Limits and quotas
The numbers you can run into (Discord's, and Arclo's) collected in one place, with what each of them means for how you configure things.
Discord's limits
These are not Arclo's to change, and several of them explain a design decision elsewhere in this documentation.
| Limit | Value | What it means here |
|---|---|---|
| Slash commands per server | 100 | Shared with your Custom Commands, and why systems group their operations under one command name |
| Message context commands | 5 | Report Message, Stick Message, Remind Me, Add Emojis |
| User context commands | 5 | Moderation History, Warn Member, Report Member |
| Subcommands per command | 25 | /voice uses 25 of them |
| Bulk message deletion age | 14 days | Every purge and auto-purge cap follows from this |
| Timeout length | 28 days | Longer mutes are renewed automatically |
| Channel renames | 2 per 10 minutes, per channel | Why counters update on a 5-minute floor |
| Pins per channel | 250 | A pinned board cannot be pinned in a full channel |
| Components in a modal | 5 | Why a long form is asked across several popups |
| Embed description / total | 4,096 / 6,000 characters | Long placeholders can overflow at send time |
| Buttons | 5 per row, 5 rows | Why a poll stops at 20 options: four rows of choices and one of controls |
| Select menu options | 25 | Dropdown panels, forms, ticket types |
| Interaction token | 15 minutes | How long Arclo has to finish a command and edit its reply |
| Roles per server | 250 | Auto Roles and reward ladders sit well inside it |
Arclo's limits
Per-server quotas. Every figure below is read from the constant the product enforces, so this table cannot fall behind the code.

Things Arclo will not do
- Delete messages older than two weeks in bulk. Discord refuses; deleting them one at a time is rate-limited in hours. They are counted and reported instead.
- Act on somebody above it in the role list. No permission changes that.
- Attribute a vanity URL join to a person. Discord reports the use, not an inviter.
- Change your server's command list the instant you save. Arclo rebuilds and re-registers it within about a minute of a change, and Discord takes a little longer to show it to everybody.
- DM somebody it does not share a server with. Which is why there is no goodbye DM.
Data retention
How long each kind of data is kept is set out in §13 of the Privacy Policy. In short: configuration and records last as long as Arclo is in your server. Removing Arclo marks the server for deletion, and 14 days later everything tied to it is deleted for good; inviting Arclo back within those 14 days restores it exactly as it was. Backups, chat logs and published templates belong to the person who made them, so they outlive Arclo's removal until their owner deletes them.
Still stuck? Ask in the support server: somebody there has almost certainly configured this before.
