Any thoughts to share the record to the user whom we mentioned @someone in the chatter posting. I know we can do somethng with the feeditem trigger.

thanks for the suggestion. I am able to achieve this by writing a trigger on feeditem using connectapi apex classes. find the sample code to retrieve the user ids of @mentioned users.

ConnectApi.FeedItem feedItem = ConnectApi.ChatterFeeds.getFeedItem(communityId, feedItemId);
List<ConnectApi.MessageSegment> messageSegments = feedItem.body.messageSegments;
for (ConnectApi.MessageSegment messageSegment : messageSegments) {
if (messageSegment instanceof ConnectApi.MentionSegment) {
ConnectApi.MentionSegment mentionSegment = (ConnectApi.MentionSegment) messageSegment;
System.debug('Mentioned user name: ' + mentionSegment.name);
System.debug('Mentioned user id: ' + mentionSegment.user.id);
}
}

SFDC doesn't store the user Id in feedItem past when using @mention. So you will have to dependent on Custom Parsing. In trigger code, you will have to parse the feedItem body and split user's name from that. Once getting user full name, do a SOQL query to fetch the user id and then create a sharing record.
One issue with this approach is, if there are 2 users with the same name, you can not identify which one was in @mention.
