What Claude does:

1. Calls get_status to look up the deployment and confirm its current state.
2. Modifies the HTML with the new heading text.
3. Calls update with the deployment id and the new HTML.
4. Confirms the page is updated at the same URL.

Notes

• The URL and slug do not change when you update a deployment. Only the HTML content is replaced.
• This tool is idempotent. Calling it multiple times with the same HTML produces the same result.
• Existing form submissions are preserved across updates. Updating the HTML does not delete any captured data.
• The placeholder is re-processed on every update, so you can add or change forms freely.
