Reads the most recent messages of a Discord channel (author, timestamp, text), newest first, scrolling up to load more until the requested count. Requires being logged in. Also reads a THREAD or a FORUM POST: both are channels in their own right, so pass the post's url (from discord.com/list_forum_posts) and you get its replies plus the opening post, newest first — there is no separate thread-reading script. It does NOT accept a forum channel itself, which lists posts rather than messages: use discord.com/list_forum_posts for that.
Post a Discord message
Posts a text message in a Discord channel, addressed by channel URL. Requires being logged in to Discord. Returns `sent` plus the created message's messageId, channelId, timestamp and content as Discord stored it. This is a write: the message appears in the channel and is visible to everyone who can see it. Discord's own message limits are checked before anything is sent, so a message that is empty or whitespace-only, or longer than 2000 characters, is refused straight away with a clear reason.
Find Discord member ID by name
Resolves a Discord member's userId from their name, through a channel's mention autocomplete (@name). Useful to build a <@id> ping. Requires being logged in.
