Edit Discord message
TL;DR
About
In the Discord app you hover over the message and click the pencil, or press the up arrow to edit your last one. You would only hand this to an agent already doing Discord work for you, when the fix is part of that job. Say the meetup announcement in #announcements went out with 8pm instead of 9pm. Copy its link (right-click, Copy Message Link) and send the full corrected text. You get back what Discord saved, plus previousContent with the old wording as the edit box showed it. The catch is that an edit pings nobody. Anyone who saw 8pm in a notification still has 8pm in their head, so a short reply under the announcement (discord.com/reply_to_message) does more than the (edited) tag. Your text replaces the whole message and is capped at 2000 characters, even though Nitro accounts can post 4000. Only your own messages in server channels and threads can be changed, not DMs.
Input
content requiredThe full replacement text. This replaces the message entirely, it does not append.
messageUrl requiredFull url of your own message, e.g. https://discord.com/channels/<guildId>/<channelId>/<messageId>. discord.com/read_messages or discord.com/search_messages return the ids to build one.

}FAQ
Search Discord server messages
Search one Discord server's message history with Discord's own search, as the signed-in account, newest first. Search by words (content), and narrow by authors, channels, mentioned users and content type, each given as ids: get user ids from discord.com/get_member_list and channel ids from discord.com/list_channels. Returns one page of up to 25 matching messages with their author, text, time and link, Discord's total count of matches, and next_offset to read the next page (null on the last one). Fails with a clear error when the browser is not signed in to Discord, when the account is not a member of the server or can see no text channel in it, or when Discord is still indexing the server. Direct messages are not searched.
Read Discord messages
Reads the most recent messages of a Discord channel or direct message (author, timestamp, text), newest first, scrolling up to load more until the requested count. Requires being logged in. A DM or group DM is read the same way: pass its url from discord.com/list_dms. It also reads a thread or a forum post, since both are channels in their own right: 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. To list the posts of a forum channel rather than its messages, use discord.com/list_forum_posts instead.
Post a Discord message
Posts a text message, optionally with a file attached, in a Discord channel addressed by its URL. Requires being logged in to Discord. Returns `sent` plus the created message's messageId, channelId, timestamp and content as Discord stored it. The message is visible to everyone who can see the channel. Empty messages and messages over 2000 characters are refused with a clear reason. Use dry_run to check a channel and message without posting.
