openclaw - 💡(How to fix) Fix Telegram edit action: support editMessageCaption and editMessageReplyMarkup for media messages

Problem

The message tool's edit action always calls Telegram's editMessageText API method. This fails on photo/media messages with:

GrammyError: Call to 'editMessageText' failed! (400: Bad Request: there is no text in the message to edit)

Use Case

We send daily vision board images (photo + caption + inline keyboard buttons). When a user clicks an inline button, we want to update the button label (e.g., "Darren" → "Darren ✅") and style (primary → success) without changing the photo or caption.

Requested Changes

The edit action should detect the message type and use the appropriate Telegram Bot API method:

1. editMessageReplyMarkup — when only presentation (inline keyboard) is being changed, no text/caption update needed
2. editMessageCaption — when editing the caption of a media message (photo, video, document, animation)
3. editMessageText — current behavior, for text-only messages

Suggested logic:

if only presentation changed → editMessageReplyMarkup
else if target message is media → editMessageCaption
else → editMessageText

Current Workarounds Attempted

• Separating buttons into a follow-up text message (worse UX, 2 messages per image)
• Using react action (requires messageId from callback context, not always available)
• Passing caption param to edit (tool requires message field, then calls editMessageText anyway)

Environment

• Channel: Telegram
• Grammy bot framework
• Inline keyboard buttons with callback data
