Command

Every command flow begins with a Command block. It defines how users invoke the flow in Discord and what metadata Discord shows in autocomplete. This block is placed automatically by the builder. You cannot add it from the block palette.

​

What it does

Listens for a slash command, prefix command, or context menu action and starts the connected blocks. The Command block is the root of the canvas: you cannot delete it or add another from the palette.

​

Common uses

• Slash commands — Register /ping style commands with Discord descriptions and options.
• Prefix commands — Run flows when someone types !help or your configured prefix.
• Context menus — Right-click a user or message to run a flow from the apps menu.

​

Configuration

Open the block in the builder sidebar to configure these fields.

​

trigger_type

Type: string. Required. How users start this flow. Accepted values: slash, prefix, user, message.

​

friendly_name

Type: string. Required. Title on the canvas card and in your command list.

​

discord_name

Type: string. Slash command name Discord registers. Lowercase, no spaces.

​

discord_description

Type: string. Shown in Discord slash command autocomplete.

​

prefix_command_name

Type: string. Word after your prefix (for example ping in !ping).

​

prefix_command_aliases

Type: list. Up to five alternate prefix names that run the same flow.

​

safe_test_mode

Type: boolean. Skips destructive steps (moderation, API calls, Ask AI, persisted variables) and posts a short notice instead.

​

Example workflow

1. Pick a trigger type — Slash is the default for new commands. Use prefix if your server relies on a text prefix.
2. Name the command — Set a friendly name for your dashboard, then the Discord-facing name and description.
3. Add options (slash only) — Attach Command option blocks under the Command node for typed parameters.
4. Connect actions — Draw a connection from the bottom handle to your first action block.

​

Tips

• Enable Test mode while building flows that touch roles, channels, or external APIs so you can run them safely in a live server.
