Message Events - Criminal

Criminal keeps a short in-memory history of messages it sees, which is what makes snipes and deletion logs work.

Message deleted	Cached copy feeds `/snipe`; log entry posted if a log channel is set
Message edited	Previous content available through `/editsnipe`
Message contains `y/n` or `v/s`	Prompt reactions added · Prompt reactions
Message mentions an AFK member	AFK reply · Mentions & AFK

Snipes

/snipe shows the most recent deleted message in the channel, with pagination when several are cached.
/editsnipe shows the last edit’s previous text.
/clearsnipe (,cs) wipes both for the channel · needs Manage Messages.

The cache is memory-only and cleared on restart, so a snipe after a deploy comes back empty. That’s a cache limit, not a bug.

Deletion logs

With a log channel configured, deletions are logged with the author, channel and content when it was cached. Servers with Message logs enabled also keep text and attachment links for 7 days, so a deletion stays readable after Discord’s own cache forgets it · see Server logs.

What it can’t see

Messages sent while the bot was offline, and messages in channels it can’t read, are invisible to all of the above. Enabling the Message Content intent is what makes the cache possible in the first place.
