Problem

renderMessageList in message-format truncates results with .slice(0, 25), so message(action=read) and message(action=list-pins) can never return more than 25 items regardless of what the user requests.

Similarly, the channel-list action for MS Teams chats may also be limited.

Expected Behavior

• The limit parameter from the tool call should be respected and passed through to both the Graph API fetch and the rendering layer.
• Support pagination (e.g. before/after cursor or pageToken) so callers can iterate through all messages/chats.
• The .slice(0, 25) cap in renderMessageList should either be removed or made configurable via the limit param.

Location

• dist/message-format-BOXIwUK_.js line 75: messages.slice(0, 25)
• MS Teams provider: Graph API calls for /chats and /messages may also need $top / @odata.nextLink pagination support.
