Post a Discord message
Input
message requiredText of the message to post. Discord refuses empty messages and anything over 2000 characters client-side, so both are rejected up front.
channelUrl requiredFull channel URL, e.g. https://discord.com/channels/<guildId>/<channelId>
Output
sent requiredcontent optionalContent as stored by Discord.
channelId optionalmessageId optionalID of the created message (from Discord's API response).
timestamp optionalRead Discord messages
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.
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.
Discord login
Opens the Discord web app in the browser and reports whether the account is signed in, together with the username and display name it is signed in as. Run this first: the other Discord scripts need the web app open on a signed-in session.
