal tools. State the outcome, destinations, source material, and approval requirement in plain language.

Example prompt for Claude“Adapt this into a X post for my connected X account. Validate the final content, and show me the exact preview before publishing.”

Write for X, not just at it

Keep one sharp idea per post and remove throat-clearing. Use a thread only when the idea truly needs ordered steps.

Supported content: text, link, image, GIF, and video posts. Media is optional for X posts.

Media handling in Claude

For media posts, provide a direct public media URL that Social Rainbow can validate for the selected destination.

Media storage does not publish a post. The assistant still has to validate the destination, show the complete preview, receive approval, and call the final publish or schedule action.

What the final review should show

  • The exact connected account name and destination.
  • The final visible root post and any follow-ups or comments.
  • Every link, media item, and destination-specific option.
  • Warnings, normalization changes, or validation errors.

If anything changes after that review, validate the new version and approve it again. This keeps the user's approval tied to the content that will actually be sent.
